Errata
Dive Logs:
ROPOS dive logs were saved in .html or Excel .csv (comma delimited) files. The .html files were not an option for editing, as they can only be saved as text files, and lose all their rows and columns. The .csv files were a little easier to work with so they were the files edited for the dive logs. (As you may recall, we could not edit the logs at sea.) There was a problem with the .csv dive log files as well. Any double letters or double numbers were absent. I tried to find those errors and correct them, but be aware, especially regarding numbers, as those errors were particularly hard to spot.
Navigation in general:
1999 navigation not as robust as 1998. 1999 nav fixes were often to the west or southwest of '98 fixes. Unfortunately this is not always the case. The farther south we went, the worse the acoustic nav. That is because the southern transponder net could not be calibrated with the ASHES net. (See section 4 for more details.) Be aware of that and use the dive plots as a guide.
Dive Plots:
R492 Missing acoustic nav at end of dive, after JD183 2130. We weren't getting any fixes, and there were no good fixes recorded in the nav logbook to supplement the acoustic fixes. The dive continued for a couple more hours, ending about 250 meters southeast of Bag City. Will fill in last two hours of nav with adjusted ship nav, eventually.
R494 Video went out at JD185 1810, therefore there was no bottom image from that time until ROPOS came up. 1810 official end of dive.
R495 There are gaps in the nav from JD186 1454 - 1640 and 2236 - JD187-0000. We were getting out of the range of the ASHES net transponders. The dive plots just show a straight line connecting the times. Acoustic nav ends on JD187 0115, but the dive continued until 0158. All the nav gaps will be filled with adjusted ship nav, eventually.
R501 No acoustic nav from JD191 2251 - JD192 0521. ROPOS on the deck or in the water column from 0230 - 0530. Need to fill in JD191 2251 - JD192 0230 with adjusted ship nav, eventually. The dive plot shows the ROPOS track from JD192 1411 - 1520, but ROPOS was transiting off the bottom at the time and there was no video.
R494 and R497 Plots state that the nav fixes for the ship are at the stern. That is not accurate. We presume the GPS fixes were referenced to the GPS antennae, about 37 meters fore of the stern. To get actual position at stern one would have to apply a 37 meter lay-back to the ship navigation. (To confuse the matter more: Navigation fixes transcribed in the nav logbook are positions at stern, because we put the pointer in that position on the nav screen and wrote down that fix. More information than you want to know?)

1 OVERVIEW OF NeMO'99 - Bob Embley
During the NeMO99 cruise, ROPOS recovered more than 260 geologic, biologic and chemical samples, retrieved 29 experiments and and instruments, and deployed 25 experiments. ROPOS made 18 successful dives totaling 204 hours of bottom time in 21 days on site. Despite major problems with the hydraulic systems on the ROPOS, which caused us considerable downtime, the hardworking ROPOS team and the efforts of the science party were able to recover to make this year's cruise rival the success of NeMO98.
The chemical and biological effects of the 1998 diking event are still apparent on the eastern side of the caldera where the lava flow was erupted. Vigorous hydrothermal venting continues in many places (e.g. Marker 33, Cloud, and Magnesia), whereas there has been reduction or cessation in others. Although the amount of visually apparent microbial activity (such as the white floc in the water column) decreased, "snowblower" activity continued at some vents (e.g. Magnesia Vent) and hyperthermophilic microbes were again found in abundance at most of the diffuse (low temperature) sites, (whose temperature is well below their optimal growth rate). These observations show that there is still enhanced subsurface microbial growth more than a year and a half after the eruption. Of particular interest was the discovery of a hyperthemophile growing optimally at 102C.
Colonization of the new vents continued. Tubeworms had arrived at Marker 33 and were present in greater densities at sites that only contained small patches in 1998 (e.g., Nascent Vent). Analyses of the water samples, biological grabs, and video observation should tell us much about the evolution of the chemical and biological systems on the summit of Axial.
Mapping of the new lava flow and associated hydrothermal system continued in 1999. We located the (probable) southern end of the lava flow about 6 kilometers south of the caldera along a spectacular fissure system that was followed for hundreds of meters. The eruption was entirely contained in the 1 to 2 meter wide fissure until it overflowed its fissure and erupted in the large mound of lava that was found in 1998 at 4552'N. Farther north towards the caldera, the trace of the 1998 eruption became more confused as the slightly older eruptions mixed with the 1998 lava. Several new vents (Bag City, Crevice, Coquille) were found south of Marker 113 (the southernmost point investigated in 1998). The vent fluid sampler recovered 113 water and filter samples from all the (still active) major vents.
The ASHES vent field was only visited on two dives in 1999 because of the early downtime of ROPOS, and part of one dive was again spent at the CASM vent field in the northern part of the caldera.
Active hydrothermal venting was only found on the summit of Axial, probably where the underlying zone of molten lava permanently resides. The summit area contains hydrothermal systems formed during several different volcanic or tectonic (earthquake generated) events, providing a natural laboratory for studying colonization and evolution of these unique chemosynthetic ecosystems.
2 DISCIPLINE SUMMARIES
2.1 VOLCANOLOGY - Robert W. Embley and William W. Chadwick
Volcanology studies during NeMO'99 focused on, 1) continuing our instrumental monitoring efforts, 2) expanding our Imagenex sonar bathymetry of the 1998 eruption site, and 3) extending our mapping of the 1998 lava flow south to the area of the southern SeaBeam depth anomaly at 45 52' (confirmed as a new lava flow during dive R465 last year).
The extensometers that were recovered from Axial's north rift zone during NeMO'98 yielded an interesting data set. The instruments had been in place during the 1998 eruption and recorded a 4 cm contraction at the time of the eruption. This represents deflation of the entire summit area of Axial as magma intruded into the south rift zone, and is consistent with the rumbleometer instruments that recorded dramatic subsidence in Axial caldera. The extensometer and rumbleometer data can be modeled together to estimate the depth of the magma reservoir beneath the caldera and the volume of magma removed during the eruption/intrusion. These results were published in the December 1999 issue of Geophysical Research Letters. After the data was downloaded from the extensometers in 1998, they were re-deployed in the same area, and we recovered these again in 1999. Unfortunately, all 4 instruments failed during the 1999 deployment due to connector leaks and failure of components on the circuit boards. The status of these instruments for future deployments is currently being assessed.
The high-resolution bathymetry that can be collected with the Imagenex sonar was one of the highlights of NeMO'98. We were able to double the area of Imagenex coverage in 1999, mainly to the west of the area mapped in 1998. This helped define the western contact of the 1998 lava flow, and also showed many drain-out channels in the older lava to the west, suggesting that the previous eruptions from this area were more voluminous that the 1998 eruption. The Imagenex map fills a critical observational gap between multibeam bathymetry and bottom observations, and helps us understand what we see from ROPOS. It helps us map out the 1998 lava flow in unprecedented detail, including collapse areas and flow morphologies, puts the locations of vents sites and samples in a meaningful spatial context, and helps us interpret the sequence of events during the eruption. This is the first high-resolution map of a mid-ocean ridge eruption site and we will continue to expand the Imagenex coverage in future years.
During NeMO'98, our geologic mapping efforts were concentrated in the 3 km north of Marker 113. However, we know that the 1998 eruption extended at least 7 km south of Marker 113, so during NeMO'99, we extended this mapping to the south. Observations during dive R495 showed that even the large pillow mound that erupted at 45 52' was fed from a narrow fissure. Within a few hundred meters south of the pillow mound, 1998 lava can be seen filling, but not overflowing, a fissure that is 1-1.5 m wide. This extraordinary observation is essentially the surface outcrop of the 1998 dike that fed the eruption at this location, and the width of the fissure we saw is the minimum amount of seafloor spreading that occurred during this event. Between the pillow mound at 45 52' and Marker 113, the story is more complicated because there are other very young lava flows that are difficult to distinguish from the 1998 lava, except that locally they host clearly pre-1998 vent communities (mainly large, dead tubeworms). We were able to map out the distribution of lavas of at least 4 different ages during dives R492, R493, R494, R495, and R501. However, these dives only covered limited parts of this large area, and additional mapping will be necessary in future years to complete this mapping effort. In collaboration with M. Perfit and his students at the University of Florida, a careful collection of basalt samples was made during these mapping dives to determine if there are distinctive chemical differences between the 1998 lava flow and the surrounding older lavas. These results might help in the mapping effort and have implications for the evolution Axial's magmatic system.
The geologic results from this project also aid in putting into context the remarkable changes observed in the chemical and biologic systems at Axial Volcano since the 1998 eruption. The mapping provides the geologic context for the along-strike variations in the chemical and biologic characteristics of the hydrothermal system. For example, we were able to compare the general pattern of hydrothermal flow from the new eruption with that of the pre-eruptive system (mapped by previous camera tows and dives), suggesting that the conduit system was not dramatically changed by the dike injection and eruption. The north-south pattern appears to be similar, but there was apparently a small East-West displacement between the pre- and post-eruptive hydrothermal systems. The center of maximum hydrothermal flow appears to have remained in roughly the same place. This is also apparently where the maximum diversity in the microbial population is. The "snow blower" vents occur primarily at the northern portion of the system, where the lowest flow rates are located.
2.2 CHEMISTRY
2.2a Hydrothermal Fluid Sampling - David Butterfield
The main goals for fluid sampling for this cruise were 1) re-sample vent fluids from sites sampled last year and expand the sampling to cover a broader range of the eruption area in the SE caldera and rift zone, 2) re-sample diffuse, warm vents and hot vents in the ASHES field, and 3) sample vent fluids from CASM. The vent fluid studies are intended to use chemistry to understand the connections between volcanic activity, hydrothermal heat loss, and microbial activity in hydrothermal systems. Fluid chemistry is also an important measure of habitat conditions for studies of vent fauna colonization and species distribution.
Very few studies to date have focused intensively on the variation in diffuse fluid chemistry within a region. This work may yield new insights into the variability of sub-seafloor processes in a hydrothermal system.
Hot Fluid Sampler
We used the Hot Fluid Sampler (HFS) for the second year during this cruise, after several improvements were made over the proto-type model of last year. The sampler has a lower profile in front of the ROV so that visibility and ability to sample are not severely impaired. The plumbing layout was improved to allow more filters on the instrument. This year we were configured to take 6 piston samples (3 modified with high-vacuum valves for gas sampling), 8 collapsible bag samples with optional in-line filters, and 10 additional filters without water collection. One of the bag samplers was used as a flushing line for two titanium gas-tight samplers so that fluids of known temperature could be sampled by different types of samplers for comparison. On one dive, we can collect 10 discrete water samples for fluid chemistry, 5 water samples for gas analysis, and up to 17 filters for a variety of analytical purposes.
Several types of filters were used. Membrane filters of .45 or .2 micron pore size were used to collect particulate material for: xrf chemical analysis and SEM, particulate elemental sulfur, particulate organic carbon, lipids, and fluorescent in-situ hybridization (FISH) analysis. In addition, "Sterivex" high through-put cartridge filters were used to collect particles for DNA extraction. All of the analytical work done on the filters is designed to help us understand the chemical and microbiological variation among different types of vents. The in-situ filtration capability of the fluid sampler is an important advance over all previous vent fluid sampling instrumentation in that it allows us to concentrate particulate material from large volumes of water for multiple analyses at a given vent site, and it also allows us to separate the dissolved components from the particulate components at the time of venting, thereby eliminating uncertainty about post-sampling particle formation within the water sample containers. In many instances, we collect both filtered and unfiltered water from the same site for comparison. Overall, we have an excellent set of samples for fluid chemistry, gas chemistry, particle chemistry, and microbiology.
On-board fluid analysis:
Kevin Roe was the principal fluid analyst on this cruise, and carried out analysis for pH, alkalinity, hydrogen sulfide, dissolved silica, and ammonia. Most of our chemical analysis occurs on shore. We measured refractive index of the hotter vent fluids to estimate their salinity or chlorinity. Dave Butterfield analyzed particulate elemental sulfur by colorimetry on a subset of samples.
We were fortunate to have Andy Graham on board. Andy received cuts of most of the fluid samples for methane and hydrogen analysis by gas chromatography. In many cases, vent fluid samples arrived on deck containing a gas phase and a liquid phase. When this occurred we measured the volume of the liquid and gas portions and Andy analyzed both for gas content. In this way, the fluid sampler appears to be superior to the traditional titanium major samplers because it has much better gas retention capability, and the samplers are transparent, allowing us to separate the gas portion from the liquid. We cannot rule out some gas loss through the check valves, but comparison of the gas results from different samplers will help to evaluate this.
Initial results:
HFS was deployed on 2 short aborted dives and 3 complete dives in the 1998 eruption area, plus one complete dive at ASHES. HFS proved to be quite efficient. For example, on the first HFS dive, we had only 30 minutes of bottom time at marker 33 and took 5 samples (2 water chemistry, one gas chemistry, and two filters). For the entire cruise, we collected 43 vent fluid samples for water chemistry with HFS, 13 gas piston samples, and over 50 filters. In addition, titanium gas-tight samples were collected on many dives (see Leigh Evans report) and these will be analyzed for major element chemistry.
We have not yet processed the raw data from the last two dives, but the initial results appear similar to last year. Relative to the CoAxial eruption area, where there were large changes in composition and a decay in heat output one year after the eruption, we saw little change on the seafloor in the eruption area. Diffuse venting continued in many areas. The maximum measured temperature at marker 33 is higher than last year (78 versus 55 degrees). Looking at the ratio of hydrogen sulfide to silica (the ratio is only slightly sensitive to the amount of entrained seawater during sampling) it appears that the samples from throughout the eruption area this year are just slightly lower in sulfide relative to silica. Methane appears to be slightly higher this year than last year. We cannot say anything about the changes in salinity until we do high-precision analysis on shore.
2.2b OsmoSampler and OsmoAnalyzer Operations - Thomas Chapin
Changes in the chemical composition of hydrothermal effluent after a tectonic-volcanic event have been documented (e.g., Baker et al., 1987, 1998; Butterfield and Massoth, 1994; Von Damm et al, 1995; Massoth et al., 1995; Massoth et al., in press; Wheat et al., to be submitted) and a conceptual model has been developed that theorizes the chemical evolution of venting fluids (Butterfield et al., 1997). However, the timing of these changes is uncertain. To date observations of temporal variability in the chemical composition of hydrothermal fluids has relied on repeated submersible operations and the collection of discrete samples. While this technique provides some temporal constraints, a continuous water sampler or analyzer allows one to collect more samples with limited need for costly submersible operations. Our goal for this cruise was to deploy two short-term (two weeks) and two long-term (one year) continuous sampling systems to provide temporal constraints for observing hourly to daily and weekly to monthly chemical cycles in the hydrothermal effluent. Data from these samplers and their comparison to samples collected using traditional discrete sampling techniques will allow us to determine the temporal scale of chemical change in the hydrothermal effluent as the hydrothermal system evolves and may provide constraints for understanding the physical and chemical conditions at depth and the path for fluid circulation.
Two sampling systems were deployed, OsmoSamplers and OsmoAnalyzers. OsmoSamplers are continuous water samplers that use the osmotic pressure that is created across a semi-permeable membrane by solutions of differing salinity (Theeuwes and Yum, 1976; Jannasch et al., submitted). This pressure drives water across the membrane at a speed that is dependent on the surface area of the membrane, type of membrane, salt gradient, and temperature. An excess of salt is maintained on one side of the membrane, thus only temperature affects the flow of water in the sampler. Pumps in an OsmoSampler are used to continuously draw sample through a small bore (0.8 mm id) tubing that is attached to a 40-cm-long T-handle. An additional pump was used to add acid to the sample stream in most of the OsmoSamplers. A 1.5-m-long section of tubing separates the sample intake from the pump to allow the pump to be placed in an area void of hydrothermal influence and thus minimizes temperature (pump rate) fluctuations. A temperature recorder with a resolution of 0.0018°C is attached to the T-handle to monitor the same water that is being collected by the OsmoSampler. Chemical data are obtained by retrieving the sampler, cutting the sample tubing into sections, extracting the seawater, and analyzing the seawater for chemical species of interest. Time-stamps for individual samples are determined assuming a uniform temperature at the pump that translates into a uniform rate of pumping.
OsmoAnalyzers, in contrast to OsmoSamplers, use osmotic pumps to deliver reagents into a sample stream for in situ analysis (Jannasch et al 1994). An iron OsmoAnalyzer was deployed at Marker 33 to continuously measure Fe at 15-minute intervals over the next 6-9 months.
Two long-term acid addition OsmoSamplers, deployed from the NeMO 1998 September cruise were recovered on this cruise. These samplers, one at Marker 33 and one at Milky vent, continuously collected sample for 9 months providing 163 0.5-mL samples. Analysis for major elements and trace metals will be performed later in our laboratory. Milky vent started at 9.5 C but dropped to 3.6 C by the time the OsmoSampler was recovered. There was no visible floc venting from Milky and the low temperatures at the end of the deployment indicate that the diffuse vent had died out. Marker 33, on the other hand, continued to vent hydrothermal fluids up to 80 C and was quite vigorous. The NeMO-98 long term acid addition OsmoSamplers deployments appear to have been a success and will provide one of the first long-term continuous records of the chemical signature of hydrothermal fluids.
During NeMO-99, four long-term OsmoSamplers were deployed. Three OsmoSamplers were deployed at the Marker 33, in the hottest section with temperatures up to 80 C. The OsmoSamplers consisted of one regular acid addition, one bio-OsmoSampler which has a sodium azide biocide to prevent bacterial growth, and a long term Cu-OsmoSampler which will collect samples for gas analysis. Another long-term acid addition OsmoSampler was deployed in 70 C water at Magnesia vent, just north of Milky vent. Tremendous clouds of white flocculent material were coming out of Magnesia and it looked like a snowstorm.
A 2-week record high temperature record from the Hell vent was recovered. Unfortunately the deployment of a long-term acid addition OsmoSampler and temperature probe was not successful.

2.2c Gas Sampling - Lee Evans
The primary goal of gas sampling during the NeMO '99 expedition was direct sampling of vent fluids by way of Titanium Gastight bottles and modified pistons from the PMEL Hot Fluid Sampler (HFS). Approximately 30 useful samples were gathered and their available gas contents extracted and sealed in glass ampoules for chemical analysis. Analyses include helium isotopes, hydrogen and methane.
As with 1998's samples, the geographic coverage of sampling included the east side of the caldera along the region of the 1998 lava flow, Ashes vent field on the west side and Casm vent field to the north. Time series measurements will be possible at about 5 vent sites. The coverage of diffuse vent samples was extended southward on the east side in the direction of the vestige of the eruptive fissure.
This year's method modifications present a significant improvement as compared with those used to gather samples in 1998. At least some of 1998's collection were a bit more dilute than what is desirable. Both the plumbing scheme for titanium gastight bottles and the sample integrity of the gas piston samplers (HFS) were improved.
2.2d Studies of Dissolved Gases from Hydrothermal Vent Systems - Andy Graham
The main focus of our lab is the study of dissolved gases from hydrothermal vent systems. For this cruise I brought a gas chromatograph on board and analyzed fluid samples from the hot fluid sampler, suction sampler and a niskin bottle mounted on ROPOS. The main gases that I analyzed were dissolved hydrogen and dissolved methane. These gases are important in the hydrothermal vent community because certain microbes can oxidize these gases and use them as an energy source. Over 50 samples were analyzed ranging from 300 oC Inferno vent to 4 oC Magnesia vent. From an initial glance the data vent such as Marker 33 and Virgin Mound still appear to contain high concentrations of both hydrogen and methane. Further analysis and a comparison to last year's data will occur.
2.3 MICROBIOLOGY
2.3a Microbiological Sampling for Molecular Microbial Ecology Analysis
Western Washington University, Biology Department: Craig L. Moyer & Karen Lynch.
Introduction
One of the greatest challenges in microbial ecology is the accurate identification and description of microbial populations within their respective communities. This information is central to determining the extent of global microbial diversity, which remains the least understood of all the biological size classes. To address this challenge, molecular biological techniques using small-subunit ribosomal RNA (SSU rRNA) gene sequences have been applied to describe the structure and diversity of different microbial communities. The current endeavor is to examine specific habitats with known biogeochemical characteristics (e.g., S, Fe, Mn) to learn more about the dominant microorganisms residing therein. The focus of this study at Axial Volcano is to estimate the microbial community structure and diversity to assess the degree of commonality and uniqueness among local hydrothermal vent habitats, (i.e., vent-associated sediments, free-living microbial mats, microbes associated with subsurface floc-ejecta), and to also compare these results with distal hydrothermal vent habitats. This study will also allow for the enhanced development of a comprehensive global perspective regarding the diversity of deep-sea microbial communities.
Selective enrichment culture has severe limitations as an approach to the cultivation of naturally-occurring microorganisms. The majority (typically >90-99%) of microbes in nature have not yet been cultivated using traditional techniques. Consequently, it is very unlikely that collections of microbial isolates are representative of in situ diversity and community structure. Furthermore, because relatively nutrient-rich media are generally used for isolations, "weedy" or opportunistic microorganisms may be selected rather than those dominant in the natural community. The approach, herein, is to ascertain a microbial community's primary members through molecular (i.e., cell component) means and then to attempt to further characterize their respective phylogeny or natural history. Obtaining a better representation of microbial community structure and diversity is crucial to aspects of microbial ecology where Bacteria and Archaea interact with one another and with their environment, e.g., global biogeochemical cycling of matter, succession and disturbance responses, predator-prey relationships, and trophic-level interactions. These lessons can then be used to focus enrichment culture techniques towards ecologically significant taxa. This approach has been successfully used to isolate the dominant iron-oxidizer bacterial taxon found within the microbial community at hydrothermal systems located at Loihi Seamount, North Gorda Ridge, and other habitats (Emerson and Moyer, 1997; unpublished results).
Cell component analyses provide a culture-independent means of investigating microorganisms as they occur at hydrothermal vent systems (Moyer et al., 1994;1995; 1998). While several types of cell components have been analyzed, the SSU rRNA molecule offers an amount and type of information that makes it one of the best culture-independent descriptors or biomarkers of microorganisms. In recent years a detailed theory of evolutionary relationships among the domains Bacteria, Archaea and Eucarya has emerged from comparisons of SSU rRNA "signature" sequences. For example, each SSU rRNA gene contains highly conserved regions found among all living organisms as well as diagnostic variable regions unique to particular organisms or closely related groups. Additionally, each SSU rRNA gene contains about 1,500 nucleotides of sequence information that can be obtained and utilized to differentiate among closely-related and distantly-related groups of microorganisms. This type of molecular approach allows the autecology of microorganisms to be studied whether or not they can be been cultivated (Moyer et al., 1996). In addition, the phylogenetically described taxa or "phylotypes" can be placed in a synecology context through the examination of SSU rRNA clone libraries generated from a microbial community and habitat diversity can be analyzed through rarefaction (Moyer et al., 1998). These features make SSU rRNAs particularly useful for studies of molecular microbial ecology, where a broad and unknown range diversity of microorganisms is likely to exist. Currently, over 10,000 SSU rRNA sequences from both cultured isolates and environmental phylotypes have been made available for study through the Ribosomal Database Project at NSF's Center for Microbial Ecology at Michigan State University.
Experimental Design and Methods
Shipboard Processing and Storage of Samples
A dual approach was used for microbial sampling. First, a "slurp" gun suction device was be used in combination with a rotating rosette of sample bottles to "vacuum" and capture free-living microbial mats from the surface of various hydrothermal vent habitats. Slurp gun samples were successfully obtained from the East-Side of Axial at (1) Marker #33 Vent, (2) Markers N6 & N4 aka Cloud Vent, and (3) Magnesia aka Whiteout Vent. We also began to investigate the phenomena of the "bag creature" this year with slurp samples collected on the East side of Axial at both Axial Gardens (Marker #113) and from a new site entitled Joystick Vent (Marker #42). This is a characteristic jelly-like residue, which looks to be composed of complex polysaccharide globules that form in and around low temperature diffuse flowing vents in conjunction with microbial mats. No suction samples used for microbiology were obtained from the vicinity of the ASHES vent area this year.
Second, the deployment and recovery of microbial traps using glass wool as a substrate for microbial growth. Microbial traps were constructed using a cluster of three 3" sections of 4"o.d. plexiglass tubing, surrounded top and bottom by a 202 µm nylon mesh (Nytex) to exclude macrofauna and meiofauna grazing. These were placed directly into diffuse vents and were used to collect colonizing microorganisms in an effort to examine community succession. These were deployed with the idea of attempting a time-series with both short-term (days) and long-term (annual) time scales. This objective was successfully achieved with long-term recoveries from last year's NeMO98 made at both Marker #33 and Cloud Vent (Marker N4), short-term recoveries from deployments made this year were also made at Marker #33, and Cloud Vent (Marker N4) on the East-side of Axial Volcano. New long-term deployments again were made at both of these two East-side sites. Unfortunately, only a single successful recovery from the ASHES Vent Field was made. This occurred at Gollum Vent, where two long-term deployed microbial traps were heroically recovered (in spite of the onset of foul weather conditions) and a fresh trap was deployed. Short-term recoveries from the ASHES area remains illusive, but may again be attempted next year, in addition to attempting continued long-term recoveries from each of the following locations where microbial traps have been previously deployed: Gollum, ROPOS, Hillock, Mushroom Vents.
Microbial samples collected were each independently processed. Microbial biomass preservation was achieved by quick-freezing in liquid nitrogen and storing on dry ice until return to the laboratory. These samples will be used for the direct extraction of nucleic acids. A series of sub-samples were also (i) cryo-preserved (again using liquid nitrogen quick-freezing) with 40% glycerol, and (ii) aliquots were stored at 4C, both for enrichment culture selection. Another series of sub-samples was fixed with 2.5% EM grade glutaraldehyde for examination with SEM and epifluorescence microscopy.
Laboratory Processing and Molecular Biological Analysis
Initially, all samples will be examined by epifluorescence microscopy in an effort to ascertain biomass estimates and examine morphological diversity. A subset of these will also be examined through SEM and an analysis of extractable lipids, which provides an estimate of microbial biomass and initial clues into community structure. The overall molecular biological strategy used will be essentially that of Moyer et al. (1994, 1995; 1998) with a few technical and logistical improvements. The first step will be the efficient and direct extraction of high molecular weight nucleic acids from quick-frozen samples. This will be followed by PCR amplification of SSU rDNAs using previously defined conditions to maximize the equal representation from each population contained within a respective community. The concept is to proportionally amplify or make several copies using the total genomic DNA from a natural community serving as the template for oligonucleotide primers that are complementary to universally conserved SSU rDNA sequence positions. Representative SSU rDNA amplification products are cloned generating a clone library. Clone libraries will then examined through the use of Amplified Ribosomal DNA Restriction Analysis or ARDRA and by using rarefaction as a metric for organismal diversity (Moyer et al., 1998). This approach, using tetrameric restriction enzymes, has been shown to detect >99% of the taxa (i.e., phylotypes) present within a model dataset with maximized diversity (Moyer et al., 1996). SSU rDNA sequences will also be subjected to phylogenetic analysis (using distance matrix and maximum likelihood algorithms) to estimate the affiliated ancestral lineage for each dominant community member thereby yielding clues as to their respective evolutionary history and potential physiology.

2.3b Hydrothermal Fluid Microbiology - Julie Huber and Sheryl BoltonWe returned to sea this summer to continue our research on microbial communities in diffuse fluids on Axial Seamount. Along with Dave Butterfield, we are trying to quantify the diversity of microbes and their metabolisms in relation to the chemistry of the diffuse fluids over time.
We have successfully cultured mesophiles, thermophiles, and hyperthermophiles from all diffuse fluids collected during this cruise. We have over 100 positive enrichments (which require confirmation on land) at temperatures ranging from 23 °C to 110 °C in a wide variety of media, mostly anaerobic. One very exciting find was the culturing of a microbe at 110 °C from Marker 33. This hyperthermophile (or group of hyperthermophiles) was successfully transferred six times while at sea. Currently, the highest known upper temperature limit for growth of a living organism is 113 °C by a sulfur-dependent hyperthermophilic Archaea called Pyrolobus. Our microbe, growing anaerobically with elemental sulfur, was isolated from ~70 °C fluid at Marker 33. We also found that it is producing large amounts of hydrogen and some carbon dioxide, as analyzed on the gas chromatograph by Andy Graham. The fact that we have found a microbe (or group of microbes) growing at such a high temperature, yet isolated from fluids much below its temperature of growth, strongly suggests that there is a hotter subsurface environment that these microorganisms are growing and thriving in. By studying this exciting microbe, we hope to learn more about the metabolic wonders of life at high temperature and the limits on life.
Additionally, quantitative enrichments (MPNs, Most-Probable-Number technique) were performed at a variety of temperatures from several sites. The table below contains the 95% confidence interval for the abundance of microorganisms that grow in the given media, given in microbes/liter. These data are preliminary and must be confirmed by microscopy on land.

We also obtained a number of discrete filtered fluid samples for molecular analysis using the hot fluid sampler. These filtered samples will be used in total community DNA analysis to determine microbial diversity and phylogeny, FISH (Fluorescence In-Situ Hybridization) to quantify and track certain microbes, and lipid analysis to quantify and determine the physiological state of microbes. We will also perform epifluorescent counts on all preserved fluid samples for microbial enumeration.
This combination of culturing, microscopic, and molecular techniques will help us determine how any changes in the fluid chemistry over the past year may be reflected in the microbial community structure. Additionally, we will continue to explore the microbial ecology of new diffuse sites and high temperature microbes found here at Axial Seamount.
2.3c Microbial Food Webs - UQAM Disciplinary Summary, Kim Juniper
Emphasis this year was placed on the consolidation and expansion of a study of the dynamics of microbial food webs. The overall goal of the study is to understand how the structure of vent food webs add structure and complexity as new vents and vent fields are colonized by increasing numbers of species. Particularly relevant are questions of the importance of vestimentiferan tube worms as a keystone species that create habitat for other organisms, and the relative importance of free-living and symbiotic microbial production as food sources for animals. Suites of faunal samples were collected from new vents in the East Rift Zone as well as from mature and senescent vent sites on adjacent older lava flows. Tissue samples from these organisms will be analyzed for stable carbon and nitrogen isotopes and for lipid biomarkers. Samples of microbial mat, biofilms and particulate organic material collected from each site will be similarly analyzed to permit matching of deposit and suspension feeding animals to their food sources, as well as the identification of trophic levels. The microbial and particulate samples will also be analyzed for ATP and total lipid content, as estimates of microbial biomass available for consumer organisms. Samples were also preserved for a molecular study of the diversity of microorganisms that constitute the animal food supply.
Samples collected came almost entirely from basalt-hosted diffuse vents, with the exception of samples from T&S vent at CASM and 2 collections from the sulfide worm habitat at ASHES. Planned collections of sulfide edifice tube worm communities in the ASHES field were missed because of the weather-related early termination of the dive program.
A vent-field scale study of the development of food webs was initiated at the Cloud site in the East Rift Zone. This study will examine spatial relationships between geological features, the location and intensity of venting and the colonization of individual vents, much as we have previously done for sulfide edifices. This is very much a mapping based project that seeks to discover spatial and temporal patterns that lead to the development of testable hypotheses. Video imagery and photographs collected during two dives are being used to develop a map of the distribution of individual organisms in relation to geological features and venting. This map will be incorporated into a small-scale GIS later this summer, to facilitate quantification of organism distribution and habitat. A short Imagenex survey was also perform during the video transects. We will attempt to integrate the resulting data into the map, despite problems with imprecision of navigation along and between transects. Mapping will be repeated in subsequent years to document changes in venting and community composition.
2.4 MACROBIOLOGY
2.4a Biology of Low Temperature Sites - Maia Tsurumi and Jean Marcus
1. Introduction
This biology program focused on two major themes: 1. succession (continued colonization through senescence) of the South Rift Zone vents, and 2. The regional distribution of species and populations of Axial Seamount. An important aspect of our sampling is to couple our collections with vent fluid chemistry. We were very successful with this approach last year, and during NeMO 1999 we were fortunate to extend this coordinated sampling. Of all our samples, there were only three which had no chemistry data.
2. Succession
a) Continued colonization.
We were intrigued last year to find three types of initial colonization at new vents on the new lava. These included: i) Small vestimentiferan recruits with three or four other known species, ii) Dense snails and iii) A mix of scale worm species and other polychaetes. This year we anticipated more homogeneous communities with tube worm recruits at all new vents. This prediction mostly held true. Tube worms occurred at all vents with the exception of the northern area where venting may have subsided, based on the general lack of vent fauna. For example, we found no fauna at Milky vent, although it supported scale worms and other polychaetes last year. Although tube worms were present and of a morphotype typical of new venting, they were not found in the abundance that we anticipated. In fact, this scarcity of tube worms forced us to suction sample at many locations because grabs were not possible.
We were able to repeat sample at all locations where we had samples last year. Further, we were able to sample two new vents on the southern portion of the South Rift Zone. This sampling revealed a species of nemertean worm seen after the 1993 CoAxial eruption, but not observed on the Axial 1998 flow last year. Although the lava in this area is of uncertain age, the tube worm morphology indicates that this is new venting. Preliminary sorting of samples shows that new species have continued the colonization sequence. There also is an observed shift in the relative abundance and biomass of some of the species. Next year should be interesting...
b) Senescence
Since venting is ephemeral, we have the opportunity to see what the vent community looks like at all stages of its "lifecycle". This is next to impossible to do in many other ecosystems because of the time scales involved. Until recently, studies of vent succession have focused on the initial and intermediate stages of the communities. For the last couple of years our lab has been working on understanding the entire sequence of succession from initiation to death. This requires opportunistic sampling of dying or dead vents. We obtained video, a suction sample, and one tube worm grab at a senescent vent and anticipate that this will help us to sort out the final sequence of the vent cycle.
3. Regional Character
Axial Volcano is one of the few places on the Ridge that allows us to study discrete, well-separated communities. A current question in vent ecology is how populations interchange among sites. We are working on better describing species distributions in a regional setting. Some vent species are very patchy and we are attempting to understand in an ecological framework why this is. To understand vent community dynamics within the caldera, it is crucial to sample as many intra- and inter-vent field assemblages as possible. To this end, we re-sampled, CASM and most of the South Rift Zone (North and South). In addition, we have selected one species of polychaete for a population genetics study.
4. A Final Comment
We would like to thank the NeMO 1999 science party for their encouragement, help, and interest. Also a big thank you to all the crew of the Thomas G. Thompson and the C.S.S.F. ROPOS gang.

2.5 HYDROTHERMAL DEPOSITS - Steve Scott
There are two types of hydrothermal deposits in the caldera of Axial Volcano: Fe-oxyhydroxides and sulfide-sulfate. Both were investigated and sampled during NeMO 99.
Fe-oxyhydroxide deposits
Analyses of Fe-oxyhydroxide samples taken from Steve Mound, Gollum Vent and south of ASHES in 1998 show the material to be silica poor ferrihydrite (nominally Fe5HO8.4H2O) together with amorphous silica. Ferrihydrite is commonly found in soils, oxidized mine wastes and other iron-rich environments, and now also on the deep seafloor (Boyd and Scott, 1999, Can. Mineralog.). The material is essentially amorphous although it can have short-range crystallographic order. It is of biogenic origin, clearly coating bacteria as seen in SEM and STEM images.
During NeMO 99, ferrihydrite deposits were sampled at Oxide Vent (inactive); at Naaz, south of ASHES (inactive); and, at the west wall of the caldera near ASHES (active). Red iron oxides and bacterial fluff were also observed at a few other places, most notably on the new lava in the south rift zone. The Naaz site is a new discovery of clusters of 10-15 cm diameter x 20-60 cm high conical structures that look like termite mounds made of ferrihydrite and of anhydrite coated by ferrihydrite. Naaz covers an area of about 5m (east-west) x 15m (north-south) and lies about 5 m south of Crack Vent. The distribution of the mounds within a cluster and in the peripheral regions where mounds are widely dispersed appears to be controlled by fractures in the otherwise relatively smooth sheet flow surface. Both vent fluids (6oC maximum temperature) and consanguineous oxide-coated bacteria were sampled at the west caldera wall. This will enable a determination of partitioning of elements between fluid and solids, an important step in the study of this biomineralization process.
Sulfide-sulfate spires
The CASM T & S spires, discovered during the 1998 NeMO expedition, were sampled. The five samples include different mineralogical types and both actively venting and inactive areas. A short distance north of T & S, on the east wall of the CASM rift, there is a large pile of oxidizing sulfide talus whose source was not thoroughly investigated. There is also evidence (red staining) of hydrothermal activity in some of the talus blocks at the foot of the north wall of the caldera. One sample each from Castle and Flat Top were lost. The Castle sample, taken from the top of the structure, appeared to be oxidized.
Two recovered HOBOs (Hell Vent and CASM T & S Vent) had ~1 mm thick sulfide deposits on their probe sheath. By determining the mass of precipitated material/ unit area/time the HOBO was deployed, the precipitation rate can be calculated, assuming it is linear with time. Furthermore, this rate can be known as a function of fluid chemisty (the vent fluids were sampled) and temperature (from the HOBO record).
Suction sampling within the Marker 33 vent revealed the presence of sulfides (pyrite + ?chalcopyrite) and anhydrite coating a cm-size piece of basalt and impregnating the basalt=s vesicles. The anhydrite and possible chalcopyrite indicate much higher temperatures than are now observed at Marker 33. It is postulated that the vent system was much hotter just after the January 1998 eruption than it is now.
2.6 ROCK SAMPLING AND PETROLOGIC STUDIES - M. Perfit and J. Chadwick
Introduction:
The objectives of the rock sampling program were four-fold: 1. complete detailed sampling and mapping of the 1998 lava flow to aid in the identification of its boundaries and extent, 2. determine the compositional and petrologic heterogeneity of the 1998 flow and spatial variability, 3. compare the composition of the 1998 flow to that of the surrounding older flows to evaluate temporal changes in magma source, 4. recover samples from Axial's north and south rift zones by rock corer to investigate temporal and spatial variations in magma genesis on a regional scale.
The initial sampling and subsequent chemical analyses of basalts from the 1998 flow showed that it was very similar in composition to basalts previously recovered from the caldera. In particular, the 1998 flow has a composition like that of young looking flows from the CASM site. All are normal mid-ocean ridge basalts (N-MORB) that have slightly elevated K2O contents (and other incompatible trace elements) compared to other MORB from the Juan de Fuca Ridge. Of a total of 16 samples analyzed from the 1998 flow, fourteen have nearly identical compositions; two from the southernmost part of the flow (Recovered on dive R465) are slightly more evolved. This suggests some chemical differentiation may have occurred during the diking event or that the magma source is chemically heterogeneous.
The detailed sampling completed this year will allow us to place more rigorous constraints on the chemical composition (and variability) of the 1998 flow as well as to determine the composition of older flows in contact with the new flow. Assuming there are significant compositional differences between the 1998 flow and surrounding older flows, we plan to use the geochemical data in conjunction with the observational data and mapping efforts to generate a geological map of the 1998 flow. In addition, comparison of the major and trace element composition of the new flow to older flows can constraints on magma chamber temperature changes and magmatic evolution. Measurement of U-series isotopes (by K. Rubin) will provide information about the age the magma chamber for the different flow units in the Caldera and possibly allow us to relate young flows from CASM and ASHES to the 1998 flow.
From a regional standpoint, the 1998 flow is very important because it provides us with another 'zero age' flow from the JdF to use in comparing an contrasting the current sources and melting parameters along the ridge. Initial analyses of the 1998 flow confirm that the source of Axial magmas is slightly more enriched than the mantle source of southern JdF lavas and quite a bit more enriched compared the source for CoAxial Segment magmas. This years 55 rock cores now gives us more than 115 rock core localities along Axial's north and south rift zones. These samples, together with the samples recovered in the caldera, will be used to investigate the spatial and temporal variability of magma genesis at the entire volcanic edifice that has been created by the interaction of Axial melt anomaly and the Jdf ridge.
ROPOS Operations
During this cruise, we recovered 52 samples from ROPOS dives. Many of these samples were 'opportunistic' in that they were recovered during biological grabs or suction samples for fluids or biology. Most of these consisted of glass chips and were primarily from well documented vent sites within the 1998 flow. In order to facilitate recovery of very glassy samples which can be nearly impossible to grab with ROPOS manipulators, we developed small rock wax corers that were deployed on ROPOS for the first time. These 'chapstick' cores were quite effective in sampling the glassy surfaces of lavas and proved to be a quick, easy way to get additional rock samples. Deployed rock cores were placed into a small mesh bag ('purse') fashioned to attach to the front of the bioboxes or fluid sampler. This bag was also used to recover temperature probes and additional rock samples. The glassy crusts from all large 'whole rock' lava samples were sub-sampled to be hand-carried with core samples. The highlight of the rock sampling came during the biogeology dive R501 during which two E-W traverses were made across the 98 flow while detailed volcanological and geological observations were made. During the dive a record total of 16 rock samples were recovered using the manipulators, rock cores and suction sampler. Precisely located samples at lava flow contacts should aid us in distinguishing flow units.
Rock Coring Operations:
Rock coring during the NeMO 1999 cruise continues the effort begun during NeMO 1998, when 49 successful rock core attempts were made. An additional 61 core samples were collected this year, for a total of 109 for the two cruises. Samples were collected principally in the south rift zone of Axial Seamount (48 samples), from just off the flank of the seamount south to approximately 45 degrees 39 minutes latitude. The remainder of the samples were collected along the Vance segment of the Juan de Fuca Ridge (3 samples), the southwest rift zone (4 samples), and the north rift zone (6 samples). The glass from this effort will be analyzed for major elements using electron microprobe and for trace elements using laser ablation inductively coupled plasma mass spectrometry (ICPMS) and X-ray fluorescence (XRF) techniques. It is hoped this study will lead to a better understanding of the relationships between the seamount, rift zones, and Juan de Fuca ridge, as well as insight into the magmatic, volcanic, and tectonic processes that have created the rift zones.
Rock coring activities took place in periods between ROPOS dives, and were undertaken on the CTD wire on the starboard side of the ship. The corer has 7 wax-tipped cups which collect small shards of basaltic glass from the ocean floor. The corer was sent down on the wire at approximately 60 meters/min. until the winch monitor tension dropped considerably, indicating contact with the floor. An additional 5-10 meters of wire was spooled out prior to reversal of the winch and retrieval of the corer, again at 60 meters/min, after a short period of slow (10 meters/min) retrieval to get the corer off the bottom. This method resulted in a successful retrieval of ocean floor materials in all attempts, although no glass was collected in 2 attempts (sediments only).
3 Non-ROPOS OPERATIONS
3.1 Mooring Deployments /CTD's /XRF Analysis - Jim Gendron
Early in the cruise, one CTD cast was completed South-East of the venting area on the new lava. The water was collected around 1300 meters as a non-plume background sample for many of the groups onboard.
During the cruise, the hot fluid sampler was used to collect 22 filters for XRF analysis. These samples will be analyzed when we return to Seattle. Also collected on the fluid sampler were about 30 samples for SEM and 5 samples for Particulate Organic Carbon (POC). A total of four, good Niskin samples were collected, one each over Castle, Magnesia, Cloud and CASM vents. Another was attempted over Hell vent, but it appears to have pre-tripped sometime during the dive.
Near the end of the cruise, three MTR moorings were deployed. One was at ASHES and two were close to the new lava vent area.

3.2 NeMO'99 Website and Public Outreach - Nicole Nasby, Greg Pillette, Andra Bobbitt http://www.pmel.noaa.gov/eoi/nemo/
The goal was to create an educational web site that would be for use by students and teachers, primarily at the secondary level. The web site offered daily updates on the cruise and allowed interested individuals to follow the progress of the scientific expedition at Axial Volcano. The site was set up to provide daily updates that included a scientific report on the latest activity. There was also a weekly science summary written by the Chief Scientist. The web site included a daily personal perspective section that highlighted an individual from the scientific party of ship's crew, and a daily log written by the "teacher at sea" Greg Pillette. The last component was an interactive question and answer section so that the public could interact directly with the scientific staff.
Each of these sections was coordinated by Nicole Nasby and relevant digital images were included. They were sent from the ship to HMSC and were added to the web site on a daily bases by Andra Bobbitt in Newport. This material was then presented to the general public at HMSC, each day, by the teacher on shore, Steve Babcock. Feedback and question from the public were sent to the ship to be answered by the scientific staff.
We have received positive feedback from the web site maintained this year as well as the one from NeMO '98. We have heard from teachers who have used last year's site in a classroom situation. Unfortunately classes are not in session at this time, so there is little feedback from teachers and students on the NeMO '99 site at this point, but we did get several questions posted to the web site indicating a positive reaction. As with last year, many of these questions were from family members of science and ROPOS personal.
4 NAVIGATION
4.1 Navigation Overview - Susan Merle and Bill Chadwick
All ROPOS dives were navigated using long-baseline transponder nets with the Seascape navigation software. The navigation computer had three main inputs into Seascape to aid in ROPOS navigation: P-code GPS from the R/V Thomas Thompson, ROV depth data provided by the ROPOS sensor and the PS8000 data from the range meter. Transponders were already in place for the ASHES net and the North Rift Zone (NRZ) net. Deployed last year during NeMO'98, the expendable transponders should have five year lifetimes. The transponders for those two nets only needed to be enabled. A third net, on the South Rift Zone (SRZ), was added with three recoverable transponders. Unfortunately, due to hardware problems with the NOAA PS-8000, the calibration of the SRZ Net was poor and this net was only marginally useful.
Once the cage reached its final depth and ROPOS drove to the seafloor, the cage depth was manually entered into the Seascape program and was held constant, unless the wire out for the cage changed during the dive. The range meter was attached to the top of the cage, was hard-wired to the hydro lab and triggered by Seascape on the navigation computer. Cage and ROV fixes were generally scattered with RMS errors of about 30 meters. Navigation fixes are recorded in latitude/longitude and UTM x/y (in meters) in the log files and were processed by Susan Merle in the IDL programs navedit2 and navedit3 (written by Bill Chadwick).
In 1999 navigation was somewhat less reliable than in 1998. During several dives the 11.0 transponder in the ASHES net was accidentally disabled and this caused the 1999 navigation fixes to be shifted to the west or south of the 1998. Since '98 navigation was more robust, no old vent or marker positions were changed, even if the '99 positions did not agree with those of '98. After the '99 cruise a few of the mysterious navigation problems we had were identified. The NOAA PS-8000 on El Guapo was determined to have a bad microprocessor, which created problems with the SRZ net calibration. Another mystery solved concerned the fact that it seemed that transponder 11.0 in the ASHES net would shut itself off. It was discovered on Bill Chadwick's Cleft cruise in September '99 that the 11.0 had a disable code of C, not B like all the other transponders. This would not have been a problem, if the ROPOS transponder we tried to use, unsuccessfully, had not had an enable code of C. So, we would try to enable the ROPOS transponder, unwittingly disabling the 11.0 transponder in the ASHES net.
The dive plots will be a useful guide to determine navigation gaps, bad navigation, etc. When acoustic nav was not available GPS ship nav was used. Plotted positions are for the reference point, about 37 meters forward of the stern at the GPS antennae.

5.5 Dive Map Nomenclature
The dive maps depict all Vents and Markers visited, samples collected on each dive, in addition all instruments deployed and recovered are also cited.
Nomenclature Example: SS-12_dfl_R503-4
The first letters indicate the sample type. The sample type may be followed by a hyphen and a number, which indicates the number for that specific sample type (could be a HFS filter number, suction sample jar number, etc.)
The letters following the underscore give more information about the sample:
_dlf indicates that the sample was in diffuse flow.
The final number, following the hyphen, designates the dive sample number.
-4 indicates that it was sample number 4 for the dive.
Sample type abbreviations More sample information:

5.6 ROPOS Dive Logs, Dives R483 - R502
Dive R483 | |||||||
Dive Plan: High resolution survey of Mkr-33 using the Sit camera and Imagenex. Elevator will be used to gather experiments from Mkr-33. Suction sampling will be done there and at other active vents to the north. | |||||||
Time-lapse camera will be brought up in the arm of ROPOS. | |||||||
ROPOS Configuration: Biobox, Slurp Sampler, Gas Tights, Imagenex, and the other cameras. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

END OF DIVE R484 |
|
Summary of Dive R484: For about the first half hour of the dive the log entry program was shut down. During the collection of the first suction sample it was rebooted. | |||||||
Mkr-33: SS of mat; one nearly whole crab captured, TLC recovered, deployed bactraps. Cloud: Two bactraps and one MTR recovered, deployed bactraps, short worm survey. | |||||||
Suction sampler clogged on first sample. Color balance on frame grabs was poor. The sub lost hydraulic fluid which forced the end of |
Dive R485 | |||||||
Dive Objectives: Primary objective of the dive is to obtain vent fluids/filtered samples along eruptive line. Dive will begin at Mkr-33 and end at the Milky Vent area. Suction samples will also be done at some of the sites. | |||||||
Elevator will be recovered (weather permitting) sometime during the dive. | |||||||
ROPOS Configuration: Vent Fluid Sampler, Suction Sampler, Gas Tights, Imagenex, and cameras. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

Dive Summary for R485:
ROPOS was in the water at 0706, 25 June 9. When the cage reached 1315m it was determined that ROPOS was still tied to the cage by a rope. ROPOS returned to the surface and the rope was removed. Dive was restarted at 0936. |
|||||||
ROPOS reached the bottom at 1053 and Mkr-33 was located at 1100. The sampling probe for the fluid sampler was positioned in the crack, based on the highest temperature measurement. This also appeared to be the area of highest flow. | |||||||
Five HFS samples were collected. At 1148 the sub was shut down due to a loss of hydraulic oil. ROPOS returned to the surface, after some difficulty getting the sub back into the cage. |
Dive R486 | |||||||
Dive objectives: Continue the dive plan from dive R485. More fluid sampling, slurp sampling, reposition bacterial traps, recover animals. Imagenex survey at end of dive. | |||||||
ROPOS configuration: Vent fluid sampler, Slurp sampler, gas tights, Imagenex, cameras. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

Dive R487 | |||||||
Dive Plan: Same as for R485 and R486. Primary objective is to obtain vent fluids/filtered samples along eruptive line. Will begin at Mkr-33 and end at Milky Vent area. Suction sampling will also be done at some of these sites. | |||||||
Elevator wil be recovered (weather permitting) sometime during the dive. | |||||||

8 | 17 | 1523 | 91 | 423718 | 5087582 | Sheet flows sort of like broken up shelf steps, covered in orangey iron rich sediment/bacterial goop. Looks primarily inorganic. | |
8 | 19 | 1523 | 354 | 423846 | 5087122 | We can see some more venting in a crack here - looking for Snail still, but we are investigating this crack with diffuse flow coming out. There are lots of gastropods and tube worms. | |

Dive Summary: We started at Mkr-33 and took filter samples,
fluid samples, slurp samples, and one Ti gas-tight sampler. We then moved to Snail and Marcus took a slurp sample. |
|||||||
We also took temperature measurements at Snail with the HFS and got a Tmax = 13. We then moved to Cloud, Mkr-N4 and Mkr-N6 where Ti gas-tight, gas piston, regular piston, bag samples and filtered slurp samples were taken. | |||||||
Bag samples were then taken at Nascent and MiniSnow Vents. At Mkr-N3 bag, filter, piston and gas piston samples were taken. Bag samples were then taken at Milky and Ouzo Vents. | |||||||
We then came upon Whiteout Vent, a previously unnoticed area and took a gas piston, filters for DNA, POC, sulfur and lipids, piston and bag samples. The remainder of the dive was an Imagenex survey, until oil pressure was lost and the dive aborted. | |||||||
Notice: Due to the nav offset, as not all transponders were working, it was later determined that "Whiteout Vent" is actually Magnesia Vent discovered in '98. Much more active in '99. |
Dive R489 | |||||||
Dive Plan: Suction sampling - Cloud for Moyer, Mkr-33 for Levesque, Mkr-N41 for Scott/Juniper, Nascent for Levesque/Marcus/Tunnicliffe, Whiteout for Moyer/Juniper, Oxide samples for Scott/Juniper (in flushing bottle). | |||||||
BioBox collections - Mkr-N41, Nascent, Old Flow, OldWorms, and for traps if previous collections are successful. Imagenex survey of western part of lava flow. Recovery/deployments of MTR/Vemcos, osmos and traps. Collect basalt samples, recover elevator. | |||||||

18 | 1 | 1522 | 68 | 423879 | 5087069 | Starting at N4 we are going to survey all of Cloud with video, 35 mm still camera (mounted vertically) and imagenex from a depth of 1521m. We are going to take overlapping photos and since there is a 5 sec. lag between each photo, the pace will be slow. | |
18 | 6 | 1522 | 78 | 423893 | 5087117 | Lift off! Camera survey starting. Heading east. | 3 photos |
18 | 8 | 1523 | 93 | 423898 | 5087117 | Aborting survey because we stirred up to much debris in the water column. Starting again. | |
18 | 11 | 1522 | 86 | 423906 | 5087135 | Back at Mkr N4, positioning to start survey again. | |
18 | 20 | 1522 | 105 | 423775 | 5086584 | Attempt #2 - starting survey from Mkr-N4 at a heading of 105 degrees for approximately 6.5 m to Mkr-N6. | |
18 | 22 | 1522 | 104 | 423880 | 5087070 | Photo survey. Imagenex head is about 2.5-3 m of the bottom. | 5 photos |

22 | 24 | 405 | 289 | 423645 | 5085308 | Dive Summary: Dive R492 was a geology reconnaissance dive of the '98 lava flow on the SRZ, south of the area surveyed in '98. The eastern and western limits of the '98 flow were surveyed, and several targets were added to aid in improving the lava flow | |
outline. Biological and suction samples were taken, as well as many rock samples. A large ventfield was discovered on the east side of the '98 flow in older lava. The vent was named Coquille. Dying Vent was not seen, but Bag City Vent was discovered. |
Dive R493 | |||||||
Dive Plan: Dive R493 is an extension of Dive R492, which was halted to recover the elevator. Again the objective is to map the 1998 lave flow from the caldera down to 45deg 52min North. | |||||||
The earthquake swarms extended south to that location but the only seafloor information is from Dive R465 ('98), which mapped a lava flow at the site of the SeaBeam anomaly at 45deg 52min North. | |||||||
Vents discovered along the way will be sampled. On Dive R492 new vents were discovered at the western edge of the contact between old and new lavas. | |||||||
ROPOS Configuration :Suction Sampler, 5 and 7 function arms with claws, cameras, and BioBox | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

7 | 34 | 1722 | 9 | 421811 | 5080068 | We've come up about 5 m- degrees with SeaBeam data | |
7 | 35 | 1720 | 4 | 423246 | 5079378 | Lobate flows - some hydrothermal staining. Can see some holes where flow was coming through. | |

7 | 47 | 1720 | 15 | 422207 | 5079951 | Looks like we're in this east-west running channel, curtain draped lava flows. | Photo-106 |
7 | 50 | 1720 | 10 | 422206 | 5079975 | Brittle stars- looks like it's flattening out again. | |

7 | 53 | 1720 | 14 | 422212 | 5080056 | These little wormy things are moving very fast- what are they? They're doing the scale worm dance. They're really pale because they're malnutritioned. | |
7 | 54 | 1720 | 10 | 422213 | 5080075 | On the edge of something- a big deep hole- porthole to the subsurface. A big collapse about 5 m deep. Photos 108 and 109 | Photos |

7 | 55 | 1719 | 11 | 422208 | 5080097 | Looks sort of post-eruptive. | |
7 | 56 | 1719 | 18 | 422208 | 5080097 | This is a pretty chaotic collapse - looking north to find the edge of it. Looks tectonic-structural trend. | |
7 | 57 | 1720 | 12 | 422208 | 5080097 | Floor is covered with jumbled pahoehoe lavas. | |
7 | 57 | 1718 | 10 | 422196 | 5080116 | We can see the other side of this feature - approximately 40 m wide. It's not a sheet flow. | Photo-10 |

8 | 38 | 1717 | 248 | 422291 | 5080340 | Moving ship 20 m to bearing 25 - around northern end of SeaBeam anomaly lava flow. Still unclear if an eruptive fissure extends to the north from here. Trying to find out by going west first, then will go northeast. | |
8 | 45 | 1719 | 216 | 422291 | 5080340 | Still looking at the contact-great contrast between old and new. | |

9 | 5 | 1720 | 275 | 422291 | 5080340 | We haven't found any evidence of a northward fissure along this east-west contact. Looks like the contact is trending southerly. | |
9 | 8 | 1720 | 274 | 422291 | 5080340 | Going back to the cage for tether management. | |
9 | 10 | 1696 | 94 | 422291 | 5080340 | Back in the cage, now we're heading back to the bottom. | |
9 | 11 | 1717 | 37 | 422291 | 5080340 | Now we're just going to follow the contact, but right now we're in the new lava. Heading north to look for the contact. | |
9 | 12 | 1720 | 2 | 422291 | 5080340 | We're at the contact again. Starfish on the old lava. Heading west. | |

9 | 42 | 1713 | 343 | 422291 | 5080340 | Older lavas turning more to pillows - still about the same age, though. | |
9 | 45 | 1713 | 356 | 422291 | 5080340 | Looks like we see some of the glass fragments again on the old lavas. Hmmm. curious. | |
9 | 47 | 1712 | 356 | 422291 | 5080340 | Still seeing those little pieces of glass on the old pillows and in the sediment pockets. Must be something new nearby. | |
9 | 49 | 1710 | 355 | 422291 | 5080340 | Looks like there are even more little pieces of glass on the old flow now. | |

18 | 36 | 1528 | 20 | 422709 | 5083710 | Dive Summary: ROPOS Dive R494 was a continuation of the two previous dives, which were ended early. | |
The objective was to determine if the 1998 eruption was continuous between the northern, well-mapped area and the southern SeaBeam anomaly (visited last year on R465), and to map out the extent of the 1998 lavas. | |||||||
This dive started about 800 meters south of the southern SeaBeam anomaly (1200 m south of the R465 dive track) on Axial's South Rift | |||||||
The pre-1998 lavas were much older here, in general, than further north (near Bag City Vent), allowing the 1998 lavas to be easily distinguished. About 500 meters south of the southern SeaBeam anomaly ROPOS encountered a fissure with '98 lavas in the | |||||||
bottom. As ROPOS approached the anomaly, the lavas overflowed the fissure and spread outward. This was clearly the surface expression of the dike that fed the eruption. North of the southern SeaBeam | |||||||
encountered it again after we traversed back to the NE, about 700 meters NE of the north edge of the anomaly. The '98 lava here was ~200 m wide, but as we followed it north, it narrowed and eventually pinched out completely about 400 m further north. | |||||||
This '98 lava is probably connected to the southern SeaBeam anomaly. The '98 eruptive fissure along this part of the SRZ was further to the east than we had expected, based on bathymetry. For example, it is 350 meters east of the large cratered mound | |||||||
at 45 52.85'. ROPOS crossed the trend of the '98 eruptive fissure again, 600 meters further north and again young '98 lava. There was a big drained out lava lake in this area. '98 lava was followed another 200 - 300 meters along axis, and then ROPOS | |||||||
crossed another 200 - 300 meters of older lava, before reaching the eastern contact of more new lava. The sub then traversed to the NW and was in '98 lava for ~ 800 meters. Once at the western contact, ROPOS turned to traverse NE, but did not cross '98 | |||||||
lava again. The traverse to the NE was never completed because ROPOS telemetry was lost and the dive ended prematurely. At the end of the dive, ROPOS was about 1000 meters NNE of the last crossing of '98 lava (and west of where it would be expected), | |||||||
and about 1150 meters south of the traverse on Dive R493 (and about 100 meters west of the '98 lava contact from Dive R493 if extended southward). In summary, the '98 eruption appears to be nearly continuous from its northern end, south to almost 1 km | |||||||
south of the southern SeaBeam anomaly. In this area between the two, the eruptive fissure changes orientation from north-south in the north |
Dive R495 | |||||||
Dive Plan: 1) Fluid sampling of southern caldera/upper South Rift Zone vents - Mkr-108, Mkr-113, Castle, Joystick, Coquilles, Bag City. 2) Suction sampling: Mkr-113 Marcus/Moyer, Bag City Moyer/Juniper, Diatom mat on new lava - Tunnicliffe. | |||||||
3) Recover and deploy MTR's at Mkr-113 and Bag City. 4) Sulfide sampling at Castle. 5) Finish Imagenex survey, geology traverse south. | |||||||
ROPOS Configuration: Hot Fluid Sampler, Suction sampler (j1 - j4 and 1 - 4), Niskin, Imagenex, cameras and rock purse | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

7 | 25 | 1520 | 230 | 423778 | 5086580 | stopped on top of pillar, appears that there is a little bit of venting, very slow trickle of non shimmery water. | |
7 | 27 | 1519 | 318 | 423301 | 5087530 | heading NW, 318.2 to the place we started looking for Mkr-108 | |

7 | 37 | 1521 | 271 | 423738 | 5086591 | good fix, due west of target by about 40 meters but no pillars in sight | |
7 | 38 | 1520 | 89 | 423726 | 5086587 | heading straight east over jumbled ropy sheet flow | |
7 | 39 | 1521 | 86 | 423749 | 5086583 | good fix | |
7 | 40 | 1520 | 86 | 423743 | 5086575 | possible vent out of big hole, but we cant get to near it to check it out | |
7 | 44 | 1521 | 81 | 423771 | 5086586 | good fix, and some vent coming out of the base of a pillar, we are going to continue the transect to the east and then come back if there is nothing better | |
7 | 47 | 1522 | 352 | 423773 | 5086605 | venting coming out of hole with worms surrounding it. Dave has decided to sample here | |
7 | 49 | 1523 | 29 | 423312 | 5087530 | we are 20 meters at 329 from the target but have decided to sample from what appears to be two holes | |
7 | 51 | 1523 | 73 | 423772 | 5086607 | placing the temp probe inside one of the holes, | |
7 | 56 | 1524 | 136 | 423781 | 5086593 | good fix, but the temp probe bumped into the side of the vent and now it has collapsed into a swirling mass of floc and shimmering water, the temperature did reach 9 C though. | |
8 | 7 | 1524 | 132 | 423771 | 5086608 | temp is around 13.6 C for max | |

9 | 9 | 1500 | 15 | 423542 | 5087430 | we are now up at 150m and there is definitely a plume, lot o' particles, Dave deduces that there must be more venting going on near Mkr-108 (which we never found) than we discovered | |

22 | 32 | 1537 | 157 | 423149 | 5084622 | Continuing southward traverse. Initially passing over Crevice Vent. Lots of tube worm bushes. Depression here is ~6m dep. | |
22 | 35 | 1539 | 191 | 423021 | 5084511 | A few tube worms on east wall but essentially out of the field. | |

22 | 37 | 1540 | 190 | 423180 | 5084675 | Broken lava, drainouts. Crevice disappears and then reappears. | |
22 | 41 | 1540 | 196 | 423083 | 5084571 | some sort of feature | R495-128 |
22 | 41 | 1539 | 193 | 423196 | 5084236 | hmmm fissure seems to have turned into an inverse fissure | R495-129 |
22 | 39 | 1538 | 190 | 423026 | 5084729 | Broken lava lobes on walls. Crevice only 2 or 3 m dep. Fresh looking pillows in bottom. Is this an eruptive center? Looks in places a lot like the SW Rift on Hawaii. | |
22 | 43 | 1540 | 191 | 423204 | 5084648 | Solid lobate surface. Very glassy surface. Looks like 1998 flow. No ROPOS fixes. | |

22 | 44 | 1542 | 182 | 423058 | 5084513 | Depression ~4 m deep. Then another depression 12 m deep as we lateral to the east. No ROPOS fixes but we are getting cage fixes. | |
22 | 48 | 1542 | 185 | 423004 | 5084622 | Bottom of depression filed with ruble. What else would you expect? | |
22 | 49 | 1543 | 184 | 423110 | 5084499 | Depression is about 5 m wide here and 16-20 m dep. Drainout on west wall. | |

23 | 2 | 1528 | 57 | 423236 | 5083897 | Not getting good navigation. Might head back to cage. We have
a cage fix now. |
|
23 | 6 | 1494 | 175 | 423120 | 5084352 | Heading back to the cage and the cage is in view. Just got a new cage fix. The above fix is good. | |
23 | 8 | 1494 | 171 | 423312 | 5083583 | Cage fix with two tranponders. We are going to head south and apparently will have no navigation. | |
23 | 11 | 1515 | 94 | 423119 | 5084352 | We will head west now and we are going to look at the fissure below. Is it tectonic or eruptive? We will look for newer sheet flows on top and if it has older lavas at depth. | |
23 | 14 | 1547 | 214 | 422849 | 5084565 | Jumbled lavas near fissure, glassy with some hydrothermal
sediment. |
|
23 | 16 | 1543 | 85 | 422966 | 5084677 | Crossing the fissure, maybe. There is some question if the lavas are draping over. | R495137 |
23 | 18 | 1543 | 84 | 423104 | 5084355 | Tube worms near drop off. | |
23 | 21 | 1540 | 273 | 423119 | 5084352 | Heading west to find big fissure. If we don't find it, we will do a traverse to the southwest. Small groups of tube worms. | |
23 | 22 | 1544 | 274 | 423071 | 5084280 | Tube worms at the bottom of a 5 meter deep hole. | |
23 | 23 | 1544 | 267 | 423094 | 5084345 | good fix with 3 transponders with north net. | |
23 | 24 | 1544 | 287 | 423270 | 5084979 | Continuing to the west to find big fissure. Jumbled sheet flows. | |
23 | 25 | 1543 | 284 | 423119 | 5084351 | Drain out 6 meters dep. Not sure if this is the fissure. | |
23 | 27 | 1541 | 271 | 423119 | 5084351 | Back on lobate flows after we passed the drain out feature. | |
23 | 27 | 1543 | 270 | 423119 | 5084351 | Staining and tube worms. | |
23 | 29 | 1539 | 277 | 423119 | 5084351 | P code took a hit. Now moving to the traverse at 270, 60 meters range. | |
23 | 33 | 1542 | 270 | 423119 | 5084351 | P code back, on bottom again and heading west. | |
23 | 34 | 1541 | 273 | 423114 | 5084443 | Going west to the contact and then will angle to the southeast and cross it again. | |

23 | 44 | 1543 | 267 | 423001 | 5084369 | Glass lobate flows very similar to those mapped as the 1998 flows. | |
23 | 46 | 1544 | 267 | 423001 | 5084369 | Flows becoming more pillow like so we might be reaching the end of the flow. | |

22 | 7 | 1502 | 220 | 423694 | 5086786 | ROPOS is in its cage. | |
22 | 24 | 1451 | 231 | 424331 | 5087472 | OK a little brinkmanship | R496-23 |
22 | 23 | 1451 | 239 | 423724 | 5086754 | Continue to raise cage in order to get gray line out to double red tape marks. Line accidentally in the cutter but got out OK. | |
22 | 34 | 1451 | 311 | 423717 | 5086767 | hooked to the bottom of the cage | R496-24 |
22 | 34 | 1451 | 314 | 423667 | 5086915 | Cage end of line drooped attempting to snap hook to bridle. | |
22 | 48 | 1451 | 360 | 423722 | 5086766 | OK this time for sure | R496-25 |
22 | 49 | 1451 | 5 | 423722 | 5086767 | Snap hook recovered with difficulty and attached to ring on bridle. | |

22 | 58 | 1448 | 270 | 423668 | 5086704 | reeling in cage at 4 meters/min | |
23 | 4 | 1435 | 336 | 424482 | 5088083 | Hook came of off where it was hooked to the cage. | |
23 | 6 | 1435 | 348 | 423703 | 5087207 | The hook with a safety clip was somehow twisted, causing the catch to open, and the hook fell off. Now, we have to go back to the seafloor, try to pick up the hook on the end of the line and re-attach it to the chain beneath the cage. Cage now descending. | |

23 | 14 | 1492 | 358 | 423734 | 5086750 | Near the bottom, ROPOS ready to come out of cage, when we saw the spectra line floating up in the water. The line is buoyant, so one end is on the rumbleometer, and the other is on the hook on the seafloor, with a loop floating up in the water column. | |
23 | 18 | 1492 | 272 | 423492 | 5087295 | A-l ROPOS telemetry has died. Network down. | |

23 | 43 | 1401 | 22 | 423703 | 5086779 | Still attempting to get vehicle telemetry back up. Vehicle is in cage, and line is not attached. | |
23 | 46 | 1401 | 63 | 423708 | 5086797 | Bill is working the cube. The telemetry is back up. Could there be a connection? | |
23 | 55 | 1478 | 127 | 423451 | 5087613 | Saw the spectra line again. | |
23 | 56 | 1472 | 115 | 424308 | 5088104 | Asking the ship to move 20 meters West. Stern of ship is currently about 10 meters W of rumbleometer. | |
23 | 58 | 1473 | 284 | 421212 | 5086968 | Situation: Hook was dropped 30 meters brng 010 from the rumbleometer, with line floating in between. Plan :Come down W of instrument, drive up to it, grab line loosely in the claw and drive up, letting the line slip until the hook is within reach. | |

Dive Summary: THE RUMBLEOMETER WAS FREED FROM THE 1998 LAVA FLOW!! Also recovered bactraps and tube worms from Mkr-113 and placed them in BioBox. |
Dive R497 | |||||||
Dive Plan: This dive is at the extensometer site on the north rift zone of Axial. The elevator was deployed with extensometer#4 in one tube and 3 empty tubes. ROPOS will first take #4 out of the elevator and deploy it, then will recover the other four | |||||||
extensometers that were deployed in '98 and place them in the elevator, where they will be recovered at some point during, or after, the dive. Two Imagenex lines will be run after the extensometer work, then on to CASM | |||||||
At CASM site for sampling and observations: tube worm grab; suction samples of mats, animals, FeO (if any present) and vent fluid. Collect GTBs; recover Vemco and HOBO - all at CASM. Deploy MTR and sample sulfides at CASM as well. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. Only positions on NRZ are acoustic nav. All transit and CASM positions are ship at stern. | |||||||

Dive Summary: The dive began with the elevator deployment. Got to the bottom. Removed one extensometer from the elevator and deployed it at position 99E5. When we were heading to recover one of the 98 extensometers Frank noticed that the elevator was | |||||||
was floating behind the ship. We recovered the elevator and proceeded to CASM Vent Field. 17 samples were taken t CASM (suctions for animals and fluids), and tube worm grabs. After many hours at CASM we returned to the NRZ extensometer site. | |||||||
The elevator was redeployed and one extensometer was placed in the tube. We lost power to the sub again and the dive was aborted. |
Dive R498 | |||||||
Dive Plan: Short dive to recover the remaining 3 extensometers with the elevator (elevator prematurely surfaced on Dive R497). | |||||||

15 | 45 | 1536 | 318 | 423157 | 5084638 | We are looking around for a good grab - down into the collapsed area. Lobates still with a light coating of sediment/debris. | |
15 | 48 | 1537 | 140 | 423399 | 5084861 | Old tube worms and crab on edge of crevice. | R501-74 |
15 | 47 | 1538 | 101 | 422817 | 5084266 | Crab full of eggs. Nice view of the wall of the crevice. Some scanty tube worms on the wall. More crabs. | |
15 | 49 | 1537 | 79 | 423163 | 5084654 | Hit the edge of the crevice. Lateraling back along the crevice - moving east now. Crevice is around 5 m dep. | |
15 | 51 | 1538 | 129 | 423152 | 5084633 | Turned the corner in the crevice -now hdg almost due south. Finding a few larger tube worm bushes on the wall. Some larger bushes on the lobates on the roof. Tube worms all along the cracks between the lobates. TONS of crabs. | |
15 | 54 | 1536 | 48 | 423166 | 5084617 | Still on the roof. Looking for the crevice again. Jackpot - down in the crevice there is a huge clump of tube worms. A couple vent fish and a couple crabs. | |
15 | 57 | A bit of flow, but doesn't look like there is much fauna besides a few live tube worms and a couple scale worms. x=3177 y=4620 good fix. Going in for the grab at 1557 | Bio_R501-17 | ||||
16 | 10 | 1539 | 35 | 423178 | 5084641 | Just had a litle bit of an avalanche on top of the tube worm bush. Finished sampling. Keith just said that this is NOT part of the crevice, but just a hole in the roof. | |
Taking a quick look around to see what the area looks like - if there are any more large tube worm bushes about. | |||||||
16 | 13 | 1538 | 269 | 423171 | 5084630 | Tubeworm bush lacking much of the other fauna you normally see. | R501-75 |
16 | 12 | 1538 | 243 | 423170 | 5084630 | All the tube worm bushes on top of the lobate roof look smaller - possibility that they are new worms since the eruption. Can't see any other fauna on the bushes.But the worms of the grab we just took look too large to be new since the '98 eruption. | |
16 | 15 | 1531 | 87 | 423175 | 5084631 | End of dive. Heading back to the cage and coming up. | |
ROPOS on deck at 1711 UTC | |||||||
Dive Summary: This dive began by deploying the time lapse camera at Mkr-33 and collecting a suction sample. Next ROPOS transited to the west side of the 1998 lava flow, SW of Mkr-113 and started a geologic traverse due east. | |||||||
ROPOS started the dive in older lavas and drove east to the contact with younger lava when the dive had to be temporarily stopped because the connector to the color camera light got pulled out and the suction sampler jammed. | |||||||
After a quick turn around, the dive resumed at the western contact - driving east and taking rock samples all the way to the eastern contact between younger and older lavas. ROPOS then drove north along the eastern contact for about 400 meters and | |||||||
then traversed back to the west in lavas known to be '98. A section of clearly older lava was crossed just north of Mkr-113, then back into '98 lava, and finally back into older lava again. 13 rock samples were collected during these two traverses. | |||||||
Finally, ROPOS transited 1.5 km south to the Crevice Vent site to collect a tube worm grab. |
Dive R502 | |||||||
Dive Plan: Objectives of ASHES Dive: 1) Sample high temperature fluids at Hell, Inferno and Virgin. 2) Sample diffuse flow at 2 diffuse flow sites. 3) Suction sample FeOxide and it's fluid at west wall. | |||||||
4) Suction sample sulfide worms at base of Hell (Porkchop) and Hillock/Phoenix. 5) Sulfide worm behavioral observations at Phoenix. 6) Suction sample clams and other large animals, if encountered. | |||||||
7) Suction sample particulates for edifice tube worm grab site. 8) Suction sample oxides to south of vent field. 9) Recover High temp HOBO at Virgin. 10) Recover SOSUS sound source. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||
