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 | 11 | 1523 | 38 | 423777 | 5086605 | no marker visible, but according to fix should be around 20 meters away | |
7 | 13 | 1520 | 177 | 423407 | 5087266 | staining visible on surrounding pillars | |
7 | 14 | 1519 | 182 | 423782 | 5086601 | smaller pillars with visible venting | |
7 | 15 | 1519 | 250 | 423757 | 5086591 | date is wrong on the overlay - it is one day behind | |
7 | 16 | 1519 | 296 | 423757 | 5086593 | coming around to get on south side of pillar, lots of white staining but no apparent venting | |
7 | 16 | 1520 | 11 | 423772 | 5086587 | no venting on south side of pillar | |
7 | 17 | 1519 | 47 | 423772 | 5086585 | possible marker in distance, moving around to check it out | |
7 | 18 | 1520 | 6 | 423778 | 5086589 | good fixes, lots of floc but no marker yet | |
7 | 20 | 1520 | 100 | 423786 | 5086592 | good fixes | |
7 | 24 | 1518 | 251 | 423776 | 5086589 | heading back to first place we saw venting, worms are visible on top of pillar | |
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 | 29 | 1521 | 338 | 423764 | 5086599 | low lying pillar with cracks leading up to it, but no shimmering water, continuing | |
7 | 32 | 1521 | 323 | 423756 | 5086603 | good fix, has us right under cage | |
7 | 33 | 1520 | 6 | 423746 | 5086625 | fix now has us north west of cage, with no pillars in sight | |
7 | 36 | 1520 | 270 | 423305 | 5087533 | jagged, crumbly flow | |
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 | |
8 | 7 | 1524 | 128 | 423772 | 5086609 | starting first sample, max 13.6 C | HFS-17_dfl _R495-1 |
8 | 9 | 1524 | 132 | 423789 | 5086580 | the last was a false start, now we are really sampling! | |

8 | 29 | 1522 | 197 | 423752 | 5086602 | saw 2 Alvin dive weights 1 m at 238 heading | |
8 | 32 | 1523 | 204 | 423769 | 5086563 | heading over ropy sheet flow to get a suction sample | |
8 | 33 | 1525 | 220 | 423756 | 5086558 | found a good pocket of sediment to sample, now attempting to pick up the suction sampler, good fix of x=3755 y=6560 | |
8 | 36 | 1525 | 219 | 423757 | 5086560 | good fix | |
8 | 47 | 1525 | 265 | 423293 | 5087520 | people are now changing their minds whether they want samples here, we are moving into a better area to get suction samples | |

9 | 2 | 1526 | 211 | 423760 | 5086558 | outlet temp probe on suction sampler is working but the inlet temp probe is broken off, we think it broke off sometime before now | |
9 | 5 | 1526 | 213 | 423758 | 5086558 | done sampling here, going to move ship and then head over to Castle, which is 40 m SE | |
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 | |
9 | 12 | 1519 | 141 | 423542 | 5087430 | we are down right under the cage, and found the venting that we first discovered when we got here | |

9 | 33 | 1520 | 161 | 423878 | 5086470 | lot of collapsed lobate surfaces, held up by pillars | |

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 | 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. | |
