Dive R488 | |||||||
Dive Objectives: Same objectives as dives R485 - R487. To Mkr-33 for HFS and suction sampling, then on to Cloud and vents to the north on the '98 lava flow. Biology samples will also be collected. | |||||||
At the end of the dive and Imagenex data will be collected at the western edge of the '98 lava flow. | |||||||
Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions. | |||||||

8 | 11 | 1524 | 225 | 423820 | 5087110 | Now we're getting ready to go to Snail Vent to collect snails! 30 m at 110 will take us there. | |
8 | 13 | 1524 | 226 | 423829 | 5087137 | Saw a scale worm (Lepidonotopodium) covered in bacterial mat- it has no gills. | |
8 | 15 | 1523 | 89 | 423838 | 5087122 | Ropy sheet flows. | |
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. | |

8 | 23 | 1525 | 312 | 423856 | 5087122 | We see Paralvinella sulfincola or pandorae? We're not sure. | Photo-16 |
8 | 24 | 1525 | 307 | 423845 | 5087143 | Photos of worms. We're pretty sure this isn't Snail, it's just further down the crack from Mkr-33. |
Photo-17 |
8 | 26 | 1525 | 304 | 423857 | 5087124 | We're going to take a few minutes to look for the real Snail Vent now since we don't have the right mesh for this. | |
8 | 27 | 1526 | 350 | 423855 | 5087124 | Dead tube worms covered with bacteria near Snail vent. | R488-27 |
8 | 27 | 1524 | 64 | 423852 | 5087133 | Lumpy lavas - looks pretty lobate. We're seeing some dead tube worms overgrown with bacterial white gooey mat. There is orange stuff floating around. Looking at some of these cool lava arches. Very cool. Photos 18 - 20 | |
8 | 28 | 1524 | 79 | 423857 | 5087127 | Still searching for Snail. We think we've found it. | |

8 | 31 | 1523 | 110 | 423858 | 5087142 | We are at Snail! Right near Mkr-N8. There are tons of snails and scale worms too. | Photo-21 Photo-22 |
8 | 32 | 1525 | 73 | 423872 | 5087105 | We can see some pretty intense webby mat, bag creatures, snails, scale worms. | |

8 | 45 | 1525 | 68 | 423884 | 5087067 | The lava is quite flimsy - lots of bacterial action. Note: Julie is using sound effects. | |

9 | 12 | 1524 | 331 | 424902 | 5086973 | Fixes are still NOT good. We're on the west side of Cloud. | |
9 | 14 | 1526 | 336 | 423868 | 5087049 | At Cloud. There are tube worms (small clumps and sparse individuals) and very dense aggregations of polynoids. Will probe for temperature at this location to decide whether to sample here or at the marker location (mkr N4) | |
9 | 17 | 1526 | 330 | 423844 | 5087048 | Worms at Cloud vent | R488-31 |
9 | 18 | 1525 | 341 | 424119 | 5086879 | Lots more tube worms sparsely distributed in the cracks. Don't see any good grabbable clumps yet though. | |
9 | 21 | 1522 | 256 | 423870 | 5087053 | We found Mkr-N4 - there are traps, worms, mat, polynoids and scale worms. | |

9 | 24 | 1525 | 246 | 423710 | 5087512 | Take it back- we're looking west. Temp around 8 and 9 C. | |
9 | 25 | 1525 | 245 | 423742 | 5087112 | The temperature near the bacterial traps is 18 C. The traps already have grazers on them and they were put down a mere 3 days ago! We just saw the new species of worm! | |

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. |
