Description
14:32:34       Descent   Sipper powered up. Pilot had visual on head registering.
14:39:30       Descent   Communication established with AMS.
15:47:10     2502     Arrived at bottom, video started, began transit to Ty/Io.
15:48:02       Ty/Io   Arrival at Ty/Io.
15:51:10           Observed two large pillars, possible sulfide collection candidates, at least two black smokers on each pillar.
15:53:40 4728 77640   Ty/Io   Possible sulfide collection candidate spotted. Riftia at base, white material at top of pillar below sulfide orifice.
16:02:07 4732 77634   Ty/Io   Sipper pump on. Sample collection attempted. Sample lost (too friable).
16:04:01 4732 77634   Ty/Io   Sipper wand put back in basket.
16:08:48 4719 77605   Ty/Io   Spotted another possible sulfide collection candidate. Mussel bed near base of pillar.
16:12:18 4720 77600   Ty/Io   Structure collection attempted. Chimney knocked over.
16:14:12           Looking for another sulide structure to collect.
16:17:50 4719 77614   Ty/Io   Inspecting new sulfide structure — 2 orifices giving black smoke.
16:21:00 4721 77614   Ty/Io   Sipper pump on.
16:26:21 4721 77614   Ty/Io 5.9°C Sipper #1 taken from bottom of flow. Temp = 5.9°C.
16:29:00 4721 77614   Ty/Io 2.4°C Sipper #2 taken from bottom of flow. Temp = 2.4°C. Concern about temp probe on Sipper. Wand appears to be in flow, temp. readings still low.
16:30:41 4721 77614   Ty/Io   Sulfide structure collected — small top of chimney, placed in port side box of large Biobox (coffin)
16:32:51 4721 77614   Ty/Io 253.9°C Using high-temp. probe to test Sipper temp. probe; 253.9°C measured
16:36:00 4721 77614   Ty/Io 90–95°C Sipper #3 fired in middle of flow after sulfide collection.
16:38:36 4719 77603   Transit   Transit to BIO-9/ P-vent.
16:39:42 4723 77598   Transit   Attempted still shots — no good. Trying to find P-vent.
16:58:00 4661 77941   BIO9   Hand-held of ASU Frying Pan (Morgan), 3-chip video as well (video is dark). Very little precipitation on Frying Pan, mainly white mineralization on base.
17:10:06 4651 77941   BIO9   View of three Harold traps. One with a lot of white flocculent material, the other two were bare, lots of shimmering water flowing through all three.
17:14:11 4651 77942   BIO9   More hand-held video of Harold traps. Lots of white floc observed in water around the traps.
17:15:17 4651 77942   BIO9   Pan & Tilt video of Harold traps, mainly on one out of three; not much white material observed on this particular trap.
17:20:49 4650 77941   BIO9   Removed AMS wand from basket. Cap #3 was off of the wand prior to sampling.
17:29:57 4650 77941   BIO9   AMS sample #1 — only 64 mls pumped at first, increased to 400 mls (we thought we had moved on to AMS #2, but were still on AMS #1).
17:38:13 4650 77941   BIO9   Videotapes changed, AMS #2 taken — 191 mls.
17:40:27 4650 77941   BIO9   Downloaded AMS data to laptop.
17:48:00 4650 77946   BIO9   Positioning for Alvinella collection.
17:49:00 4653 77946   BIO9   Visual and video of Mosquito probe; no hot worms found.
17:53:00 4653 77946   BIO9   Sipper pump on.
17:55:00 4653 77946   BIO9   Sipper wand bent.
17:59:00 4653 77946   BIO9   No good temp. above 50°C in worm holes, Sipper pump off and wand put back in basket.
18:03:13 4653 77946   BIO9   Hand-held video of ASU Frying Pan (Morgan).
18:03:49 4659 77946   BIO9   Probing for 50°C worms, Sipper wand dropped and retrieved.
18:12:32       BIO9   Moving around to other side of pillar to find hot worms.
18:18:44 4652 77948   BIO9   Sipper pump on.
18:21:16 4652 77948   BIO9 51°C Sipper # 4 taken — water around worm tubes.
18:23:59 4652 77948   BIO9 51°C Sipper # 5 taken. Same spot as Sipper #4.
18:29:39 4652 77948   BIO9 37.6°C Sipper # 6 taken.
18:30:00 4652 77942   BIO9   Collecting Alvinella for starboard side of large Biobox. Approx. 1– 5 worms?
18:40:00 4652 77948   BIO9 45–100°C (probably at 75°C) Sipper # 7 taken from scar of Alvinella collection — lots of variation in Sipper temp. probe (negative 500 to 500°C when moving it around. Stabilizes when held still).
18:43:00 4652 77948   BIO9   Collecting worms for DISSR/Shank sampler. Good 3-chip video.
18:45:32 4652 77948   BIO9   Collecting large clumps of worm tubes for Shank sampler.
18:48:50 4652 77948   BIO9   Shank sampler activated — unsure of how many worms.
18:52:00 4652 77948   BIO9   Opening DISSR.
18:55:07 4652 77948   BIO9   One worm into DISSR.
18:57:00 4652 77948   BIO9   Sipper pump on.
19:03:00 4652 77948   BIO9 40–90°C Sipper #8 taken from scar from Shank/DISSR worm collection.
19:05:30 4652 77948   BIO9   Trying to collect more worms for Biobox.
19:07:20 4652 77948   BIO9   On bottom troubleshooting opening large Biobox.
19:13:00       BIO9   Hand-held of Harold traps.
19:14:00           Changed videotapes.
19:20:04           Batteries running low — permission to surface from Atlantis. Noticed right chamnber of Biobox not sealing. Used manipulator to pin lid shut during ascent.
19:22:15           Began ascent, asked pilot for DBL NAV screen shot.
