| 0842 | 1494 | Nav dropped out. |
| Time | Heading | Depth (m) | Comments |
| 0922 | 2698 | ship fix 150m 181 from WP1. 23m off bottom | |
| 0924 | 184 |
Landing site: On bottom. Striated pillow lavas with bread crust surfaces, age 1.5, light dusting of sediment, few small pockets here and there. |
|
| 0925 | 181 | 2721 | Mostly bulbous pillows age 1.5 with some buds seen, high relief sea floor (few meters locally), lots of small pillow mounds and deeps between them. No elongate pillows. |
| 0929 | 2721 | Looking for sample 1 close to landing site. Ship fix: 73m 32° to WP1. No NAV in sub. | |
| 0935 | 2731 | Still looking for sample 1. Pillows with rare lobates. | |
| 0943 | 2729 | Sample 3350-1 - piece of lobate (mis-spoke on tape) 15x15x? cm, Mn-oxide coating, triangular shaped. | |
| 0952 | 2729 | Ship fix: 80m 038° to WP1. No NAV in sub. | |
| 0953 | 070 | Underway to WP2 | |
| 0956 | 073 | 2726 | Moving to WP2. Estimated speed is 1 kt. In sedimented pillow region, both elongated and bulbous forms. Still high relief sea floor, lots of ornamentation on bulbous pillows. Sediment in semi-continuous pockets. Dominant orientation to elongated pillow forms is ~ 340°. |
| 0959 | 073 | 2711 | Flying 5m off bottom. Still in pillows. Slowly heading upslope. |
| 1000 | 073 | 2709 | Heading up stepped slope. |
| 1001 | 069 | 2708 | Heading up 5°slope of pillows. Some ornamentation, mostly elongated. |
| 1003 | 071 | 2699 | Ship fix: 980m 68° from WP2. |
| 1005 | 071 | 2692 | Local summit of steep-sided hill of bulbous pillows. Same sediment age |
| 1007 | 069 | 2700 | Similar pillow terrain, bottom sloping away from us. Smaller lobates intermixed with bulbous and elongated pillows with good striations. Age 1.5. Hill is big mound of pillows. No evidence yet of fissures. |
| 1009 | 069 | 2706 | Moving uphill again on heading of 069°. Map predictions are working. |
| 1010 | 070 | 2705 | Pillows, somewhat less relief to the sea floor. Smaller pillows. Transitional to lobates. Ascending second of two N-S humps that make up ridge axis in this area. Driving over a deep, narrow fissure, trending ~030° to the sub (090° absolute). Could see ~2m down to bottom, 15 cm across. Sediment cover is still the same. |
| 1013 | 067 | 2699 | Going up steeper slope, picking up more fissures. Just passed another N-S fissure, 0.5m wide (said trend was 330 from sub = 040 absolute but I am skeptical of this). Could see >2m down to bottom. Slightly less sediment cover here. Can see shimmering off glass surfaces. Elongate and ornamented bulbous pillows but transitional into lobates. |
| 1014 | 069 | 2694 | More fissures. Transitioning up steep slope into pure lobate flows. 10m of shallowing should remain until reaching eastern axis summit. |
| 1015 | 068 | 2688 | Some fissures are wider and deeper. Can see 6m down one to bottom. 2 to 3 m across. Shelly crusts on lobates, spillout from lobate observed. Still some striated pillows evident. |
| 1016 to 1016.5 | 069 | 2686 | Another two fissures: 0.5m and 1m across. Somewhat of a sinuous lineation. Could see down it pretty far. Also seeing collapses in lobates with jumbled surface in bottom (talus - no flow exiting it). |
| 1017? | 070 | 2686 | Another fissure, heading is ~340°, >1 sub length across, 6m down to floor in part, then drops even further on eastern edge. Mesotech image being recorded on video. |
| 1018 | 069 | 2685 | Another very deep fissure cutting lobates. Ridge up center that is lower than two sides. Age 1 lava? Series of deep parallel fissures, can't see bottom. Walls difficult to see but it looks to be a series of shelly lobate flows, mostly uncollapsed. Flow surfaces fractured near fissures. |
| 1019 | 069 | 2687 | Passed over significant number of fissures. Looking for sample from lobates here. Fissures affecting depth reading? |
| 1020 | 070 | 2690 | Fissure significantly wider than the sub. Crossing it ~perpendicular. |
| 1022 | 2693 | More fissures. Alvin video shows young lava flooring a fissure into old lobate lavas. Looking for sample of older lobates. Anenomies on lavas. | |
| 1023 | Alvin video shows very clearly that the young lava is ponded right up against the edge of a fissure but does not spill into it. | ||
| 1024 | 117 | 2692 | Looking for sample. Now over lobate lava that looks much younger and less sedimented. Spaghetti worms on younger flow. Big collapse pit to port side. Can see bottom but looks like 8-10m deep. Can see stacked older lobates in the walls. 5-10 cm thick. Flow contact. |
| 1027 | 2693 | In collapse pit of lobates. | |
| 1031 | Sample 3350-2 into basket 1a. Fist-sized piece of lobate crust. Area is covered with spaghetti worms. 10-20m from contact from fissured lobates. Lobates looked younger than pillows we saw earlier. | ||
| 1032 | 064 | Underway again. | |
| 1033 | 2694 | Spaghetti worms plus small brown-green animals with little heads of 2-5 cm tall (barnicles?). Lavas look to be age 1. Seeing individual mussels in places. No clusters. Diffuse flow site?. | |
|
1035 to 1036 |
Transiting out of Spaghetti worm area. Lava morphllogy is now lobates with occasional pillows. Ornamented buds. Low relief sea floor. Somewhat more sedimented. Flow Contact back into age 1.5 lavas, meaning young material was a thin sliver on this sub traverse. | ||
| 1037 | Hydrothermal staining on lobates. No spaghtti worms. Limited biology. Elongate 5m long breadcrust striated pillows. Lobates as well. | ||
| 1039 | 010 | 2698 |
Moving slowly looking for sample 3 in lobate/pillow terrain. Localized hydrothermal staining. Both Fe-oxide and whitish staining in spots. Alvin video clearly shows that we are skirting back and forth over a contact between younger and older flows between time 1039 and 1053. |
| 1044 | 2699 |
Flow Contact back into young lavas. Sample 3350-3 - 2 pieces. Smallish lobate bud into basket #1b; larger piece into basket 4 with sample 1. Very different looking materials so no problem. This sample appears to be from the younger material, based on appearance and phenocryst content. |
|
| 1046 | 067 | 2697 | Underway to WP2. No sub nav. |
| 1047 | 2699 | Ship fix that says we are ~200m at 073° from WP2. | |
| 1049 | Alvin Nav: 204m at 080° from WP2. | ||
| 1050 | 076 | 2700 | Relatively young lobates, age 1. |
| 1051 | 2702 | More biology: crabs (Galatheates according to Bob), anenomaes, sponges, stuff floating in the water, pretty limited in terms of biomass. | |
| 1053 | 2706 | Out area with enhanced biology; still in lobates with now some pillows. Age. Have crested eastern limb of axis? | |
| 1054 | 075 | 2706 | More pillows, greater sediment cover along a gradient towards off axis. |
| 1055 | 2711 | Sedimented pillows with bread crust-striated surfaces. Mostly bulbous pillows. 3m long one. More relief to sea floor 5m of vertical relief within pillow mounds. | |
| 1056 | 076 | 2716 | Back into age 1.5 lobates, same sediment cover. Maybe a tiny bit less. Transition into a small collpase. Jumbled-hacked lobate surface on flow with less sediment cover again. |
| 1058 | 075 | 2715 | On a local high of jumbled sheet flow. Looking for next sample |
| 1104 | 2718 | Sample 3350-4 being taken from jumbled sheet flow. | |
| 1106 | 2718 | Ship fix 100m past WP2 | |
| 1108 | 003 | 2718 | Underway to WP3 on new heading, |
| 1109 | 345 | Jumbled sheet flow. Age 1 - 1.5 glistening glass surface. No biology. | |
| 1111 | 344 | 2713 | Jumbled sheet flow. |
| 1112 | 2713 | Ship fix: 1538m 340° to WP3 | |
| 1113 | 2712 | Lots more biology again: Crabs, worms in the water column, puffy animals on a little stalk, starfish. Age <1 to jumbled sheet floor. No sediment. Surface of sheet flow is rubbly, hackled, undulating on top. Small pits and rises, no lineation directions. | |
| 1116 | Cluster of greater extent of biology. Lots of mussels in local spots. Generally jumbled sheet flow with some tabular sheets. | ||
| 1117 | 2711 | Active high temp. hydrothermal area in a collapse in the flow surface. | |
| 1118 | 073 | 2711 | Active hydrothermal chimney. Main chimney is in front of sub at heading of 073°. Height of chimney is 6-10 m? Black smoker. Most activity on chimney is from small spires near base. Top is mostly inactive but there is shimmering water around it. Multiple generations of growth are evident. Second active smoker identified to starboard. |
| 1120 | 090 | 2708 | Heading toward second, much more active chimney. Lots of black smoke. First chimney is on port side. Lots of mussels in the area. See about a dozen fish all swimming in same direction near base of chimney on 3 chip. Also took some handheld digital stills of them. |
| End of Alvin & 3 Chip Videos 1 of 3; Start of Alvin video 2. 3 Chip on for a moment then shut off. Not on until 1210. | |||
| 1123 | Still at second chimney. | ||
| 1130 | 345 | 2708 | Underway again from vent site. No samples. Tourist stop. Hackled sheet flow beneath us. Lots of biology at base of chimneys. |
| 1134 | Flow Contact: Young hackled sheet flows (with anenomaes, starfish) transitional to lobates into age 1.5 pillows. Crossing between eastern and western fissure zones? High temperature vents must have been on Eastern zone. | ||
| 1135 | 354 | 2713 | Local area of very high sediment deposition. Only tops of pillows and extinct chimney-lets poking out. Dead vent site where the chimneys have turned mostly to orange sediment. |
| 1137.5 | 347 | 2712 | Sedimented elongated pillows. Some ornamentation. Small ridge to port. Spill out from pillow. Age 1.5. In between Eastern and Western "fissure" zones. |
| 1140 | 347 | 2706 | Sedimented lobates with occasional pillows. No biology. Age 1.5 |
| 1141 | 2706 | Heading up a small hill in age 1.5 pillows. Ornamented bulbous pillows. | |
| 1144 | 347 | 2694 | Moving upslope. Lobates transitional to pillows. Age 1.5. At crest of axis between Eastern and Western fissure zones? |
| 1145 | 348 | 2691 | White Octopus. |
| 1146 | 347 | 2689 | More elongate pillows. Moving upslope again. |
| 1147 | Ship fix: 834m 325°to WP3. Small fissures (~10-15 cm across) on Alvin video. | ||
| 1149 | 327 | 2682 | My estimate: 750 m from WP3. In age 1.5 pillows transitional to lobates. More small fissures on Alvin video. |
| 1151.5 | 2680 | Picking up spaghetti worms on flow. Moving from old pillows into young lobates. Flow Contact. Confirmed seen on Alvin and 3 Chip videos. | |
| 1153 to 1154 | Large Clam bed. Most of them are dead. Also some dead mussels. Barnacles on rocks. Lots of biology. Terrain is littered with clam shells. Almost no bear rock visible but what is has some hydrothermal staining. Lava age 1. Inactive diffuse flow site? | ||
| 1154 | 322 | 2688 | Out of clam bed. Can see flow better now. Same age as pre-clam bed lobates. White staining on some rocks. |
| 1155 | 2688 | Seeing both lobates and pillows. Flow Contact. Young lobates into old pillows on Alvin and 3 Chip videos. | |
| 1156 | 324 | 2687 | Going upslope again in older pillows (~350 m from WP3). Fissures. |
| 1158 | 340 | 2681 | Seeing large collapses and fissures heading ~N-S. |
| 1159 | 326 | 2679 | Moving upslope again to WP3 in older pillow terrain. Age is solid 1.5 |
| 1200 | 321 | 2677 | Big fissure going at tend of 010 to sub (~ N-S). Seeing swarm of deep fissures. Walls look to be lobates. Can't see bottoms. Age 1.5 lobates, dusting of sediment on all surfaces, some sediment in pockets. Also seeing some localized fissure-perpendicular cross-cutting collapses. |
| 1201 | 325 | 2679 | Another deep 2m wide fissure in lobates. Seeing uncollapsed lobates in the wall. Fissures occur in swarms between 10 m wide zones of undisrupted lobates. Corrected earlier impression on tape of dead musseld bed as being somewhat east of Western fissure zone. |
| 1202 to 1203 | 2682 | Ship fix: 400m 325° to WP3 (Tape says heading 375° but I corrected myself on tape side B). Just passed into another area of dead mussels in age 1.5 pillow lavas. Inactive diffuse flow site? | |
Audio Tape 1 of 1 - Side B
| Time | Heading | Depth (m) | Comments |
| 1203 | 329 | 2688 | Old sedimented bulbous pillows. Outside of bio area but still seeing mussel debris hear and there. |
| 1208 | 328 | 2692 | Fissured bulbous pillows. Striations on pillows, age = 1.5. Can see pillow forms in wall of 0.5m wide fissure, which is trending roughly N-S. |
| 1210 | 328 | 2685 | Old pillows, age 1.5, no biology. No Nav yet. Start of 3 Chip tape 2. |
| 1212 | 327 | 2682 | Old pillows, age 1.5. |
| 1214 | 2688 | small fissure, 10 cm across. Crinoid in fissure. | |
| 1215 | 327 | 2683 | Going upslope again. My DR puts us 100m from WP3. Age 1.5 pillows transitional to shelly lobates, some collapsed with little drainouts. |
| 1216 | 329 | 2678 | Ship has us at WP3. (40 m past). We are still going upslope and WP3 is on a local high, so we feel our DR is better. |
| 1218 | 328 | 2675 | At WP3 by DR, heading to WP4. Area of dark sea floor in side scan is older pillows. Rough sea floor. Ship fix: 900m 082° to WP4. |
| 1218.5 | Turn to WP4 | ||
| 1220 |
071 X 1415 Y 976 |
2684 | Same terrain, heading downslope. |
| 1221 | 071 | 2690 | Going uphill again (local depression). Crossing over very deep fissure trending N-S (can't see bottom). Truncated pillows in walls. Right next to this is a small depression with very sedimented pillows and small extinct chimneys. There is an orange hydrothermal component to sediment. Extinct high temperature hydrothermal vent site. |
| 1223 |
082 X 1507 Y 1003 |
2683 | Age 1.5 pillows and fissures. Small pillow spillout forming a 1m wide sheet flow. Must be crossing complex relief area on sidescan again. |
| 1224 | 088 | 2682 | Another fissure, 0.5m accross. Couldn't see bottom. |
| 1225 |
X 1591 Y 1010 |
2682 | Deep fissure, 1m across |
| 1226 |
089 X 1642 Y 1019 |
2680 | Swarm of small, 10cm across fissure in pillows transitional to lobate lavas. Age 1.5 |
| 1227 | 089 | 2679 | Lobate lavas, Age 1 or slightly older. Looks like distal end of Animal Farm flow that we saw to the north on dive 3346. Looking for a sample. |
| 1229 | 2680 | stopping to take sample 5. | |
| 1231 | 2680 | Moving on/did not take sample (too difficult due to kicked up sediment) | |
| 1233 | 081 | 2678 | Underway for 2 minutes, looking for age 1-1.5 lobate sample. No shimmering of glass from beneath sediment. |
| 1235 | 100 | 2679 | Lobates, although much more hackled surface locally. Stopping again for sample 5 in collapse. Large collapse sheets and jumbled up terrain. |
| 1237 |
X 1732 Y 1024 |
2677 | Sample 3350-5 - Crust from lobate lava, into basket 8. Large, tabular piece. 25 cm in longest direction, triangular in shape. |
| 1239 | 083 | 2676 | Passed over another two very deep fissures. Got one on Cit-camera. |
| 1241 | 2680 | Lobate lavas, age 1-1.5, looks like animal farm. Seeing lots of closely-space small fissures (10cm across, <1m apart). Also seeing a large fissure. Surface of lobates between fissures is hackled and broken up. Flow is tectonized by fissures in local areas but returns to normal-looking animal farm lobates just a 2-3 m from fissures. | |
| 1244 | 084 | 2687 | Age 1.5 lobate lavas, picking up a few crabs, anenomaes, plenty of fissures too. Are eastern/western fissure swarms continuous here? |
| 1246 | 082 | 2689 | Entering another mussel bed right next to another N-S trending fissure. Seeing a few Spaghetti worms, mussels and crabs. Diffuse flow site. Flow contact: into relatively young looking lobate lavas transitional to sheets with a hackled surface and almost no sediment on them (age 1). |
| 1248 | 075 | 2689 | Stopping for sample 6. Settling into small collapse (0.5m deep) in a lobate. Lots of anenomaes. Lava looks young (age 1). |
| 1251 |
X 1992 Y 1078 |
2690 | Sample 3350-6 - Into basket 5b. Lobate crust, 5cm thick, triangular in shape, 25 cm in length, digital picture #10. Ship fix: 250m 088° to WP4 |
| 1253 | Large quantity of mussel and clams debris on sea floor, lots of dead, open shells. Living crabs around, fish and shrimps in the water; anenomaes on the lava. Similar to past approaches to bio sites. | ||
| 1254 | Stopping again for mussel sample just a few m away from rock sample 6 site. Lot's of live mussels put into bio box. Diffuse hydrothermal flow site, should be ~250m from WP4. Just over the Eastern fissure zone? On all 3 crossings we see young lavas, lots of biology, and on second of 3 crossings we saw the high temperature hydrothermal vent site. | ||
| 1256 | 2690 | Sample 3350-7 - into bio box. Lot's of live mussels, one crab. | |
| 1303 | 080 | 2689 | Underway from mussel station. Passing into another area of lots of mussels and clams, new diffuse flow site is east of sample 7 locale. Lot's of anenomaes and barnacles growing up from the rocks. |
| 1306 | 080 | 2687 | Out of bio area. Lobate lavas with localized white staining on surfaces, age 1 (limited sediment cover - but older than young flow in the south). |
| 1308 | 080 | 2691 to 2692 | Lobate into pillow transition. More sediment here but really a smooth transition. Still seeing glistening of glass from lava surface. Near WP4. Looks just like northern area at edge of axis: lobates transitional to pillows, picking up more sediment in a gradient. |
| 1309.7 | 082 | 2693 | Flow contact: Young lobates into Age 1.5 pillows seen on Alvin Video. |
| 1314 | 114 | 2706 | Age 1.5 pillows seen on Alvin video. |

| 1315 | 2349 | 1141 | 2710 | At WP4, lobates and sheets (ship fix: 50m 125°). Age 1.5. Stopped for a sample. | |
| 1318 | 295 | 2714 | Looked for a sample without success. Will slowly make for WP5 and sample asap. | ||
| 1319 | 290 | Ship fix 850m out from WP5 | |||
|
1324 (1323) |
2714 | Stopping for sample 8 in collapsed sheet flow transitional to lobates. Got small lava pillar with linear features on it (~2m high, 10-15 cm across on top, with lobate crust) off to port side. Some sediment in water being kicked up by the sub. | |||
| 1326 | Sample 3350-8 - into basket 5a. 25-30cm x 10 cm long tooth-shapped piece of lobate crust with Fe staining on it in criss-cross patterns. | ||||
| 1329 | 280 | 2712 | Underway again to WP5. No nav yet. | ||
| 1332 | 2704 | Traversing bulbous pillow terrain transitional to lobates, same age as recent lobates. Ornamented with buds. No elongate pillows. Can clearly see pillow above lobate at base (stratigraphically same or younger). | |||
| 1333 | Alvin and 3 Chip videos number 2 end here. | ||||

| 1339 | 294 | 2687 | Lobates, age 1? | ||
| 1341 | 292 | 2686 | Lobates, some small collapses (where just crust has dropped in). Lava looks younger. Age 1.25. No biota. Roughly halfway to WP5. | ||
| 1342 | 292 | 2687 | Seeing a few Spaghetti worms (diffuse hydrothermal flow site?) Transitioning. Lobates and striated pillows. At eastern fissures again? | ||
| 1344 | Lobates with hackled surface, some linear features roughly parallel to sub heading. Passing over a small fissure trending N-S. | ||||
| 1344.3 | 1999 | 1194 | 293 | 2686 | Flow Contact: young lobates into age 1.5 pillows. |
| 1345 | second very narrow fissure. Can't see bottom. Cuts cleanly through flow. Can see lobates in the wall. Age = 1 to 1.25. Also a 1m wide, very deep fissures. | ||||
| 1347 | 2681 | Back into more sedimented lobates with large fissures. Western fissure swarm. | |||
| 1349 | 2683 | looking for sample 9 in fissured lobates. stopping sub. | |||
| 1351 | 1911 | 1223 | 2683 | Sample 3350-9 - lobate crust into basket 3b, digital photo #12. | |
| 1353 | 1907 | 1230 | 290 | 2678 | Underway for 1 minute. 364m 296° from WP5, starting to get some Nav. fixes in the sub. Passed over another fissure that appeared to be a fault. Bob and Eric feel that there was vertical offset across the fault. High side of fault was to the west, 3m offset. |
| 1355 | 1867 | 1243 | 293 | 2678 | Ship fix: 350m 300° from WP5. Alvin fix etc from video. |

| 1358 | 1798 | 1266 | 293 | 2676 | Stuff from Alvin video. |
| 1359 | 2677 | Lobates, age = 1.5. Passed out of fissure area? | |||
| 1400 | 301 | 2679 | 0.5 m fissure, too deep to see bottom. Lobates | ||
| 1401 | 302 | 2678 | Transitioning into pillows. Still see fissures. Maybe turn here and bipass WP5? | ||
| 1402 | 1674 | 1339 | 303 | 2680 | Crossing very large fissure (>10m across, can't see bottom). Can see pillows and lobates in the wall. Mostly pillowed surface of age 1-1.5, good bread crust striations. We are still in Western Fissure Zone. |
| 1403 | 075 | 2682 | ~100m from WP5. Turining to WP6. Age 1-1.5 ornamented pillows. | ||
| 1404 | 1643 | 1355 | 075 | 2682 | Stuff from Alvin video. |

| 1405.8 | 1671 | 1364 | 2681 | Nav fix. | |
| 1406.6 | 1768 | 1395 | 075 | 2677 | Alvin video shows us passing over large fissure. |
| 1409 | 1772 | 1400 | 2676 | Lobates, hackled surface. East of Western fissures? Seeing some local collapses. Lobates look to be age 1-1.5. Is this the animal farm flow? Lobate collapses have crenulated surfaces around the pits, rubble on bottoms. Trend in many directions. Pits are ~2m deep. | |
| 1411 |
1732 1832 |
1415 | 078 | 2675 | Crossed another N-S fissure. Fissures every few m. Are these Eastern Fissures? |
| 1412 | 1869 | 1422 | 078 | 2674 | Another fissure. Flow surfaces of age 1.5 lobates are very broken up. Large crinoid down in fissure. |
| 1414 | 2678 | Another fissure. | |||
| 1417 | 1787 | 1505 | 2684 | Another narrow (10 cm across) N-S fissure. | |
| 1418 | 082 | 2684 |
Seeing crabs and fish again. Definitely younger looking lobate lavas. Just gone over contact again. Mussels and clams are seen in the distance. Flow Contact: Age 1.5 lobates into younger lobates. |
||
| 1420 |

1814 (bad) | 2685 | Crabs and anenomaes strewn about. Not a large concentration but lots of them around. Not many mussels. Diffuse flow site? | |
| 1423 | Sample 3350-10 - into basket 9. Piece of young lobate crust with white worms on bottom. 25 cm in length. Triangular shaped. Diffuse flow site, saw shimmering water on Alvin video. Is this the eruptive fissure? | ||||
| 1424 | 082 | In younger lavas covered with Spaghetti worms and smaller white worms. Looks like young flow; Bob sees mussels ahead. Sea floor transitions quickly into being covered with biology. | |||
| 1428 | 083 | 2690 | Out of biological area in lobate flow with occasional budded pillows. Area of biology appeared as a sliver in center of this flow. Pretty clear kipuka on Alvin Video. Flow Contact: younger lobates into age 1.5 lobates. | ||

| 1432 | 84 | Then moved in curtain folded and locally jumbled sheet flow. Overall trend is 225° relative to sub (310° absolute). | |||
| 1433 | Trying to get one last sample. Almost out of battery power. | ||||
| 1434 | 2365 | 1517 | 2699 | Stop for sample. | |
| 1438 | Sample 3350-11 - into basket 3a, small piece of sheet flow. About 300 m from WP6 | ||||
| 1439 | 2693 | Off bottom. Can see in Alvin video as we ascend that this sample site is at the edge of a collapse. | |||
