Dive R491 | |||||||
Dive Plan: Elevator will be used to gather experiments from Mkr-33, weather permitting. Suction sampling will be done there and at other active vents to the north. Biology and rocks will also be sampled Imagenex survey along western edge of '98 lava flow. | |||||||
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. | |||||||

17 | 19 | 1521 | 114 | 424414 | 5086752 | Removed the launch line from under the anchor. Heading to Cloud vent (N4). | |
17 | 30 | 1524 | 317 | 423845 | 5087046 | Just finished repositioning tubeworms in port side of BioBox. On our way to Cloud. | |
17 | 43 | 1522 | 92 | 423885 | 5087118 | Waiting for the ship to reposition so we can transit to Cloud. | |
17 | 45 | 1519 | 91 | 423889 | 5087115 | Collapsed area just before we reach Cloud - a ridge with a bit of venting, some gastropods and a dense aggregation of the unknown polynoid. | Photo |
17 | 47 | 1522 | 93 | 423886 | 5087066 | We are at Mk-N6 (Cloud). Stirred up a lot of floc while landing ROPOS. Waiting for the floc to clear before we start taking pictures and survey the area. Kim wants video and still photo images to mosaic Cloud vent area. good fix for N6 at 3900, 7115. | |
17 | 51 | 1523 | 268 | 423901 | 5087113 | Trying to go to Mkr-N4 to begin photo imagery work - to the west. | |
17 | 52 | 1523 | 306 | 423896 | 5087114 | At Mkr-N4, good fix. | |
17 | 55 | 1522 | 71 | 423897 | 5087118 | Stopped to try and get a bunch of good fixes to locate precisely where we are. | |
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 |

18 | 25 | 1521 | 101 | 423859 | 5087018 | Imagenex up to 5 m - need to come back down. | |
18 | 26 | 1521 | 120 | 423859 | 5087018 | Imagenex still at 5 meters. Now down to 2.5 m on right and 5 m on left. Turning ROPOS around, heading back towards N4, heading 285. | |
18 | 27 | 1522 | 277 | 423900 | 5087097 | Transect from N6 back to N4. Heading staying roughly between 285-295. | 12 photos |

18 | 32 | 1518 | 126 | 423890 | 5087110 | See N4, set down briefly. Heading 105 and making a transect back towards N6. | 5 photos |
18 | 34 | 1520 | 102 | 423905 | 5087118 | Got out of the venting area. We are going to fly back to N6, go to the eastern edge of the field and then will hop 2 m north, then transect west again. | |
18 | 38 | 1520 | 275 | 423894 | 5087117 | Trying to find mkr N6. | |

11 | 27 | 1506 | 179 | 423234 | 5089205 | Start of Imagenex line W7 (northern end). Ship going south. | |
14 | 45 | 1500 | 88 | 423247 | 5085989 | End of line W7 (south end). Ship moving to south end of Imagenex line W6. | |
15 | 5 | 1500 | 358 | 423311 | 5086038 | Start Imagenex line W6 at 15:0 (at south end going north). | |
16 | 22 | 1501 | 6 | 423305 | 5087098 | End line W6 (south). Ship moving 60 m east to line W5 and will drive south. | |
16 | 33 | 1498 | 189 | 423380 | 5087045 | Start Imagenex line W5 (south end) ~16:27. Ship will be moving south along line. | |
17 | 54 | 1498 | 191 | 423364 | 5086010 | End of Imagenex line W5 (south end). End of dive (due to ground fault in gauge). | |
18 | 9 | 1475 | 188 | 423054 | 5085770 | ROV in the cage and coming up. | |
Dive Summary: ROPOS set a new record of 41 hrs 34 min total wet time, 38.5 hrs on bottom. Dive was terminated by choice (science done, ground fault pending). | |||||||
