Channel: Nautilus Live Dive Recordings
Date: 20/07/2023

This playlist includes recordings of all ROV Hercules dives conducted during a single Ocean Exploration Trust expedition aboard E/V Nautilus. Each dive is divided into two-hour segments. File names include:

Cruise ID_Dive Number_ File(XofX) _Date[yyyy-mm-dd]_Time[hhmmss]z

All files are recorded in UTC-0, the same way they are recorded by ROV Hercules' primary imaging camera.

The chapter observations presented were recorded in the data log in real-time by the scientists and data loggers aboard the ship. These are preliminary observations only. Data has not been QA/QCed or otherwise verified, and may contain inaccuracies, identification and spelling errors.

Scientific/research requests for the full video or for sub-sets of video can be made at https://nautiluslive.org/join/scientists-ashore-program.

0:07:08 - Note: continuing dive 
0:12:32 - Note: should be reaching bottom in about 5 minutes
0:19:31 - Note: we are about 60m off the bottom 
0:20:54 - Note: going 30m altitude 
0:24:05 - Dive Status:  ROV On bottom 
0:24:18 - Dive Status:  ROV On bottom 
0:24:42 - Note: rocky and crusted bottom with patches
0:26:30 - Note: testing out herc 
0:26:56 - Note: noticed a sea lily 
0:28:04 - Note: steeper than expected so just testing rov
0:28:59 - Note: holding wrench another 5m
0:30:47 - Note: running rov checks 
0:32:17 - Note: going auto depth 
0:33:41 - Note: zooming into arm to test camera 
0:38:35 - Note: considering traveling parallel to the slope; still trying to test the ships capability 
0:39:15 - Note: moving steadily up slope roughly north
0:39:46 - Note: noticing a sponge 
0:41:23 - Note: sponge is looking like euretidae 
0:42:07 - Note: seeing some caulophacus
0:43:38 - Note: continuing upward; still not super dense noticing more coral and sponge
0:45:47 - Note: possible bloosoma sponge and bamboo coral 
0:48:07 - Note: bamboo fan 
0:49:44 - Note: swimming polychaete
0:50:08 - Note: anthomastus mushroom coral
0:52:28 - Note: continuing up slope rocky heavily encrusted; steep with sparse bio including bamboo coral and various sponges
0:54:26 - Note: shrimp zoom 
0:56:05 - Note: continuing up steep slope rocky encrusted 
0:57:35 - Note: checking to see if there is an open spot to collect a rock sample 
0:58:59 - Note: continuing to move up slope 
1:01:59 - Note: waiting on ship move ; considering possible ways we can get shallower
1:03:29 - Note: doing a 30m ship move to hopefully position up slope 
1:05:59 - Note: zooming in on rocky area 
1:06:40 - Note: ophiuroid associate on bamboo
1:09:12 - Note: stopping to try and collect a rock 
1:09:28 - Note: the ship is doing well with the setting at 40 degrees 
1:10:26 - Note: continuing to move 
1:11:42 - Note: moving to a more flatter surface
1:14:42 - Note: caulophacus sponge
1:15:38 - Note: now we are over more flatter sandy area seeing more flattering sea lilies
1:16:45 - Note: doing good with the ship moves
1:18:44 - Note: continuing slightly up north 30m
1:24:15 - Note: spotted a ophidiid fish
1:28:00 - Note: continuing up slope to wp 1; small moves
1:28:25 - Note: going up 20m 
1:31:22 - Note: holothurian (sea cumcuber)
1:31:45 - Note: botryoidal crust texture 
1:32:17 - Note: going another 20m 
1:33:22 - Note: seeing multiple different types of bamboo 
1:35:40 - Note: another cusk eel 
1:36:27 - Note: going another 20m at 105 degrees at 0.2 knots
1:37:21 - Note: ships move have been able to keep in control so should be good to get close to wp
1:37:44 - Note: continuing up slope 
1:40:06 - Note: about 2600m in the shallow area where we are seeing some higher density of bio 
1:40:22 - Note: moving another 20m at 200 degrees 
1:41:09 - Note: sea anemone 
1:43:14 - Note: started in western direction but there is still some uncertainties about to run test now
1:45:17 - Note: during dive we have seen a variety of bamboo coral, shrimp, cusk eel, sea anemone, and sea lily
1:46:43 - Note: the bridge does not feel comfortable with the ship movement; considering going 90 degrees up north
1:47:13 - Note: was not comfortable going 300 degrees west
1:49:28 - Note: north is still uncomfortable; south/southwest is possibly the best move; continuing the 20 degree moves just to make more progress
1:49:43 - Note: making call on whether to continue the dive or not 
1:51:07 - Note: doing 20m at 0.30 
1:52:37 - Note: continuing to make small steps
