Date: 2024-03-11

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 be incomplete, 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.

00:02:03 - 20230916T101440Z Note:  watch change, mostly bamboo corals, some dead skeletons
00:03:49 - 20230916T101627Z Note:  comms_adjustment
00:09:30 - 20230916T102208Z Note:  600m from waypoint 2
00:13:48 - 20230916T102625Z Note:  troubleshooting computer: nav
00:16:58 - 20230916T102936Z Note:  slowly moving to waypoint while we wait for troubleshooting for navigation computer
00:19:12 - 20230916T103149Z Note:  continuing to observe bamboo corals as we move slowly forward
00:19:53 - 20230916T103231Z Note:  some dead corals observed
00:22:30 - 20230916T103508Z Note:  data engineer is on their way to fix the issue
00:25:29 - 20230916T103806Z Note:  rock here is botrioidal
00:25:51 - 20230916T103829Z Note:  pseudoanthomastus with long polyps
00:27:10 - 20230916T103948Z Note:  in between the large pillow/lobate flows there are small crevices where sediment is present
00:30:15 - 20230916T104252Z Note:  hexopathes black coral, family cladopathidae, branch splits twice
00:31:40 - 20230916T104418Z Note:  large colonies of 2-3 species of bamboo corals, some are more pink in color, some are white, there are also may sekletons with yellow zooanthids
00:32:42 - 20230916T104519Z Note:  possible candelabra primnoid
00:35:34 - 20230916T104811Z Note:  nav issue was fixed just now
00:37:14 - 20230916T104952Z Note:  calyptrophora primnoid may be the ID of previous zoom
00:40:18 - 20230916T105256Z Note:  another black coral, sponge, and patch of altered rock, tan in color
00:40:56 - 20230916T105334Z Note:  black coral could be paranthepathes
00:42:03 - 20230916T105440Z Note:  the most abundant sp of corals here are various bamboo species, ocassionally we see other primnoids and hemicorallium/paragorgid
00:43:03 - 20230916T105540Z Note:  there are also several bamboo skeletons as well
00:43:32 - 20230916T105609Z Note:  the substrate here is sedimented basalt
00:44:45 - 20230916T105722Z Note:  small_pseudoanthomastus
00:50:19 - 20230916T110256Z Note:  there have been several shrimp
00:53:17 - 20230916T110555Z Note:  continuing to see a high abundance of bamboo corals
00:54:17 - 20230916T110655Z Note:  Actinostoloidea sea anemone
00:54:51 - 20230916T110729Z Note:  increase ins sedimentation here
01:00:13 - 20230916T111251Z Note:  decrease in density of corals as the terrain flattened
01:02:03 - 20230916T111441Z Note:  as there is more of a slope we see a reappearance of a higher density of the bamboo corals
01:04:27 - 20230916T111704Z Note:  as we zoom the substrate here is botrioidal
01:06:18 - 20230916T111856Z Note:  very large sea anemone on sea floor near bamboos
01:06:35 - 20230916T111913Z Note:  bamboos here have internodal branching
01:08:20 - 20230916T112058Z Note:  very steep wall here
01:09:20 - 20230916T112158Z Note:  halosaur
01:09:54 - 20230916T112232Z Note:  in area with more sedimetnation there are some dead bamboos
01:12:05 - 20230916T112443Z Note:  planning next steps towards the waypoint as terrain looks steep in sonar
01:13:52 - 20230916T112630Z Note:  the substrate throughout this dive has been botrioidal flows with fractures/ crevices in between, filled with sediment. on high points there are mostly bamboo corals
01:14:43 - 20230916T112720Z Note:  approaching very steep area indicated in hypac
01:17:50 - 20230916T113028Z Note:  there have only been corals seen and some shrimp, there are not many if any enchinoderms
01:18:32 - 20230916T113110Z Note:  there is way more sedimentation here than previous dive sites
01:22:09 - 20230916T113446Z Note:  grenadier_fish
01:22:50 - 20230916T113528Z Note:  there is a lot more sediment here and dead bamboo corals
01:24:24 - 20230916T113702Z Note:  grenadier may be: coryphanodies sp.
01:25:17 - 20230916T113754Z Note:  larger valley like crevices fill of soft fine sediment
01:25:43 - 20230916T113821Z Note:  also seeing a reappearance of larger boulder rock and flows and healthier bamboo corals
01:26:25 - 20230916T113903Z Note:  stalked eupectelid sponge
