Channel: Nautilus Live Dive Recordings
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.

00:00:42 - 20230917T001320Z Note:  on this large boulder there is a lot of variation in biota: large primnoid fans, crinoids, brittle stars, hemicorallium, cup corals
00:03:09 - 20230917T001547Z Note:  another boulder with large primnoid fans
00:04:48 - 20230917T001726Z Note:  solonaster sea star
00:05:08 - 20230917T001746Z Note:  bathypathes
00:06:29 - 20230917T001907Z Note:  another large poliopogon
00:08:50 - 20230917T002127Z Note:  zoom on poliopogon there are hydroids, some other associates, unable to ID them
00:09:56 - 20230917T002234Z Note:  waiting for a ship move
00:10:56 - 20230917T002334Z Note:  ship move complete
00:11:35 - 20230917T002413Z Note:  thin armed white sea star 5 arms
00:12:20 - 20230917T002458Z Note:  soloasteridae
00:13:30 - 20230917T002608Z Note:  there are many brittle stars on the primnoid fans here, we did not witness this on the previous watch
00:17:14 - 20230917T002951Z Note:  rov_adjustments
00:19:45 - 20230917T003222Z Note:  ~140m from waypoint 8
00:20:09 - 20230917T003247Z Note:  sudden decrease in biota
00:23:10 - 20230917T003548Z Note:  pseudoanthomastus mushroom coral with very dense polyps, it was also fairly thick ~12cm wide, near it was a smaller recruit
00:27:36 - 20230917T004014Z Note:  continually observing transitions of dense biota on rock edges, followed by brief patches of little to no biota, when the density of life decreases, sponges and crinoids still appear to be present
00:28:41 - 20230917T004119Z Note:  brittle star "jumping" off a primnoid fan
00:29:24 - 20230917T004201Z Note:  another bright orange black coral, branching looks like it is more spaced out, may be leopathes.
00:29:44 - 20230917T004222Z Note:  cookie cutter sea star
00:31:19 - 20230917T004357Z Note:  marron colored bathypathes with two squat lobsters, both are red in color
00:34:55 - 20230917T004732Z Note:  zoom on coral skeleton, unable to confirm ID may be a bamboo coral with pink organism overgrowing it
00:36:01 - 20230917T004839Z Note:  poliopogon
00:37:21 - 20230917T004959Z Note:  approaching rock outcrop with a bolosoma stalked sponge, few primnoid fans, a chrysogorgia, yellow crinoids
00:38:08 - 20230917T005046Z Note:  as we approach the underside of this rock feature, there are chrysogorgia, and yellow crinoids,
00:41:41 - 20230917T005419Z Note:  large primnoid fan on the edge of a large boulder with many brittle star associates. there is also a sea urchin, light pink with thin spines: ID may be cidaroida
00:43:32 - 20230917T005609Z Note:  large stauropathes black coral with a yellow crinoid and brittle star associates,
00:44:19 - 20230917T005656Z Note:  near the base of the stauropathes there are also some barnacles: possibly Alcockianum
00:44:50 - 20230917T005728Z Note:  near the large stauropathes there was also a smaller bathypathes with a light pink fine armed crinoid
00:46:01 - 20230917T005839Z Note:  approaching valleys within large boulder rocks with a farried sponge, metallogorgia, and several yellow crinoids
00:46:40 - 20230917T005917Z Note:  several more farried sponge clusters on the side of this rock face
00:47:50 - 20230917T010028Z Note:  ~70m away from waypoint 8
00:48:29 - 20230917T010106Z Note:  another goniasterid sea star at the base of a primnoid
00:49:23 - 20230917T010201Z Note:  steep slope here as we near wp8,
00:50:24 - 20230917T010302Z Note:  as we travel up the wall feature a reappearance of corals: primnoids, cup corals, hemicorallium, chrysogorgia, yellow crinoids
00:51:28 - 20230917T010406Z Note:  hemicorallium with several yellow crinoid associates
00:52:49 - 20230917T010526Z Note:  very large primnoid fan another brittle star leaped off
