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. Please note that the YouTube videos may be incomplete and are not the full-resolution video. For press inquiries or licensing requests for reuse, please contact press@oet.org.

00:10:21 - 20230915T103427Z Note:  associates are crinoids and a basket star, and small anemones
00:11:18 - 20230915T103524Z Note:  another grimpoteuthis sp.
00:13:48 - 20230915T103755Z Note:  there are more sponges in these areas with medium angular rocks
00:16:25 - 20230915T104032Z Note:  another sea star
00:17:10 - 20230915T104116Z Note:  here the terrain once again transitioned to pebble like cobble
00:19:08 - 20230915T104314Z Note:  small brisingids, and in areas of sediment there are imprints where sea stars were resting
00:21:13 - 20230915T104519Z Note:  return to medium sized angular rocks withe bamboo whips and chrysogorgia, glass sponges, flytrap anemone, farriede sponge
00:21:32 - 20230915T104538Z Note:  cluster of pseudoanthomastus
00:27:02 - 20230915T105108Z Note:  possible halosaur unable to get fast ID
00:29:22 - 20230915T105329Z Note:  transition in topography back to pebble field
00:29:44 - 20230915T105350Z Note:  another cutthroat eel
00:30:52 - 20230915T105458Z Note:  fine thin sea star
00:31:33 - 20230915T105540Z Note:  large white sea star, very chunky goniasterid
00:32:08 - 20230915T105615Z Note:  farried_sponge
00:33:10 - 20230915T105716Z Note:  previous sea star was a feeding on a coral
00:40:06 - 20230915T110412Z Note:  area of fine silt and basalt pebble
00:41:16 - 20230915T110523Z Note:  halosaur fish over pebble field
00:42:25 - 20230915T110631Z Note:  holothurian trail marks
00:43:25 - 20230915T110731Z Note:  random large smooth basalt within the pebble field
00:44:19 - 20230915T110825Z Note:  lot of squiggly patterns in the sediment here
00:44:37 - 20230915T110843Z Note:  enchinoderms here seem to be sea stars mainly
00:45:00 - 20230915T110906Z Note:  squiggle patterns may be from bacterial mats
00:45:42 - 20230915T110949Z Note:  a singluar large boulder with sponges on its side, another halosaur
00:47:14 - 20230915T111121Z Note:  there are sea star sediment angles here from where sea stars were feeding in the sediment
00:47:36 - 20230915T111143Z Note:  there are at least 5 prints from sea stars in one frame
00:48:41 - 20230915T111247Z Note:  reapproaching larger angular rocks again, with some glass sponges, farries sponges, brittle stars, a bamboo whip,
00:49:23 - 20230915T111330Z Note:  3 matallogorgias and increase in sponge diversity
00:49:47 - 20230915T111353Z Note:  possible sea urchin just off screen

00:50:21 - 20230915T111427Z Note:  large empty patch of sediment near a pile of rock as if there was something to move it
00:51:02 - 20230915T111508Z Note:  reappearance of larger rocks, sponges and corals, Euplectellidae, chrysogorgia
00:51:44 - 20230915T111551Z Note:  small hemicorallium, first seen in a long time, with a crinoid associate

00:52:15 - 20230915T111622Z Note:  soliaterid sea star
00:53:46 - 20230915T111752Z Note:  there was a brief small patch of sediment that was exposed but did not contain basalt pebbles like the surrounding area, perhaps something moved the rock adjacent to it, there were also small lines within the sediment, too small to be a trawl mark
00:54:04 - 20230915T111811Z Note:  return to basalt pebbles
00:54:29 - 20230915T111836Z Note:  ctenophore

00:58:29 - 20230915T112236Z Note:  there is a large patch of sediment
