Date: 11/03/2024

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.

00:06:05 - 20230914T123011Z Note:  light pink axis coral with darker polyps, possibly hemicorallium
00:08:30 - 20230914T123236Z Note:  some of the bamboo corals here have a lot of yellow coloration
00:10:04 - 20230914T123410Z Note:  very large primnoid colony with a squat lobster associate
00:10:26 - 20230914T123432Z Note:  large ophicanthidae crimson red brittle stars
00:10:50 - 20230914T123456Z Note:  return of high diversity
00:17:07 - 20230914T124113Z Note:  preparing to collect snip of large primnoid with fine polyps and a squat lobster associate
00:22:23 - 20230914T124630Z Sample: NA154-044 ROVGrab Parastenella or paracalyptrophora primnoid snip
00:25:46 - 20230914T124953Z Note:  more Euretidae sponges
00:28:44 - 20230914T125251Z Note:  zooanthids over growing the bamboo coral skeleton causing the skeleton to be yellow even in areas where the zooanthids arent present, some broken portion of the skeleton was chipped away revealing an internal white color
00:30:07 - 20230914T125414Z Note:  another bamboo coral with some very yellow branches, but no zooanthids present
00:31:11 - 20230914T125518Z Note:  there are also hydrozoans behind this bamboo skeleton with some yellow/orange zooanthids
00:32:21 - 20230914T125628Z Note:  we are also seeing some white zooanthids growing on bamboo corals that also have two Solenogasters
00:34:21 - 20230914T125828Z Note:  in this area where bamboo skeletons are crossing over one another, one is partially dominated by yellow/orange zooanthids and the other with white zooanthids, the yellow coloration seems to be from the zoanthids as the yellow color stops when the zooanthid color changes to white/pink
00:36:46 - 20230914T130053Z Note:  large face with high density and diversity of primnoids and bamboo corals reappearing
00:37:23 - 20230914T130130Z Note:  saccocalyx_sponge
00:38:13 - 20230914T130219Z Note:  Solenogasters seen earlier may have been feeding on the zooanthids on the bamboo coral
00:39:47 - 20230914T130353Z Note:  yellowish bamboo corals may be eknomisis
00:43:02 - 20230914T130708Z Note:  we are beginning to see some dead bamboo skeletons
00:44:33 - 20230914T130840Z Note:  note once again we observe the bamboo corals able to dominate the top flat portions of boulder/rock cliffs whereas the primnoids and hemicoralliums dominated the edges, not settling on the top
00:48:07 - 20230914T131213Z Note:  different ecosystem seen from just a few meters away, possibly because of rock formations
00:49:35 - 20230914T131341Z Note:  biologist describes that depth might affect the colors seen in corals
00:51:03 - 20230914T131509Z Note:  continuing to see primoids and bamboo corals with a barrel sponge in view that we have not seen recently
00:52:45 - 20230914T131651Z Note:  red primnoid fan
00:53:04 - 20230914T131711Z Note:  vertical stack geology from dike geology
00:55:48 - 20230914T131954Z Note:  continuing to move vertically up large cliff protusions
00:56:05 - 20230914T132011Z Note:  corals observed only on one side of rock
00:57:22 - 20230914T132129Z Note:  stalked_sponge
00:58:29 - 20230914T132235Z Note:  grid like geology observed
00:59:18 - 20230914T132324Z Note:  bactryoidal texture observed in the rocks
00:59:40 - 20230914T132347Z Note:  big_sacclocalyx
01:00:22 - 20230914T132428Z Note:  pseudoanthomatus
01:02:04 - 20230914T132611Z Note:  hans and upasana discuss geology of intrusive v extrusive
01:03:07 - 20230914T132714Z Note:  bamboo coral with squat lobsters on
01:04:01 - 20230914T132807Z Note:  damaged saccocalyx? and stalk
01:04:17 - 20230914T132824Z Note:  chrysogorgia
01:05:06 - 20230914T132913Z Note:  euplectellids, hemicorallium and bamboo coral continue to dominate
01:08:11 - 20230914T133217Z Note:  saccocalyx, brasingids, and bamboo coral with some primnoids on both sides
01:09:08 - 20230914T133314Z Note:  large fans along rock
01:09:42 - 20230914T133348Z Note:  red shrimp next to bamboo corals
