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.

00:00:14 - 20230916T221252Z Note:  note scientists want grafana on view screens
00:00:47 - 20230916T221325Z Note:  single whip coral, zoom needed to confirm if it is a bamboo coral or primnoid
00:02:04 - 20230916T221442Z Note:  farried sponge with yellow crinoid in area of broken basal, there are also few corals as we move past waypoint 7 we have seen a drop in oxygen and increase in temperature
00:02:48 - 20230916T221525Z Note:  not much density of life here, occasional bamboo coral, and eupectellidae sponge
00:06:06 - 20230916T221844Z Note:  first large boulder outcrop seen on this watch, on the side of this feature there is a bathypathes, and bright orange leopathes, on the top most portion of this feature there is a walteria sponge
00:07:22 - 20230916T222000Z Note:  first leopathes coral seen, sci chat thinks it may be stauropathes
00:09:16 - 20230916T222154Z Sample: NA154-064 ROVGrab Leopathes or stauropthes colony snip, deeper than we may have seen before, bright orange coloration
00:12:45 - 20230916T222523Z Note:  euplectelid sponge, in area with larger boulder rock, also seeing an increase of fan corals in the distance
00:14:54 - 20230916T222732Z Note:  very large walteria sponge with a crinoid associate, on this rock face there is also a cluster of prmnoid fans, a forked bamboo skeleton with a goniasterid sea star feeding on its base.
00:16:52 - 20230916T222929Z Note:  sample collection 064 was a leopathes
00:17:38 - 20230916T223016Z Note:  many cup corals here

00:22:36 - 20230916T223513Z Note:  most diversity seen thus far on this watch, there are mainly calyptrophora corals
00:24:16 - 20230916T223653Z Note:  first chrysogorgia seen in the middle of patch of corals with a crinoid associate, near a bathypathes, and
00:25:22 - 20230916T223800Z Note:  sea urchin in the background with purple body and thin yellow spines, may be a pedinidae
00:25:54 - 20230916T223832Z Note:  beginning to see an increase in diversity
00:29:23 - 20230916T224201Z Note:  large polipopagon sponge, opening on one side much like that of an elephat ear
00:30:20 - 20230916T224258Z Sample: NA154-065 Niskin Fired in area near the potential leopathes and higher diversity of corals, bamboo corals, black corals, polipopagon sponges, primnoids

00:54:31 - 20230916T230708Z Note:  another stalked roselid sponge with 4 "heads" may be caulophacus subgenus
00:56:23 - 20230916T230900Z Note:  correction the last stalked sponge has 5 branches with sponges on each end
