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.

00:00:02 - 20230920T001021Z Sample: NA154-085 ROVGrab bamboo with new sparse branching, 10cm, snip was assc free, but the colony has benthic ctenophore seen with this bamboo typically, as well as a squat lobster
00:07:19 - 20230920T001738Z Note:  pause for gages
00:07:46 - 20230920T001805Z Note:  munidopsidae squat lobster
00:10:51 - 20230920T002110Z Note:  same diversity of species
00:11:42 - 20230920T002201Z Note:  neon yellow staled bolosoma with a nearby bamboo whip fed on by goniasterid
00:12:36 - 20230920T002255Z Note:  another green parasite on the sea star, seen in ID guide as well
00:13:13 - 20230920T002331Z Note:  there are two green parasites on this sea star
00:17:10 - 20230920T002729Z Note:  wavy ruffle shaped sponge may be a rosellisae Lanuginella n. sp
00:20:21 - 20230920T003040Z Note:  nodal branching bamboo coral fan with mysids
00:23:01 - 20230920T003320Z Note:  chaunocops
00:24:02 - 20230920T003420Z Note:  the neon parasites on the sea star were polychete worm
00:26:07 - 20230920T003626Z Note:  chaunocops chased a shrimp that went under the rock
00:28:03 - 20230920T003822Z Note:  curled bamboo coral whip, small increase in stalked bolosoma
00:28:42 - 20230920T003901Z Note:  sea_cucumber
00:30:25 - 20230920T004044Z Note:  55m from waypont 4. and wp5 is 569m away
00:36:06 - 20230920T004625Z Note:  large Amphidiscosida sponge probably a poliopogon type of sponge
00:37:57 - 20230920T004816Z Note:  begining to see a few more crinoids associated with walteria sponges
00:39:35 - 20230920T004954Z Note:  we are seeing many different variations of poliopogon sponges
00:41:33 - 20230920T005152Z Note:  "Y" shaped bamboo corals
00:42:45 - 20230920T005304Z Note:  there is more density and diversity underneath overhangs here
00:43:51 - 20230920T005410Z Note:  stalked bolosoma with larger pore openings
00:45:24 - 20230920T005543Z Note:  another protruding rock face with higher density of biota, possibly due to it being more suspended into the water column
00:47:29 - 20230920T005748Z Note:  first brisingid seen in a long time
00:50:14 - 20230920T010033Z Note:  zoo on protruding rock near waypoint 4 has an increase in diversity, somw shyrsogorgia, hydroids, walteria sponges, primnoid fans
00:51:58 - 20230920T010217Z Note:  there are a lot of hydroids on the underhang of this rock, also some cup corals
00:53:10 - 20230920T010329Z Note:  very large skeleton of a cup coral, thicker than those we have seen
00:54:49 - 20230920T010508Z Note:  not many changes in the species we are seeing
00:55:15 - 20230920T010534Z Note:  a few more chyrsogorgia here than in the last 2 hours

00:59:48 - 20230920T011007Z Note:  parallel with waypoint 4
01:00:37 - 20230920T011056Z Note:  larger poliopogon sponges here where there is a steep wall, suspending sponges over the open water
01:02:22 - 20230920T011241Z Note:  the peak of waypoint 4 looks like compiled sheet flows, fracturing of the flows created 2 cliff faces
