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.

00:16:25 - 20230815T203116Z Note:  Previous anemone could also be - Actinostolida
00:17:24 - 20230815T203215Z Note:  Roughness of yellow tube leans towards Hormathiidae
00:17:51 - 20230815T203242Z Note:  Poliopogon_sp.
00:18:48 - 20230815T203340Z Note:  Steve confirms Actinostolidae: Those anemones have never been identified but imaged many times. I wouldn't even know where or how to collect them

00:21:07 - 20230815T203558Z Note:  Cusk eels are not proper eels

00:47:52 - 20230815T210243Z Note:  Abundance of Hemicoralliums may be caused by the shallower depth

00:50:37 - 20230815T210528Z Sample: NA153-074 ROVGrab Squat lobster on Chrysogorgia, abludo-like sampled from rocky substrate - Uroptychus sp.
