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.

01:36:23 - 20230816T055114Z Note:  Watch Summary: Started out in a steep slope continued upwards towards summit and way point 6. Topography is large boulders and occasional areas of smaller rocks and sediment. Generally sparse biodiversity with some clusters of mushroom coral, iridigorgia, chrysogorgid, bamboo coral, Paramuriceid, and vicotgorgia (at higher depth 1600m then initial start 1700m), and sponges. There are coral bases on peaks of topography that indicate they have had past colonies. As tracking increases topography morphs. Bottom gets less steep and there are more areas of smaller rocks next to larger broken and unbroken pillow basalt, as well as more sediment. At the shallower depth is reached, more biodiversity is present, not many sponges. There is more marine snow in the water column. Anemones, squat lobster, before noted coral including black coral, Paramuriceid with ophiurida associates, present. Some sea pens present. Collected samples 084-086. Witnessed 2 Grimpoteuthis. As ridge is reached biodiversity declines with steeper topography and stronger current. Reached waypoint 7.
