Date: 06/12/2023

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.

00:52:43 - 20230806T140032Z Note:  Passed through low biology area in deeper zone of seamount, site steadily became more diverse with several morphologies of sponges, some Hemicorallium, small black corals. 3 bio samples, 1 geo sample taken. Most rocks that we tried to sample were attached/contiguous to the rest of the substrate. Current speed picked up as we ascended, and we ended shift on top of a highly diverse knoll with multiple species of sponge and corals. Last task was sampling a Parantipathes colony, NA153-007. Need to collect Niskin water sample for eDNA at present location before moving on.
