Date: 2023-07-20

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.
