Channel: Nautilus Live Dive Recordings
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 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. Please note that the YouTube videos may be incomplete and are not the full-resolution video. For press inquiries or licensing requests for reuse, please contact press@oet.org.

0:02:19 - Note: dropping vehicle lower for some tighter shots
0:08:44 - Note: noting that now that we've been using laser, bottle is warming up slightly. this will help keep bottle warm in the future dives
0:11:50 - Note: seeing a few small red shrimp
