Channel: Nautilus Live Dive Recordings
Date: 2023-12-06

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. 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.

00:40:50 - 20230823T064938Z Note:  Substrate has changes to basalt pillow with a sharp edged drop off
00:41:14 - 20230823T065002Z Note:  Lava tube in view
00:41:35 - 20230823T065022Z Note:  Sheet flow overhangs
00:43:40 - 20230823T065228Z Note:  Chrysogorgiidae and Bamboo corals in view
00:44:40 - 20230823T065327Z Note:  Zooming on biology

00:53:48 - 20230823T070235Z Note:  Chrysogorsia
00:54:18 - 20230823T070305Z Note:  Sparse, small biology and spongy debris. Mainly primnoids
00:54:34 - 20230823T070321Z Note:  Atop large boulder formation
00:55:31 - 20230823T070418Z Note:  Calyptophora_sp.
00:55:59 - 20230823T070446Z Note:  Could be an intrusive flow that went up along the the crack. Resembles a wall
