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.

01:11:36 - 20230818T055511Z Note:  UTC time 02:00-06:00 Topography alternated beween sandy substrate with many smaller rounded rocks and sheet flow at flatter areas of the dive and larger pillow basalts with little sedimentation at steeper areas. Very intermittent coral with some brisingidae associations present and very few corals (black coral, primnoid, and unbranched bamboo) and very few sponges. Samples collected 101(rock),102(rock), and 103(sea star) were collected. At WP 3 there was large pillow basalt, less sedimentation, and a steeper slope. ROV is having mechanical issues with buoyancy affecting the ability to collect samples. Sample colected 104 (rock). Low biodiversity persists as well as slope. Sample colected 105 (rock). There are the occasional before seen coral and sponges with the addition of sea cucumber, Ramuligorgia militaris, and shrimp. Collected samples 106(rock), 107 (urchin). At the top of the slope, the topography is more sheetflow. Area is for the most part devoid of biodiversity. Sample collected 109 (rock), 110 (rock).
