Channel: Nautilus Live Dive Recordings
Date: 2024-03-11

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.

00:18:52 - 20231023T211950Z Note:  high amount of sedimentation
00:19:25 - 20231023T212023Z Note:  whip coral, farried sponges
00:23:13 - 20231023T212411Z Note:  parimoid coral, mushroom coral

00:26:17 - 20231023T212715Z Note:  bottle brush coral
00:27:14 - 20231023T212812Z Note:  coralid
00:28:17 - 20231023T212914Z Note:  180 degree turn, steep cliff
00:33:30 - 20231023T213427Z Note:  stalked_crinoid
00:33:59 - 20231023T213456Z Note:  red stalked crinoid

00:43:14 - 20231023T214411Z Note:  columnar_formations
00:44:59 - 20231023T214557Z Note:  1-2 meter columnar formations
00:47:14 - 20231023T214811Z Note:  coral
00:47:49 - 20231023T214846Z Note:  bamboo_coral
00:49:51 - 20231023T215048Z Note:  bamboo_corals
00:51:11 - 20231023T215209Z Note:  cookie sea star
00:56:01 - 20231023T215658Z Note:  bamboo_coral
01:01:05 - 20231023T220203Z Note:  watch_change
01:03:48 - 20231023T220445Z Note:  peaked above the cliff along the current feature we are exploring and there are no columnar columns yet, continuing to follow the feature
01:05:05 - 20231023T220603Z Note:  coockie cutter sea star on rock wall near bamboo whip, there is also an anemone in the soft sediment below, heavy sedimentation here
01:06:12 - 20231023T220710Z Note:  no columnar basalt thus far on the dive, continuing to explore to find their location
01:07:23 - 20231023T220820Z Note:  tricolps cameras are all in focus and functional, the cinema cam appears to be lagging or is slightly out of focus, the lighting on starboard cam is darker and less well lit than the port camera
01:08:01 - 20231023T220858Z Note:  continuing along tallus slope until columnar basalt formations are located
01:09:41 - 20231023T221039Z Note:  there is a lens flare in the starboard triclops cam
01:13:44 - 20231023T221442Z Note:  fallen dead farried sponge as we begin to see more angular basalt, curved incatilative basalts
01:14:57 - 20231023T221554Z Note:  beginning to see columnar basalts at 1790m
01:17:38 - 20231023T221835Z Note:  columnar basalts have been found confirmed
01:18:19 - 20231023T221916Z Note:  there is very little life here as the columns are covered in sediment, occasional sponge or coral
01:20:01 - 20231023T222059Z Note:  these columnar basalts are not very tall/high in comparison to those seen in previous dives, triclops ideally will map more high and dramatic terrain
01:22:05 - 20231023T222302Z Note:  I-4 type of bamboo coral resting on the top of columnar basalts
01:24:27 - 20231023T222524Z Note:  the columnar walls we have found thus far appear to flatten out after a few meters
01:25:41 - 20231023T222639Z Note:  as stated in reports from 1996, the wall of interest is east, we are confirming this as our sonar indicated the same.
01:27:22 - 20231023T222819Z Note:  another patch of columnar formations, shorter than those previously seen
