Channel: Nautilus Live Dive Recordings
Date: 20/07/2023

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.

0:01:12 - Note: correction ID is Enypniastes
0:01:42 - Note: sandy bottom with sandy sediment rocks maybe carbonated 
0:04:34 - Note: cool rock features 
0:05:03 - Note: laser divebot is troubleshooting 
0:05:56 - Note: sea anemone 
0:08:06 - Note: crinoid, bamboo coral, chrysigorgia and a bunch of black circles 
0:09:22 - Note: seen some halosaurs and sea cucumbers 
0:12:45 - Note: abluto
0:13:27 - Note: iridogorgia
0:15:16 - Note: Id for first sea start is brisingidae
0:17:42 - Note: many associates on this yellow coral such as anemones, fly trap and brittle stars
0:19:08 - Note: yellow bamboo coral 
0:19:26 - Note: inter nodal 
0:20:15 - Note: going to run a laser test on the yellow fan coral we saw with many associates 
0:22:49 - Note: getting in position firing laser 
0:26:01 - Note: laser test is done 
0:26:58 - Note: got good exposer within laser test therefore means they got good data 
0:27:26 - Note: black coral?
0:29:23 - Note: considering the best position for the ship to go 
0:29:54 - Note: going 20 m at 270 degrees at 0.2 knots 
0:32:51 - Note: mushroom top shaped layered ridge 
0:33:48 - Note: not much seeing much bio 
0:35:22 - Note: shrimp and sea cucumber 
0:36:41 - Note: some kind of caridean shrimp
0:37:09 - Note: nematorcarinid ? for shrimp
0:38:05 - Note: synallactida sea cucumber
0:39:03 - Note: transitioned into sandy substrate 
0:41:59 - Note: going down slope 
0:47:03 - Note: so far we have been traveling along slopes layered ridge not seeing much bio but have seen crinoids, iridogorgia, chrysigorgia, sea stars (brisingidae, and white sea star), enypniastes, shrimp (nematocarcinid), sea cucumbers, and anemones 
0:47:45 - Note: rocks/ boulders has been covered in sandy sediment 
0:48:04 - Note: coral maybe primnoid 
0:56:42 - Note: had to come up a little to get rov and ship in position, heading back down to bottom to travel up slope again
0:59:34 - Note: some type of cusk eel maybe or fish
1:00:59 - Sample: ~50x40x15 cm sandy sediment encrusted rock  (Sample ID: NA149-179) (Sample Type: ROVGrab)
1:02:01 - Note: going to hold position to try and land or grab a rock for divebot to run a laser test 
1:04:24 - Note: got rock sample for laser testing 
1:06:11 - Note: dc gf fault detected again 
1:08:56 - Note: looking for a flat surface to slurp sediment for testing later
1:12:05 - Note: trying to collect sediment 
1:14:47 - Note: arm is the issue for ground fault 
1:19:37 - Note: continuing to scrap/slurp up sediment for laser divebot to be able to test the white sediment underneath 
1:21:39 - Note: testing laser now
1:22:28 - Note: turning off lights to help laser better 
1:28:18 - Note: laser divebot likes to test to on carbonated rocks to really see the organic matter within the rocks, the blue light is showing the minerals within the rock and the green light show the organic matter which is good for data and a good find for their research 
1:31:55 - Note: continuing to run laser test
1:37:45 - Note: on top of white sediment we scrapped laser divebot will be using\ ultralight source that they added as a secrete weapon to see if it helps giving more data
1:38:38 - Note: using UV/laser with herc landed, ~1.5 m off bottom at back of herc
1:43:01 - Note: finished testing seems to be too far and too close 
1:52:35 - Note: carniverous aeginona hydrozoan on primnoid possibly
1:57:56 - Note: sea urchin
