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.

01:26:57 - 20230814T174552Z Sample: NA153-066 Niskin Area of moderate biodiversity. Cup Coral, black coral, paragorgia, brittle star, and squat lobster present.

01:29:09 - 20230814T174804Z Note:  Munidopsis cf dispar Chirostyloid, Uroptychus on the black coral
01:39:38 - 20230814T175833Z Note:  Watch summary: Inital area of high biodiversity with diverse coral and sponges. Making way from waypoint 3 to 4. Corals were very diverse including, iridigorgia, unbranched and branched primnoids, black coral, Bathypathes, Paragorgia, and cup coral. Others include include squat lobster, sea cucumber, anenome, and brittle star. Transtion from high density coral biodiveristy to lower density unbranched corals getting closer to waypoint 4. Transtion from lower density biodiveristy to higher biodiverse area about halfway between waypoint 3 and 4 with before seeen coral and sponges, now icluding silblogorgia, and metalogorgia. Topography transitioned from pillow basalt, lobe flow, sheet flow, amd tallus slope, back to sheet flow. At waypoiint 4 moving towards 5, similar high biodiveristy was found as was present at beginning of dive.
01:43:12 - 20230814T180207Z Note:  Continuously moving towards WP4
01:47:19 - 20230814T180614Z Note:  Diverse rock: Bathepathes, primnoids, yellow zoanthids colonizing a branching bamboo? or paragorgia coral
01:49:04 - 20230814T180759Z Note:  700m to WP5 (the last WP)
01:52:10 - 20230814T181105Z Note:  N side of seamount rock features were more botryodal. S side seems fresher - perhaps sheet flows fell away or mass wasted away (potential for better rock samples)
