Today’s dive will explore seafloor depths down to 5000 m. It will be the deepest dive of the expedition, and one of the deepest ever to reach the seafloor in this part of the world. We expect to be on the seafloor at ~~11 AST, and remain there until ~~14:00 AST.

We are now on the north side in the better sampled North Atlantic basin, where Umbellula has likely been at least trawl sampled. So, I'm not sure the collection is as critical, although because we know there are multiple clades of YUmbellula, e.g. not all Umbellula will remain classified as Umbellula, every collection that comes with in situ imagery will help us in future better identify them. So, if we don't see other collection targets, then Umbellula would be a good one, in my opinion.

[15:53:53] @Mike: perhaps I can add an annotation. [15:56:13] colorless amphipod makes adaptive sense at this great depth lacking ambient light and generally with luminescent organisms rather scarce. Melanin take energy to produce. Being black at this depth is not necessarily useful.

[16:09:16] @Steve: can you translate the time Mike V has indicated (4:36:36/6:00:00) into the UTC time I'm looking at on SeaTube. i.e. what was approximate time on bottom in UTC?

[16:15:01] Cladorhizid might be in the genus Asbestopluma [16:16:09] given that the bedding in each of these outcrops is at a different orientation, I would say they are displaced blocks [16:16:23] look for me as Hydroids [16:16:44] @jason please let us know if there is some rocks worth collecting [16:17:21] @stacey...is the roof rack attached to D2?

[16:34:02] @Tina I trust you tina :) [16:35:51] The colony we collected in the Hadal hole in PIPA was also Abyssopathes lyra. This is identical to that, but bigger. [16:35:54] Whole!!! [16:36:07] it is not brittle [16:36:26] you have to cut it, close to base you can [16:36:37] do not pull it [16:37:07] otherwise you will strip the tissue [16:37:24] I see the NMNH has only 3 specimens os A. lyra from N Atl, all from 1970s, and all significantly deeper than this one.

Small crustaceans would have very little chance of escaping. [17:46:06] I wonder if it was some kind of anemone that was grazed by something else [17:47:02] @Tara Good idea. I was thinking sponge, but we have not seen any dead sponges that would make that sort of base. [17:48:27] @Nolan sponge is another good idea, especially for some of the more irregular shaped "lesions" [17:49:34] LAT : 19.279279 , LON : -67.681766 , DEPTH : 4908.9887 m, TEMP : 2.2319 C, SAL : 34.86874 PSU, DO : 7.75772 mg/l [17:50:27] @Tara I think anemone may be more likely. If the sponges were dying and falling off the rocks, I would think we would see them, even if they were slightly buried in the sediment. And they probably would be large sponges too.
