[16:29:36] briefly [16:30:21] Right, would like a zoom on the lighter colored rock [16:31:07] looks like a sabellaria worm reef [16:31:37] oh very nice! Hymenaster I think [16:31:49] we saw this type of substrrate at Manning seamount [16:31:55] It's shallow enough that those could be vesicles but it's a lot of vesicles for what would be a massive flow front [16:32:03] https://en.wikipedia.org/wiki/Sabellariidae#/media/File:Sandcastle_worm_colony_in_laboratory.jpg [16:32:30] sabellaria worm reefs can be immense - they occur of FLorida, big ones in the Bay of Mont St Michel [16:32:40] I would say it's a carbonate structure based on this zoom. [16:33:06] Isn't this carbonate? [16:33:09] sabellaria are agglutinating....maybe its a serpulid reef if carbonate [16:33:10] georgematsumoto leaves the room [16:33:41] looks carbonate to me... but full of what look like worm holes [16:33:45] LAT : 35.052945 , LON : -48.971672 , DEPTH : 1214.8949 m, TEMP : 4.71575 C, SAL : 35.0212 PSU, DO : 8.10393 mg/l [16:33:49] What are the yellow things? [16:34:17] Sad that Jason has been poking around the sedi looking for carbonate evidence this whole expedition then we dive on this when he's not around :) [16:34:42] Iridogorgia bella? [16:34:49] this one is tiny [16:34:53] CharlesMessing leaves the room [16:35:07] There are multiple species [16:35:12] I. splendens [16:35:25] Really Les? [16:35:27] Thanks! [16:35:32] described in 2007 [16:35:33] supertiny [16:35:54] I thought splendens tissue was browner [16:36:02] carolynruppel leaves the room [16:36:04] good point, Kevin. he got to see all my crusts, and I am staring at his carbonate [16:36:05] coils aren't tight enough for bella, or fontinalis [16:36:23] sometimes @Chris, but also purple or white [16:36:36] Ok thanks. [16:37:41] another oreo [16:37:49] What are the fluffy colonies? [16:37:56] thourella [16:38:00] Are they Thourella? [16:38:03] white - thouarella [16:38:09] Thanks Rhian [16:38:13] reddish.. may be black corals [16:38:26] have not checked yet [16:38:45] LAT : 35.053013 , LON : -48.971537 , DEPTH : 1203.8528 m, TEMP : 4.71366 C, SAL : 35.02209 PSU, DO : 8.10639 mg/l [16:38:52] primnoids [16:39:23] They are primnoids. Narella? something like hawaiiensis? [16:39:48] can we zoom at reddish colony right [16:40:21] Polyps facing down so maybe Narella. Also, that genus is known to have unbranched forms [16:40:26] holothuroid-like feeding tentacle crown extending from rock face [16:40:30] I need to look up the name. We sampled it at Kukenthal and Steve C. described it [16:40:58] and there is reddish one at the right [16:41:02] kimberlygalvez leaves the room [16:41:35] I think it's the same Tina [16:41:38] Parantipathes [16:42:01] christophermah leaves the room [16:42:05] Are they both Parantipathes Tina? [16:42:20] I'm pretty well convinced this is a paleo-reef structure at this point. [16:42:29] rhizn, it is not same as it different branching form [16:42:30] agree :) [16:42:48] that one may be Leiopathes. [16:42:51] maybe we weren't looking at the same - I saw one with the same branching to the right. [16:42:55] crinoid [16:43:16] the small line of bathy overnight showed that it was much more sharp of a feature, so I think that make sense [16:43:16] jasonchaytor leaves the room [16:43:46] LAT : 35.053041 , LON : -48.971581 , DEPTH : 1198.281 m, TEMP : 4.72797 C, SAL : 35.02154 PSU, DO : 8.08637 mg/l [16:43:54] another Parantipathes [16:44:23] Right. And there are some other sharp cliffs on or towards the guyot surface. Nothing looks volcanic from the bathy. I'm wondering if it's old enough to be phosphoritzed. [16:44:27] what is that colony? [16:44:37] can we zoom at these? [16:45:27] plexaurid????? [16:46:01] Amen to that Rhian. weird one [16:46:03] no idea what this is, can we fget a piece? [16:46:21] I would second sampling this [16:47:05] there is another colony up [16:47:12] take the best option [16:47:27] vondawarehamhayes leaves the room [16:47:51] how high is this wall? [16:48:06] I've never seen a white plexaurid, so maybe anthothelid... [16:48:17] Thoughts? [16:48:19] I looked at camera 3 and they are fairly close to top where it flattens out [16:48:23] sometimes the anthothelids grow in dead skeleton of something else [16:48:36] robertcarney leaves the room [16:48:46] LAT : 35.053045 , LON : -48.97159 , DEPTH : 1193.0461 m, TEMP : 4.70731 C, SAL : 35.02109 PSU, DO : 8.08394 mg/l [16:48:49] I don't think the polyps are large enough for anthothelid but really don't know [16:48:56] I think sample the one in the foreground [16:49:00] Sample it? [16:49:01] it may be Elicellidae as well? [16:49:23] interesting idea @Tina [16:49:27] Hmmm, that's an interesting guess Tina [16:49:43] like Nicella? [16:50:17] I mean it is not so deep after all [16:50:26] They're going to collect some [16:50:42] good, it is better then guess))) [16:50:49] fish!

Is that what these species are? [16:55:23] I mean the fluffy colonies, not the one they are sampling [16:56:16] Once collected, could we try getting a look at the polyps? [16:56:19] seems quite ... hard to cut [16:56:46] we can ask rhyan make close up photo [16:56:58] Ship is having technical issues, they are having to reposition D2 [16:57:02] Wow, look at that sponge!

[17:17:12] Nice - I can send you some images when it comes up tonight [17:18:40] @Rhian, could I be included on that email? I suspect it might be an Acanthogorgia.

[17:20:11] we had some macro. it is not [17:20:25] interesting idea @James but when the polyps were contracted they seemed smoothly rounded, which also argues again a plexaurid, I think... but maybe Acantho? [17:20:35] Absolutely Jaymes - can you send me an email - rhian.waller@maine.edu [17:20:37] it has calices [17:20:58] Will do @Rhian! [17:21:02] emilycrum leaves the room [17:21:18] Yeah, calices definitely means its not an Acanthogorgia [17:21:54] Acanthogorgia usually stay as they are [17:22:15] Correct, their polyps are contractile, but not retractile [17:22:48] the polyps of Acanthogorgia can contract a little, but yeah, otherwise look like short versions of the uncontracted polyps [17:23:42] it has to do with the way the sclerites are arranged.

But, without a strong OMZ to pass through or anything, we think we'd see similar things. and the edge is the next most interesting location to see something different [17:33:37] @Tina, thanks for posting the link! I agree, there are a few Nicella species that look very similar, based on the images from Fig. 1 [17:33:42] thanks for that @Tina, that's an excellent candidate. Unfortunately there is only one polyp shot, and that from the end of a branch.

I have some images of Riisea paniculata from the Smithsonian that has branching pattern, etc., like this one had. If so, it will be the first collection of this genus outside of the Caribbean. But certainly possible. [17:51:52] I'm glad we got it before the bow thruster went out! [17:53:25] yeah! Are they going to still try to keep on this dive?

[18:47:58] yeah, that will work for now, but I suspect it is not that. [18:48:11] plexauridae of course [18:48:42] the polyps look like they pull into little holes on the branch... is that right?
