[15:21:15] Although these strata are more friable (fissile perhaps), they may be more likely to hold identifiable fossils for obtaining an age estimate for the substrate beneath the crusts and recent sedimentation. [15:21:17] meganmcculler leaves the room [15:21:30] Although I can't say I see them often on Plumarella. [15:21:56] is it a ring anemone? [15:22:17] There is an interesting question of what comes first: the damage to the coral that creates a space for an anaemone larva to settle, or the settlement and overgrowth of anemone damaging the coral. I suspect both happen in different cases. [15:23:22] irissampaio leaves the room [15:24:24] Regarding the depth that Stephanie is noting: I wondered the same about the carnivorous sponges today.

I equally don't know enough to say it is! [15:27:08] irissampaio leaves the room [15:28:02] My impression is that there is more sedimentation over the coral rubble today than the past few days.

In the Atlantic Bathypalaemonella serratipalma is found on multiple occasions in Chrysogorgia tricaulis and C. averta and C. abludo.

[15:37:51] Goniasterid and bryozoan top right coner [15:38:10] the presence and absence of borings in the adjacent parts of the outcrops is something we are trying to use to evaluate the "age" of the timing of failure along the walls/scarps/cliffs..no borings = young, lots of borings = older [15:38:52] Very cool, @JasonChaytor [15:40:02] Could be the Plinthaster dentatus ChrisM has ID for us around here. But I'm not sure. Lets see what he says. [15:40:09] Plexaurid of some kind...

[15:41:25] Perhaps it was just the angle, but some polyp necks looked distinctly smaller than the anthostele (or calyx) they retract into. [15:41:51] @Leslie By "us" I meant Okeanos! It would be nice to find some natural products from asteroids though! [15:43:03] lophelia [15:43:38] Cladorhizid, trust your pilots, they know better))) [15:43:39] ok, nolan [15:44:12] scottfrance leaves the room [15:44:31] irissampaio leaves the room [15:45:02] increaible geology [15:45:22] LAT : 32.093388 , LON : -77.161238 , DEPTH : 946.2172 m, TEMP : 4.52613 C, SAL : 35.00396 PSU, DO : 7.72729 mg/l [15:45:26] can we zoom at black spots? [15:45:58] The pitting is often caused by dissolution/bioerosion in limestones; looks very similar along this face. [15:46:12] desmophyllum perhaps. [15:47:11] *by bioerosion, I mean more at the microscopic level, not the borings mentioned earlier. [15:47:37] @Tina - yep looks like Desmophyllum [15:48:03] This is the type of habitat we might see Acesta [15:48:07] Bathypathes of some kind [15:48:38] I hoped to that small crinoid that we have off Azores [15:49:55] irissampaio leaves the room [15:50:22] LAT : 32.093346 , LON : -77.161198 , DEPTH : 944.1408 m, TEMP : 4.51484 C, SAL : 35.00455 PSU, DO : 7.72954 mg/l [15:51:08] Just recovering from a computer crash...

[15:53:27] Geodia was before you zoomed in. [15:53:35] @Tina yes, we collected one earlier [15:53:46] Suggested collection target for consideration: this Acanthogorgia with some of the associates [15:53:50] good, thanks megan [15:53:52] Thoughts? [15:54:11] @Nolan and tina - yes, we colleted the bryozoan earlier.

[16:08:50] @Cheryl and @Leslie Asteroschematid ophiuroids are often called snake or serpent stars since that have that smooth tissue covering the rays.

[16:14:44] @Tina: that is what I thought at first, but then I second-guessed myself on the close-up.

[16:15:52] we need microscope :) [16:15:58] lol [16:16:37] @scott, you are kidding, I have this paper in paper version high at the shelf [16:17:29] The grooves remind me of where blood vessels would vascularize the bone. [16:17:38] Maybe a lower jawbone from a toothed whale? [16:18:11] Looks like a large plexaurid fan [16:18:19] big is not black [16:18:31] agree with scott [16:19:40] Paramuricea [16:19:49] agree Plexaurid [16:20:25] LAT : 32.093411 , LON : -77.161344 , DEPTH : 914.138 m, TEMP : 4.48015 C, SAL : 35.00256 PSU, DO : 7.76373 mg/l [16:20:45] do some of those polyps have eggs more proximal towards the skeleton? [16:21:13] i am pretty sure all of the large yellow plexaurids are Paramuricea [16:21:34] (of course there are Acanthogorgia too…) [16:21:41] @scott, yes.. found it.. Fanellia also can be flat and pinnate [16:21:43] @Andrea: agree. But don't ask me for species! Hopefully you'll be resolving that soon. [16:22:12] @Andrea: we did see a yellow Acanthogorgia earlier, but it was quite different from this planar one we just imaged. [16:22:17] @andrea - calices were visible [16:22:59] yes…and we will be collecting more Paramuricea as part of DEEPSEARCH [16:23:13] I am pretty sure those are Plumarella. I have collected them from the area [16:23:17] No.. it is more probable still Plumarella [16:23:23] @Tina: but we wouldn't expect a Fanellia here, would we? [16:23:32] it looks like paragorgia sceleton [16:23:40] And Fanellia has been synonymized with Callogorgia [16:23:41] To me this specimen looked more like an Acanthogorgia but truly different from any specimen I have ever seen [16:23:53] @Scott WOW! That must have been huge! [16:24:45] @megan the expert answered It could well be a Reteporella (there are 2 or 3 other genera that form similar colonies, though), but I've never seen a colony with such a perfect cone shape, usually they are much more curved and bent.

I'm not familiar enough with these primnoid taxa to quickly distinguish them. [16:51:15] are the polyps in whorls? [16:51:22] i would say they are Plumarella [16:51:22] irissampaio leaves the room [16:51:51] Polyps not in whorls [16:51:53] but i didn't get a good look at the polyp arrangement [16:52:03] how about collect this primnoid? looks very common here. [16:52:33] The smaller colonies looked like Plumarella but these are so similar to Callogorgia verticillata [16:52:38] have you collected any of these yet? [16:52:52] That would be okay with me as a representative dominant. [16:53:25] If you have the option and it is easy for pilots, try to collect one that has an associate.
