[15:17:22] If it has a sieve plate, it is Euplectellidae, possibly related to Regadrella.

[15:30:24] Yup - can see the hydroid polyps extending from the skeleton [15:30:35] Steve, was Crypthelia collected during EX1605? [15:30:50] I need to revisit my hydrocoral anatomy. [15:31:15] We collected Crypthelia during this expedition. I can't speak to 1605. Do you mean EX1502? There were no collection on that expedition. [15:32:04] I meant this: https://www.ncddc.noaa.gov/okeanos-animal-guide/HydrozoaCoral-like013.html [15:34:40] LAT : 17.772778 , LON : -65.427486 , DEPTH : 2083.7064 m, TEMP : 3.83892 C, SAL : 34.97214 PSU, DO : 7.80345 mg/l [15:36:09] @Steve: for more context on the bamboo corals around here, on our 2009 Bahamas expedition (Abaco Canyon through Bahamas Escarpment and inner slopes) we were amazed to find a dozen or so different isidid species, when only 4 had previously been recorded. There were 2 or 3 that had thin skeletons, including Cladarisis and the unbranched Lepidisis caryophyllia (the type for the genus). [15:36:33] Pleurochorium in Euritidae [15:36:50] It seems their habit of living tucked on jagged walls and their brittle ness made them hard to collect with trawls or nets. [15:37:03] @enrique That one looks distinct. I don't recall if it was collected. The one we saw today was planar and this one in the photo is quite 3Dimensional [15:38:51] Maybe hydroid?

So I am not really surprised by this one being covered in sargassum [15:40:58] Encrusting sponge. Its so hard to ID these without collecting.

[15:46:18] stalked crinoids looked like Conocrinus for me - has to be something close by [15:47:25] if somebody have seen ascidians like this?? [15:47:34] side view of sponge...

[15:51:24] This isidid lacks prominent spines between tentacles... [15:51:42] agree with collection of tunicaate. [15:52:03] We have collected the solitary stalked tunicates, but not to my recollection a colonial form, and definitely not anything that looked like that last beast.

[15:55:42] never I would tell, I have never seen tunicates like this [15:55:52] This looks much more like a tunicate now. [15:56:04] I am in favor of a collection. This is novel for sure [15:56:08] @scott, they slurp them with some success [15:56:15] we are collecting, OK? [15:56:22] Yes, this is a good angle to see it is a colonial tunicate. [15:56:29] Yes, please collect. [15:56:42] probably mushy [15:56:53] Snip at base.

[16:20:44] because it is grey and with five arms [16:21:45] The Paragorgia species did tend to be shallower (not more than 1600 m I think) [16:22:00] and we would want any rock with bio to go into the bio box? max rock size would be 10cm or so [16:23:19] and very important thing in stalcked crinoids are arms. and in trawls and dradges arma are generally gone [16:24:02] Would the stalked crinoid warrant a collection of its own?

Then all you have to do is enter the correct numbers into the name. And to help with maintaining the correct times linking SeaScribe to the video, you can also manually edit the times when you are creating the observation (this means you can retroactively add the accurate start/end time for the collection).

I was working on completing the processing of the images from the samples yesterday. Yes, I have it in the database as a geo sample. I just notated it in Seatube as the associates were part of the reason for the interest in that collection. So if someone were looking for that specimen, they could also look here. Thanks for the suggestions. Also, I'm working in Seatube v2 which doesn't have the operations options. I can edit the times in v2. However, after the cruise, I will go back and correct all the seatube annotations of the samples as I've run into some difficulties with this roll out. [17:22:36] can we collect it? [17:24:23] We have only one box left for the dive. Only a couple hours left on bottom. If there is strong consensus we can collect but we might risk not being able to meet our dive objectives [17:24:49] @MeganCromwell No worries! I just wanted to pass on some of the things that I learned as sample data manager. I didn't know that Seatube had been upgraded.

[17:25:13] kevinrademacher leaves the room [17:25:26] I appreciate it Nolan! #teamwork [17:26:03] it is a sponge that we apparently have at MAR in both clam zones and nobody collected [17:26:11] Frilly branched sponge looks like a hexactinellid [17:26:38] @Megan Absolutely! [17:26:55] Got it. I don't think we've collected any sponges so far on the expedition, have we? [17:27:09] @scott, I mean in French and Russian [17:27:16] @Steve that frilly one is Tretopleura [17:27:22] No [17:27:27] more whip corals, perhaps primnoids [17:28:03] @nolan, for some reason my colleague Kostya Tabachnick rejected it to be hexactinellida [17:29:52] LAT : 17.773136 , LON : -65.426765 , DEPTH : 2005.7175 m, TEMP : 3.82139 C, SAL : 34.97162 PSU, DO : 7.79062 mg/l [17:30:50] @Tina I am pretty sure it is a glass sponge. I remember Chris K talking about this and there are at least very similar ones like it in the animal guide, in the genus tretopleura [17:31:08] I will send him screenshots to be sure though. [17:32:14] Nice view of the hooked rear walking legs of the chyrostylid adaptations to hang on to colony. [17:33:18] briankennedy leaves the room [17:33:59] @nolan. it is reason I was surprised. [17:34:25] Any chance of zooming in on one of these little stalked crinoids? I might be able to get it to family. [17:34:40] we are looking now from other side [17:34:54] @Tina Can you ask why Kostya thinks that, please?

They seem to be on the crust as well as the lighter rocky substrate [17:39:53] LAT : 17.773054 , LON : -65.426629 , DEPTH : 1990.0783 m, TEMP : 3.81913 C, SAL : 34.97091 PSU, DO : 7.78495 mg/l [17:41:07] We have just reached the viscinity of WP 2. Obviously the terrain has slowed us down a bit. Off bottom is at 3:30 local and its 20 minutes to 2pm. There is a slim chance we'll make it to the summit here but we will try to make as much way as possible. [17:41:18] Heterorete glass sponge [17:42:08] @Steve I have an answer to one of your questions about the branching stalked sponge earlier. When tissue of glass sponges die, the spicules remain. Those spicules catch marine snow and that is indicated by the discoloration. If the tissue of the sponge were alive, it would clear of the debris or injest it. [17:43:01] @Nolan thanks for the clarification. [17:43:17] @Steve You're welcome! [17:43:42] It was a good question.

Thanks. [17:47:05] Glad I did not sign off yet. [17:49:33] It likely has 10 arms - 5 rays at the base that branch once each. I cannot quite tell if this is a septocrinid or bathycrinid. It looks different than anything I have ever seen in the W Atlantic.

[17:51:41] @thanks charles [17:53:30] scottfrance leaves the room [17:54:19] If you see another crinoid like that, please collect. I might be new. The only roughly similar species with 10 arms have been collected in less than 1000 m and more than 4000 m. [17:54:43] @charles will do [17:54:57] These little 5-armed crinoids look like bourgueticrinids, but they usually "root" in sediment.

[18:05:42] @Steve: no problem, don't go back. There are many different species of unbranched bamboo corals, so the only way to distinguish them is at polyp scale. But we aren't going to stop and closely image every one. [18:05:58] Chris M will be excited! [18:06:08] Soon I will be able to get back on the phone and so be able to make the requests in a more timely manner. [18:06:18] We observed that these eat glass sponges!

[18:13:44] Many of the small, flexible, brown, branching organisms (that you might think were algae in shallow water) appear to be agglutinating foraminiferans. They can be hugely abundant. [18:14:16] Wow! That means my full-res feed is on a 30 sec delay. [18:14:22] @charles are you talking about the bushy-looking brown branching things?

Over the past several expeditions I've had <4 sec delay, which is why I am so surprised at this delay.

[18:21:03] I agree Daniel, but you are a little off on spelling: Sibogagorgia cauliflora, named for Siboga Expedition [18:21:21] The passing glances of the little 5-armed stalked crinoids suggest Democrinus. There are 3-4 named species, but it is not clear how many are valid. [18:21:37] Thanks Scott [18:22:37] Can we zoom on large fan please? [18:22:52] @iscwatch: clearing cahe did not help.
