That means lots of time to look around! [21:00:21] kellymarkello leaves the room [21:00:35] Awesome, sounds great. Just caught the tail end of what Brian was saying. I'm not immediately aware of any dives on features like this either, so this is another really unusual and valuable dive [21:00:39] Should be fun!

[21:18:32] chat-admin leaves the room [21:18:44] The big problem with collecting many deep sea animals is the fact that we know so little about intraspecific variation in their morphology. Sponges in particular can have all types of morphological differences since they are responding to a certain extend to depth and current flow. At some point in the future, we will have a much better idea. [21:19:18] samcuellar leaves the room [21:21:00] wow! [21:21:34] Interesting. The crrust isn't batryoidal. [21:21:46] scleractinian at 4366!? [21:21:50] yeah... will want some close ups here? [21:21:57] yes a SCLERACTINIAN [21:22:10] tiny! [21:22:17] Collect cup coral? [21:22:22] don't you collect that scleractinian!? [21:22:30] I vote collection [21:22:32] i think we will asako [21:22:35] sounds good [21:22:38] I would vote yes, collect cup coral [21:22:55] LAT : 27.398322 , LON : 179.869787 , DEPTH : 4364.5948 m, TEMP : 1.46858 C, SAL : 34.68333 PSU, DO : 4.73804 mg/l, TURBIDITY : 0.0549 FTU [21:23:12] oh wow, good close up of the crust here as well. what is this texture Chris K and Val?

[21:24:07] lets see the other one [21:24:08] JohnDeitz leaves the room [21:25:07] we can pass on this I think [21:25:12] we might see a bigger one [21:25:59] i see a row of what looks sorts like them. or maybe just more white specks, but hey! [21:26:25] Chris M, stubby arms just because its young or are they just stubbier in general from the ones we saw in the Marianas and Musicians? [21:27:25] if its a porcellanasterid, then stubby arms are characteristic of the family. [21:27:53] But the 2 in the guide aren't stubby though.

[21:29:26] Ah, I knew I could extract a high res guess from you. Thanks [21:29:35] sort of like this https://x.com/echinoblog/status/455735195791286272 [21:30:08] maybe one of these https://x.com/DiversityMDPI/status/1711666647172518286 [21:30:18] im wondering if here the CCD is deepened? otherwise might suggest heightened food supply, no, to make up for extra energetic expense of calcification? [21:30:34] Gotta it. They sure looked similar to the ones in your link. Thanks [21:30:38] That's the average for the Pacific. Looks like the Atlantic CCD is deeper, closer to 5500 m https://www.sepmstrata.org/page.aspx?pageid=358 [21:30:52] was reading this one https://www.nature.com/articles/s41559-023-02122-9 [21:31:03] pub 2023 but probably relevant enough [21:31:20] yeah, atlantic CCD is deeper, more carb seds (and part of why IODP samples there more) [21:32:16] Thanks, Sara! I actually hadn't realized that the Atlantic CCD is so much deeper. I spend too much time with my head in the Pacific sometimes [21:32:30] Great collection!

[21:34:53] is it me or does one of those round white circles have a movement trace? [21:35:20] ooo chris, is it the one to the left of the central brittle star? [21:35:24] Chris, are you looking at the one on the lower left? [21:35:42] center lower [21:36:00] just passed ove r it [21:36:20] Val, your opinion on the texture of the rock here? Crust looks thick but not batryoidal. [21:37:30] oh neat! [21:37:32] Agreed, Chris. It's much smoother/massive in texture compared to yesterday. Still quite well-developed, which is going to make it a pain to get good material [21:37:37] can we suction?

[21:38:37] we shall see! [21:38:41] Great great view [21:38:57] CHris what would the field ID be? [21:39:01] It is! If we're lucky, we'll find some broken stuff along the track [21:39:02] amazing we could find another scleractinian here [21:39:26] possibly Ophiomyxidae the disk looks soft [21:39:31] and see through [21:39:58] seriously. We should save some of the water for geochem and the seds if we can get them. [21:40:09] we are seeing its guts I think [21:40:13] see if we can nail down omega calcite [21:40:29] If its soft, then can you really call it a "brittle" star? [21:41:38] its movement was its undoing! [21:41:47] D13_04B [21:42:00] oh sure.. arms will still break.. but the disk is soft [21:42:04] Oh yeah - was that tiny sea star successfully recovered yesterday? That was a tricky collection [21:42:13] It was not :( [21:42:22] I looked through the detritus in the jar for 30 mins under the scope... nothing [21:42:26] so sad about that! [21:42:27] I'l bet that's a new species/genus.. [21:42:31] Daww, that's a bummer [21:42:36] oh really? that's too bad. [21:42:40] I know. Just a stupid joke, that's all.

This is the volcano version of taunting scientists [21:45:08] chrysogorgiid [21:45:57] Val, at least you know that millions of years ago, these rocks would have been collectible. We're just a bit late. [21:46:39] Totally, Chris! [21:47:03] I don't suppose you could collect? Its unknown [21:47:15] JohnDeitz leaves the room [21:47:25] Porbably some type of corbitellinae [21:47:41] collecting [21:47:57] LAT : 27.398274 , LON : 179.869718 , DEPTH : 4359.2553 m, TEMP : 1.4681 C, SAL : 34.68362 PSU, DO : 4.95787 mg/l, TURBIDITY : 0.0794 FTU [21:48:01] putting with coral. [21:48:05] Probably won't be anything that's possible to grab along this slope. Eyeballing things, it's well above the angle of repose. Anything loose is likely to have tumbled, and everything else is just glued in place [21:48:19] Any slope breaks and we may be in business for a rock [21:48:27] agree this face is not giving me any good vibes for rocks. [21:48:41] But it has a very weak sieve plate on top covering main osculum [21:48:44] val, would slumps be a target? looks like the slump we just saw was very encrusted [21:49:10] Slumps yes! They could be old and very crusty, but we don't know till we get a good look [21:50:11] Chris K, there's some botryoidal texture on the sides and undersides of the overhanging rocks. Smooth tops. We see this kind of texture come up in dredges sometimes [21:51:02] Some similarity to Saccocalyx sp but it doesn't have a stalk from what I could see. We guess at the id from something somewhat similar from the Musicians but it was never collected. [21:51:11] never mind, not putting with coral! [21:51:23] thank you chris k!
