[15:27:29] The difficulty with the cerianthid collection is that they retract rapidly into their tubes.

[15:27:56] @Les: sure. This might then be the deepest S1 record. [15:28:01] what is size? [15:28:41] Although this looks like pavement, it must be sediment because that anemone has to be longer than what we are seeing. [15:28:50] Or...? [15:28:53] ok, this one can go) [15:28:58] Sure looks like pavement.

[15:29:20] its sitting on the rock I think [15:29:25] it is mystery now. [15:29:33] They are setting up to collect now....based on previous talks about this [15:29:36] I bet for the rock [15:29:38] Perhaps I'm being fooled and it isn't embedded. [15:30:02] They are going to use the suction hose [15:30:17] If that is the case, then a scrape with the suction could work. Will be very interesting to see response. [15:30:32] this cerianthid is full of ambiguities [15:30:47] It is all "head" and no body.

[15:33:59] little bit of sediment there [15:34:11] But I definitely learned something new about cerianthids today!

[15:35:10] vondawarehamhayes leaves the room [15:35:20] Rhian. it will shed tentacles. put some tentacles in alcohol, but body better to have in formol [15:35:41] that was beautiful... it is the cerianthid version of the rock sea pen. [15:35:43] Perfect - 4% with change to 70% etoh? [15:35:56] and normally they are very muscular, so better to eject some formol inside via mouth [15:36:01] @Les: yes!

[15:59:35] do not worry, I hope they are all the same, can we just have close up of one of these later [15:59:59] Sorry - tough to watch the video, narrate, and read the chat! [16:00:06] vondawarehamhayes leaves the room [16:00:06] is it bleached-kelp sponge? [16:00:26] Petrified bleached kelp sponge! [16:00:53] yea, I forgot petrified!

[16:05:58] ask for coffinfish? [16:06:09] I haven't seen any fish [16:07:04] A few decades ago I sampled some glass sponges at modest depths of 300-500 m in the Gulf of Mexico and ran stable C N and S isotope analyses of prepared tissue. The stable isotope signatures proved to be very unusual, suggesting that what was fed upon were probably very refractory, resuspended, reworked particles, several trophic levels removed from the rain of surface planktonThese few samples displayed [16:07:34] LAT : 36.930138 , LON : -58.858354 , DEPTH : 3425.5032 m, TEMP : 2.57073 C, SAL : 34.91205 PSU, DO : 8.0946 mg/l [16:07:47] amphipodish [16:08:49] Actually, 3000 m depth horizon is a good one for a diversity of benthopelagic fishes - however rock habitat is not. Yesterday, the habitat presented much more extensive areas of accumulated sediment - much more friendly to fishes in terms of infaunal and macrofaunal epifaunal prey. [16:09:16] a branched Bathygorgia? [16:09:56] this one cerianthid in the hole [16:10:05] @Les: beats me. Definitely nodal branching. I can't see any needles. [16:10:28] @Les: would that be the first time we've seen a Bathygorgia branching? [16:10:39] yes [16:10:49] you wish sampling of bamboo? [16:10:54] polyp looked to have all small rods [16:11:05] @Les: don't know if you heard me suggest this may be similar to the "candelabrum" we collected yesterday. Will need to look at the close-ups of those polyps [16:11:08] but hard to tell [16:11:26] a short candelabrum, that would be interesting [16:11:56] The good news is that I have seen several of these colonies this morning, so I expect we'll have opportunity to sample if conditions allow. [16:12:30] would be good if the close ups could be just a bit closer to give more detail, and tone down the light a little [16:12:35] LAT : 36.929491 , LON : -58.857851 , DEPTH : 3421.3026 m, TEMP : 2.56841 C, SAL : 34.91274 PSU, DO : 8.05526 mg/l [16:13:00] OK, bring out the fish-whisperers. What we should encounter at ~~3000 m is the large macrourid Coryphaenoides armatus, the rock-hugging cusk eel Diplacanthopoma, the large synaphobranchid eel Synaphobranchus brevidorsalis, the large tripodfish Bathypterois grallator, the eerie translucent lizardfish with yellow eyes, Bathysaurus mollis - and others [16:14:04] that's a perfect shot! [16:14:34] if the basal part of the polyp is "clear" then it means that either scales are present of there are no sclerites [16:14:45] haroldcarlson leaves the room [16:17:34] LAT : 36.930167 , LON : -58.858277 , DEPTH : 3421.3579 m, TEMP : 2.56744 C, SAL : 34.91166 PSU, DO : 8.10565 mg/l [16:18:04] a fully grown one... [16:20:42] I think this will be the deepest collection of a bamboo coral of this type that I have been involved with. Will check my database to verify. [16:21:37] noellehelder leaves the room [16:21:53] vondawarehamhayes leaves the room [16:21:54] At this depth horizon, fishes tend to be either very large (opportunistic omnivorous cruising predators/scavengers) or exceptionally small benthic (sedentary microvores). The diverse middle-sized species drop out at these depths where nektonic prey is scarce. [16:22:07] What is the depth max for bamboo? [16:22:23] Beautiful clipping! Masterfully done.

D2 collected a J-clade from 4302 m on Subducting Guyot 2, North Pacific Ocean in 2016 (forgot about that one!) and another from 3915 m at another seamount in the west Pacific in 2016. So now I am even more convinced it is a "Jasonisis" type, and that that genus will give Bathygorgia a run for its money in terms of depth max for isidids. Still, no collections below 2907 m in the Atlantic, so that was valuable.

[16:33:24] And, at least a part of Bathygorgia might have to go back onto the synonymy list [16:34:52] this one may swim...at least looks like [16:35:03] Eumilidae [16:35:51] gastropod name. if I spell right, and they are eating sexual products [16:36:37] Little scale worm, I think [16:37:12] Maybe a tomopterid worm taking a rest!

No sponge experts today (Chris K has been on earlier dives), though Vonda has been offering IDs of things they've seen to the north. [16:56:35] @Tina: would be best to use the time stamp you see in SeaTube [16:56:43] @Les - that whip has passed - we're not full, but we only have until 2:45 to dive today, as we are so deep [16:56:47] @Tina: I can get it for you if you can't [16:56:58] I tried to call Joana, but she is out of reach( [16:57:13] elizabethfraser leaves the room [16:57:32] @Scott Its good to be back!
