[15:02:45] @Scott, perhaps we should try to collect one of those structures [15:02:48] Have at least one or two nice collections [15:02:53] they are really unusual [15:03:17] LAT : 38.755853 , LON : -30.46186 , DEPTH : 1753.6096 m, TEMP : 4.6391 C, SAL : 35.02707 PSU, DO : 7.7322 mg/l, TURBIDITY : 0.9585 FTU [15:03:20] they look like something fossilised [15:03:41] @Joana: if yo think useful. We are trying VERY hard to reach the ridge crest where we hope the community will be more visually interesting. [15:03:49] Victorogorgia? something purple [15:04:08] @Asako ah! of course! This week has been crazy busy for me so of course there have been bryozoans :) [15:04:18] now we can see byozoan [15:04:29] (TIna) and blue sponge [15:05:00] yes!

[15:10:20] yes, too [15:11:00] Not a good posiiton for ROV. Check out camera 2 and you'll see how steep the wall is. Hard to get stable for collecting.

[15:13:58] @Megan 1910m 3hr less ago [15:14:11] wow ok I see it [15:14:15] Also, thought about you the other day, maybe 3 dives ago, there were bryozoans all over the place. Can get those on youtube I guess [15:14:18] so pretty! [15:14:35] Yes, we have been seeing it a lot. Had an earlier ID suggested by Manuela. [15:14:40] @Megan and 1916 m. [15:14:43] @Megan, totally agree [15:15:01] My last comment was directed to an earlier one from Joana. [15:15:03] @Les I should be able to get on the ftp site and check out some photos [15:15:10] Hard to keep up on typing and viwing! [15:15:15] is this sub-fossilised coral rubble? [15:15:16] michellescharer leaves the room [15:15:19] Good idea [15:15:42] what we see between the large rocks [15:16:03] Hymedesmia [15:16:03] this blue one! [15:16:12] do you interested in Joana? [15:16:17] @Joana, most likely. We collected a lot of this on our 2005 cruise and the corals were dated anywhere from 15k to 125k years ago [15:17:11] I suspect we were seeing a single shell of Acesta here [15:17:18] @les thanks, that's very interesting! [15:17:19] @Joana: Thenea was what she suggested [15:17:24] the sponge again!

[15:19:13] stepped away from the computer [15:19:24] ok, this is not the most common sponge we've been seeing right? [15:19:54] asakomatsumoto leaves the room [15:20:32] Are the tunicates and bryozoans here indicative of exposure to high currents along steep wall? [15:21:11] cheilostome bryozoan is as low as I can get - I need some more familiarity with deep sea branching species... [15:21:33] deidricdavis leaves the room [15:21:58] nonot that one... the common is a globular highly hyspid with an oscule with a "white sphincter" [15:22:02] Sorry - need to be more specific about sponges! The delay and the fact there are so many and I'm not trained, I don't know what people are asking me to focus on! [15:22:17] we recently received the Southeastern Regional Taxonomic Center Voucher collection which had a number of bryozoans, some I think from deeper water.

I'm just trying to help you on shore so that I get the information as quickly as possible. [15:23:46] Especially if it is collection target.

Uncertain the cause but it appears clear now. Let us know if you see any further degradation in the audio or video.

I also have problem with chat today. [15:29:15] elisabettamenini leaves the room [15:29:19] that one in particular seems to be our Thenea sp. nov. 2 :-) [15:30:07] wow that is a really cool sponge [15:30:34] oh wow, this I never saw live, possibly Hexactinella genus [15:31:45] That sponge is amazing looking. [15:31:56] I agree. Seems unusual. [15:32:14] some corallimorphs in the crack just to the side [15:32:29] yellow one hydrozoan?? [15:32:38] (Tina) probably [15:32:47] allencollins leaves the room [15:32:53] if we could collect this entire structure we will get a really nice assemblage, with several species on it [15:32:54] TIna agree with Corallimorphs [15:33:09] (Tina) it was at least 3 corallimorphs - two tiny and one a bit large [15:33:20] LAT : 38.755884 , LON : -30.462085 , DEPTH : 1724.5183 m, TEMP : 4.62812 C, SAL : 35.02711 PSU, DO : 7.72367 mg/l, TURBIDITY : 0.928 FTU [15:33:21] the small white globular sponges are Sympagella [15:33:32] @Tina, agree. [15:33:39] Will attempt to collect... [15:34:05] Given the nature of our position, we will grab it with manipulator, and then have to carry it for some time... [15:34:22] ...until we find a safe position where we can hydraulically open the collection box [15:34:29] and there's also one small Thenea on the structure (top left) [15:34:33] michellescharer leaves the room [15:35:11] So we may actually have to hold this for a while like a bouquet and hope it doesn't fall apart... [15:35:15] wow, the entire structure is smaller than I thought [15:35:19] But I asked them to take the chance [15:35:40] (Tina) and everything is living at fossilized stalk [15:35:41] christophermah leaves the room [15:35:43] good call @Scott, high risk - high gain [15:35:47] It is hard to judge the scale of the view [15:36:29] nice first grab of bouquet... [15:37:47] We can't access the suction because we are pushed against the wall... [15:37:57] it was a good try, and don't worry too much for the sponge. it will most likely re-attach itself and continue living happily after [15:38:20] LAT : 38.755868 , LON : -30.46207 , DEPTH : 1723.1959 m, TEMP : 4.62285 C, SAL : 35.02625 PSU, DO : 7.71281 mg/l, TURBIDITY : 0.9341 FTU [15:38:26] just cross fingers [15:39:01] alainahebert leaves the room [15:39:12] Joined late in this dive.

And Scott is correct in noting that the family Cyclopteridae is unusual in laying clusters of relatively large benthic eggs. [15:42:23] AnaColaco leaves the room [15:42:45] Last seen fish - large dark cusk-eel of viviparous subfamily Bythitidae = Diplacanthopoma. This is a rock-hugging megapredator. Another fish with unusual reproduction mode in deep sea- a live-bearer. This fish has an enormous gape when the mouth is opened - it is a swallower/inhaler of large prey [15:43:21] LAT : 38.755836 , LON : -30.46207 , DEPTH : 1716.9315 m, TEMP : 4.59255 C, SAL : 35.02863 PSU, DO : 7.71324 mg/l, TURBIDITY : 0.9402 FTU [15:45:20] The sponge fell out of the claw and we are trying to find it. [15:45:23] elisabettamenini leaves the room [15:45:26] this one is a sponge [15:45:36] Thanks Joana. Whew! [15:45:37] The fat-headed, black macrourid with elongated pelvic fin rays, slow drifter = Macrourid Bathygadus - as someone suggested. This is a member of a distinct rattail subfamily Bathygadinae. This is a hover/drifter descending only with pelvic feelers detect prey. Not a sediment feeder - but a swallower of small near-bottom nekton - such as amphipods, isopods, 'shrimpopods' [15:46:15] The gray flat-headed female shark = Apristurus [15:46:34] jeanmarcgagnon leaves the room [15:47:24] ok I might actually be able to ID that one [15:47:27] stand by [15:48:21] LAT : 38.755866 , LON : -30.462181 , DEPTH : 1713.3573 m, TEMP : 4.59288 C, SAL : 35.02189 PSU, DO : 7.70914 mg/l, TURBIDITY : 0.928 FTU [15:48:39] about the previous sponge, it is demosponge, order Poecilosclerid (unfortunately that is as far we can go with many of these encrusting sponges because the majority of species were described from dredged + preserved specimens so we have no ideia what they look when they are alive [15:50:53] Hertwigia falcifera white morph [15:50:58] The silver-white halosaur with pectorals held up and out and long undulatory tail and very noticable scales = genus Halosaurus, either H. guentheri or H. ovenii.
