[12:01:51] In general, our protocol is to sample when it is clear the need, or we have more than one scientist supporting the request.

[12:05:45] Looks like one from yesterday [12:05:53] The orange Paramuricea comes up frequently in the images we have and we still do not have an ID to species level [12:06:25] what fraffy white colony/ [12:06:28] ? [12:06:33] I think of this as the "candy store" dilemma. Four kids go into the candy store where there are lots of candies, but they can each only buy one. But they only know the candies they have seen, they don't know what else the store has. So, how to determine what and when to buy a candy. [12:06:34] Anthothelidae [12:06:44] Thanks Scott!

No thorn scales, etc. [12:16:29] Good point @Scott, but hey.... [12:16:35] emilycrum leaves the room [12:16:48] I vote Plexaurid... [12:16:53] (Tina) I was distracted( [12:17:03] (Tina) but Plexaurid [12:17:33] sclerites will tell the story. great shot of the polyp contracting into the axis.... or retracting I guess we should properly say [12:17:38] LAT : 40.662416 , LON : -29.384695 , DEPTH : 1753.7113 m, TEMP : 4.12026 C, SAL : 34.95996 PSU, DO : 8.14251 mg/l, TURBIDITY : 0.9341 FTU [12:18:25] also, polyps rather large for ellisellid, so I go back to plexaurid [12:18:27] is that deep purple one was what? I missed close up [12:18:51] Paragorgiid [12:19:31] Carlos & Manuela: regarding collection of the Paramuricea. I'm noticing that there are some like the first one we imaged - with the Asteroschema - and some without. That may reflect different sspecies. Our work on NES and Corner Rise showed there are 3 or more so... [12:20:24] starfish eating on a hard coral?? I guess that is what you do when there are no bamboos [12:20:36] (Tina) one Bathypathes, another Parantipathes [12:21:09] or maybe it is eating the soft corals on the old coral skeleton [12:21:13] bryozoan [12:21:38] Swiftia in the back [12:21:53] no sorry, Paragorgia [12:22:26] telmomorato leaves the room [12:22:38] LAT : 40.662469 , LON : -29.384747 , DEPTH : 1755.6402 m, TEMP : 4.09907 C, SAL : 34.97077 PSU, DO : 8.18543 mg/l, TURBIDITY : 0.9219 FTU [12:23:40] neuscampanyallovet leaves the room [12:24:03] Back to Paramuricea: so, tell me which you want, or do I take a chance with any one of them? [12:24:16] need to zoom purple thing in foreground if possible. Victorgorgia or Trchythela? [12:25:05] I think both are there Les. [12:25:11] ok [12:25:15] Next opportunity I will zoom. [12:25:34] I'm getting overwhelemed by how much there is I hardly know where to direct attention! [12:25:51] regarding the Paramuricea, the most abundant, structuring the community ..

Since not very transparent, probably the latter [12:48:21] I think it's a closed polyp [12:48:57] We can sample the dead coral with black crust if there is any interest in possible manganese precipation.

We should close up on some different colors - both solenosmillia and lophelia can occur in different colors sadly, so it's hard to tell without looking at polyps.

Just back from lunch and I saw earlier comment "large orange Paramuricea" is the one you want to collect. I think I know the one you mean - it lacks the Asteroschema. [14:39:51] Scott - regarding the lateral line canals on the head of the Chimaera. In elasmobranchs generally, the underside of the snout (sharks) and flanks of the head are peppered with tiny pits containing modified lateral line organs - electroreceptors called Ampullae of Lorenzini. Chimaeras have these all over the head, and also along those lateral line canals on the head. These are fishes with a varied diet - but they are specifically adapted with parrot like jaws to crush mollusks and other hard shelled inverts - probably located using electroreception. Benthos feeding skates and rays do the same. [14:41:15] Hi Scott, yes that one.. just because is very abundant, large... strutural spp [14:41:26] Thanks Ken [14:41:38] Okay Manuela [14:42:11] The chimaera is in the genus Hydrolagus [14:42:35] (Tina) Neogastropod my guess [14:42:55] LAT : 40.662649 , LON : -29.385759 , DEPTH : 1711.003 m, TEMP : 4.15112 C, SAL : 34.97506 PSU, DO : 8.0946 mg/l, TURBIDITY : 0.928 FTU [14:43:08] (Tina) it just jumped down, snail I mean.

This balances the electric field to the left and right - such that any deviations (from prey emitting charged ions physiologically) show up as distortions of the field. Chimaeras tend to swim holding the trunk and tail very straight - except when turning, using flapping of the wing-like pectoral fins for locomotion instead of the tail [14:48:33] monikaneufeld leaves the room [14:49:11] oph or star i that sponge??

Thanks! [15:03:39] Successful collection [15:05:10] Hi Scott, I've been taking ocasional peeks on the video during the meetings and I see a lot of hexactinellids that would be worth collecting. For some (but rather few) I have an idea of species/genus but for many I do not. Note that most descriptions of these species for the area are from the early 1900s on dredged material, so being able to do proper taxonomy (+ genetics) on those and match them with original descriptions would be an incredible contribution to the field. [15:06:08] The slow-drifting silver-blue fish that looks like a shallow-water butterflyfish is Neocyttus helgae, the false boarfish, family Oreosomatidae, more generally called Oreos. Some species off Australia and South Africa get large and are fished commercially. The mouth looks small but is highly protrusible. Oreos are associated with deep reefs and rocky dropoffs. Feed on small inverts, and I suspect they also nip coral polyps, having seen them nipping at soft coral branches. But that may just be to dislodge amphipods, etc..
