[03:12:05] kaseycantwell leaves the room [11:54:08] EX1806 DIVE04 Test message [11:54:28] chat-admin leaves the room [12:16:22] EX1806_DIVE04 ROV Launch [12:24:26] EX1806_DIVE04 ROV on Surface [12:24:30] EX1806_DIVE04 ROV Descending [12:38:28] Morning all - we are on station, weather looks good, and we are enroute to the seafloor! [12:41:54] bring on those jellies! [12:47:58] morning Dhugal! [13:01:32] kaseycantwell leaves the room [13:01:46] taraluke leaves the room [13:01:56] test [13:02:07] me too [13:04:10] working fine [13:07:38] taraluke leaves the room [13:08:10] Good morning all. [13:08:34] I'm not on the telecon, but I'm listening [13:09:13] Kate Rose, not on the call but annotating geology on the video for the corals program [13:14:14] lost video briefly. back now. [13:17:43] cherylmorrison leaves the room [13:21:53] dhugallindsay leaves the room [13:23:32] thanks Kate! [13:23:55] are you guys seeing the CTD- very odd [13:27:35] very [13:28:26] EX1806_DIVE04 ROV on Bottom [13:29:15] Hello all [13:29:49] Hello Asako. [13:29:58] Hi Tara [13:30:20] kaseycantwell leaves the room [13:30:50] Good morning and Happy Fathers Day to all the Dads out there! Looking forward to todays dive! [13:32:00] Good morning! [13:37:07] katerose leaves the room: Replaced by new connection [13:37:15] Ideas of what this yellow organism is? [13:38:17] Stichpathes black coral [13:38:31] This color is not uncommon [13:46:01] I see Stauropathes. There is also Bathypathes [13:46:14] This one is Bathypathes [13:46:24] Bathypathes is on the ASPIRE connectivity list. [13:46:37] Stauropathes is not, in case that factors into collection. [13:46:42] decsison [13:47:05] Polychaete worm on this Bathypathes - a typical association [13:47:33] Stauropathes on right, Bathyp[athes left [13:47:54] Another Bathypathes behind thos Stauropathes [13:49:11] Good eye Cheryl - a stoloniferan, possibly Cornulariidae [13:49:28] We've made lots of collections of both of these from New England Seamounts, but I'm not familiar with collectionds from down here. [13:49:46] Should we collect one of each? [13:50:05] We were not permitted to collect black corals on our Bahamas Escarpment dives as we lacked CITES permits [13:50:57] This is a good opportunity! [13:51:11] I don't know enough about collection history of these, so I'm neutral. Feel free to collect if there is a request. [13:52:18] if you ask me, I basically agree with coral collection :) [13:52:42] I agree with what Peter just said [13:53:35] Stauropathes less common in sightings than Stauropathes [13:53:48] I mean "than Bathypathes" [13:54:05] you confused me Scott! [13:54:18] Sorry! [13:54:28] Too early for me to be typing fast [13:54:34] Haven't had my coffee yet. [13:55:29] you maybe enjoying your father's day? too early to have wine? [13:56:25] Be haha [13:57:42] Note: the Bathypathes often have a scale worm associate tucked in to the polyps on the main axis, so check that out. The Bathypathes we imaged before we moved to these two colonies had one of those scale worms. [14:01:54] If no one else is making a notation of the collection in SeaScribe, please type the specimen numbers here and I will add them. [14:03:31] we collected both? my video has a lot of delay today. [14:03:47] For the Bathypathes on the right, there is definitely a polychate, so try clipping below it. [14:04:01] Still collecting Asako. [14:04:15] thank you Scott. [14:07:35] Eel swimming away was not a Conger eel. Telltale end of caudal held above the horizontal axis of the body when swimming = Synaphobranchus. Conger per se unlikely at this depth although other congrid genera do occur below 1000m [14:08:34] lesliesautter leaves the room [14:08:55] From the exaggerated body flexure displayed by that Synapho, perhaps there is substantial bottom current here? [14:14:20] Parantipathes [14:14:39] The squat lobster are characterictic associates of this genus [14:15:40] lesliesautter leaves the room [14:16:27] Mucus net... not sure what created it. [14:16:30] dhugallindsay leaves the room [14:16:37] Little plate sponges next to amphipoid [14:17:13] Brittle star arms in hole [14:17:47] Cheryl or Leslie: f no one else is making a notation of the collection in SeaScribe, please type the specimen numbers here and I will add them. I created a placeholder. [14:18:26] Will do. Consulting the sampling lead to make sure we are correct. [14:19:34] LarvaceN [14:19:47] LARVACEAN [14:20:08] Sorry about all caps! Can't keep track of my fingers this morning! [14:20:27] It too early to be yelling scott ;) [14:20:52] taraluke leaves the room [14:21:05] haha [14:21:52] Hi Scott, this is Stephanie [14:22:09] If this thicker-looking orange Stichopathes is the same as the one we have collected further north, then out genetic data suggest it is not a Stichopathes at all, at least they are not on the same genetic lineage/clade. [14:22:20] The Stauropathes is D2_DIVE04_SPEC01BIO [14:22:37] The SECOND Bathypathes is D2_DIVE04_SPEC02BIO [14:22:51] Thanks Cheryl [14:24:47] We also took 3 niskin samples at that site, SPEC03, 04, and 05. the sample logger isn't letting us enter them thus far [14:31:32] lesliesautter leaves the room [14:31:53] I'm not sure if you've already been looking at sponges today, but we just passed a couple of white glass sponges I hadn't seen before. Please get a close-up if you see them again. [14:33:22] michaelvecchione leaves the room [14:34:53] will do. sorry you have the lag in time. [14:35:53] I didn't hear Cheryl - is that Lophelia? [14:37:38] Sponges? [14:37:54] Oh! [14:38:07] Sorry. This is not the sponge I was referring to [14:38:16] The sponges I saw were bright white and taller. [14:38:31] Looks like a bamboo coral [14:38:47] from a distance, anyway [14:38:56] adriennecopeland leaves the room: Replaced by new connection [14:39:35] Yup - dead bamboo coral with plenty of overgrowth [14:39:45] Neolithoides? [14:41:09] Bad spelling: Neolithodes [14:41:21] coral may have been a Keratoisis [14:43:09] Looks like a dead Metallogorgia as well... [14:43:21] Also with an anemone [14:43:47] is there a brittle star at the top? [14:44:13] Looks like the brittle star is also gone... so a long dead one? [14:44:22] Good signs of things to come [14:44:47] would be nice to get a record of Metallogorgia from here [14:45:02] sorry, missed begining of the dive [14:45:10] Branched sponge? [14:45:23] black is Parantipathes [14:45:29] Nope - I was fooled [14:45:39] primnoid [14:45:43] Thouareella primnoid [14:45:57] Thouarella [14:46:02] Hi Tina! [14:46:13] one "e" [14:46:23] agree with Scott, black coral is right [14:46:32] Thouarella agree [14:46:45] and cup coral at base [14:46:53] my messages must be going the long way round as there is about a 10 second delay before they show up [14:46:53] lesliesautter leaves the room [14:47:04] Collection of Thourella? [14:47:13] Maybe a Heteropathes behind it [14:47:18] can we look at blak coral, bushy one right [14:47:24] What is at base of THouarella? [14:47:28] same with images.... I see your comments and then I see what you are talking about [14:47:35] I cannot see it properly [14:47:53] yes, looks like Heteropathes, perhaps americana [14:48:02] Not sure what was at the base? [14:48:11] I think there was a gastropod under the THouarella [14:48:28] Cairns described T. grasshoffi from W Atlantic but colony was not this large or robust [14:48:42] and right and left are apparently both Stauropathes and I have heard it was collected [14:48:54] Collection of part of Thopurella? [14:48:58] Tina: this looks like a place you could retire. [14:49:07] We collected it in Oceanographer canyon [14:49:21] Parantipathes, perhaps hirondelle. but not 100% sure [14:49:32] @Tina: we collected a Stauropathes and a Bathypathes earlier today. [14:49:38] I think it would be good to grab a piece. [14:49:44] of the Thouarella [14:49:47] I have another species under description [14:50:00] @scott, yes, asako whatupped me) [14:50:14] Sure, snip a piece of THopouarella [14:50:23] from where @Tina [14:50:35] may be interesting to get Heteropathes [14:50:47] if it is common [14:51:05] That is the first heteropathes Tina [14:51:15] @Les, Meteor seamount and Hiere [14:51:23] I did respond Cheryl: I said collect a piece of Thouarella [14:51:35] It would be not bet to get Heteropathes [14:51:47] not bad [14:51:50] I vote Thouarella! [14:52:02] Would be good in fact [14:52:14] I vote both [14:52:22] Great- thanks. Setting up for collection [14:52:32] I am OK for Thouarella, we already collected two black corals this dive [14:52:33] dhugallindsay leaves the room [14:52:40] Verification- heteropathes is the tall one on right? [14:52:53] looks like three Heteropathes colonies here [14:53:00] @Les, great! if it is possible, I also vote both :) [14:53:13] Heteropathes is TINY at the back of Thouarrella [14:53:40] Oh good- thanks Tina. So many species here! [14:53:54] @Les, I can see three Stauropathes... but only one Heteropathes [14:57:28] nope, we had one dead bamboo [14:58:42] I am leaving you all for a while. See you later. Looks like it could be a good dive for sessile communities. [14:58:50] @Tina, my bad black coral taxonomy [14:59:40] scottfrance leaves the room [15:00:10] Bathypathes and Corallium [15:00:44] Corallidae at least with a worm run along the stalk [15:01:28] and there is one more species of black corals just left to Stauropathes [15:01:38] has to be Aphanipathidae [15:01:55] could the light pink one be an anthothela? [15:02:43] Les, no... I do not think so, just bad projection [15:03:12] also we have Stichopathes [15:03:46] apparently two species of stichopathes [15:05:16] this coral cluster is very similar to what we saw on the western end of the New England seamount chain. [15:05:31] it is coral dive! [15:05:44] has lophelia, desmophyllum and some gorgos [15:06:14] has been here a long time also judging by the manganese coat on the dead corals [15:06:48] and a little Hertwigia? [15:07:25] @les, this thing, that looks partly like coral, partly like nudibranch... is it possible to be bivalve? [15:08:04] not sure I know what you were looking at @Tina [15:08:31] lesliesautter leaves the room [15:10:49] went back and looked.... and I have no idea what it was! [15:11:54] very unusual behavior... too bad Mike isn't logged in [15:13:29] Enallopsammia? very nice [15:13:35] Ideas on coral [15:14:02] zooanthid [15:14:08] Some parazoanthids are yellow. [15:14:16] the yellow one... also a member of the group as I noted before [15:14:33] some zoanthids are yellow but this has a continuous yellow framework [15:14:41] I think it Enallopsammia [15:14:50] Hi all, It seems Enallopsammia [15:14:53] Oh cool [15:15:17] That's what I thought too. rostrata [15:15:30] agree @Cheryl [15:15:50] Gonostomatid? Cyclothone? [15:16:09] Bathypathes, Stichopathes, several Stauropathes [15:16:22] Yeah Bobtail [15:17:50] siphonophore [15:18:03] but very small [15:18:03] adriennecopeland leaves the room [15:18:41] Tina - this is a great dive for you! [15:19:46] robertcarney leaves the room [15:20:01] @kasey, yes) it is lovely dive [15:20:20] Anthomastus [15:20:32] can we zoom anthomastus? [15:21:54] shrimp with huge pleopods [15:21:57] irissampaio leaves the room [15:23:03] Pseudoanthomastus [15:23:12] shrimp is Plesiopenaeus or maybe now it is Aristeopenaeus, I can never remember [15:23:23] this is Tina's dive indeed! :) [15:25:21] what's that white branching thing next to the purple sponge [15:25:35] this may be Bryozoan above the blue sponge [15:25:51] irissampaio leaves the room [15:27:13] louispenrod leaves the room [15:27:55] Chaunax methinks [15:28:20] I like orange eyes [15:28:49] I always thought these guys looked like they were made of plastic [15:29:01] We called them Benny fish after Benny Rohr on Oregon 2. He was a little fat. LOL [15:29:14] haha [15:29:21] it looks like a tiny dog at dogshow [15:29:51] lesliesautter leaves the room [15:29:52] they can swim, albeit somewhat awkwardly and not too fast [15:31:41] Chaunax coloratus. There are several species in this genus. When this species is disturbed and bugs out, the backward facing circular opercular openings show black and appear like eyespots - suggesting the head of a very large fish. The short lure within a cavity on the head in this species may not be a visual lure but a chemical lure. The visual lures are more typically elongate and dangled or twitched in front of the mouth. The chemical version is held motionless within the head pit [15:31:46] last was good) [15:32:21] sophie and trey here woop woop [15:33:30] thanks @Ken! [15:35:46] Regarding the yellows and blues that might seem functionless at 1000 m +, they may actually be functional. At mid-latitudes, given the density of photons hitting the surface of the ocean, and the extinction coefficient of solar illumination with deph in clear ocean water, enough photons survive to at least 1200 m to be sensed by the hypersensitive retinae of many deep-sea fishes. Only a few photons per sec are needed to be sensed. Additionally, from the work of Edith Widder, many organisms at depth are fluorescent - so visible color may be related to that capability [15:38:06] why we have such terrasses? they are real sealevel? [15:39:04] Chaunax species are very good at changing color. In the Gulf, C. sutkussi, can be either solid red, red with whitish spots, red or pink with lots of yellow spots, or gray with a reticulated color pattern. The red C. coloratus seen on this dive is sometimes translucent whitish with a blue abdomen. [15:39:49] Parantipathes [15:41:57] looks like piece of coral, covered by crust [15:42:06] this substrate is a lot like the sunken carbonate blocks we saw at Bahamas, similar depth [15:42:06] irissampaio leaves the room [15:42:33] Black coral is sitting at rock sample that makes it even more perfect [15:42:46] Gastropod to left of rock [15:43:26] I think this is part of a large ancient platform, perhaps Miocene or so in age, not sure though [15:45:20] corals! [15:47:18] can we zoom at whitish coral [15:47:48] Looks lie an Enallopsammia [15:48:08] *like! [15:49:07] another Heteroapathes [15:49:24] can we zoom left [15:49:36] out of screen now [15:49:42] Sending an email to Cheryl with attached image showing Chaunax false eyes when swimming away - from OE 1708 in Pacific, a Chaunax very close to C. coloratus [15:51:28] Thank you Ken! [15:51:39] can we zoom at pink Parantipathes [15:52:53] Some Anthothela-;like coral [15:53:33] Anthothela, not Paramuricea: [15:53:43] agree for Paramuricid [15:53:57] There was also purple Clavularia overgrowing the skeleton [15:54:03] Anthothela was purplish one [15:54:26] Agree Paramuricea - surprised not to see an asteroschematid on it [15:54:38] Don't sample this one [15:54:42] irissampaio leaves the room [15:54:56] For connectivity we are looking for Paramuricea with Asteroschema [15:55:05] and this doesn't have Asteroschema [15:55:45] can we zoom at Parantipathes-like branching [15:55:53] right [15:56:13] Note: you could opt to sample it for other reasons if desired, but not for the connectivity sampling is my point. [15:56:42] Scott, we really need that parantipathes to look [15:56:59] Okay Scott. May have been a good sample for others, but no one shouting about it. [15:57:12] Do you see more paraanthipathes Tina? [15:57:19] Not enough people today to shout! [15:57:23] More on Chaunax. It is good to be red at depth, red absorbs the sparse blue wavelength photos surviving from the surface and also the primarily blue wavelength of bioluminescence of biological light at depth. But also good to have startle eyespots, even when you look black - because some predators with yellow eye lenses (like Bathysaurus) can defeat red camo (and ventral photophore ambient light matching) to reveal prey trying to hide in the near solar blackness of inner space [15:57:31] Can crustacean people identify these squats? Munida, Munidopsis? [15:57:38] it was only one, we passed it three times already [15:57:49] it was branched [15:57:53] Father's day wrapping paper... [15:58:01] I've seen most Munida [15:58:17] @Cheryl thanks [15:59:38] that fish looked like it was having trouble waking up! [15:59:51] Is that the same as Royal Red shrimp? I eat them. [15:59:59] Stauropathes [16:00:10] Stichopathes [16:00:23] Enallopsamia [16:00:32] I don't think so @Tom.... but royal reds are penaeids, I think [16:00:47] @Les Thanks [16:01:22] Synaphobranchus affinis. S kaupii is very similar and co-occurs in same rea and depth, but is thicker bodied. Les - when hit by the ROV lights, synaphos often gape, run into objects, etc. Probably a reaction to having very dark-adapted retina suddenly blasted with intense ROV light [16:02:14] @Ken, yeah not surprised, although we don't often see that reaction. The lights must be hard on their eyes [16:02:27] Yup - Chrsogorgia [16:02:49] zoanthid [16:03:02] The gape is usually followed by a head shake - and you saw that just now [16:03:08] ex-bamboo [16:03:16] Good call Cheryl - zoanthids [16:03:35] all over the ?keratoisis [16:03:53] I'm guessing on the branching pattern [16:04:29] where are the rest of the bamboos? [16:05:19] the hard corals are much like those of the western end of the New England seamounts, but the gorgos not so much [16:05:38] Leiopathes [16:06:10] Bathypathes [16:06:57] Stauropathes [16:07:16] can we zoom at pink& [16:07:25] I missed the Leiopathes [16:07:39] my guees is that left is a different genus [16:07:49] Oh - I see in the back [16:08:49] I missed perhaps Trissopathes twice that is not reported from here [16:09:41] primnoid [16:09:46] Primnoidae Candidella [16:09:51] perhaps candidella [16:10:02] This is the species that has polychate worm tunnels on it [16:10:10] yeah, Candidella [16:10:25] and there are worm tunnels [16:10:43] at least one on the left [16:10:55] @les, agree for wormruns [16:11:01] Enallopsamia in the bkgd [16:11:14] Candidella maybe imbricata [16:11:24] Telestidae [16:11:36] is this yellow sponge is well known? [16:11:49] @Les: we could be on the NES! This looks so similar [16:11:57] yeah, we see it everywhere on the seamounts in NW Atlantic [16:12:11] Agree @Scott, I made that comment while you were away [16:12:21] big one looks like not Leiopathes for me [16:12:31] We saw this yellow sponge a lot on the New England Seamounts, but I'm not sure it has ever been collected. Does anyone know? [16:12:41] sorry - Solenosmilia? [16:12:50] the yellow sponge we have been calling Hertwigia [16:12:55] another primnoid [16:13:00] We did some slurps of it for Shank [16:13:13] thank you Les and Scott! [16:13:22] It is very difficult to get without falling apart [16:13:35] beautiful Candidella specimen [16:13:47] same brittle star too @Scott [16:14:41] It would be nice to have a piece of the yellow sponge so that sclerites can be checked [16:14:54] I want zoon at darck black coral [16:14:58] sorry, spicules! [16:15:10] zoom [16:15:17] Love the way it is growing intertwined with the coral [16:15:17] irissampaio leaves the room [16:15:43] maybe the coral doesn't like that so much [16:16:12] please [16:16:28] no way [16:17:16] @Scott, what is missing from this "grouping" is the little bramble bamboo [16:17:23] Has anyone seen mysids or amphipods? Just that shrimp coral associate here. [16:17:35] @Les: for sure. [16:18:30] Very interesting how concentrated that cluster was at the edge of the rock feature. Very telling. [16:19:27] Ok, @scott, just for you this big colony is apparently NOT Leiopathes - but we did not zoom and dark-red colony left of all Stauropathes I have no idea what [16:19:40] bamboo coral behind this stichopathes [16:21:52] erikcordes leaves the room [16:22:42] For the coral taxonomists, what do these look like when you get them to surface. Can you still see extruded polyps. They look so delicate. What are the types stored in? [16:23:16] @Tom: it varies by coral type... [16:23:17] lesliesautter leaves the room [16:23:38] Some of the corals don't have enough coenenchyme tissue for the polyps to retract into... [16:23:53] ...for example, the chrsyogorgiids and most isidids... [16:24:06] @ thanks Scott. [16:24:18] ...but others, like the Plexaurids, can fullt retract [16:24:24] And then there are some in between! [16:24:38] And some that can retract, only some polyps are retracted and other are partially out. [16:27:25] hydroids [16:28:26] scaleworm if polynoid had long parapodial seta. [16:28:55] I think these frilly edged glass sponges may be in the family Farreidae [16:29:32] Black coral branched Parantipathes? [16:29:45] Or a Taxipathes? Tina? [16:29:58] Parantipathes or Sibopathes [16:30:12] Oh yeah - Sibopathes, not Taxipathes. Thanks. [16:30:16] Taxipathes is also possible [16:30:31] @Tina: lol! [16:30:46] I have seen only couple of subspecimens and never full colony [16:30:53] irissampaio leaves the room: Replaced by new connection [16:31:02] asakomatsumoto leaves the room: Replaced by new connection [16:31:17] large fan [16:31:31] my guess is that it may be Sibopathes macrospina that is not Sibopatehs [16:31:54] Mysid symbiont [16:32:10] Or just hanging out there. [16:34:06] The mysid is swimming to right. [16:35:02] irissampaio leaves the room [16:35:02] well, we've seen that before! too beautiful! [16:38:35] Awesome. [16:39:25] So, as a point of reference, to our south on the Bahamas Escarpment, we collected samples from these candelabra isidids at 1255 to 1468 m, so right in the depth range we are today. [16:41:01] Farreidae glass sponge [16:41:39] Stichopathes [16:42:28] Yellow sponge was growing as bracket fungi. [16:45:18] Parantipathes [16:45:44] Stichopathes below [16:47:18] What a great wall of coral. [16:47:47] Awesome spot. [16:47:58] I did not see any associates on that Parantipathes [16:48:07] Maybe the current hits these cliffs and the current directs upward into the bracket sponge. [16:48:12] Great edge to the ledge [16:48:30] we saw this fish on Rehoboth with the Acanthogorgia armata.... Ken will have to supply the name [16:48:45] Is it a codling...? [16:48:47] mattdornback leaves the room [16:48:59] Anthomastus [16:50:01] can we zoom at dark red coral below bamboo to left [16:50:10] Nice Stichopathes above the Parantipathes - think Tina saw this one [16:50:19] will request [16:51:33] just off screen [16:52:27] Not seeing much dead portions of coral colonies or coral branches. Has it been this way the entire dive? [16:52:48] @Scott, I think we might need to think of this as a western boundary undercurrent community. Stretches maybe from Newfoundland to Bahamas [16:53:01] This is the first distinct "cliff" of the day @Tim [16:53:11] Fully dead coloniy here [16:53:27] These are more live than what we saw at lower parts of the scarp [16:53:39] @Les: but I think it skips some of the midAtlantic canyons... Will be very interesting to see communities in the dives in the coming 2 weeks. [16:53:49] Okay. Thank you. Noting not seeing much in the way of coral assocaites. [16:53:53] B clade bamboo in the back [16:54:08] Bathypathes or Telopathes, [16:54:18] Umbellapathes? [16:54:29] B clade is the squiggly whip [16:54:47] and white has to be Alternatipathes [16:55:13] @Tina - sorry, we had to keep moving. [16:55:27] timothyshank leaves the room [16:55:50] @Scott, is that due to lack of appropriate substrate? [16:56:50] @Les: good question! I was wondering if it had something to do with current flow. At one point didn't we think there was an offshore southtward flow that then curled north when it hit the Bahamas Escarpment... [16:57:25] left perhaps leiopathes [16:57:55] But there seemed to be evidence in the northern canyons of the current going in and out of the canyon, at least in the lower part. Interesting. [16:58:09] Another big bamboo coral [16:58:21] the biggest yet? [16:58:34] Strange sea anemone that we passed [16:58:46] I don't think this is Keratoisis [16:58:58] A zoom would be helpful [16:59:11] basket star on bamboo- yes can we zoom? 1247m [16:59:37] It was apparently radicipes [16:59:49] polyp density on that bamboo was too much for Keratoisis. [17:00:03] So maybe something we saw further north, but maybe not [17:00:37] ophiuroid on bamboo [17:00:59] without zoom can't tell who is who [17:01:14] Yes, the bamboo on the left has the oph [17:01:55] I would guess J clade or one of the minor clades for this one [17:02:34] Missed what you said @Scott [17:02:49] I agree: J clade [17:02:58] This one has interesting colored polyps [17:03:08] I was pointing out the abherrent branching in there... [17:03:19] saw few barnacles near the top of one of the branches - glyptolasma like [17:03:30] Eevidence that there was damage and then odd regrowth following it. [17:03:35] good point [17:03:39] That pattern is becoming more and more common [17:03:48] Agree @ Scott. Great Cheryl for commenting on the Uroptychus on Paratipathes- one of my favorites. [17:04:10] looks like ophiocanthid oph [17:04:24] maybe some regrowth on the arm(s) [17:04:42] suggest regrowth..... [17:04:50] tentacles have been pulled into top of polyp [17:05:12] but looks like all of the arms have that color and size difference have been impacted [17:05:27] lots of regeneration in the b star [17:05:39] all but one arm- I think regrowth. [17:05:46] Great imagery - retracted tentacles nicely shows the intertentacular sclerites [17:05:57] could it be that this is why we are not seeing abudant ophiuoids on these corals? - predation pressure high? [17:06:11] Nice job- thank you. [17:06:23] on coral looks like polyp contracts a little but arms pull into top and are guarded by long needle sclerites [17:06:36] @Les: yup [17:07:00] small fish [17:07:12] If they are polychaetes, we never see the gill plumes. Sabellid? I don't know. [17:07:26] a living Metallogorgia! [17:07:38] Metallogorgia - Ophiocreas brittle star [17:07:52] old dudes [17:07:52] upasanaganguly leaves the room [17:08:05] we'll try to get a look at the fish [17:08:22] yes, no little poodle clusters of branches down the main stalk [17:08:39] good video of Ophiocrease associate [17:09:43] Two Leiopathes [17:10:03] was that a branched bathypathes? [17:10:40] timothyshank leaves the room [17:11:07] Where are polyp mouths on the liopathes. How does this poly form work? [17:11:10] asakomatsumoto leaves the room [17:11:19] polyp [17:12:17] @Tom: The polyps are relatively small, so it is hard to discern the mouths without a real good close-up... [17:12:27] Nice pair of Leiopathes- no apparent associates. [17:12:40] ...but the polyps are not stretched out like they are in the Schizopathidae... [17:12:55] @Scott Thank [17:13:05] ...in general, there is a short raised hypostome among the tentacles and the mouth is at the tip of that. [17:13:40] Possibly hippasterid asteroid there... coral-eating seastar [17:16:13] Awesome majesty of the bamboo coral! [17:17:59] That majestic bamboo we passed looks like a Bahamas one we collected that would make it a Keratoisis D2 clade [17:19:17] Great observation. Abrasion of the coral enabliing this posiiton on the ophiuroid a good hypothesis. [17:21:31] Anthamastus behind this sponge [17:22:24] skate case? down in the center of that sponge? Squinting now.... [17:22:52] lesliesautter leaves the room [17:23:12] TIM - YES skate egg case down in the hole [17:23:22] i am not sure if you got an ID on the pink fish eariler-but it is a Gaidropsaurus…and I think it would be a range extension. Seems pretty far south for the genus, but i have to check the literature [17:23:47] Off to get some lunch... [17:24:33] Andrea - I was away from the computer for about 45 min - missed the gadid - will scan back and try to find. This steep broken rock/mudstone would be ideal Gaidropsaurus habitat [17:25:09] @ken i just saw it on Facebook. not sure what species it is yet, but does seem like a southern range extension [17:26:24] @ken it was seen ~~40 min ago [17:28:43] lesliesautter leaves the room [17:30:39] rockpen [17:30:51] ? [17:31:43] is that the world's smallest brittle star in there? [17:31:59] Yes! [17:32:09] maybe cutest... [17:32:31] Passionflowers have the ant symbionts but the plant provides a nectary for the ants. Ophiuroid must get something. Nothing is free. [17:32:38] Anthoptilum? [17:32:51] Andrea - your ID is correct, Gaidropsaurus, probably G. ensis - but the pelvic filaments look unusually elongate, Also, back 80 min I found a very beaten up ophidioid, probably Diplacanthapoma - but tough to tell from all the marks/scars on the body [17:34:12] @ken yes, likely G. ensis. and yes, agree that was a diplacanthopoma cusk eel [17:34:27] might be a slime star? [17:34:35] @Tom: agree. I think the brittle star gets to feed on whatever lands on the Metallogorgia [17:34:50] Hymenaster [17:35:04] Agree with @Megan [17:35:44] thanks for the fish IDs @Andrea and @Ken. both are common on the New England seamounts, but I couldn't remember the names [17:36:42] If I recall correctly from East Coast trawlng and subsea missions, the appropriately named 'Threadfin Codling' was captured and observed perhaps as far south as Cape Hatteras or Cape Lookout. Once you get further south and onto the 'Tail of the Bank' of Blake Plateau, codling habitat becomes pretty scarce. I do not remember the depth range. [17:38:27] @ken. this is the right depth range, but a bit south of hatteras. [17:38:54] Other sponge had hermit crab associate? [17:39:43] have we seen a wreckfish yet? [17:39:57] @ken, but the temp is 4deg so makes sense [17:40:09] yes, hermit crab on sponge. [17:40:18] pretty deep for wreck fish no? [17:40:27] OK - I just consulted Fishbase. Gives Hatteras as the southern limit, and 2000 m. And I spelled the species name wrong. No 'u' in 'sarus'. But on distribution, Fishbase is not updated as often as would be definitive [17:40:53] Kasey - [17:41:40] @Andrea, I think this fauna is associated with the LSW deep western boundary undercurrent. Not sure how much farther it goes, but the current itself is still identifiable off Brazil. [17:41:55] *it, meaning the fauna [17:42:06] Kasey - this is a bit too deep for a wreckfish, but getting close [17:42:28] from the T and S data we are definitely in the LSW water mass [17:42:41] @les yes makes sense [17:43:12] Thanks Ken-maybe in the next couble days! [17:47:10] moridae [17:47:45] not sure what it is…looks like a laemonema…but not sure. ken?? [17:47:58] this is a cusk eel [17:48:05] Desmophyllum - this looks similar to a wall we saw in Norfolk Canyon at about this depth. [17:48:19] small fish was a moridae [17:48:38] could you zoom on the head of the cusk eel [17:49:03] W Boundary Undercurrent flies along the upper slope and collides with the deep part of the Gulf Stream off 'The Point' NC, leaving a very curious area of absolutely no current between 200-900 m depth behind the colliding currents (shoreward). In that 'no horizontal and no vertical current zone, there is very low oxygen, lots of suspended marine snow, and scant midwater or bottom life, and what fishes are there are diminutive. Some of that is reported in: 1996. Sulak, K. J. and S. W. Ross. Lilliputian bottom fish fauna of the Hatteras middle continental slope. Journal of Fish Biology 49 (Supplement A): 91-113. [17:49:13] Sorry Andrea- we've moved on [17:49:31] np…if you see another one. thx [17:49:46] You got it! [17:50:54] Have to check out. Thank you. Hate to miss things. [17:51:41] tomhansknecht leaves the room [17:52:16] Thanks for joining Tom! It's been quite a dive! [17:55:08] Andrea - I stepped away for a few minutes. I am mystified by the large gadiform fish with a barbel and an absolutely circular black spot on the head. Never have seen anything like that. Looks like someone applied an old Peterson plastic disc tag to the side of the fish's head [17:55:29] @ken i missed that fish. what time was that? [17:58:08] My affiliation is no longer SMCC. I'm now with the North Carolina Museum of Natural Sciences. I thought that was updated.. [17:58:37] zachproux leaves the room [17:58:41] sorry Megan! That's my fault - I worte it off the top of my head without checkign the sheet [17:58:52] sorry about that! [17:59:02] About 10 min ago. But I was blitzing through. Need to go back - I suppose the black spot was the eye - but weird, very large and black. Maybe a socket from which the eye is missing. [17:59:45] No worries and thanks! I'm the collections manager for non-molluscan inverts so myself and my supervisor (Bronwyn Williams) along with the NCSM in general are very excited to take part [18:01:32] kensulak leaves the room [18:01:38] @ken it was actually a small moridae. but not sure what genus it is…the spot was a very large eye [18:03:45] no idea on this bamboo... internodes are moderately short, polyp sclerites not too visible [18:05:05] pteropods are gastropods [18:05:14] Anthomastus [18:06:18] like order of subclass heterobrancha [18:06:29] @ken, thanks for your info on the slow zone south of Hatteras. The deep drifter data shows the some part of the DWBC gets entrained into the momentum from the Gulf Stream, so many larvae will get carried out to the ocean interior [18:07:26] they are coming together with land snails and nudibranchs [18:07:52] But the outer portion of the current does continue south, or maybe the outer and deeper part.... so you lilliputian story is very interesting [18:08:05] close to nudibranchs anyway [18:08:27] Alternati-pathes [18:09:33] more Bathypathes [18:10:09] for how long we are staying at the bottom? [18:11:10] About 1.5 hours longer [18:11:17] tube anemone under ledge [18:12:47] zoanthids [18:13:23] any more collections? [18:13:43] I think we have space for 1 more collection... [18:14:20] Would be nice to get an ID on these zoanthids. [18:14:35] My vote would be for that strange J clade bamboo unless something else truly different shows up [18:14:50] Yes, room for one more collection- what are priorities? [18:15:27] I was away from the computer Les, so not sure which one you are referring to [18:16:06] Please give a shout out when you see a J clade bamboo [18:17:03] like this one which I think is the same as the one we were talking about earlier that had the unusual regrowths [18:18:15] or do you think we already have that @Scott from the Bahamas? [18:19:51] @Les: hard to say. It looks a bit like CAT2081, which came from 1227 m depth, so consistent with depth [18:20:20] we have not seen a sponge overgrown with zoanthids like this... [18:20:43] I think the sponge is a Farrea but no idea on the zoanthid [18:20:56] lesliesautter leaves the room [18:21:55] cerianthid? [18:22:08] yep [18:22:52] Have a look here for an example of the association I'm referring to in the Pacific: https://www.ncddc.noaa.gov/okeanos-animal-guide/SceptrulophoraOther031.html [18:22:56] We have seen Aphrocallistes this densely packed with yellow zoanthids on the Florida reefs. [18:23:07] Clavularia-like [18:23:22] Thanks @Sandra, interesting [18:23:43] Clavularia? [18:23:58] that would be my guess [18:24:12] and Candidella at the back [18:25:17] is this possible to collect? [18:25:38] should be, it is on a dead sponge skeleton [18:25:49] can we zoom Anthomastus? [18:26:57] it is very difficult to collect when Clavularia attached on the rock... [18:27:03] Chrysogorgia [18:28:11] this looks like a uroptychus chirostylid [18:28:33] Maybe Anthothela (white colony) [18:28:43] this one is real Anthomastus [18:32:53] Sibopathes-like [18:37:50] Possible Cladarisis [18:40:20] These look like serpulid polychaetes - have the calcareous tube [18:41:03] Cladarisis...nice [18:41:19] very distinct branching pattern [18:41:36] that was the Y sahped bamboo at the bottom [18:42:21] haha I see @Scott you had already spotted it... that's what I get for popping in and out! [18:42:23] lesliesautter leaves the room [18:42:54] anyway, that definitely extends its range... although we did see it in Gulf of Mex [18:45:40] Can we look at spindly coral on top of ledge [18:46:00] That looks almost exactly like Cladarisis nouvaniae! [18:49:02] my thoughts exactly @Scott [18:50:03] this one could be the same but standing upright [18:50:23] or a relative in S clade [18:50:45] Definitely in the S1 clade if it is not C. nouvaniae [18:51:12] *nouvianae [18:51:33] Oops! [18:51:48] :-) [18:52:22] haha, its French.... [18:52:38] I agree- comparing the current dives to the upcoming canyon dives to the north will be very interesting. [18:52:50] leiopathes [18:53:20] bamboo [18:53:34] leiopathes = old! maybe even very old [18:54:13] another S clade? [18:54:25] This one could be a "Lepidisis" in the true sense, i.e. L. caryophyllia [18:54:36] good point [18:54:50] @les, for some reason they do not like to zoom at Leiopathes and weird Parantipathes that perhaps something else [18:55:02] Except I see it is yellowish at the base, which I recall only on S1 clade bamboos [18:55:18] also good point.... [18:55:31] but this on is OK Leiopathes [18:55:42] I'm full of conjectures, just not absolutes! [18:55:52] maybe a collection of weird parantipathes would be good [18:56:27] pf. they do not like to look closer, how you would like to collect [18:56:39] somebody should, or maybe is, telling story of ancient Leiopathes.... oldest living animal [18:57:06] What is approx time off bottom? [18:57:32] @Tina: you think this Leiopathes is a good collection target? [18:57:46] how old are some of these black corals? [18:58:08] leiopathes off Hawaii aged at 4900 years [18:58:31] probably most of them are in the 2k year category [18:58:45] agreed Les - please share - it's a great story [18:58:50] especially as we are seeing so many of them [18:58:57] @scott, it is OK.. to collect, because there is request for [18:59:07] I would think it will be good to measure the base [18:59:21] yes base needs to be measured. [18:59:35] how old would you think this one is based on those ages? [18:59:57] @Kasey, Brendan Roark age dated the specimen collected at 450 m or so off Oahu [19:00:12] I have his paper here somewhere [19:00:21] It is too hard toi give an absolute age because it depends on food availability, depth, temperature, metabolism, growth rate and species! :-) [19:00:26] @kasey, I do not know, Hawaian species seems to be the oldest. couple of thousands easily [19:00:39] should all of today's corals be straight EtOH or should some be formalin first? [19:00:53] Scott, I would put Leiopathes cf, expansa [19:01:02] thanks! [19:01:17] The only know older living thing are the bristle cone pines that have been dated at 5600 years, or something like that. [19:01:38] I would say ethanol, unless Tina has a compelling reason for formalin for the black corals. [19:02:08] still zoom of base would be good [19:02:19] @kasey, they whant in alcohol. but my request to put small fragments of black corals in formol - it is very rare when we have polyps in good shape for morphology [19:02:41] that's great [19:03:26] ok - we can do that! For all of them? [19:03:36] @scott, it is attachement, we need to masure the stalk [19:03:47] @kasey, it would be brilliant! [19:03:56] measure [19:04:19] attachment is growing in its own way [19:04:41] cherylmorrison leaves the room [19:04:43] a candelabra bamboo [19:04:57] hope it is not eating bamboos [19:05:10] and is there any concern about quick deterioration? As in do we need to bring down ethanol in a container for immediate preservation? [19:05:22] with basket star [19:05:33] no, it is suspension feeder [19:06:00] but with all those tube feet, polyps could get trampled [19:06:39] andreaquattrini leaves the room [19:06:42] @kasey, they may degrade pretty fast, may be it is a good to preserve them immediately [19:07:13] ok - we will try! [19:07:24] @les, but there is no tissue below the basketstar [19:08:34] There is no record I know of that basket stars eat corals. [19:08:41] we will bring down to the vehicle: 1 sub sample container of ethanol and 1 subsample container of formalin for each of the samples. We will take quick clips and then the rest will be processed regularly. Sound good? [19:10:38] louispenrod leaves the room [19:10:59] @Tina, yeah I saw that. I thought maybe the polyps were just getting smothered or beat up [19:11:09] @kasey, sounds excellent! [19:11:26] So this is where all the candelabra bamboos have been hanging out [19:11:42] @les, actually feather stars are also sitting at naked area [19:12:10] if they are eating the polyps that would be very interesting [19:12:21] @les, no, I guess one was up [19:13:03] I want coral left!!! [19:13:17] dark red one [19:13:37] always too late) [19:14:16] What taxon Tina? [19:14:43] nothis! [19:14:53] centerd [19:15:06] that one [19:15:33] We are out of bioboxes for collection [19:15:41] Oh sure. It gets all spongy and here come Chris K... ;-) [19:15:44] this may be Trissopathes.... [19:16:03] A little late to the party guys. Sorry [19:16:13] Can you collect? [19:16:21] Hi Chris! [19:16:29] Is this a Farreidae? [19:16:39] Boxes full [19:16:47] @chris, you are just for the sponge [19:16:59] I think we are full on collections [19:17:10] This is a really weird sponge that could be related to Tretopleura [19:17:17] Chris - your lucky day! [19:17:29] there is always a space for Cris's sponge) [19:17:39] Glad to see you write that Chjris! [19:17:52] I had sent you an email earlier asking about Tretopleura and anemone/zoanthid symbiont. [19:18:04] I couldn't recall if it was an anemone or zoanthid [19:18:10] I was guessing those were zoanthids on the sponge. Don't think they are anemones. It would be great to see what they are. [19:18:14] I've never seen a growth form quite like this - has it been seen elsewhere? [19:18:33] it is... pretty small sponge, by the way [19:18:49] it is relatively common on New England seamount [19:19:04] Well, we have it now! [19:19:34] @les - thanks, interesting, we didn't see it in the MA canyons. [19:20:03] off bottom time is close to 1530 EDT [19:20:30] great catch, by the way [19:20:43] agree Scott. I don't think we sampled such a sponge on the NE Seamounts [19:21:23] EX1806_DIVE04 ROV Ascending [19:21:38] we didn't sample many sponges on NES [19:21:42] we have best ever pilots! [19:21:45] Lovely dive -thanks Ex team! [19:21:56] nice dive, as always [19:22:00] spectacular and memorable dive. Thank you! [19:22:10] it was great dive! thank you very much! [19:22:10] leswatling leaves the room [19:22:23] Hi Chris!!! [19:22:23] sandrabrooke leaves the room [19:22:33] @Les: I don't recall sampling any sponges on NES. Unless it was on a coral!

[19:45:13] Hi Mike! [19:45:27] Howdy. Not on the line yet. [19:48:58] can you clarify, are we on the transect? [19:50:44] 1941 UTC transect start [19:51:10] 950 transect done [19:52:31] lesliesautter leaves the room [19:52:52] solmissus verify species - tentacle ends [19:55:07] 915 m dense layer of marine snow [19:56:37] kaseycantwell leaves the room [19:56:45] that's a good question - zooplankton dense or is this marine snow? hard to tell from video [19:58:45] I guess we will see better when we set for the transect. [19:59:00] luckily marrine snow doesn;t hop like a copepod [20:00:02] didn't see it. [20:00:17] that wouild be very cool [20:00:58] Cyclothone [20:01:07] Sternoptyx hatchetfish [20:01:19] love these guys [20:01:48] snot [20:02:23] start 880 transect 20:01 UTC [20:03:28] marine snow! [20:03:51] physonect [20:04:01] nectophore morphology is important [20:04:16] zoom on nectophore [20:04:22] swimming bell parts [20:04:34] nice! [20:04:46] very very nice [20:04:56] well done! [20:05:03] Mike -you should call in! [20:05:47] so nice! [20:06:13] great video! [20:06:23] tentacles are very unique [20:07:35] cydippid ctenophore [20:07:44] colloblasts [20:09:34] we have quite a few ctneophores from Okeanos video that we are studying. We are seeing many species and some potentially new ones. So it is an excitting time for ctenos [20:09:59] great behavior [20:10:13] strange [20:10:18] expect swimming [20:10:58] with the tentacle structure of Atolla you expect swimming to be the behavior during feeding. [20:11:08] maybe not doing well? [20:11:20] ew [20:11:41] bonus time!!!!! [20:12:27] sinking stuff [20:12:42] larvacean [20:12:59] scottfrance leaves the room [20:13:53] zoom! [20:15:06] kaseycantwell leaves the room [20:15:12] keep an eye out with those strands - could be prayid siphonophores [20:15:43] the mucous is tricky [20:16:06] Hey Stephanie! [20:18:16] snow looks really thick again to me. Maybe it's just the movement of the ROV [20:20:00] I think this is dense [20:20:34] We could compare to the transects in GoMex, but this qualitatively appears to be dense [20:23:52] much thicker than Friday's dive. [20:26:32] suddenly much less dense marine snow at 794 m! [20:27:04] jelly! [20:27:42] where is the DSL? 500m? [20:27:57] inflated lobate ctenophore was very cool! [20:28:19] only caught a piece. Maybe Thalassocalyce? [20:28:28] mikeford leaves the room [20:31:15] seems to be fewer mucous strings outside of the sense particulate layer as well [20:32:17] Hi Dhugal! [20:32:33] This is Stephanie Bush on Kasey's account [20:32:48] good morning! 05:30 here [20:33:06] we got some midwater! [20:33:21] Yay! [20:33:30] excellent! [20:33:36] Hello Dhugal! Great to have you here! [20:33:47] you should call in and tell us about some jellies! [20:33:55] my screen is black. Are lights off? [20:34:04] oooh that was a radiolarian [20:34:37] another! [20:34:44] wicked [20:34:53] Dhugal are you watching the science feed? [20:35:07] ok. fixed. [20:35:18] Mike, yes, from what I can tell DSL ~~450-650 in 38 kHz, 500-600 in 18 - those are very rough, it's pretty hard to read the screen [20:35:34] Great [20:35:46] Thank you. [20:37:10] kaseycantwell leaves the room: Replaced by new connection [20:38:15] larvacean [20:38:27] genus Oikopleura [20:39:22] chaete [20:39:47] kaseycantwell leaves the room: Replaced by new connection [20:39:47] those guys... [20:40:12] oik discarded [20:40:32] chaetes x2 [20:41:14] nice catch. very cool. [20:41:27] ex-Radiolarin now snow? [20:41:41] Dhugal, we saw a great physonect, maybe Marrus from other transect [20:41:46] siph! [20:41:57] yes! [20:42:00] zoom on bell [20:42:16] Rosacea maybe? [20:42:22] can we get more contrast? [20:43:12] bells were cylindrical rather than conical and bracts looked quite rounded so probably Rosacea [20:43:30] ew. [20:43:42] Mesochordeus larvacean house [20:43:54] shrimp [20:44:04] yes, very round. [20:44:09] non-sergestid [20:44:40] those guys... [20:44:52] both my video and audio are really choppy so my chat is too [20:45:05] Cyclothone [20:45:18] my chat is a bit slow as well. video okay [20:45:32] siph!! [20:45:41] but you can talk too, Mike! [20:45:56] didn't get a great look [20:45:59] kaseycantwell leaves the room [20:46:33] can you spell that in chat? [20:46:48] bargmannia [20:47:01] thx! [20:47:12] looks like Bargmannia but only 1-2 frames in focus [20:48:38] going to go set some coffee to brew [20:49:45] excellent! Are there many collections with good siphonphore material? I have not checked, but I think most of our specimens are from shallow LT400m [20:49:55] ssiphonphore, sorry [20:50:11] ugh. siphonophore is the spelling I was going for... [20:50:57] @ all - stephanie's account and laptop connection is being troubleshooted [20:51:09] cool. [20:51:21] Can someone else please chat and shat whatever is said in the chatroom [20:51:33] because she will NOT be able to see it [20:51:40] okay [20:51:48] got it. [20:51:57] Amanda/Mike since you are on the line, if you could verbalize what is discussed here, that would be great [20:52:12] got it. [20:53:48] thanks [20:55:02] amandanetburn leaves the room [20:55:37] protist [20:55:49] lots of them [20:56:22] seen central mass well? Seemed quite small on the last one. If brown at centre could be a foram [20:56:59] unless you have seen proper spines and not just pseudopodia [20:57:32] seem to be really abundant though, as you say [20:58:36] spumellaria [20:58:38] scottfrance leaves the room [21:01:15] ctene? [21:02:22] protist [21:02:51] coelodendrid phaeodarian? [21:06:37] oik [21:06:46] does this tell us about silica levels? the sightings of these protists? [21:07:31] Nakamura and others document many taxa, but I always wonder about ecology [21:07:41] krill? [21:07:56] Could do but more likely their prey distribution perhaps? [21:08:02] shrimp [21:08:18] no-one knows! [21:08:31] that's great!!!!!! [21:08:44] well, mostly great. [21:09:56] Euphausia [21:10:34] Chauliodus [21:10:49] nice!, for a fish [21:11:05] foward angled dorsal fin [21:11:25] can u see shape of light organ under eye which would tell us species [21:11:57] sergestid [21:12:15] half-red [21:13:27] coelodendri phaoedarian [21:13:54] Desmophyes annectens [21:14:05] spherical somatocysts very clear! [21:14:18] can be either [21:14:30] depending on genus [21:14:46] Subfamily Prayiinae has 2 [21:14:59] Wow! [21:15:18] wow! [21:15:37] Vincuiguerria typr of thing that I don't think we see in Pacific. Very long pectorals? [21:15:51] Kick-*ss footage [21:16:46] that would be a great highlightl, but we typically don't highlight fish :) [21:17:08] u could highlight that chaete we just filmed ;-) [21:17:25] all chaetognath dive.... [21:17:41] so far Marrus, Bargmannia and that Desmophyes are today's highlights? And all the protists of course. [21:17:55] Cyclothone [21:20:01] looking for ctenophores! [21:20:19] lots of krill around. Seen any Solmissus? [21:20:33] yep - a few a little deeper [21:20:59] undescribed Solmissus I think [21:21:30] Cool! My net connection making this as choppy as a trip around Cape Horn [21:21:39] Dhugal -saw quite a few Solmissus on the White Shark Cafe. cruise off the Falkor. [21:21:45] better that way [21:22:13] @Amanda, were there heaps of salps as well? [21:22:28] amandanetburn leaves the room [21:22:42] lots of ctenos with Solmissus? [21:23:40] that means it is coffee time on land I guess [21:25:11] always coffee time on land. firing up the espresso machine now [21:25:55] ctdippid cteno [21:26:05] cydippid cteno that is [21:26:07] kaseycantwell leaves the room [21:26:13] ok am caffeined up now [21:26:23] yes!! [21:26:38] siph [21:29:01] were they fishing Lensia? [21:31:46] really? A Rhodaliid??? [21:31:54] yep [21:32:20] plain orange float or with stripes? [21:33:15] pinkish... not one I am familiarwith then [21:33:27] hatchetfish [21:33:41] krill [21:35:40] Hi Cheryl. Can u see chat? [21:36:01] Yes, I can see chat [21:36:34] siphonophore [21:37:16] cherylmorrison leaves the room [21:37:26] siph [21:37:44] lots of small transparent things becuase the illumination is brighter up this shallow [21:37:57] don't want to cast any shadows... [21:38:13] ha! good point, though [21:38:23] krill [21:38:29] amandanetburn leaves the room [21:38:48] first juvenile Chauliodus I have seen in situ [21:39:02] siph [21:39:15] on one of those previous transects [21:41:49] lights have been going on and off so transects not quantitative [21:42:05] right [21:42:18] start 300 m [21:42:44] having trouble with seascribe now- may just be a bad internet connection [21:43:13] can't wait to get a plankton camera on here to correlate the macro-organism distributions with their prey [21:43:14] amandanetburn leaves the room [21:43:28] yes!!!! [21:43:33] lobster larva?? [21:44:17] trichodesmium? very spiky and olive green. squink? [21:44:32] good call on that. I would agree [21:44:50] can't wait to see that in nice video [21:45:20] tricho if very small but otherwise squink maybe [21:45:34] squink? [21:45:49] squid ink [21:45:54] squid ink shorthand [21:45:58] squid ink? [21:46:11] hey hey midwater lingo dudes! [21:46:26] i love squink [21:46:29] another! Not squink. Something else... what I wonder... [21:46:46] probably a hundred cool squid species right behind the ROV [21:47:34] ghost prayid tail? [21:48:17] will be hard to get good contrast to look inside the jelly masses unless there is more side lighting [21:50:48] amandanetburn leaves the room [21:51:43] we probably have to live with the flare a little for the better lighting... [21:52:21] more of that pretend squink! Maybe actually is Trichodesmium [21:52:46] is it oligotrophic at the surface? [21:53:03] ddont think so [21:53:12] Have never seen tricho at depth before [21:53:28] those deserve another look [21:53:42] definitely. And the protists as well [21:53:51] 21:53: UTC end 300 m transect [21:54:04] could almost get quantitative data from them because there were so many [21:54:14] of course you saw squid ink while I was at dinner ! (steph btw) [21:54:24] always so interesting to see new places [21:54:55] Do we know that the organisms we are calling radiolarians are radiolarians? Leslie was asking me how I know they aren't forams [21:55:04] Thanks everyone [21:55:24] we need to look at the center mass in a bit more detail post dive to confirm that specific difference. [21:55:32] they seemed to be radiolarians based on the large diameter of the central mass [21:55:44] Thanks for joining! [21:55:55] couldn't see an off-center brown mass within the central mass so don't think they were phaeodarians [21:56:05] Thanks Dhugal [21:56:20] thanks everyone. see you at the next midwater dive [21:56:27] also couldn't really see the spines though... [21:56:27] mikeford leaves the room [21:56:36] Thanks everyone! Talk again soon! [21:56:52] ok thx all [21:57:00] Good start to a monday morning!
