[14:00:43] mattdornback leaves the room [14:03:48] Cyclothone [14:05:24] danielwagner leaves the room [14:07:27] Siph for Dhugal to look at later... [14:08:50] iscwatch2 leaves the room [14:13:56] iscwatch2 leaves the room [14:16:20] Hi all -just checking - is this the chat for today's (4/20) dive? [14:16:59] iscwatch2 leaves the room [14:17:38] @traceysutton: Yes, it is! [14:18:22] thanks, Adam. It looked like people joining, then leaving, plus some bits from end of yesterday. just checking. [14:20:25] nickpawlenko leaves the room [14:21:58] For general info WR488 is currently leased by a subsidiary of StatOil, the Norwegian national oil company. They have some leases on other surrounding blocks. StatOil often works with Total, the French national company [14:22:04] Yes, Tracey great fish yesterday. Thanks also for the email with the IDs. [14:23:28] I'll look forward to looking back. Happy to look at pix any time - thank YOU. Marking some targets on way down today to look at later. Nice ceph. [14:25:16] Exceelent Tracey. I will sieve through the photos as well, and if it is OK with you, send you the better ones for help with identifications [14:26:10] Please do. Thanks. [14:27:44] danielwagner leaves the room [14:30:20] nickpawlenko leaves the room [14:30:25] danielwagner leaves the room [14:36:14] danielwagner leaves the room [14:36:28] that pyrosome looks like it has been trawled... [14:37:09] mattdornback leaves the room [14:42:32] EX1803_DIVE07 ROV on Bottom [14:43:12] Do my eyes detect bamboo corals in the sediments...? [14:43:16] yes [14:43:25] Hello all [14:46:11] Hi Asako [14:46:16] I just logged on. Was there a good ceph on descent (based on Tracey's comment)? [14:46:39] Hi Tina! [14:48:56] Mike, nice octopod(?) at 09:53:49. [14:49:32] Thanks Tracey for catching it. [14:50:46] @scott, these bamboo? how they hold at soft substrate? by roots or at something solid? [14:50:54] students arriving in the ISC [14:51:23] lovely jelly by the way [14:51:27] is current 'zero' over this structure? [14:51:40] mattdornback leaves the room [14:52:02] Cool welcome Boston College! [14:53:51] bcclass1 leaves the room: Replaced by new connection [14:55:12] Well a good start so far! [14:55:41] @Tina: don't know if you heard audio, but this species can form roots, much like Acanella. [14:55:47] bcclass1 leaves the room: Replaced by new connection [14:55:57] Hello all! [14:56:03] Hi Nick, we're at the Inner Space Center. Looking forward to today! [14:56:36] It may be worth noting that this may be the species that was intended as the type of the genus Lepidisis, i.e. Lepidisis cayophyllia, originally described from the deep slope off New England. [14:56:38] bcclass1 leaves the room: Replaced by new connection [14:57:18] @scott, I was asking, if you have seen ever unbranched forms with rhizoids. Definitely I know Acanella. This tear we have collected one unbranched with rhizoids - but alas no polyps left [14:57:43] NICK, as suspected, you can't log in with one account on multiple machines. I need 4 more logins please when you have a moment [14:59:03] @Tina: yes, we have seen (and collected) unbranched isidids with rhizoid rootlets. [14:59:41] @scott, any particular clade or they scattered? [15:00:02] it is tail my guess [15:00:08] By the looks of the sea floor, this is one animal that does not mind walking around in its own poop... [15:01:15] does look a bit like a dog park [15:01:22] yes, I also love the translation of scott's point [15:01:25] @Tina: so far in one clade - the "I1/I2" clade, which we are still trying to determine whether it should be Lepidisis or Isidella [15:02:35] @scott, I will try to pass you a fragment what we collected, may be some DNA left [15:02:46] @Tina: if my memory is correct, Isidella has precednce, but we have not been able to actually find/collect a specimen that matches the original description. They all seem to be misidentified! [15:03:41] fly-trap basket [15:04:16] plastic bag [15:04:17] @Tina: I mean that we can not find an Isidella that matches the original description. [15:04:18] asphatlt? [15:04:52] Cup coral [15:04:54] bag? [15:05:12] @scott, where the original Isidiella came? [15:05:14] I can't believe all these animals could grow to this size on a bag... [15:05:27] asphalt it is! [15:05:35] or might that just be a retracted zoanthid? I can't tell what those yellow nubbins are. [15:05:56] bcclass5 leaves the room [15:06:37] @Steve: I think zoanthids [15:06:44] @steven, anemone my guess... [15:07:01] anemone or zoanthid. too deep for cup corals to be common [15:07:23] @Tina: I think Isidella elongata from Mediterranean. But every specimen of I. elongata we have examined has turned out to be an Acanella! [15:07:33] susanhaynes leaves the room [15:08:05] iscwatch2 leaves the room [15:08:36] @scott, there are not many solitary zoanthids [15:09:10] @Tina: good point! Maybe these are some young hormathiids or other related anemones with thick walls. [15:09:36] @apparently another species with smooth cuticule [15:10:12] we have one with tubercules and pink and another yellowish and smooth [15:10:17] This bamboo coral has seen better days... [15:10:53] adamskarke leaves the room [15:11:45] bcclass9 leaves the room [15:12:16] bcclass10 leaves the room [15:12:26] actually it is another species of holothurian [15:12:27] andrewshuler leaves the room: Replaced by new connection [15:12:38] bcclass8 leaves the room [15:13:38] fernandoaragon leaves the room [15:13:39] allencollins leaves the room [15:16:43] allencollins leaves the room [15:18:02] too stright... [15:18:39] fish mimiking bamboo... it did not know that we are interesting in bamboos [15:19:10] know what the eel is Tracey? [15:19:43] looking now [15:19:55] Nemichthys? [15:20:05] not a snipe eel [15:20:35] @danielwagner we have Kamaja Elmore today from Georgetown High School helping in the Charleston ECC at HML [15:20:41] not witch? [15:20:56] roger that andrew [15:21:18] hope we get another black diamond cydippid today... [15:21:36] a nettastomatid, I think (with eel) [15:21:41] witch eel [15:21:50] Was it a Nettastomatid? [15:22:26] iscwatch leaves the room [15:22:38] I don't think it was a Nettastomatid based on the well developed caudal reagion [15:22:47] I was told, it is hard to get a witch eel in net with head for some reason... [15:23:25] I wouldn't get in a net with a head either... [15:23:26] agreed - that caudal fin is what is stumping me... [15:23:58] Just when I think I'm learning my fish families... [15:24:04] Yeah, it was continuous with the dorsal & anal fins but well developed! [15:24:50] sometimes they 'regrow' a caudal fin after a bite, which is common. My screen shots were all head - no caudal [15:27:00] adamskarke leaves the room [15:27:31] half-eaten bamboo [15:28:16] Where is the guilty sea star? [15:29:14] allencollins leaves the room [15:29:14] it was something sitting at smaller specimen [15:30:15] best guess for eel is Nettastomatidae (Hoplunnis ?), but super tentative. Kevin is right, caudal fin was weird. will look at images to count lat line pores. [15:30:43] Did anyone notice the presence of a pectoral fin on the eel? [15:30:57] I did not [15:31:22] This one is wearing lipstick... [15:31:37] Spiny eel [15:32:08] Polycanthonomus? [15:32:14] Polyacanthonotus merretti [15:32:40] nice one [15:32:41] Polyacanthonotus merretti was captured on D2 in December 2017 [15:33:26] No it was physically stuck on D@ [15:33:30] D2 [15:34:00] one of few fishes that eats hydroids [15:34:07] something for Ghigal) [15:35:03] @Tracy: great info. I'm always looking to learn about the predators of deep sessile cnidarians. [15:35:44] @scott, better to look for predators of predatory seastars... [15:36:04] catalinamartinez leaves the room [15:36:18] could be incidental while picking off mysids, polychaetes, amphipods. Prob makes living off those stalked "communities" [15:36:19] susanhaynes leaves the room [15:38:01] I would imagine those communities would be a good draw for many predators/omnivores, but seeing it is the hard part! [15:38:11] very degraded exoskeleton? [15:38:28] is it trash [15:38:31] plastic bag? [15:39:21] ipnops murrayi [15:40:21] allencollins leaves the room [15:40:49] I always wonder 3hat that fish thinks is happening when it is lit up... [15:40:53] Yes [15:41:16] Poor think is hopefully only temporarily blinded! [15:41:24] thing [15:42:05] According to Herring, they should be able to recover. [15:44:06] The eyes are degenerated on Ipnops so hopfully so! [15:45:49] kensulak leaves the room [15:46:49] hat are these white things? [15:47:33] can we zoom? [15:47:38] kensulak leaves the room [15:48:15] bubble excavation? [15:48:22] cool little dome, maybe cored by hydrate...has that morphology...sorry i'm on another call so not on telecon right now [15:48:51] trashing worm [15:50:42] Look for pectorals fins. [15:51:40] adamskarke leaves the room [15:52:06] excellent - thank you [15:53:04] Venefica procera, I believe [15:53:47] thanks! [15:53:53] the process on the snout is the tell... [15:54:10] Agreed! [15:54:21] why do the eels hover diagonally? [15:54:28] great shots - thanks [15:54:44] I do think tail has been bitten... [15:55:53] That is an awesome job of regeneration! [15:56:12] it was acting like a coral stalk when we first saw it - upright. Maybe that is the norm and we we disturbed it? [15:57:49] My personal hypothesis on the head-down position is that they are "sniffing out" benthic prey, or being in position to grab things that swim up from the bottom. I suppose stalk mimicry is a possibility. [15:57:56] white circle on it in the middle? [15:58:05] Great question...It could be as Tracey states...mimicry either for predator avoidance or to camouflage for foraging! [15:59:24] At some places there are many bits of "tar skin" that look like shredding plastic bags and even old burst intertubes! [16:02:05] Whoa! [16:02:49] Benthothuria [16:03:16] beautiful coloring! [16:04:07] are those suckers on the bottom? [16:04:16] Benthothria has a very tough and thick bodywall [16:05:13] below on bottom is Benthodytes lingua and Benthodytes typia [16:05:26] danielwarren leaves the room [16:05:38] andrewshuler leaves the room [16:08:32] I am momentarily stumped... [16:08:37] echinoid test? [16:08:39] coconut? [16:08:54] just echinoid [16:09:17] @Tina: you think an irregular urchin? [16:09:24] are sea apples deep sea species? [16:09:35] maybe a sea biscuit type schinoid [16:10:05] @Lauren: is a sea apple like a sea potato? [16:10:17] @scott, I think something like Brisaster [16:11:17] I think we are converging on irregular, or burrowing, urchin [16:11:32] i think what you call a sea potato is what i've called a sea biscuit?... i'm not familiar with those species at all - just see them occasionally [16:12:13] @scott, you are probably right on the urchin [16:12:41] @Lauren: yes, there are deep-sea versions of these. We don't often see them because they burrow. When we do they are usually dead, and just the "shell". [16:13:27] @Lauren: to clarify, sea apple, sea potato, sea biscuit: these are all common names for burrowing "irregular" urchins... [16:13:30] fish [16:13:42] "Irregular" because the shell is not perfectly globular. [16:13:44] my favotit) [16:13:56] Halosaur? [16:14:12] yes halosaur [16:14:28] The fish cavalry have arrived! [16:14:32] ;-) [16:14:59] potentially Aldrovandia oleosa [16:15:18] yep, snout looks naked. Lovely. [16:18:05] ooh, Cyclothone! [16:18:37] Yes - A. oleosa, but a very small juvenile. Dark color, cavernous LL canals on head = A. oleosa, but snout rather long - as in a newly transformed juvenile [16:18:42] kensulak leaves the room [16:19:04] and these people do not letus to pock corals [16:19:07] I'm on the high res video, but it seems to be rather delayed compared to the audio today...anyone notice this as well? [16:20:23] Poyacanthonomus merretti [16:20:28] ? [16:20:33] polycanthonotus [16:21:29] does she mean medicines developed from deep sea species ? [16:21:51] That 'might' be Notacanthus, but it may also have had its spines down... [16:22:19] siboglinids and synaptid holothuroids [16:22:22] pretty sure Polycanthonotus maybe merreti or challengeri [16:22:34] are the curliecues siboglinids? [16:22:46] holothuroid is Chridota heheva [16:22:54] I'd take your word for it, for sure. [16:23:18] these have been previously found at GoM seeps [16:23:35] hi cara here clarifying the question. we were wondering about naturally occurring viruses and their role in deep sea ecology. We know they might have to do with interaction with microbes, but we were wondering if someone could expand on that [16:23:48] the spaghetti type orgs might be siboglinid polychates [16:23:56] but that is just based on nose shape-didn't see the dorsal. hoping ken can confirm [16:24:51] @bcclass2 I don't think we know much about marine viruses in the deep sea [16:24:59] amphopod not chemo...nor are the holothuroids...curly worms are [16:25:00] @Amanda: copy that - just passed on that observation. [16:25:05] roger - I think your right - was very slender with long snout. they always look so happy. [16:25:25] all notacanthids observed this dive = P. merretti, notable character being the distance between anterior and posterior nostrils => eye diameter [16:26:03] the swarming crustaceans look like more like copepods [16:26:08] why do the cucumbers have spotted patterns? [16:26:38] earlier nettastomids = Venefica procera, with fleshy process at tip of snout. Caudal region of last specimen was atypical, looks to have been bitten and regenerated [16:26:51] spots on cucumbers are ossicles (spicules) in this animal they are wheel shaped [16:27:00] @scott, thanks :) [16:27:04] thanks ken [16:27:45] if eyes were made for seeing then beauty is it's own excuse for being...or something like that [16:27:48] црфе шы ерфе ишмфдму? [16:27:56] sorry [16:28:05] what is that bivalve? [16:28:29] nice bob [16:28:40] Rhodora by Ralph W. Emerson [16:29:14] kevinrademacher leaves the room [16:29:25] If the sages ask you why your beatury is wasted here on Earth and Sky [16:34:43] adamskarke leaves the room [16:36:12] @Bob: I like it. I'll start out with thta next time. [16:36:42] Or we could ask: why is the default position that they not be pretty? [16:42:13] records of Polyacantonotus merretti from this dive are the deepest yet at ~~2180m. Previously known down to ~~2000m. Going deeper, this species is replaced by P. challengeri, a species of the continental rise down to ~~4000m, which is very similar, gets larger, but has the nostril openings very closely set [16:43:26] Is there sexual dimorphism between snout length in male and female halosaurs? [16:46:28] no sexual dimorphish in snout length, but there is in pigmentation of the top of the head and nostrils, both getting darkly pigmented in mature males. The halosaur seen a few minutes ago has a long clear snout, looks like another early juvenile, but perhaps of A. phalacra based on gray body color. Species ID uncertain for this specimen [16:47:20] cutthroat eel [16:47:24] synapobranchus [16:52:37] adamskarke leaves the room [16:53:17] michaelvecchione leaves the room [16:54:41] going back to your previous statement about P. challengeri replacing merretti, what adaptation does the challengeri have that allows it to live at those greater depths? [16:56:20] Aldrovandia [16:56:25] Large, heavy-bodied synaphobranchid just seen looks odd. Prominent white LL pores are like Ilyophis, but body is too thick relative to head for most Ilyophis species. Lower jaw looks shorter than upper, like Ilyophis. Need to study the frame grabs later, possibly a different genus other than Ilyophis or Synaphobranchus [16:56:48] thanks ken [16:58:07] bcclass1 leaves the room: Replaced by new connection [17:00:15] bcclass1 leaves the room: Replaced by new connection [17:01:25] bcclass2 leaves the room: Replaced by new connection [17:01:57] bcclass1 leaves the room [17:03:16] cerataspis [17:03:40] At least 3 purple sea cucumbers here maybe a 4th [17:05:03] adamskarke leaves the room [17:05:33] Coryphaenoides rudis [17:07:25] hey, come back from a meeting and there's a fish. nice job, folks... [17:08:14] Hepomatus [17:09:39] bcclass1 leaves the room: Replaced by new connection [17:10:24] bcclass2 leaves the room: Replaced by new connection [17:10:33] Cataetyx laticeps [17:11:34] bcclass2 leaves the room: Replaced by new connection [17:11:35] have to go, will try to join you in 2,5 hours [17:11:47] thanks tina [17:14:11] tinamolodtsova leaves the room [17:15:15] bcclass2 leaves the room: Replaced by new connection [17:15:39] Benthodytes typica very pale but not uncommon...gut empty [17:17:43] that midwater fish was Cyclothone obscura [17:19:07] bcclass2 leaves the room: Replaced by new connection [17:19:29] I cannot hear any science on the video or OkEx line. Are you muted? [17:19:54] Oh, I hear now that there is an interaction going on. Sorry about that. [17:20:34] bcclass1 leaves the room: Replaced by new connection [17:20:37] These must be lamellibranchia...? [17:21:16] At the least, they are vestimentiferan tube worms [17:22:31] Only a few cm of Lamellibranchia extending from mud...old group that has been heavily sedimented in [17:25:30] bcclass1 leaves the room [17:26:17] holo Chirodota heheva...seeps and shipwrecks [17:26:56] bcclass1 leaves the room: Replaced by new connection [17:28:26] we've seen a couple floating sea cucumbers so far, is there any specific reason that they'd come up off of the bottom? [17:29:58] One expalnation is that it is a quick way to move from one feeding area to another... [17:30:19] If you exhaust the resources (the organics in the sediment), move to somewhere else. [17:30:31] We have seen 2 different species come of bottom this dive. The animals are nearly neural buoyancy some are escape swimmers. Others may disperse to find places where food is settling [17:30:34] Avoiding potential predators is another explanation [17:30:49] thank you [17:31:01] This Benthodytes is handing head down [17:31:57] old url https://oceanexplorer.noaa.gov/okeanos/explorations/ex1202/logs/apr24/welcome.html [17:32:17] The post is about Holo buoyancy [17:32:41] Was it swimming backwards?? [17:33:31] The swimming wasn't directional...just up by flexing [17:33:35] Aldrovandia [17:35:53] stevenauscavitch leaves the room [17:38:49] another BC question: over the years of exploration, have you noticed any visual indicators or effects that you think may be due to climate change? maybe specifically with deep sea corals? [17:39:38] lasers plz [17:39:47] Prof. Olins here with a message to any of my students back at BC. Hopefully you all are watching the video feed. Feel free to enter any questions you have in the chat room [17:40:49] Lamellibranchia "roots" can be much longer than exposed tubes and can "mine" sulphide from a large volume of sediment/rock [17:41:10] I can't say that I have seen any direct visual impacts... [17:41:51] are the lasers on? or are they being turned off during transits? [17:42:11] And I think the time scales of our deep-sea visual observations relative to the rate of climate change is so different that we may not see anything. [17:42:27] Daniel is discussing the likely most immediate affect: change in pH. [17:43:52] most recently seen Aldrovandia is A. gracilis, very white-silvery body, transparent top of head, long snout, 1 LL scale per each 3 body scales horizontally - nicely able to count in stop frame of video close-up [17:43:57] Another impact will be if the poles become much warmer it will affect thermohaline circulation, which will interupt the input of oxygen to the deep ocean. [17:44:38] To Professor Olins: here reporting from BC, will respond with any questions, students interested in climate change pH and impact on calcification processes [17:45:03] While deep GoM has been sampled since 1800's observations of corals is really much newer due to advancement in surveying and ROV technology [17:46:32] Reminder to turn lasers on when not doing beauty shots... [17:46:58] can we zoom in here? [17:47:22] this looks like a mixture of tubeworms [17:47:36] any more zoom? [17:47:43] adamskarke leaves the room [17:48:12] Are the swimming bits larvae? [17:48:23] I'm really confused by these. Looks like Sclerolinum with some other tubeworms between, [17:48:27] BC class here wondering what the small white organisms swimming around are? [17:48:34] is there any chance we could collect a clump? [17:48:38] note to at sea scientists and ROV tech crew - if you encounter another Ipnops with those glaring cream-yellow flattened 'eyes' (spread out pigmented retina under transparent frontal bones) - would it be possible to keep the animal in view and turn off the lights for 5-10 sec? Lingering unresolved question is whether or not those highly reflective retinas are use to project bioluminescence. That is, do those eyes light up? I have never been in the situation where this question could be addressed. Work by Ole Munk in Denmark long ago showed that the flattened retinae have few photoreceptive cells - so why this peculiar adaptation? [17:49:06] not sure what the larger tubeworm species is.... Escarpia maybe? [17:49:08] what are those clear, empty tubes? dead tube worms? [17:49:47] that was weird. [17:50:11] I believe that Erik Cordes sampled these during the Chemo-III project. I do not know what has been woked up [17:50:26] worked [17:50:33] NO! [17:50:36] not hydroids. [17:50:55] Sclerasterias? [17:51:02] @bob: yeah maybe but would be good to get some more that would be available to community. [17:51:06] @diva, we saw them earlier and Scott made sure to clarify that they were sibos [17:51:37] they are a really strange tubeworm that show great adaptability living in a variety of chemo habitats. [17:51:40] @bcclass: I'm seeing bits of mud stirred up by the ROV that look like swimming animals, but are not. [17:52:02] bcclass2 leaves the room [17:52:08] @scott: i think they were referring to the small white crustaceans that look like copepods [17:52:10] Yes, so strange that sea star was feeding on tubeworms.... [17:52:29] @amanda: thanks for clarifying [17:52:44] a cold seep thing [17:53:00] @dive- i try [17:53:48] can we zoom on the crab? [17:54:20] Sclerasterias tanneri very common in upperslope mussel communities...not white. [17:55:12] how does this sort of thing happen?? [17:55:21] is it a homolid? [17:55:31] hermit crab in tubeworm tube fragment [17:55:33] Now there is a novel use of a tube! [17:55:48] Okay here is my pitch to collect some Sclerolinum as there seem to be a lot here: they are a strange siboglinid that show great adaptability to different chemo habitats with a range of fluid seepage. They also occupy great geographic ranges: arctic all the way down to antarctic. Very little known and may be multiple species here in the Gulf [17:56:15] very likely new species of crab...they can be house specific [17:56:34] Looks like it is holding a piece of wood [17:58:29] have you encountered Bathyphysa conifer? [17:58:44] I think it's two species that we keep seeing. Sclerolinum are the super skinny curly ones. Ramen-looking. But there is also a bigger white species in between those bushes. [17:58:45] bcclass1 leaves the room [17:58:47] sure collect some of the curly tubes [17:59:54] divaamon leaves the room [18:00:14] Diva, which one of the 2 spp. are you more interested in? [18:00:44] Thank you guys! Only if possible but would help the chemosynthetic-research community [18:01:14] @daniel: the very skinny curly ramen ones that form the 'bush'. [18:01:24] got it [18:02:08] @dan: if you do end up collecting, you will likely just have to grab a bush and just pull. Tubes are normal chitinous so not 'brittle'. [18:02:25] got it [18:02:34] iscwatch2 leaves the room [18:02:34] bcclass5 leaves the room [18:02:34] bcclass6 leaves the room [18:02:35] bcclass3 leaves the room [18:02:37] bcclass4 leaves the room [18:07:29] Only link to previous discovery...mainly deals with the holothuoid. https://oceanexplorer.noaa.gov/explorations/07mexico/logs/june18/media/pogo_cuke_600.html [18:13:56] I have to step away from the phone for 45 minutes or so. [18:14:09] roger scott [18:14:46] scottfrance leaves the room [18:15:43] @bob: Wow, that is from 2007! [18:16:02] kensulak leaves the room [18:18:47] not sure what the midwater fish near the bottom was... [18:19:10] chaetognath [18:19:30] Good view here of the aneomne we imaged a few minutes ago, but this one expanded. [18:19:54] stevenauscavitch leaves the room [18:22:15] elizabethurbangedamke leaves the room [18:26:52] amybowman leaves the room [18:27:29] nolanbarrett leaves the room [18:29:25] iscwatch leaves the room [18:30:24] We saw these in December. A very heated debate ensued whether they were geological or biological.... [18:30:36] I think we concluded geological. [18:31:18] We also vacillated [18:31:24] apparent fecal material in hole [18:31:27] Reminder for lasers during ttransit... [18:31:44] @bob, yes, they looked like fecal casts to me as well [18:33:54] the ones we saw had actually been periodically extruding sediment-laden water. Very strange. [18:34:01] Must sign off...maybe there was seepage here until holothuroids clogged plumbing [18:34:13] :) [18:34:23] robertcarney leaves the room [18:37:54] bcclass1 leaves the room [18:38:10] adamskarke leaves the room [18:38:49] colleenpeters leaves the room [18:39:04] May I suggest that if in the last hour of the dive we have not maxed out our collections, we take a clipping from a bamboo coral whip as the dominant fauna of the dive. [18:39:39] this one is full or gravid [18:39:41] roger that scott [18:40:07] and has been bitten, probably by a shark [18:40:12] anyone in particular scott? [18:43:06] So far they have all looked the same to me. There is no hurry. I think you can wait until last hour, just in case you come across a glorious area of new taxa! [18:44:03] Wait a minute.Am I talking you out of collecting a bamboo coral?! ;-) [18:44:44] Actually, an interesting idea would be if you found a small colony and could pull it out of the sediment... [18:44:55] ...then you might get the rhizoid rootlets. [18:45:13] Note: I am in a seminar and so have no audio. [18:45:40] is this an OK to sample? [18:45:47] scott [18:45:56] Yes, this looks good to me. [18:46:30] But not as a "small" colony. Looks too long to pluck... [18:46:40] ...and fit in biobox, so just a clipping from the top. [18:46:44] 8-10" or so [18:46:54] Be sure to get a couple of nodes. [18:47:13] Beauteous! [18:47:32] Thanks team. [18:49:43] amybowman leaves the room [18:52:22] not sponge, closed anemone [18:52:50] agreed about debris [18:58:28] scottfrance leaves the room [19:00:52] iscwatch leaves the room [19:01:52] adamskarke leaves the room [19:08:34] adamskarke leaves the room [19:09:57] stevenauscavitch leaves the room [19:11:40] I think this is the species for which we made the collection. [19:12:14] I think my English is failing me. [19:15:20] Yes! Sclerolinum! [19:15:35] oooooh! [19:16:17] The amphipod clouds are fascinating to me. [19:16:38] As I noted earlier, the only other clouds I am familiar with are from hydrothermal vents. [19:16:43] @diva--are you on the telecon line? Adam is asking if you want him to sample here and what to sample [19:17:06] @Diva: have you seen these amphipod swarms before at seeps? If so, has anyone collected and IDed? [19:17:38] ooooh pycnogonid! [19:17:44] Yes sample! [19:17:48] not on phone [19:17:53] @diva--you will need to tell them what to sample [19:17:57] Yes, Diva indicated earlier she would love a sample of curly-cue worms. [19:18:00] Go for it. [19:18:16] I would reach for a chunk of the mass of curlies. [19:18:21] red patch of curly worms [19:18:25] exactly! [19:18:53] @scott: copepods, yes have been known from seeps but not sure about sampling record [19:20:02] @scott: we saw them around lamellibrachia bushes in Dec [19:20:09] Copepods! REally. [19:20:27] @scott, yes, harpacticoids [19:20:37] @Diva: you are reminding me that we had this same argument/discussion/impassioned debate before! [19:20:40] :-) [19:20:54] Exactly! [19:21:08] Copepods! Amphipods! Copepods! Amphipods! Copepods! Okay, you win: copepods [19:21:16] :-) [19:22:20] the copepods could also be leptostracans, we collected a bunch with some of our samples in the atlantic seeps [19:23:29] @scott, based on what Jill wrote, we shall see, I hope :) [19:24:15] jonathanjackson leaves the room [19:24:28] Leptostracans would be as cool as amphipods. Clouds of Dahlella calderiensis from vents have eyestalks modified to scrape bacteria from rock surfaces. [19:24:54] copepods are pretty cool, too, but i don't want to fight over chat [19:24:58] Gotta run, but will call in fo rthe midwater planning call. Thank you. [19:25:24] traceysutton leaves the room [19:26:39] i think manips will be better [19:27:31] squeeze! [19:28:19] good collection [19:28:23] jillbourque leaves the room [19:28:30] that looks fab! [19:29:16] THANKYOU [19:29:45] Great stuff. [19:29:57] Bet you'll have fun going through that mass for associates! [19:31:45] @scott: Yes, that one might take a few hours..... [19:32:15] michaelvecchione leaves the room [19:32:37] susanhaynes leaves the room [19:35:42] elizabethurbangedamke leaves the room [19:40:41] Pseudomorph? [19:47:17] In the case of this species, the polyps are also pretty flexible aling their length so at the polyp level they can alter their position with respect to current. [19:47:24] *along [19:48:55] cataetyx laticeps [19:49:05] the fish had parasites [19:55:39] Holothurian ballerina... [19:56:03] "Look Ma! No Hands." [19:56:12] "I mean, tube feet" [19:56:27] Deep sea Macy's Day Parade... [19:56:40] I can go on all day... [19:56:47] williamkiene leaves the room [19:57:06] keep em coming scott [20:05:16] Long live the SeaPoke. [20:11:25] Okie. I'm signing off for the evening. Thanks for the awesome collection, Okeanos team! Really exciting! Hope the rest of the dive goes well. [20:11:29] divaamon leaves the room [20:12:02] Thanks Diva! [20:12:19] We need to find a dead bamboo coral in the next minute... [20:12:30] Then we can pull it out to find roots. [20:13:25] carolynruppel leaves the room [20:16:47] We did also image a sea pen, to be fair.
