I am hearing everything echoed/repeated on the video feed. [13:44:25] Sorry - ignore that last comment. I had two streaming windows open. Is it going to be that kind of a day? [13:45:32] scottfrance leaves the room [13:45:42] adamskarke leaves the room [14:06:25] adamskarke leaves the room [14:11:45] adamskarke leaves the room [14:31:09] adamskarke leaves the room [14:31:22] ETA on bottom ~~10 CT [14:32:20] Update: Science call will begin at 9:45 AM CDT [14:35:38] paullarson leaves the room: Replaced by new connection [14:39:54] adamskarke leaves the room [14:40:00] nolanbarrett leaves the room [14:44:59] nolanbarrett leaves the room [14:48:40] Standing by for engineering [14:48:59] call will start momentarily [14:49:10] adamskarke leaves the room [15:06:09] EX1803_DIVE14 ROV on Bottom [15:13:54] Looks like a small Anthothelid... [15:16:12] there's a stalked maybe bryozoan to the right of this black coral [15:17:30] bramble keratoisis [15:20:24] stalked tunicate (Culeolus sp.). [15:24:51] Go for it [15:25:06] @Dan what is the name of this coral? [15:25:12] If this is Bathygorgia (and, as Daniel notes, it does have characters that make it look like such), this would be the first record outside of the central and southwest Pacific. [15:25:15] Bathygorgia [15:25:31] thanks! [15:27:15] Paramuricea [15:28:11] hi everybody [15:28:20] G'day Tina. [15:29:59] Charles messing was looking for those [15:30:22] chuck wanted the stalked crinoid [15:36:15] Schyzopathes or Telopathes? [15:36:26] Telopathes [15:37:50] Some appear to be Bathypathes-like [15:38:09] it gets long it it is not broken at the top [15:38:15] Barnacles at the tip of the tip of this bamboo coral [15:38:33] @Enrique: yes, Telopathes looks just like Bathypathes before it branches [15:39:15] I meant they looked fleshier [15:40:24] @enrique, there are two species here. one with subopposite pinnules and another with alternated. the one with alternated is more fleshy. [15:40:51] Tuft of sponge spicules [15:42:46] the one with subopposite pinnules is more... classic for Bathypathes. for some reason it may appear to be Telopathes, that apparently .. problematical species in terms of morphological differences [15:43:01] genus [15:46:17] tinamolodtsova leaves the room [15:46:38] @Enrique: soryy I misunderstood. My experience with Telopathes is it is more fleshy. As Timna is alluding - they can be difficult to separate morphologically. I think it was the genetics that initially pointed to Telopathes being distinct from Bathypathes (I mean distinct at genus level) [15:46:58] paullarson leaves the room: Replaced by new connection [15:47:53] upper part of Chryso is dead [15:48:05] It does look like a possible cirrate octopod egg. [15:48:18] thank you scott & tina [15:49:16] @scott, yes, they used genetics... supposed to be closer to Stauropathes, then Bathy... [15:50:03] Ipnops [15:50:33] @Tina: I should remember: Mercer first did the work in my lab! [15:51:24] paullarson leaves the room [15:51:45] nice dan! [15:53:18] tinamolodtsova leaves the room [15:54:04] Irido? [15:57:41] it has sclerites.... but they seems to be too small to be Kophobelemnon... [15:59:53] @Tina: I have such a hard time with the sea pens like this. I suppose it could be a young Anthoptilum...? [16:00:29] @Tina: the primary polyp tissue looked to me thicker than the typical Anthoptilum. [16:01:47] @adam carbonate rock? [16:02:37] @scott. it is not like I admit it to be Anthoptilum. [16:03:03] mikeford leaves the room [16:03:12] Anthoptilum has no sclerites visible with ROV - that is a good clue [16:03:22] @lauren - yes [16:03:51] @Dan: I meant to send you this link earlier (and to anyone else who wants to see the earlier tunicate that was disguised as a sponge): https://www.ncddc.noaa.gov/okeanos-animal-guide/Tunicata014.html [16:04:12] there is Sclerobelemnon but it is supposed to be shallower [16:04:23] @Tina: so are you saying you prefer ID of Anthoptilum for last sea pen? [16:04:35] @Tina: agreed on Sclerobelemnon. [16:04:54] @Tina: we need to create a new image database of sea oens referenced to actual samples! [16:05:02] *sea pens [16:05:13] @scott, no, I just thought that Kophobelemnon usually has more sclerites [16:05:58] ... so I do not know what it was [16:07:07] Adam: did I interpret last comment to mean that crinoid was not collected with the rock? [16:08:12] Crinoid was collected with rock, but may not survive trip to the surface since it is in the rock box rather than one of the bio boxes. [16:09:49] another Chryso [16:12:32] I have to leave you for 10-15 minutes, send me a shot if there is something interesting. [16:16:01] pig nose sponge [16:19:33] adamskarke leaves the room [16:21:13] Thanks, Dan! [16:28:15] tube anemone or anemone? [16:28:28] Ceriantharia [16:28:54] somebody has shots? [16:34:33] @Daniel. Where is Dive tomorrow? [16:35:34] Pourtales Terrace [16:35:44] @tina I have a great shot of the ceriantharid if that's what you're talking about [16:36:19] @rachel, it would be great if you can share) [16:37:21] he wants 10-arm stalked... [16:38:11] @Tina here's a google drive link. Let me know if it doesn't work.https://drive.google.com/open?id=1bfS9v97T-fAxsqitH6acL8jR4zxoVjvZ [16:39:00] Not sure what I was looking at there... [16:39:07] Sponge? [16:39:37] I think I just saw the first fish of the day dart away. [16:40:30] meganmcculler leaves the room [16:40:30] That sea cucumber needs more pteropods. [16:40:42] fish) [16:42:01] what about current speed? [16:42:31] amybowman leaves the room [16:44:56] chat-admin leaves the room [16:45:21] .... thanks Rachel. got it [16:48:38] Thta was an unusual looking crinoid... [16:48:41] hm... it is what chuck asked about or juv? [16:49:23] I don't hear any audio... I think the ship is no longer on the OkEx call... [16:50:18] Yup. The ship is definitely no longer on the phone call. [16:50:27] tinamolodtsova leaves the room [16:51:37] laurenjackson leaves the room [16:52:07] adamskarke leaves the room [16:52:07] danielwagner leaves the room [16:52:07] nickpawlenko leaves the room [16:54:02] Just checking again for confirmation that the ship knows you are off the call... [16:54:11] Okay, just heard you say so on the video. [16:56:29] fish in background? [16:57:03] maybe seeing things [16:57:22] amybowman leaves the room [16:58:19] I can hear you on the call again. [16:59:38] amybowman leaves the room [16:59:43] scottfrance leaves the room [17:00:56] amybowman leaves the room [17:02:55] what is the scale? [17:03:34] lasers 10 cm. Coral was ~~10cm x 10 cm [17:04:52] I will be sending screen shots of this to Joana Xavier [17:06:26] @Dan You're welcome! [17:06:53] tinamolodtsova leaves the room [17:09:39] we have more sedementation and animals only at cleared surface [17:09:50] Acanella-like on right [17:11:51] @Dan Speaking of the medicinal importance of sea sponges, the Aphrocallistes beatrix that we have been seeing, has been found to produce a compound called aphrocallistin which inhibits the growth of a panel of human tumor and most impressively shown to induce G1 cell cycle arrest in a pancreatic carcinoma cell line. Hopefully it might be developed into a treatment for the very difficult to treat pancreatic cancer. [17:11:53] amybowman leaves the room [17:13:04] carolynruppel leaves the room [17:13:33] adamskarke leaves the room [17:13:46] Similar bamboo coral whip to that imaged earlier [17:14:03] Dense polyps, all sides... [17:15:19] carolynruppel leaves the room [17:15:31] fish [17:16:00] carolynruppel leaves the room [17:16:17] I nust hope we can develop a way to synthesize the natural products and so not need to harvest these slow-growing deep-sea animals. [17:16:24] *nust = just [17:17:09] Or stick the genes into bacteria to grow them. [17:17:41] Well said Adam. [17:17:47] @Scott That is a very important subfield indeed. I worked on a project where we attempted to isolate the microbes from a sponge that produce the medicinal compounds originally isolated from the sponge. Then we would do exactly that. Find the genes responsible and stick them in E. coli or S. cereviseae [17:18:39] Hello all [17:18:47] hi Asako [17:18:50] That field is called Natural Products Biosynthesis. It combines microbiology, molecular biology, genomics, and chemistry as well. [17:18:56] Outstanding Nolan. I know from a commercial perspective it would not be viable to depend on fresh collections of the sponges, etc, for providing medicines. [17:19:00] Hi Tina [17:19:02] @Asako Hello! How are you today [17:20:17] looks like more eggs [17:21:43] Hi Nolan! I just wake up :) [17:21:48] octopus nursery! [17:21:58] @Scott Yes, its very expensive. There are a lot of Organic Chemistry labs (Academic and Industrial) that solely focus on natural product chemical synthesis. Often times, while in the process of trying to synthesize these important molecules, they discover novel mechanisms and reactions that then go on to become very important. Some even are Nobel Prize important. [17:22:15] @Asako I love waking up to Okeanos! [17:22:57] While chemical synthesis is important, it is also quite expensive. So there's a huge shift towards biosynthesis. [17:23:05] @nolan, I do not know if Asako likes it, it is 2.22 am in Tokyo [17:23:54] An extremely successful biosynthesis example is the commercial production of insulin. [17:25:05] @Tina and @Asako That's right....I forget about different time zones... So thank you both for sacrificing sleep to be with us! [17:25:15] @Nolan: I'm trying..... @Tina: thank you! I can't do as you did. [17:26:04] fish [17:27:05] stevenauscavitch leaves the room [17:27:55] @nolan, NO THIS TIME!!! I am sarcificing dinner and dogwalking, it is 20.30 here [17:28:58] Bathypterois grallator [17:29:04] @Tina: no Tina! your DOG sacrificing walking! [17:29:10] Maybe Asako has just come in after a night of wild partying... [17:30:00] @Tina Oh goodness! Make sure to keep your dog happy! [17:30:03] kelleyelliott leaves the room [17:30:19] @scott, yes, I forgot about parting that I am sacrificing as well)) [17:31:03] @Scott: I may have weeks of wild partying... [17:31:41] munnopsid isopod [17:33:56] @Tina and @Asako Party animals! [17:34:52] and another tube anemone, can we zoom? [17:35:07] @Nolan, @Tina: Deep sea party!:) [17:35:44] @Asako The best kind of party! I think my party animal would be a squid! [17:36:19] have to leave for half of hour [17:37:05] @nolan, party animal is sponge with anemones,,, and Antipathes dendrochristos) [17:37:23] tinamolodtsova leaves the room [17:38:23] see you Tina! [17:39:43] check crinoid just left [17:39:55] scottfrance leaves the room [17:39:58] tinamolodtsova leaves the room [17:40:24] sorry.. right [17:40:27] tinamolodtsova leaves the room [17:41:35] is the crinoid Monachocrinus? [17:41:44] If possible, try to snip the crinoid below the bryozoan that is growing on the stalk. [17:45:14] enriquesalgado leaves the room [17:45:31] amybowman leaves the room [17:48:51] Interesting how the base just fell right off the rock. [17:49:44] like it was barely attached. I thought these were cemented down firmly. [17:49:56] EX1803 DIVE14 SPEC03 BIO 2284m Stalked Crinoid: Monachocrinus [17:51:11] @Asako Love it! [17:52:16] stevenauscavitch leaves the room [17:52:42] Some stalked crinoids can move around, I believe, using the short cirri that arise from the main stalk. [17:52:55] So not firmly attached in that case. [17:56:47] rachelbassett leaves the room [17:58:33] Is it shedding scales on its side or maybe its damaged? [17:58:39] Cataetyx laticeps? [17:58:51] there was a parasite on one side of the fish [18:00:31] I think maybe pythonaster [18:00:56] Would be interesting to see if its eating a sponge again [18:06:41] platyctenids [18:08:24] I was just going to follow up on what Daniel said. Those platyctenid ctenophores seemed to have a liking for Walteria sponges in the Pacific. [18:08:54] amybowman leaves the room [18:11:53] elizabethurbangedamke leaves the room [18:15:05] Possible Tretopleura? [18:15:13] @adam & @ daniel...while science-grade ROV's typically can't knock off a chunk of rock, Industrial-grade ROV's can due to great power in manips. They can also carry several hundred pounds to surface. So traditional pick hammer geology is possible with the dollars are there. [18:15:23] @Scott That's what he thought the one from yesterday was. [18:15:35] I agree this is likely Tretopleura as well [18:16:29] i'd like to see a pick hammer in a manip :) i've seen a crow bar in action [18:16:50] @robertcarney: Great point. I know a number of industrial ROVs carry rotary drills capable of cutting out rock samples from outcrop. [18:17:51] It's amazing what a 300 horsepower ROV can do...no picking crinoids [18:18:02] Have also seen a submersible with a "chainsaw" attachment collect hydrothermal chimneys. [18:18:21] Nice screensaver image there! [18:20:59] What do others think of a collection of a stoliferan coral? [18:21:07] *stoloniferan [18:21:52] As long as the collection made using the chainsaw:) [18:22:08] *ISN'T [18:22:24] :) [18:23:20] Maybe collect the branch on the left that has sponge, bryozoans, and stoloniferans? [18:23:37] good idea :) [18:23:59] @Nolan: I thought same thing, but I can't tell if that is a single slender branch or something larger attached to the rock, e.g. old holdfast [18:25:04] @Scott As you said that, I was thinking the same thing. I didn't get a good enough view of the "rock" behind it to distinguish it from whatever the sponge/byro/stoloniferans were on. [18:25:29] tinamolodtsova leaves the room [18:26:38] kelleyelliott leaves the room [18:27:03] That branch is smaller than I thought when zoomed in! [18:27:18] @Scott I thought the same thing! [18:27:52] I suspect this skeleton will be very brittle... [18:28:22] Or not! [18:30:20] Hi all, just managed to join! And at the right time, beautiful sponges [18:31:32] Both the small upright and the large ruffly one are glass sponges. The smaller one looks very much like Farrea herdendorfi [18:32:14] the larger one could be a new species of Farrea [18:32:27] @Joana I'll have more screen grabs for you tonight, if you'd like [18:33:03] if there's an opportunity to collect a piece of the large one that would be excellent [18:33:30] @nolan excellent, thanks! [18:33:43] I just saw the e-mail you sent me [18:33:58] today is a holiday in many European countries [18:36:20] adamskarke leaves the room [18:36:20] laurenjackson leaves the room [18:37:46] @Joana Oh haha! You're welcome! Happy Holiday!

[18:46:02] joanaxavier leaves the room [18:47:29] yes, Euplectellidae [18:48:31] adamskarke leaves the room [18:49:12] encrusting sponges are virtually impossible to identify from images alone [18:49:42] adamskarke leaves the room [18:50:04] Another Anthothela? [18:51:26] scottfrance leaves the room [18:51:33] zoanthid [18:51:45] too many tentacles [18:52:31] I feel like I am back on the North Pacific - my internet periodically cuts out! [18:52:43] I agree those were zoanthids [18:53:01] adamskarke leaves the room [18:54:33] joanaxavier leaves the room [18:54:56] adamskarke leaves the room [18:57:02] J-clade is for Jasonisis? [18:58:00] I am beginning to get som clue in bamboo taxonomy..... [18:59:35] @Tina: sort of. On the phylogenetic tree of Keratoisidinae there is a large clade (by large I mean lots of diversity), and so far the only described species in that clade is Jasonisis thresheri. I don't believe these are all that species, but they fit some of the morphologocal characteristics of Jasonisis, including thick tegument with many scale-like sclerites. [19:01:37] @scott, but tegument is not always present? [19:01:44] adamskarke leaves the room [19:02:11] joanaxavier leaves the room [19:02:13] @Tina: sure. But I use that as a way to say the tissue appears "thicker" in the in situ imagery. [19:04:07] robertcarney leaves the room: Replaced by new connection [19:04:18] yes, definitely Hyalonema [19:04:30] difficult to say which species, there are three reported for the area [19:05:00] adamskarke leaves the room [19:05:13] H. kenti, H. schmidti, H. toxeres [19:06:16] carolynruppel leaves the room [19:07:12] tinamolodtsova leaves the room [19:07:40] zachproux leaves the room [19:07:53] Based on the shallow ater Mediterranean species, Corallium rubrum.

[19:18:28] J-cade&) [19:19:58] adamskarke leaves the room [19:20:35] Keratoisidinae [19:20:54] Needles in view. Not to long. [19:21:09] joanaxavier leaves the room [19:21:31] C or D or B clade... [19:21:47] I am bamboozled - again. [19:22:05] no spindels in body, inly intertentacular spines [19:22:19] That is what I thought, Tina [19:23:46] Farrea sp. [19:23:53] adamskarke leaves the room [19:25:52] joanaxavier leaves the room [19:26:27] sampling? [19:27:59] is there interest to sample? [19:28:19] amybowman leaves the room [19:28:36] Sorry - I was looking at December's sampling... [19:28:51] Don't see one like this sampled but should check on Bahamas samples. [19:29:48] i thonk sampling will be good even if there is Bahama sample [19:29:55] This looks a lot like something we collected in Little Abaco Canyon, Bahamas, we called kerI2c... [19:30:06] from 1600 m [19:31:23] I would call it Isidella kerI2c for the database [19:32:24] Thanks Scott [19:34:08] I should note that the ID of kerI2c is a best guess based on the most similar looking colony level image, that being the one I referenced above from Little Abaco Canyon. [19:34:42] But Isidella is a good identifier because this branches at the nodes and is planar - a couple of classic Isidiella characteristics [19:35:08] [if there is such a thing as Isidella... Taxonomy judges are still out on that one.] [19:35:14] adamskarke leaves the room [19:37:15] Chuck Fisher and Erik Cordes collected an Isidella KerI2 type (but NOT I2c) from Green Canyon at 1400 m depth. But it was a deep red-orange color - the entire colony! [19:37:19] adamskarke leaves the room [19:37:34] I mean the entire colony was deep red-orange in color. Quite dramatic. [19:38:09] @nolan I'll have to leave now but I'll follow up with you on the IDs of the screenshots you've sent (+ made in this dive) [19:39:50] adamskarke leaves the room [19:39:50] laurenjackson leaves the room [19:40:06] joanaxavier leaves the room [19:42:11] loging out [19:42:14] robertcarney leaves the room [19:44:38] erikcordes leaves the room [19:46:35] scottfrance leaves the room [19:48:05] adamskarke leaves the room [19:49:01] EX1803 DIVE14 SPEC04 BIO 2276 m [19:49:32] Geta sample. Am looking forward to determining if that is the same as the species collected on the other side of the Florida Peninsula in Little Abaco Canyon. I wonder how much greater its distribution will turn out to be? [19:49:44] *"Geta" = Great [19:55:03] Bamboolicious [19:56:17] michaelvecchione leaves the room [20:00:03] planning call 330 CT [20:00:35] Copy that. [20:02:21] mikeford leaves the room [20:02:45] Scott, I think Dive 03 from EX1705 had the best example of a h-d coral forest [20:03:01] Thx Amy [20:06:57] adamskarke leaves the room [20:08:07] adamskarke leaves the room [20:08:54] Remarkable... check out thius image from the other side of the world and note the similarities: https://oceanexplorer.noaa.gov/okeanos/explorations/ex1705/dailyupdates/media/may2-3.html [20:09:33] Not necessarily the same species, but they are also large planar Isidella [20:10:18] it was something similar one of last dives at musicians [20:10:42] no anthomastus this dive?? [20:11:04] no [20:11:13] Would have been even more spectacular a place to START the dive! :-) Why do we always find these at the end? [20:11:17] laurenjackson leaves the room [20:11:28] interesting [20:11:37] I know - because we are near the top... [20:13:34] Did we collect anything with bryozoans? [20:13:54] Very large Hylonematid [20:15:01] @megan We tried to do a multiorganism collection, but the branch of dead coral that had a sponge, bryozoans, and stoloniferans was more difficult to grab then a different branch. [20:15:09] Looks like a new sponge. [20:15:21] Or a larger Hyalonemid [20:16:16] @nolan Ah, got it. Thanks for trying! maybe there will be some accidental ones somewhere.
