This is Jim Neilan, NASA Langley - Autonomous Systems Development [13:05:24] Thank you for joining us @jamesneilan [13:07:08] Tuning in before my 9:00 meeting. [13:09:24] Are you seeing anything on sonar? [13:17:23] Hi Jim! [13:17:57] @Jim - joining via the chat works well too! [13:18:06] Hi Jack! thanks for joining [13:18:37] Thank you, excited to learn and see more! [13:23:52] hey Jack, nothing visible on the sonar yet [13:32:48] adriennecopeland leaves the room [13:34:22] taraluke leaves the room [13:37:55] If you find the wreck and it is potentially leaking oil- would there be any consideration to contain it? [13:42:15] Is there an ETA on arrival to the site? I may have missed it earlier. Thanks [13:43:54] could we zoom in on one of the thicker white corals. It looks like they could be scleractinia or possibly stylasterid [13:49:59] about 130 meters from expected target [13:50:03] @johnreed - The Coast Guard has a program to monitor and contain oil leaking from shipwrecks. [13:50:58] could we zoom in on one of the thicker white corals. It looks like they could be scleractinia or possibly stylasterid [13:51:30] @rachelbassett I think there is a push to get to the target. From my relatively untrained eye and a sample that was collected yesterday, I would agree that the thicker white corals is a stylasterid. [13:51:44] Gotcha. Thanks! [13:59:36] taraluke leaves the room [14:03:50] robertcarney leaves the room [14:12:56] Beryx fish- Alphonso [14:13:15] we are on the edge of the target site [14:14:29] crab! [14:23:29] Alexis Weinnig leaves the room [14:23:43] johnreed leaves the room [14:27:46] michaelvecchione leaves the room [14:29:58] I sat in on almost the entire dive yesterday....at the end of the day I was exhausted from the high state of observation is took just to watch! Im very impressed at your professionalism, skills and quality of the products ya'll make. Your team is awesome! [14:30:11] I am not a fish guy- but the grey ones may be barrel fish, They are not wreck fish. [14:30:40] oh okay thank you @johnreed [14:31:00] the big guy? [14:31:57] The ones swimming- not the one under the rock [14:32:51] gotcha - thanks! [14:32:58] @kelleybrumley thank you so much! We have a great team to work with out here! [14:33:45] This habitat and species are very similar to what we described on Pourtales Terrace off Florida Keys. [14:34:14] sqat lobster attacking a fish. lol [14:35:05] a sample of the outcrop might be interesting. [14:35:08] If you get a chance to sample a rock ledge like this today that would be great [14:36:25] Some of the stalked white fan sponges are Phakellia [14:36:53] Looks like more ferromanganese oxide crust [14:37:30] Yes, we cannot sample until we have officially declared this not an UCH dive. But it is at the top of the sampling list once we are able to sample [14:37:51] The rock that we sampled yesterday was dark all the way through, too [14:37:53] And most of the corals are Stylaster- same as on Pourtales Terrace- Phakellia and Stylaster, rather than Lophelia dominated [14:38:00] Yes, UCH is priority. Thanks! [14:38:54] yeah agreed @johnreed [14:39:21] @amywagner- that is surprising. In the GOM it was a thin coating (less than mm) on light tan limestone [14:41:32] Mesh fan sponge- Raspailliidae [14:46:20] @adamskarke I was really surprised. We don't have any HCl to test whether it is carbonate based. [14:48:26] kevinkocot leaves the room [14:49:43] Not seeing any of the Nav data- depth temp [14:52:33] @amywagener - in a pinch white vinegar or even apple cider vinegar (maybe check with the galley) can work but the reaction is not as vigorous. If you powder the rock sample a bit with a file it helps. [14:52:45] While we are still at a potential UCH site that is currently not being displayed but we should be able to get it back up and running [14:53:33] we are going to work to the north east side of the feature before making a call on the UCH designation [14:53:46] Small Lophelia pertusa [14:54:54] taraluke leaves the room [15:03:31] do you know why these thick ferromanganese crusts grow here and not other places? I dredged soooo much of it in the Arctic but I never could figure out why it was some places and not others. Here I fiugre its a current thing and the sediment input isnt enough to support the mounding corals so these crusts can grow?? [15:05:00] We have studied two areas in Straits of Florida where all the surficial rocks are covered with black manganese crusts- [15:05:37] Pourtales Terrace off Florida Keys, and Miami Terrace off Miami- ft Lauderdale [15:05:45] It is very common on the Florida escapement [15:09:10] yeah, I just wondered after watching all the dives the past few days,it seems to be thicker here than elsewhere [15:12:39] Fish apartments. Too cool! [15:16:02] colleenpeters leaves the room [15:17:24] heatherjudkins leaves the room [15:17:29] hes pretty cute. [15:17:32] lauraanthony leaves the room [15:19:29] michaelbrennan leaves the room [15:19:51] heatherjudkins leaves the room [15:21:20] so look at that big sheet of Mn crust that broke off! So seems to have created that one layer, it breaks, and provides the ledges. [15:21:50] Hello all [15:22:33] Deepwater portunid. Those arm spines should be diagnostic [15:23:12] @kelleybrumley it may be more visible here since there isn't as much coral rubble and sediment accumulation [15:23:32] We will certainly get a sample now that we re officially a benthic dive [15:23:52] Hi All @15:20 UTC we officially have called this dive as NOT UCH and will proceed with a normal benthic dive. [15:24:18] @kelleybrumley - The formation mechanisms for Fe-Mn crust are not well understood but interestingly most estimates indicate accumulation rates of 1-10 mm / million years [15:25:35] Thick deposits indicate very long exposure to seawater [15:27:10] http://nora.nerc.ac.uk/id/eprint/523171/1/1-s2.0-S0009254119301019-main.pdf [15:28:40] There are many species of Stylaster here.. We found over a dozen at Pourtales Terrace- Stephen Cairns, Smithsonian curator, is the expert on these. [15:29:45] @johnreed we collected one yesterday with one of our other samples but may try to grab another here. [15:35:00] Alexis Weinnig leaves the room [15:43:53] rachelgulbraa leaves the room [15:44:13] The portunids are bBathynectes longispina, the athyal swimming crab [15:44:17] dying of cuteness! [15:44:21] Bathynectes longispina [15:45:03] reduced swimming legs and enlarged walking legs compared to other portunids [15:45:28] Large male mate guarding a female. . . [15:47:02] the males will often guard the female until she molts which is when they can copulate [15:49:12] Question for the ROV team... is the nav data shut off due to the UCH site? [15:50:07] can we turn it back on? [15:52:16] @colleenpeters ah, yes, thank you for pointing that out! We are working on getting it back on. [15:52:30] awesome, thank you! [15:52:36] lauraanthony leaves the room [15:56:43] Hi everyone, just taking a very quick peek between meetings and WOW, that's one of the densest (and most diverse) sponge gardens I've seen. Truly spectacular! [15:57:52] colleenpeters leaves the room [15:57:58] Several species of tetractinellis, axinellids, poecilosclerids (I could go on an on) [15:58:02] @Joana Hello! [15:58:32] @Joana Was going to start sending you screen shots to ask for some ID advice! [15:58:38] I agree @joanaxavier! I'm speechless [15:59:05] @nolanbarrett, Hi, please do send by e-mail [15:59:26] Hi Cris, great that you're joining too! [15:59:39] @Joana Will do! I'll also send them to Shirley Pomponi as well. [16:00:23] LAT : 31.595108 , LON : -79.102265 , DEPTH : 447.8493 m, TEMP : 10.63108 C, SAL : 35.31469 PSU, DO : 4.05451 mg/l [16:00:29] That reticulate sponge again! [16:00:38] Was that collected before? [16:00:50] thanks ROV team [16:00:53] no not collected so far [16:01:12] @Allen Hello! [16:01:31] Hello! [16:01:34] If you have any chance of collecting 1 specimen of the most common species that would be brilliant, it would allow us to fully characterise this type of habitat [16:02:17] Lovely Geodia on the bottom left of the image :-) [16:02:22] @Joana Which would you prefer? [16:02:56] @Joana This expedition, we have collected Aphrocallistes beatrix, Vazella pourtulesii [16:03:35] @nolanbarrett, that's brilliant, we can possibly still add those to our ongoing genomic work [16:03:59] allencollins leaves the room [16:05:16] @Joana Yep! These are the ASPIRE list. We have not collected Geodia yet. Not seen any pheronema [16:05:23] LAT : 31.594993 , LON : -79.10235 , DEPTH : 446.2003 m, TEMP : 10.63456 C, SAL : 35.31471 PSU, DO : 4.05443 mg/l [16:05:40] @nolanbarrett, really hard to choose... I'd say one of the fan-shaped ones and perhaps a Geodia [16:07:21] @Joana The full fans of the white fans with large fenestrations? [16:07:59] this is painful... I wish I could skip my next meeting... [16:08:07] gotta run in 3 min [16:08:13] we wish you could too!!! [16:08:25] the one on the screen now looks very interesting [16:08:52] @Joana I'll keep collecting screenshots for ya! [16:09:03] not sure what it is but it could be a "rock sponge", a lithistid tetractinellid [16:09:19] lovely Geodia cf. megastrella [16:09:29] @Joana We have not seen that many lithistids today. [16:09:30] kelleybrumley leaves the room [16:09:40] if you find a smaller one and have the chance to collect that would be brilliant [16:09:52] okay noted @joanaxavier [16:09:58] colleenpeters leaves the room [16:09:59] @Joana A smaller lithistid or Geodia? [16:10:09] a smaller Geodia [16:10:24] LAT : 31.594945 , LON : -79.102387 , DEPTH : 447.3813 m, TEMP : 10.63242 C, SAL : 35.31493 PSU, DO : 4.05154 mg/l [16:10:29] @Joana Gotcha! We will be on the look out! [16:12:13] @Alexis, that is very true, sponges are actually "feeding" all of this diversity, by transforming dissolved organic carbon into particulate carbon that can then be used by higher trophic levels [16:12:17] allencollins leaves the room [16:12:22] this is known as the "sponge loop" [16:12:39] ohh great note joana, thank you! [16:12:51] I will relay that on audio soon [16:13:06] and was found by some Dutch colleagues from the Univ. of Amsterdam some years back (in shallow tropical reefs) [16:13:37] have a look here: https://science.sciencemag.org/content/342/6154/108 [16:13:47] gotta go, already late for my meeting [16:13:53] will be back as soon as possible [16:13:57] Thanks Joana! [16:15:03] joanaxavier leaves the room [16:15:24] LAT : 31.594886 , LON : -79.102541 , DEPTH : 444.2029 m, TEMP : 10.63639 C, SAL : 35.31522 PSU, DO : 4.05909 mg/l [16:15:38] taraluke leaves the room [16:16:53] @WatchLeads Would it be a possibility to collect a geodia as an ASPIRE collection and one of the fans (something in the Axinellidae family, I think) as a representative of the habitat? One or the other? What are your thoughts? [16:17:30] allencollins leaves the room [16:17:35] We will probably be able to collect one sponge today [16:18:40] We would love to have one of the small white gorgonians if possible [16:19:03] Good opportunity to gte a look at the snail on the upper right of asteroid... [16:19:20] I was too slow - my bad. [16:19:26] @Alexis Gotcha okay. [16:19:58] So many sponges - will be hard to choose the one that is "representative"! [16:20:25] LAT : 31.594793 , LON : -79.102514 , DEPTH : 445.163 m, TEMP : 10.64846 C, SAL : 35.31699 PSU, DO : 4.05932 mg/l [16:20:48] After this sponge, can we look to lower right (you'll have to pull out) - something orangey-brown in color. [16:20:56] @scottfrance true - we have had some requests for a geodia [16:21:29] Ophidiaster [16:23:22] What are all the finger-like "tubes" that were poitning down on that overhang? Worm tubes? Molluscs? Coral? [16:23:36] ll the brown-ish ones? [16:24:04] They looked whitish with a change in color along the length, suggesting a tube with something retracted. [16:24:24] Oh okay we will keep an eye out [16:25:13] @Alexis any chance we can collect one of the small white gorgonians? [16:25:25] LAT : 31.594755 , LON : -79.102595 , DEPTH : 443.539 m, TEMP : 10.64613 C, SAL : 35.31649 PSU, DO : 4.05331 mg/l [16:26:04] allencollins leaves the room [16:26:39] @rachelbassett possible - we have collected 3 of them on the cruise so far [16:27:09] oh great! thanks. [16:27:15] Ooo Lithistid sponge aka Rock sponge! [16:28:16] The gastropod on the other sponge looks like a Calliostoma [16:28:55] Here are more of the tubes I was referring to earlier (right of sponge)... [16:29:18] ...they are kinda transparent looking with a pinkish blob partway down. Hydroids? [16:29:26] I think so, Scott. [16:29:39] @nolanbarrett are all of those small, "fluffy" looking balls geoidia? [16:29:42] Interesting they all appear retracted. [16:29:46] I think they could be a type of stoloniferan too… [16:29:54] allencollins leaves the room [16:30:26] LAT : 31.594732 , LON : -79.102572 , DEPTH : 445.8561 m, TEMP : 10.66117 C, SAL : 35.31818 PSU, DO : 4.0609 mg/l [16:30:31] @Alexis: could be, though each "tube" is pretty tall. [16:30:37] Yeah, all of them have been closed so far [16:30:46] It has spiny projections so I don't think Ophidiaster. [16:31:01] @Alexis: that is, a bit different from the "typical" stoloniferan I'm used to seeing. (Is there such a thing?) [16:31:12] Maybe Solasteridae? [16:32:40] Family is: Korethrasteridae [16:34:47] allencollins leaves the room [16:35:26] LAT : 31.594672 , LON : -79.102599 , DEPTH : 445.6882 m, TEMP : 10.6638 C, SAL : 35.3192 PSU, DO : 4.04477 mg/l [16:37:00] allencollins leaves the room [16:37:54] Portunid crab [16:37:57] The spherical geodia at bottom of screen- may be Geodia megastrella, Paco Cardenas id [16:39:09] allencollins leaves the room [16:39:15] @John When Joana Xavier was on, that was her ID also [16:40:27] LAT : 31.594623 , LON : -79.102625 , DEPTH : 444.9626 m, TEMP : 10.66927 C, SAL : 35.3194 PSU, DO : 4.05076 mg/l [16:44:08] Solasteridae [16:44:14] Luidia ciliaris? [16:44:53] Often shallow but also down to 400m or so [16:45:27] LAT : 31.594602 , LON : -79.102637 , DEPTH : 445.9306 m, TEMP : 10.66797 C, SAL : 35.31882 PSU, DO : 4.03078 mg/l [16:45:53] nevermond! [16:47:40] We've been seeing a lot of unusual stuff today! So cool! Stump the expert day! [16:48:26] Reticulate stuff is likely stoloniferous octocoral. [16:49:17] Another of those finger-like stalks with pink just behind the asteroid. I wonder if they are tunicates. [16:49:57] @Scott do you mean stoloniferous on rock? [16:50:18] @Asako: earlier, yes. Chris refered to the reticulate mat. [16:50:27] jamesneilan leaves the room [16:50:28] LAT : 31.594604 , LON : -79.102624 , DEPTH : 445.4657 m, TEMP : 10.67458 C, SAL : 35.31919 PSU, DO : 4.03264 mg/l [16:51:28] @Scott OK thanks. you mentioned it before as well? I missed to see it. closed my eyes, just heard :) [16:52:05] williamclancey leaves the room [16:52:35] iscwatch2 leaves the room [16:55:28] LAT : 31.594587 , LON : -79.102667 , DEPTH : 444.595 m, TEMP : 10.67224 C, SAL : 35.31947 PSU, DO : 4.03659 mg/l [16:56:06] Weird how similar this is to the scene yesterday. I'd swear you were replaying the video! [16:56:26] Yesterday they were feeding on Hexactinellid. Now they are feeding on Geodia demosponge! [16:57:32] Here the finger-like tubes are growing on spines of the urchin... [16:57:57] They look like star-shaped raviolis :-) [17:00:15] @Jim I agree! [17:00:29] LAT : 31.594623 , LON : -79.102741 , DEPTH : 445.0876 m, TEMP : 10.67741 C, SAL : 35.31872 PSU, DO : 4.01995 mg/l [17:01:21] @Jim yes! [17:01:34] lauraanthony leaves the room [17:01:34] As a geologist, I love the enthusiasm here. :) [17:03:04] jodontocete awbone?? [17:03:06] @jennahill yes!! :) [17:03:12] odontocete jawbone? [17:03:52] Blackbeard's sword. [17:04:11] Billfish rostrum?

[17:11:11] @Alexis They could be any number of things. They are hard to get details on... [17:12:32] This white fan is Axinellidae, maybe Phakellia sp. or Axinellida [17:12:48] Ill send the screenshots to Joana [17:13:08] @jennahill there was a lot of discussion earlier about them being ferromanganese oxide crust. We've tried several chunks to see if they are loose and no luck so far. [17:13:22] We did collect a similar type rock on the dive yesterday [17:15:30] LAT : 31.594364 , LON : -79.102853 , DEPTH : 446.8087 m, TEMP : 10.64265 C, SAL : 35.31595 PSU, DO : 4.04247 mg/l [17:16:59] scorpeonfish [17:18:55] @amy certainly could be ferromanganese...hard to tell from afar. I have some similar looking rocks from shallower (~~200m) that have a lot of phosphorite (we sliced them open), so that's why I suggested that. [17:19:55] johnreed leaves the room [17:20:19] kelleyelliott leaves the room [17:20:31] LAT : 31.594357 , LON : -79.102945 , DEPTH : 447.4687 m, TEMP : 10.63769 C, SAL : 35.31495 PSU, DO : 4.04689 mg/l [17:22:02] Are the many almost transulcent fan-like colonies here hydroids or black coral? Can we get a look? [17:22:28] You'll see a couple as you pull wide from the crab, or to its upper left. [17:22:45] okay we will ask for a zoom @scottfrance [17:23:04] You'll see they are pretty tallish, kinda l;ike a Bathypathes [17:24:05] Hard to tell if hydroid or antipatharian... [17:24:15] Small Madrepora in sponge to right too [17:24:35] adriennecopeland leaves the room [17:24:38] But I lean to hydroids. [17:24:54] Fairly abundant patch there. [17:24:57] @Scott Me too [17:25:31] LAT : 31.594436 , LON : -79.103021 , DEPTH : 448.0655 m, TEMP : 10.63421 C, SAL : 35.31526 PSU, DO : 4.05503 mg/l [17:26:01] i would agree with hydroids, something obelia like [17:26:33] And a hydroid! [17:26:51] Ort perhaps that is just adjacent to the rock... [17:27:06] I think it is on the rock [17:27:16] Even better! [17:27:50] I am revising this to "pebble" from "rock"! [17:27:54] Embedded pebble!

[17:31:30] I wonder why we have seen a few of the hard corals practically imbedded in these sponges? [17:31:39] Tubes with the splash of pink-orange in them. [17:31:47] jackirion leaves the room [17:33:35] We can sure tell the prevailing current direction here- all the fan sponges perpendicular to the current [17:34:28] Thanks. I think they are stalked tunicates. [17:34:46] My best guess right now, anyway. [17:34:55] @jillbourque I remember seeing those little tubes on the RB1903 cruise, do you? [17:35:01] Was pink thing a sponge? [17:35:20] @Cheryl The one on the yellow coral, I think so. [17:35:21] yeah @CherylMorrison I think the pink was a sponge [17:35:28] That sponge on the zoanthid/coral was interesting and I think was the same morph we saw earlier growing on the edge of a rock. I noted then I ghadn't seen many pink-brown demosponges,.

[17:35:59] @nolanbarrett My guess would be that it is because the current can probably get ripping and the corals may be a bit protected by the sponge [17:36:07] Interesting! Also to see scleracts growing on/in sponges! [17:36:33] shark! [17:36:57] @Amy and @Cheryl That is a very cool idea! I would love to investigate that interaction!

I suspect the coral has grown up around the sponge (the coral provides some architecture for sponge growth) and ultimately will "smother" the coral. [17:45:20] Sorry - I wrote that backwards! I believe the sponge has grown up around the coral.

[17:46:55] I wonder if a chunk had blown off somewhere else and got lodged there. I feel like a sponge larva wouldnt settle on live coral and survive. But maybe on bare skeleton. That might also explain the zoonathids too. [17:48:05] I think the shark was a dogfish (no anal fin).

[18:01:24] the fan one? [18:02:34] @WatchLeads I think Joana preferred a Geodia because of ASPIRE. [18:02:58] We have collected stalked mesh sponges like this- Only could identify as Raspailliidae [18:03:16] So would it be good to have one?

[18:07:20] Hi guys, I think the fan one is better to describe the place [18:07:28] Yes! Collect them all! [18:08:28] I do see where @cristianacastellobranco is coming from [18:08:34] Nicely done. Lars is the rock whisperer. [18:08:37] the fan sponges are everywhere [18:08:52] Its tough becuase Geodia are on the APSIRE list [18:08:54] exactly! [18:09:11] There are also at least 2 types of fan sponges... [18:09:20] I want all the sponges... [18:09:55] Any sponge collection is a good collection!:-D [18:10:16] Sponge is likely stiff, but not brittle.

[18:16:59] Very neat site- There are probably 5-6 spp. of fan sponges.
