[04:21:28] adamskarke leaves the room [11:53:02] robertcarney leaves the room [12:28:50] EX1803_DIVE10 ROV powered off [12:42:12] Predive Test [13:18:44] chat-admin leaves the room [13:19:14] The Okeanos Explorer is on site for Dive 11. Dive will commence shortly. Pre-dive call at 8:30 CDT. [13:23:16] EX1803_DIVE11 ROV Launch [13:30:08] EX1803_DIVE11 ROV on Surface [13:30:24] Hi all, I'll be annotating geology every 1 minute for today's dive. [13:30:59] pre-dive call at 8:30 CT [13:31:12] EX1803_DIVE11 ROV Descending [13:42:08] tinamolodtsova leaves the room [13:50:08] nolanbarrett leaves the room [13:55:25] paullarson leaves the room [13:57:10] adamskarke leaves the room [14:06:33] adamskarke leaves the room [14:12:24] EX1803_DIVE11 ROV on Bottom [14:18:15] Hollardia [14:25:19] Aphrocallistes beatrix [14:26:14] Brachiopods on that little rock with the encrusting sponge? [14:28:45] Small hatchetfishes above the bottom. [14:28:57] possibly Muriceides? [14:29:53] Mysid shrimp swimming next to the octocoral. [14:30:30] Dr. Etnoyer isn't in the chat room, but he wanted me to mention that he's annotating sessile fauna and not focusing on crabs and fishes [14:32:11] Actually not hatchetfish, but not sure what. [14:32:52] agree chuck. Looked like a juvenile Hollardia sp. [14:34:04] @daniel - that's a new one for me. [14:34:30] Bamboo whip sp. I don't know what this is but I've seen it throughout the Greater and Lesser Antilles at these depths <600m. [14:35:23] Can we zoom on smalll urchin to right of antipatherian [14:36:05] copy that zach. We need to get close ups for our video team [14:38:05] The urchin looked unusual as it had no spines on the aboral surface [14:44:18] look righ tthere [14:44:37] on sediment, it was carbonate colored [14:45:31] Sorry, it was that first black coral [14:45:41] Not priority [14:45:51] I'll keep my eyes peeled for it, thank you [14:45:57] thanks nolan [14:50:45] The brown bushy little tree in front is an agglutinating foraminiferan, probably Astrorhizacea. [14:52:22] Urchin to right of this zoom [14:52:50] That's him! [14:53:10] Thank you! [14:55:28] Let's not ignore the fishes. Corals are cool but so are the fishes. [14:56:13] Trichiurdae I think for that one in a vertical orientation. [14:56:29] Are those small white sparsely branched octocorals plexaurids? Perhaps Eunicella? [14:57:10] Trachichthyidae for the larger one ? [14:57:38] Red Anthomastus soft coral - have I got that genus right? Or Pseudanthomastus? [15:00:59] @chuck, I need macro to get genus usually) [15:01:42] Fishes encountered so far: 'coral hake' = Laemonema goodebeanorum; reddish angler = Chaunax suttkusi; silver-grey beryciformid typically drifting with body angled = Hoplostethus occidentalis (not Gepyyroberyx darwini, which is reddish and swims horizontally) [15:03:35] You can also see in that zoom on the stylasterid the small "prong" or style in the middle of the cups (calices) that give stylasterids their name. [15:06:46] kensulak leaves the room [15:09:17] adamskarke leaves the room [15:09:50] I'm seeing some small primnoid fans in the area too. did we image them earlier? [15:10:05] acanthogorgia [15:10:20] agreed [15:12:36] @Steven I don't think we have zoomed on those fans. We have seen some bryozoan fans which we imaged, but not primnoid fans [15:14:08] Active defense of coral by squat lobster against a Hoplostethus [15:18:36] markbenfield leaves the room [15:22:19] scaber? [15:22:24] Polychaete might be tomopteris [15:22:37] @Tina Cutlass fish [15:22:48] Trichiurdae [15:23:10] @Tina there are so many fish named after different types of swords and blades [15:23:23] it is not Leipathes that colony left [15:23:40] can we zoom? at purple one? [15:24:19] Crinoid or asteroid? [15:26:13] was something living in/on the calyx? [15:28:09] this may be Alternatipathes... or something close to bathypates platicaulus [15:28:25] actually I asked about another colony [15:28:42] thanks first zoom looked like something was there mobving around [15:28:55] thanks tina. I know that in your paper with dennis you were referring to the gulf of mexico species as bathypathes [15:29:07] Very large leiopathes to the left [15:30:39] daniel, no... it is just about material I have seen from Smithsonian [15:32:11] lasers, please? [15:32:19] thank you [15:32:28] covered with hydroids [15:33:59] I have to be in and out. Among the dead Lophelia, can you please keep an eye out for small yellow feather stars - perhaps with an arm spread of at most ~~60mm. It would be Comatilia - a brooder so far found only among dead Lophelia on the Florida-Georgia east coast. Sometimes in huge numbers. [15:35:57] Thanks for spotting that Dan. Those are the "primnoids" fans I was referring to earlier. [15:36:30] plumarella [15:36:51] Also would be interesting to zoom in on the dead Lophelia rubble to see what small organisms are growing on it. On the east coast, the dead branches are often covered with a turf of branching agglutinating foraminiferans, accompanied by barnacles and hydroids. [15:37:30] Interesting how they are more common on rubble as opposed to the outcrops here. [15:38:42] 100 m transit complete [15:47:24] paullarson leaves the room [15:47:52] zoom in on those fish please [15:48:06] fish zoom [15:48:21] Eumunida on coral. [15:48:55] what kind of fish these are??? [15:49:42] Argentina striata [15:50:11] they usually behave like this? [15:52:52] stevenauscavitch leaves the room [15:55:54] Argentina striata is commercial fish? [16:02:55] paullarson leaves the room [16:04:10] adamskarke leaves the room [16:05:04] What is the name of this coral please? [16:05:28] Acanthogorgia [16:06:39] Hello all [16:06:54] hi Asako [16:07:07] Hi Tina! [16:07:13] Hi Daniel! [16:07:26] @Asako Hello! [16:08:09] Hi Nolan! [16:15:36] There are a few little brown tree-like agglutinating forams on the dead coral branches around that white sponge. [16:17:20] echinus [16:17:57] I think now Gracilechinus, unless it's been changed back again. [16:20:20] thomasritter leaves the room [16:23:33] @charles, it is back my guess.. [16:23:57] goniasterid? [16:24:25] @tina - thanks. [16:24:40] Go east, young man! [16:25:12] stevenauscavitch leaves the room [16:25:35] It looks too large for Comatilia. Please zoom in on base of arms if possible. [16:27:09] stolonifera? [16:27:37] Excellent shot. Comatonia cristata, I think. [16:28:21] less black corals here... [16:29:19] full of corals. one of the best shots of this cruise :) [16:31:59] @Asako I absolutely agree!!! [16:33:46] @Nolan: yes, wonderful! [16:37:24] nolanbarrett leaves the room [16:38:01] adamskarke leaves the room [16:39:04] paullarson leaves the room [16:40:30] Nephtheidae my guess [16:40:46] and squadlobster [16:41:50] agree its Acanthogorgiid [16:44:49] Epigonus [16:49:48] I don't recall ever seeing those soft corals on Lophelia mounds on the east coast of Florida. [16:53:41] laurenjackson leaves the room [16:54:09] white is crinoid or seastar? [16:58:01] Echinothuridae? [16:58:56] @Tina I think so, according to animal guide [16:59:26] crab [17:00:26] I have to do ome work in the lab, but I'll check the chat periodically. Good luck with the benthic and midwater portions of the dive! [17:00:51] see you Nolan! [17:02:40] Family Atelecrinidae - we have several local species in two genera. [17:03:44] Abundant "tree" foraminiferans around the shrimp. [17:05:35] Atelecrinids have 10 arms that end in a slender filament, long delicate cirri (anchoring "hooks"), and lack pinnules (side branches) on the bases of the arms. [17:05:44] what is the white octocoral colony? is this already id? [17:05:57] at least it looks like Plexauridae [17:06:23] Merluccius albidus [17:09:01] Galeus antillensis [17:10:04] nolanbarrett leaves the room: Replaced by new connection [17:10:34] octopus [17:10:38] thomasritter leaves the room [17:10:44] to the lower right [17:12:03] We are currently ~~150 m east of mounds [17:14:32] beautiful salp [17:15:07] tunicate [17:15:21] A salp. [17:15:25] iscwatch2 leaves the room [17:18:18] covered another 100m transit [17:19:27] paullarson leaves the room [17:23:34] Centrodraco [17:26:54] HI all, sorry but I have to get going. Please get zooms of any sea anemones riding on gastropods. Esp. Xenophorids, if encountered. [17:27:13] paullarson leaves the room [17:27:17] will do. Thanks Paul. [17:27:36] thanks daniel [17:27:47] looks like 2 of worms [17:28:06] trigla& [17:28:15] Peristedion [17:33:26] daniel, can we zoom at one of anthomastus here? [17:33:43] nolanbarrett leaves the room [17:33:55] will do tina [17:34:59] this may be not glaberimma [17:35:06] Heteropolypus now instead of Anthomastus. [17:36:12] @george, nope. it is only about ritterii [17:36:50] may be anthomastus [17:37:17] @tinamolodtsova ahh, my mistake. We mostly have H. ritterii here on the west coast. I prefer Anthomastus [17:37:35] nope. Pseudoanthomastus [17:38:04] @george, you have pseudoanthomastus as well. [17:40:34] @tinamolodtsova, thank you. I'm going to have to brush up on my benthic taxonomy! [17:41:37] Bembrops [17:44:14] Synagrops bellus [17:45:12] Hi [17:45:26] Hello Tracey [17:45:44] Great, sorry to miss them, but look forward to it later... [17:47:47] Coelorinchus? [17:48:00] 100 m transit complete [17:49:48] Have to leave for a while. I'll pass the NSU ball to Tracey. [17:49:55] charlesmessing leaves the room [17:52:45] seapen? [17:54:17] adamskarke leaves the room [17:54:43] are we going to have another mound? [17:56:53] Michelobus lightus, I believe on that debris... [17:57:43] I just joked on Twitter that we had combined Octopus Friday with Shark Saturday today! [17:59:16] идфсл сщкфд [17:59:26] black coral it was [17:59:46] Bathypathus-like [18:07:16] 100 m tranist complte [18:08:29] Anthomastus [18:10:44] hatchetfish, Polyipnus clarus [18:11:18] another urchin [18:13:17] Nezumia? [18:13:26] adamskarke leaves the room [18:13:51] I think so, too. We should be able to do better later. [18:14:51] lasers? [18:16:12] have to go. will try to join youi in 1 hour. [18:16:34] see you Tina! [18:16:48] thanks tina [18:17:35] tinamolodtsova leaves the room [18:20:27] another Polyipnus hovering off bottom... [18:20:57] stevenauscavitch leaves the room [18:24:39] Epigonus [18:25:47] yes, beautiful. I'm lagging the call in by about 60 seconds. [18:26:17] sorry, video lags your voice by 60 sec [18:26:36] not sure about that :-) [18:32:23] 100 m transit complete [18:33:02] Just want to say that despite having selected this site for a dive, I did not expect to find Lophelia in the abundances that we have seen so far. Great dive! Thanks again for all your hard work [18:34:34] adamskarke leaves the room [18:34:39] H. occidentalis [18:35:26] nice. [18:35:54] we may get mediterraneous as well... [18:38:53] GeorgeMatsumoto leaves the room [18:40:23] Polyipnus. Has a diamond body shape compared to argyropelecus [18:41:01] nice video last year of anemone eating a Polyipnus. [18:44:22] at least 4 roughy right there... [18:50:25] adamskarke leaves the room [19:02:06] Comatonia tristata [19:04:07] Just back and caught a final glimpse. Looked like Atelecrinidae - long slender cirri. [19:06:01] adamskarke leaves the room [19:08:36] traceysutton leaves the room: Replaced by new connection [19:09:34] adamskarke leaves the room [19:12:25] another 100 m transit complete [19:22:50] acanthogorgia [19:23:00] Dr. Etnoyer is requesting a sample of this coral to the left [19:23:06] if possible [19:24:42] what would you like to call this coral? [19:24:53] adamskarke leaves the room [19:25:08] Paramuricea [19:26:03] Just a 4-6 inch clipping would be perfect [19:30:24] Epigonus [19:30:42] Yes, and the gadiform in back looked like Laemonema [19:31:05] good eye [19:31:14] seen many benthic-pelagic interactions today? [19:31:53] Good morning, Dhugal! [19:32:43] Morning! No sun yet here. 04:30 and my coffee almost brewed! [19:33:00] Looking forward to some nice blue water! [19:34:16] Morning @dhugallindsay nice salp earlier not too much else yet, but looking forward to midwater [19:35:11] salps are better than chaetognaths ;-) [19:35:19] Hi Dhugal - so far lots of pelagics in the BBL, so I bet we are going to see a lot. [19:35:55] lots of Tomopterus [19:36:39] Solmundaegina? [19:36:48] lobate [19:37:53] Tomopteris [19:38:41] at least three Tomopteris on screen at same time! [19:39:11] more like 7 or 8 [19:39:31] Is this likely an aggregation or just a generally abundant population of Tomopteris? [19:39:43] Tomoptornado - the next in the series. [19:40:06] Bravo on the collection! [19:40:18] physonect siphonophore - not Forskalia but not sure what... [19:40:31] Good morning all [19:40:43] Epigonus [19:40:58] Good morning, Don [19:41:03] first time have seen GoM video so can't say about Tomopteris sorry @charlesmessing [19:41:15] G'day and konnichi-wa Don [19:41:36] This is a lot of Tomopterus [19:42:28] Could this be a mating swarm of benthic polychates, e.g. epitokes? [19:43:13] pretty sure they were tomopteris. got some nice close shots just before [19:43:58] I tuned in late, so no good views. [19:44:09] a species with a proper tail. need to ask Karen Osborn for any ID better than that.. [19:44:20] Yessir, but they still may swarm to mate - I did see ovaries in many, which you don't normally see as a solid mass [19:45:09] First time on this dive since I have been tuned in that we have seen these [19:45:21] Wow! Never ever seen so many Tomopteris at one time... [19:45:36] So many at once.... [19:45:45] me either - nothing even close... [19:46:26] physonect siphonophore. 3 inds. not Forskalia but not sure what... [19:46:43] physonect. diff species [19:47:31] lobate [19:48:34] need to zoom in on some of those physonects before we leave bottom [19:48:43] drats.. left to get lunch at the wrong time! [19:49:38] reckon these fish eat Tomopteris? [19:49:49] From my perspective, I think we will be happy with whatever we get. Thanks! [19:50:32] Do we know what depth we will be at approximately for the sstart of the midwater dives? [19:50:49] scottfrance leaves the room [19:50:55] ~~470 m [19:51:43] physonect. rudjakovia-type [19:51:54] Great zooming - thanks! These guys are hard to tell apart even under a microscope! [19:51:58] Midwater team: Does this sound ok due to high sirface currents? 10 m from bottom for 2, 10 minute transects, then one at 400m 2, 10 minute transects) and the same for 300m if the current isn't too strong? [19:52:11] physonect. same species as the 3 before [19:52:21] so we would spend ~~1h at 470 m, 1h at 400 m, and 30 min at 300 m [19:52:30] sounds good to me. the action seems near the bottom... [19:52:43] as Tracey said, happy to see midwater anywhere :-) [19:52:53] Sounds good to me as well... [19:53:01] take our time between 1m altitude and 10m rather than just pop up to 10m altitude if possible [19:53:10] concur [19:53:12] Hi George :-) [19:55:34] Do we know where the DSL is located by chance? [19:56:19] We will check [19:57:03] Can we get lasers at the base of that leiopathes please? [19:57:19] Thank you! [20:01:40] tinamolodtsova leaves the room [20:05:52] I believe that was a scorpionfish o fthe genus Pontinus... [20:06:12] salp [20:06:29] Just looked at the EK60 with mapping team. Not seeing a well defined DSL. Marginally higher backscatter layer around 100-120m [20:06:46] @Adam- thanks! [20:07:13] was that a lobate? [20:07:45] I think so, Dhugal [20:08:31] a lot of action down here near the bottom! [20:09:10] but Tomopteris has disappeared [20:11:00] carbonate rock? [20:11:44] I was hoping that roughy was going to eat that hatchetfish... [20:12:27] Pteropods? [20:12:33] that fish was blind or had nerves of steel [20:13:36] Very cool- MArlin [20:14:23] juvenile swordfish [20:14:29] A lot of midwater activity in camera 2 [20:14:44] @Tracey- I knew I was off! [20:15:16] Good call, George - that's amazing [20:15:46] that sword may follow the ROV - they seem to use it to hunt [20:15:58] Is someone going to be entering in Seascribe for the midwater portions? [20:16:51] not I - sorry. I am laptopping it, so chat and video is all I can handle. Sorry. I'm chat whatever fish I see... [20:17:11] laptopping here as well. sorry [20:19:51] laptop with headphones so as not to wake anyone so not even voice I am sorry... [20:19:56] ive not done seascribe before but let me try logging in [20:22:05] Dr. Etnoyer asked to please keep the rocks separate from the corals. The mud will clog the polyps [20:22:35] adamskarke leaves the room [20:22:47] call this a carbonate rock? [20:24:09] Nice Nanomia in camera 2 [20:24:19] I am sorry for people on board sorting bio from this rock.... [20:24:45] Tomopteriids are back as well [20:27:12] @lauren: Yes - Carbonate Rock [20:27:21] attracted to light? [20:27:52] They are not in front of the ROV, so my guess is not positively phototactic [20:28:48] I take it back, they are showing up on the main camera now as well [20:29:05] If any of the midwater team is available to hop on the teleconference once we start to introduce yourselves, thanks! [20:29:22] Have you guys ever seen this in MB? [20:30:07] This is the thickest aggregation I've seen [20:30:26] zachproux leaves the room [20:31:44] tinamolodtsova leaves the room [20:32:52] Do we have a good zoom-in shot of one of those Tomopteris? [20:33:20] big salp [20:33:32] I think they tried, but they move so fast... everything is "T. carpenteri" to me (the fish guy)... [20:34:00] is that salp Thetys? [20:34:11] need to zoom [20:34:21] nice one! [20:34:30] Cyclosalpa I think? [20:34:56] bioluminescent oragns in dashed lines along sides [20:35:36] physonect [20:36:17] physonect. can we zoom on one of those once we get set up please. [20:37:27] can we turn laser off please? [20:38:15] physonect. same species [20:39:31] ok im in seascribe and will add things as we go [20:39:43] physonect [20:39:44] charlesmessing leaves the room [20:40:00] Thanks, Don! [20:40:59] @ all- once we get started, feel free to provide factoids along the way about your organisms.... [20:41:27] Aegina [20:41:45] pretty, did you ever see any Aegina eating corals today? [20:41:57] maybe a Bathykorus. need good zoom [20:42:11] looked like had 2 stomach pouches per quadrant [20:42:20] 3 i mean [20:42:31] physonect [20:42:44] start_transect [20:42:54] didn't look tall enough but I'm good with that ID [20:43:05] 460m [20:43:20] adamskarke leaves the room [20:43:48] physonect [20:44:19] rhopalonematid trachymedusa [20:44:30] That appears to be a pretty abundant physonect, it would be good to get a closeup of the siphonophore when you have a chance [20:44:41] Bargmannia! [20:44:50] Bargmannia! [20:45:01] that is my timelag. [20:45:11] This is Bargmannia - a physonect siphonophore [20:45:32] Whaaat. It's a physonect siphonophore! [20:45:44] Halicreatid [20:45:48] Sorry, guys!!! [20:46:04] or narco maybe [20:46:16] looks pretty sad [20:46:22] I think narcomedusa. [20:46:46] larvacean [20:47:01] trying to let you know what they are before we get a good shot so IDs a bit iffy... timelag problem.. [20:47:09] Bargmannia [20:47:21] thanks~~~~~~ [20:47:34] 4 gonads. but Trachymedusa? [20:47:49] I didn't recognize that one [20:48:11] adamskarke leaves the room [20:48:28] Halitrephes [20:49:12] "Aeginid"? [20:49:39] Bargmannia [20:50:02] 2 of them. not Bargmannia elongata, maybe amoena [20:50:19] that fish was probably hatchetfish Polyipnus. Thought Sternoptyx at first, but this is pretty shallow. [20:50:33] oik [20:51:07] Cyclothone [20:51:23] the physonects near the seafloor were almost all Bargmannia also [20:52:06] Cyclothone, probably pseudopallida [20:52:14] Bargmannia [20:52:26] krill [20:52:46] Bargmannia [20:52:59] bargmannia siphonophore not salp [20:52:59] markbenfield leaves the room [20:53:19] Praya is the really long one - can be up to 80 meters [20:53:32] Tomopterid [20:53:48] nice! Would be great to get as tight a shot of the "tail" as possible since the order of the zooids along the siphosome is important for species ID [20:54:24] Steve Haddock has found some tomopteriids with yellow biolum! and of course, tomopterids are featured in the new biolum stamps at our USPO! [20:54:57] cool! [20:55:24] Bathykorus. 2ndary tentacles visible [20:55:47] a jelly that eats other jellies. might eat Tomopteris as well [20:55:59] oik [20:56:27] Bargmannia [20:56:53] yes, a zoom on this! [20:57:13] near tip of tail [20:57:33] great! [20:57:59] it is busy fishing [20:58:13] looked pretty successful [20:58:23] reeling the tentacles up and down [20:58:50] Euplokamid cydippid ctenophore "round square" [20:59:37] larvacean [20:59:43] physonects. not Bargmannia. Rudjakovia type? [20:59:53] hatchet was Polyipnus clarus [21:00:06] Tomopterid [21:00:46] Bargmannia [21:01:53] physonect ghost tail? maybe Bargmannia? [21:02:10] yes, "light" Cyclothone (braueri, alba, or pseudopallida) [21:02:20] adamskarke leaves the room [21:02:26] Bargmannia [21:02:46] cydippid [21:02:57] if you see the 4 tentacled narcomedusa again [21:03:54] Forskalia [21:03:58] Forskalia siphonophore [21:04:22] another Polyipnus clarus [21:04:32] similar to but maybe isn't forskalia formosa [21:04:59] mung [21:05:06] drifting snow [21:05:33] Bargmannia [21:06:38] if we see 4 tentacled narcomedusa would like to zoom on umbrella to see if scattered with nematocyst patches or not please [21:06:55] nice copepod [21:07:08] Megacalanus or Brachycalanus [21:07:22] larvacean hous [21:07:36] The hatchetfish was a juvenile Argyropelecus [21:08:32] Solmissus? [21:08:34] Solmaris? [21:09:04] Solmissus [21:09:16] Solmissus [21:09:26] need to see stomach pouches [21:09:59] one of the cryptic Solmissus species currently known as "Solmissus incisa" [21:11:05] yes, Bathykorus [21:11:12] Bathykorus! [21:11:24] closeup on that one [21:11:50] different species to the ones off Japan. looked closer to the Arctic species bouilloni [21:12:06] Bargmannia [21:12:42] 'just' another fish [21:13:18] Beautiful. Good zoom on the side away from you :-) [21:13:26] Bathykorus. great shot [21:13:39] That IS Sternoptyx - far shallower that we usually see them [21:13:58] OK, was since I am lagging... [21:14:19] Bargmannia [21:14:36] Bargmannia [21:14:50] Bathocyroe ctenophore [21:14:58] Bathocyroe lobate ctenophore [21:15:15] non-fosteri? [21:15:24] Sorry I am getting some jellies incorrect..... I need a cheat sheet :) [21:15:25] non-fosteri [21:15:48]
