[10:57:30] <andrewobrien> Pre-DIVE07 test message
[11:29:41] <kaseycantwell> Good morning all - this morning's dive is delayed. When we arrived on station, the current was 4 kts and the winds were 15-20 kts, making it unsafe to deploy the ROV. We have headed east, further offshore to hopefully get out of the influence of the Gulf Stream, or at least to a more manageable situation. We have picked several potential options that are progressively more and more east, with the first on being ~~30 km from our original site. Our plan is to evaluate the closest site and either proceed to launch or continue on to the next option. We should be at the first site just be for 08:00 EDT and will update you once we have more information.

[13:58:18] <kaseycantwell> Hi all. We had no luck at our inshore sites - currents and winds were still too high for ROV operations. We are currently headed further offshore (to a site south of our planned Richardson Hills sites) and should be on station close to noon EDT to assess the conditions. We'll keep you posted when we have additional information.
[14:03:30] <taraluke> Kasey, you said [object Object].  Was that what you were planning to say?

[16:47:33] <okexnav> EX1806_DIVE07 ROV powered off
[16:52:49] <kaseycantwell> We are proceeding to launch - updates were just emailed
[16:54:21] <kaseycantwell> he conditions at Richardson Ridge were better than at the other sites this morning. That being said, we are still keeping a very close eye on the winds and waves, and may need to recover if they increase. For now though- we are planning on an approximate 13:00 EDT launch. In other good news, provided that the conditions cooperate, we will be able to extend this dive by two hours! An update time table is in my most recent email and we will talk to you soon.
[16:56:20] <scottfrance> Good news.

[17:54:34] <scottfrance> So - did tar sponge have spicules?
[17:54:48] <scottfrance> that is - was it in fact a sponge?
[17:56:48] <cherylmorrison> We didn't feel any spicules in the black part, but there was an inner portion that looked more typical sponge-like that had spicules. We kept the genetics samples of the black vs. tan portions separate since we weren't certain they were the same sponge.
[17:57:34] <scottfrance> Interesting. You could see in the video yesterday that the "tissue" or surface in the holes looked different from the smooth exterior.
[17:58:53] <cherylmorrison> Yes! Guessing they are parts of the same organism, but it will be very interesting to investigate further!

[18:08:50] <scottfrance> We had the same experience last year coming out of American Samoa (as Kasey can attest). It was alomst as if we were on a lake rather than the ocean, at least until we crossed the equator. Then the seas picked up as we headed into currents.

[19:10:06] <mikeford> The little jelly from a few minutes back is a Rhopalonematid.  It will require some review to confirm all of this.   The quick look here had a short sequence of the partially pendant gonads on the radial canals which suggest a species in the genus Crossota (maybe Crossota alba) rather than Benthocodon.
[19:10:44] <mikeford> Neat that this jelly was just off the bottom.  Not the first time we have seen interesting jellies just off the bottom.

[19:25:27] <sandrabrooke> I think this urchin is actually an Echinod (Echinus?) rather than an Echinothuroid (pancake urchin)
[19:25:32] <johnreed> Urchin- Aerosoma? We've  seen frequently on the FL-Hatteras slope with JSL
[19:25:45] <joanaxavier> They look really interesting
[19:25:55] <joanaxavier> oh wow!!!!
[19:26:10] <joanaxavier> actually I'd be very interested in having one or more of those
[19:26:31] <joanaxavier> This is a very interesting species
[19:27:29] <rachelbassett> @Sandra @John I've been annotating this urchin as Echinoidea. Do I need to change it?
[19:27:32] <johnreed> Sponge- Aphrocallistes beatrix
[19:27:38] <cherylmorrison> @joana, the pilots are struggling with current and don't think they can collect here. Hope we see more in a safer place
[19:27:43] <joanaxavier> So, both these species are ASPIRE targets for connectivity studies
[19:28:10] <andreaquattrini> has anyone done any barcoding on the "Duva florida" in this area? I am just not sure about the id.
[19:28:13] jillbourque leaves the room
[19:28:28] <cherylmorrison> I think we've seen both Aerosoma pancake urchins and Echinus urchins
[19:28:39] <enriquesalgado> Those glass sponges- Family Rossellidae
[19:29:02] <joanaxavier> The sponge of the left, which seems to be rather abundant is likely to be Vazella pourtalesi

[19:35:09] <cherylmorrison> I believe the pinkish clump is a contracted Duva florida
[19:35:30] <johnreed> Re: red shrimp- Scott could this be Pleoticus robustus, royal red shrimp?  There is a deepwater trawl fisheries that trawl within the DeepCoral HAPC- should be banned.
[19:35:46] <rachelbassett> @Cheryl Thanks. It almost looked like a cluster of eggs of some sort.
[19:36:34] <lesliesautter> @rachel - sorry. pilot watch change and now current taking us away to next stop.
[19:38:02] <scottfrance> @Andrea: just back to my computer. Not sure if anyone has barcoded Duva from around here, though we did make the collection the other day so one will be done.
[19:38:21] <andreaquattrini> yes, i will request it scott

[19:40:05] <andreaquattrini> fun video
[19:40:32] <johnreed> More live coral on this south side of the mound- That is typical of all these Lophelia mounds off SE US as they grow into the current.  Only difference are mounds at foot of Miami Terrace, where a persistent countercurrent on the bottom has the corals growing on north slope there.
[19:40:45] <andreaquattrini> yes i think so
[19:42:14] <rachelbassett> He's adorable!
[19:42:19] <sandrabrooke> @Andrea. I referred to the Neptheids as Duva yesterday, but I think it more likely they are Pseudodrifa cf nigra

[19:45:24] <scottfrance> @Andrea: I sent Cathy 5 or 6 specimens collected from deeper on the slope (2500 m) to the north, so if you haven't already looked at them, they should be available.
[19:46:19] <andreaquattrini> @scott i will ask her. and i will get her eyes on the video this afternoon

[20:22:27] <erikcordes> we cored a mound in the Gulf - 16m of all coral and the skeleton at the bottom was 300k yrs old
[20:23:15] <erikcordes> the total mound depth, from the seismic data was about 20m

[20:25:59] <kensulak> Just joined the dive and scanned back to see what fishes were encountered:  Small mottled pattern skate = Fenestraja plutonia (the tail is held absolutely straight to avoid distorting the electric field used in electroreception); the coral hake is Laemonema melanurum – and the small transparent juvenile morid seen early on in a pit may be the young stage of the same; what appeared to be a Chaunacid angler fish is not an angler at all, but a scorpionfish relative, Cottunculus microps (note no lure and no pit on the forehead) – good example of convergent evolution to a common body form.  The flat and friendly gray with black markings angler fish is a species of genus Lophoides (have to check on species ID since 3 very similar species like to inhabit coral rubble).  Lophoides may be considered highly associated with Lophelia rubble, but not with live coral.  Probably all of the synaphobranchid eels seen are S. affinis.
[20:27:58] johnreed leaves the room
[20:28:32] <scottfrance> You've probably said this and I missed it (lots going on here today): how high is this mound feature relative to the adjacent seafloor? That is, what is the vertical relief? 40 m? 80 m?

[20:30:26] <charlesmessing> The feather star crinoid is Zenometra columnaris. The extremely long cirri (hooks) arranged in columns, and the arms ending in slender filaments are characteristic. Like another amphi-Atlantic feather star seen the other day, Pentametrocrinus atlanticus, Z. columnaris occurs in much shallower water in the western Atlantic (~~500-1000 m) than in the eastern Atlantic (~~3460-4015 m).

[20:49:56] <kensulak> There is a fundamental difference between Blake Plateau/Scarp Lophelia ‘mounds’ an the best developed Lophelia mounds at 350-500 m depth on Viosca Knoll.  In the Gulf, the 1-2 m tall Lophelia thickets are mostly alive (white) and perched about a relatively thin (1-15 m deep) accumulation of dead eroded Lophelia branches.  The Gulf colonies have very little dead brown-gray Lophelia rubble surrounding the live thicket.  Close-up photography by USGS showed that what branches do die and fall to the substrate are rapidly degraded – suggesting dissolution in an acidic benthic boundary regime.  The thickets themselves rest not on hundreds of meters thick Lophelia rubble, but upon the tops of salt domes.  In contrast, as shown be bottom-penetrating sonar, the Lophelia mounds on the Blake Plateau accumulate up to hundreds of meters thick, built entirely of Lophelia rubble (and trapped sediment) with a living white veneer.   What we have seen today and on the previous dive are extensive thick la
[20:50:59] <kensulak> yers of dead Lophelia
[20:51:05] <scottfrance> @Ken: very interesting - thanks.
[20:51:19] <scottfrance> Is this an oreo?
[20:52:02] <sandrabrooke> Looks like an Oreo
[20:52:13] <kensulak> Scott - Yes and oreo - Neocyttus sp.
[20:53:28] <kensulak> Regarding Lophelia mound formation, what occurs in the eastern North Atlantic is exactly like what we are seeing today, extensive fields of rubble eventually building into a very thick elevated mound with a living crust

[21:05:03] <nolanbarrett> @Leslie You answered my question about what happened to that face of flattened coral rubble before I could ask it. Its amazing to think that these mounds are made of literal tons of this biogenic material.
[21:05:26] <kensulak> Oreos are not closely related to damsel fishes.  They are members of a distinct group of fishes, the Zeiformes, mostly known from upper and middle slope depths.  Many have stout and prominent dorsal, pelvic and anal fin spines.  Antigonia is another Zeiform genus that we might encounter at today's depth - and is another that munches coral polyps along with tiny crustacean commensals perched on corals
[21:06:01] <lesliesautter> @nolan - I'll ask the pilot to get a wide view of this section of the ridge. after we sample
[21:06:41] <tinamolodtsova> no black corals so far?
[21:06:45] <charlesmessing> Crinoid is Zenometra columnaris.
[21:06:59] <scottfrance> @Nolan: thinking about how long it takes this to grow gives an appreciation for how long these corals have been out here. Long before humans got here.
[21:07:37] <cherylmorrison> @chuck- crinoid collection?
[21:07:45] <scottfrance> @sci: what will specimen number be? (for me to enter in SeaScribe)
[21:07:55] <nolanbarrett> @Leslie That would be cool. It would be interesting to see the extent of the flattened rubble.
[21:08:02] <lesliesautter> 01BIO
[21:08:21] <nolanbarrett> @Scott Indeed. Simply extraordinary!
[21:09:18] <charlesmessing> We only have Pacific representatives of this crinoid family in the ongoing molecular phylogeny, so a collection of Z. columnaris would be helpful. It is the only representative of the family in the Atlantic.

[22:00:35] <nolanbarrett> All of those Ophiurioids on the bottom are waving their arms "Wait come back!"
[22:00:39] <tinamolodtsova> @scott, it is not a reef as the are ahermatypic)
[22:01:10] <nolanbarrett> Possible bryozoan to the bottom left
[22:02:03] <andreaquattrini> there was a paper published in 2007 documenting the sublethal injury in Ophicantha bidentata on Lophelia reefs, suggesting that they may be an important trophic resource as 60% were observed with some sort of injury and regeneration.
