But they represent a small fraction of the overall environment on land or in the ocean. Much of OE effort to date has focused on seamounts. Getting less attention, but perhaps equally important as habitat for diverse organisms (not only corals and other sessile epifauna) are ecotones, transitional edge habitat. Perhaps OE might give consideration to some missions particularly focused on the ecotone between the open sedimentary abyssal plain and the base of seamounts and ridges. Would not be as rich in corals and sponges, but would be richer in terms of mobile (crawling and swimming) megafauna - and give appropriate attention to these extensive and important transitional biotopes/habitats. Just a suggestion to consider from an old deep-sea biologist.

I think maybe that was Ventrifossa [15:57:50] an amazing field of Metallogorgia [15:57:55] morphologically as well [15:58:11] Paramuricea [15:58:42] very nice contracted polyps right [15:58:46] LAT : 39.838168 , LON : -66.229466 , DEPTH : 1924.905 m, TEMP : 3.68281 C, SAL : 34.95097 PSU, DO : 6.29397 mg/l [15:58:50] Asteroschema? [15:59:11] worm at the base? [15:59:41] AKen - thanks - I've seen Nezumia behave like that off bottom and when disturbed ... but will check the stills/video post-dive [15:59:54] b star has been identified as Asteroschema clavata from previous samples, might have the species wrong... [16:00:56] chris, it was a weird brittstar [16:01:04] at the base [16:01:18] very small disk [16:01:29] thanks Tina.. hope we can zoom close next time. [16:01:59] Can't tell if I'm seeing a carpet of sponges or sediment pockets [16:02:18] Sediment pockets, I think [16:02:20] can we zoom at sediment? [16:02:21] gravel covered sediment plain [16:02:38] urchin! [16:02:53] something-some [16:03:17] Look for the juvenile cusk eel! [16:03:41] @ChrisM if you want to play with these brittle stars I have several hundred in my lab that we have collected from these seamounts [16:03:46] LAT : 39.838172 , LON : -66.229613 , DEPTH : 1924.1729 m, TEMP : 3.68521 C, SAL : 34.94812 PSU, DO : 6.56783 mg/l [16:03:56] Check out the recruit to left front of urchin! [16:03:59] this one is toxic? [16:04:04] Acanthogorgia, I think [16:04:58] I think perhaps what I said were sediment patches are actually all xenophyophores. [16:05:02] pen [16:05:04] Sea Pen! [16:05:14] some-pen [16:05:17] Penntula/Ptillela like [16:05:28] *Pennatula [16:05:48] NOT a rock pen. :-) [16:05:50] what a lot of xenophyophores... [16:05:51] yes .. :) [16:06:10] I have to check [16:06:16] Good eye on the aplacophoran earlier! I called in to say hi but I'm always too slow on the draw. Just to comment on the names, Aplacophora is a higher-level group that includes two sub-clades. Solenogastres is the group y'all pretty much always see that live epibenthically and can commonly be found on corals and hydroids. There is another group that mostly burrow called Caudofoveata. [16:06:18] @Rhian: believe it or not, while you were at lunch we saw a rock pen! [16:06:26] actually number of rows is a character [16:06:40] would love to suction those mysids! [16:06:45] No...did you realy??? [16:06:50] We did. [16:06:54] Really. [16:07:00] Tucked under a ledge [16:07:15] back ridge is also a characteristic [16:07:18] @les, but you need to be focused on corals) [16:07:38] @vonda, but we have seem leaves) [16:08:10] @Kevin: thanks for chiming in!

I'm always happy to ID any aplacophoran specimens collected and material in RNAlater would be super useful for my NSF career project :D [16:10:32] seapen [16:10:59] can we up zoom? [16:11:13] Chiming in late, but this is a different species from the ones seen earlier [16:11:25] Halipteris? [16:11:32] halipteris? [16:11:50] you need to look at polyps to be sure( [16:12:23] looks like a halipteris, the video is very grainy on my end, so could not see it clearly [16:12:49] Video getting choppy here as well. [16:12:53] @Scott - looks like it. It has changed to Balticina (= Halipteris) I believe [16:12:57] choppy video [16:13:08] mine is worse. choppy video and pixelized [16:13:13] I have no video at all for the moment( [16:13:22] I won) [16:13:37] I was having video issues for a few minutes but its much better now [16:13:47] LAT : 39.83802 , LON : -66.229776 , DEPTH : 1920.7235 m, TEMP : 3.69936 C, SAL : 34.94053 PSU, DO : 6.49002 mg/l [16:13:59] )) [16:14:04] Thanks Vonda. I clearly have some catching up to do on my sea pen taxonomy! [16:14:08] we've become very spoiled by the superb video [16:14:20] I have reported it [16:14:28] not like in the olden days.... [16:15:33] hope it will be OK video in seatube( [16:15:38] looks like a more unstable slope than where the corals were as well [16:16:05] still some Xenos, but less [16:16:09] They are assessing the video onshore - hope it comes back too! [16:16:26] coral! [16:16:31] or else [16:16:37] paamuricea [16:17:32] If there exist Placogorgia, I cannot distinguish it with Paramuricea in the video.. [16:17:40] jasonchaytor leaves the room [16:17:40] abother sea pen [16:17:50] @Asako: agreed!

I'm wondering if we have moved into a current shadow... I wouldn't have expected that on this bottom feature. I figured the currents would wrap around it. [16:19:49] Have cobbble, will settle. [16:20:02] Port in a storm. [16:20:14] heatherjudkins leaves the room [16:20:27] bouquet community [16:20:36] @Scott - we are on our track [16:21:10] @Scott: I never heard anyone mentioned Placogorgia in the ROV dives, but they exist.. [16:21:16] @Rhian: I didn't mean to imply we drifted off track. I meant does the track cross to east or west (or north or south) as we rise? [16:21:31] kimberlygalvez leaves the room [16:22:08] N-S [16:23:07] @Rhian: I'm just trying to get a sense of whether we have moved behind an obstruction, so to speak, relative to where we started. This will come out post dive when we have more tools to compare dive track with topography and video.

[16:24:27] @Scott - yes, I don;t think we have, I think we've just hit a flat spot on the track which was expected, though admittedly lower [16:24:35] jaymesawbrey leaves the room [16:24:52] Odd looking rock... [16:24:59] Sponge coated? [16:25:16] encrusting sponge [16:25:30] @Rhian: right. Need to keep being reminded that the actual bottom is more complicated than the smoothed maps! [16:27:07] vondawarehamhayes leaves the room [16:27:14] heatherjudkins leaves the room [16:27:22] I think we are in some sort of chute-like environment, more open slope morphology to it [16:28:21] Chrysogorgia, I think. [16:28:33] Havent had a CU of them yet today. [16:28:46] Ooh! Forked forked whip!!

[16:36:04] jocelyncooper leaves the room [16:36:12] yeah, there should at least be Candidella imbricata, which was pretty much everywhere in the neighborhood [16:36:42] This seamount is obviously a good place for Acanella! [16:37:34] @Scott - prior to this expedition have you seen Acanella on rock like this? We never see it up north... only on soft muds! [16:38:11] @Les: Parastenella atlantica was described from here at 1984 m depth. As far as I know, it is the only know locality for that species. [16:38:20] @Vonda: absolutely [16:38:32] kelseyviator leaves the room [16:38:47] poor video again, if that helps the troubleshooters on shore [16:38:51] LAT : 39.837645 , LON : -66.230095 , DEPTH : 1898.7854 m, TEMP : 3.71016 C, SAL : 34.95323 PSU, DO : 6.25884 mg/l [16:38:52] @Vonda: we've seen this a lot her in western NES. Very cool how it can transition between rock and sediment [16:39:12] I'm frozen on a lovely view of many Acanella [16:39:24] me too [16:39:45] my is still fine with solitaly hidroids, Acanella, crinoids, [16:39:46] moi aussi [16:39:48] nice ydroid: [16:39:55] Relaoding the page helps. [16:40:21] cindyvandover leaves the room [16:41:14] thanks - woul have taken me forever to think of that. Much better [16:41:20] cindyvandover leaves the room: Replaced by new connection [16:41:23] Perhaps some shaggy Acanthogorgia on right... [16:42:05] @Cindy: I periodically reload the page - at least once every 20 minutes. It really helps pick up the lag (important if tyou are on the phone) [16:42:23] vondawarehamhayes leaves the room: Replaced by new connection [16:42:36] my phone keeps locking up even when the laptop does not [16:43:50] LAT : 39.837748 , LON : -66.230037 , DEPTH : 1897.8462 m, TEMP : 3.70632 C, SAL : 34.9556 PSU, DO : 6.02099 mg/l [16:44:48] It is more pink in color than the other ornage ones. There are several species of Acanella, so not impossible it is different. Although based on collections to date, all NES Acanella appear to be A. arbuscula. [16:45:26] its crinoids tree! [16:46:06] those darn crinoids.... leave my coral alone! hahaha [16:46:25] any chance it could be a seasonal aggregation of crinoids for repro? [16:46:26] christophermah leaves the room [16:47:49] we have seen these aggregations before, but don't remember whether there was any seasonality... I think they like these intermediate depths [16:47:51] @Cindy: now that is a cool idea. Certainly is known for sea cukes.

[16:49:53] @Jason: are you sure you are not from Texas. Bigger always seems to be better for you. [16:50:55] kimberlygalvez leaves the room [16:51:02] I like to make things difficult for those that have to ship and store all the rocks :-) [16:52:14] And take them out of rock box and weigh them and tag them and... Easy to be the on-shore geologist! :-) [16:53:30] we have seen more forked whips here than anywhere else I think [16:53:53] LAT : 39.837575 , LON : -66.230058 , DEPTH : 1890.7951 m, TEMP : 3.74389 C, SAL : 34.9294 PSU, DO : 6.40304 mg/l [16:53:59] Should we target a collection of a forked whip piece? We porbbaly can't get a fork [16:54:00] The 'hanging' dust cloud from that just hoisted rock suggests we are now in a more quiescent current regime - as does the fine sediment draping some rocks and settling into pockets. Seamounts, interacting with laminar currents can engender large stationary Taylor column vortices over and around the top of the seamount, resulting in a quiescent 'eye' in the center over the peak where the settling of fine particles is promoteda [16:54:35] @Rhian: no, no need. I have collected forked whips from out here. Thanks. [16:55:15] Thanks Scott [16:55:19] Where we have time, a close up of the point where the fork originates is useful to determine if it is a natrual looking branch point or a repair job. [16:55:36] @Rhian, but you could get the tips of the two pieces, if you can keep them separate. That way at least the genetic story could be had accurately [16:56:25] I see @Scott had a different answer... haha... I defer to him [16:56:49] @Rhian: I should clarify that I mean we have collected forked whips from the NES, but not from Retreiver. So I'm making the assumption they are the same thing. [16:57:00] Paragorgia coralloides with zonathids [16:57:14] Stoloniferous octo on rock face [16:57:28] Actually, may be a cornulariid [16:57:46] Thoise octocorals have a tough external coating on the ribbon [16:58:53] LAT : 39.837484 , LON : -66.229974 , DEPTH : 1891.6531 m, TEMP : 3.75084 C, SAL : 34.95563 PSU, DO : 6.45319 mg/l [16:59:19] The only isidids thta have ben collected from Retriever are Acanella and one bramble (not the bramble we saw earlier, which was an "isidella") [16:59:24] Cool! [17:01:13] tinamolodtsova leaves the room [17:02:22] polyps on those branches are different [17:02:45] @Les: volcano-like polyps but with excessively long needles. I don't know that I've seen that before... [17:02:50] main branch looks like B clade, little branch looks like D clade [17:03:03] I think they were the same Les - at least the ones that were open further up that branch. [17:03:11] This could actually be the case of a larva settling on another colony! [17:03:24] the current seems to be bit faster than I expected [17:03:36] I didn't see the long needles on the main branch polyps [17:03:40] Time to plan a repeat trip with the monument folks to do some detailed sampling!@ [17:03:48] lots of knocked over corals [17:03:53] LAT : 39.837473 , LON : -66.230078 , DEPTH : 1889.8183 m, TEMP : 3.74578 C, SAL : 34.94697 PSU, DO : 7.02848 mg/l [17:04:32] love that anemone [17:05:24] why is something so gorgeous living down here in the dark?
