[14:34:44] @Cheryl maybe there are short spines... not clear for me [14:36:31] Excellent close-up of halosaur and the red-purple Phormosoma? pancake urchin. There is a commensal relationship of juvenile ophidioid Barathrites with such urchins. Might find a juvenile Barathrites so sheltering at some point. Fish and holo fauna here is very typical of highly oligotrophic tropical Caribbean deep seafloor. Ipnopids are sedentary, low energy-expenditure sit and wait consumers. There are also hermaphroditic, both male and female simultaneously, which is advantageous when individuals are very widely separated in space. Whomever you meet is a potential partner. [14:37:05] Great info thanks @kensulak! [14:38:14] LAT : 17.844784 , LON : -64.613995 , DEPTH : 1776.335 m, TEMP : 4.14441 C, SAL : 34.97579 PSU, DO : 7.16588 mg/l [14:39:58] Thick sediment deposits on the slope here with little evidence of downslope movement [14:40:47] Interaction has finished on channel 3. Should be reverting back to normal configuration now. [14:41:02] Ipnopids have de-emphasized or curiously modified the eyes. Eyes are tiny in Bathypterois - depends instead on the satellite-dish like sensory array of pectoral fin rays each of which contains a very large nerve coursing to extravertebral ganglia. Bathytyphlops is blind. Ipnops has the yellow reflective retina expanded and flattened - jury is out on just how this functions. But most probably a lenseless light receptor to detect bioluminescent prey. [14:41:32] Thanks for the excellent information!!!!!!!!!!!!

[14:59:43] @Scott about 25 min ago. 1777 m. it did not have yellowish tissure. [15:01:24] Chute, Scott I wanted to crack that joke [15:01:42] @jason would you like to say anything about the geology of this area? [15:02:03] pilots are concerned about suspended cables that could be in this area so they don't want to go too far in [15:02:15] @Jason: Wall, I'm a failure... nope. I can't think of more geology puns to work in here.

[15:04:03] +1 for the effort on that one! [15:04:58] I am not on the telecon as I am doing some other things, but I can say that the geology here is quite complex, given the impact of the active structures (large offset normal faults) and the extreme vertical relief that it creates [15:06:35] St Croix, like Puerto Rico and the other Virgin Islands are cored by Igneous rocks intruded during early phases of volcanic activity and then covered by (or now rimmed) by thick carbonate platforms [15:07:45] the area you are in is adjacent to a transition between the greater antilles (volcanically inactive) and the lesser antilles (volcanically active) so there are overprints of many different processes [15:08:17] LAT : 17.844134 , LON : -64.614121 , DEPTH : 1753.9815 m, TEMP : 4.22599 C, SAL : 34.9669 PSU, DO : 6.9026 mg/l [15:09:27] specifically here though, the thick sediments "stuck" to the steep slopes are interesting in that there isn't much evidence that they have moved downslope even though the area is seismically active...from a geohazards standpoint, that is information we use to evaluate the impact of earthqauke shaking and things like tsunami generation [15:11:27] It was hypothesized that beaked whales were making scars like this at deeper sites off the SEUS [15:11:43] Could be a furrow made by diving beaked whales, according to Les Watling. [15:12:05] I have seen beaked whales inbetween St Thomas & St Croix [15:12:35] Had a great view of Mesoplodon densirostris! [15:13:18] LAT : 17.844034 , LON : -64.614086 , DEPTH : 1746.6461 m, TEMP : 4.21092 C, SAL : 34.97317 PSU, DO : 6.86428 mg/l [15:13:30] That is really cool @kevin! [15:13:36] They may be picking squid off the bottom. Illex are known to rest on the b ottom [15:16:03] Aldrovandia [15:16:38] Would love to see a beaked whale chase after squid down here, but I suspect they avoid the "noise" of the ROV. Or we are just very unluckly given how many scars we've seen over the years! [15:17:04] @Scott That would be way cool!! [15:17:11] Aldrovandia affinis, dirty white with darkish snout tip. No need to look for head scales. At this depth and in this region the other genus Halosaurus is very unlikely. But the thick-bodied, jet black large Halosauropsis is in the area, however mostly deeper [15:17:31] Looks like a sea pen [15:18:04] Thanks Ken!

[15:19:39] @Scott What are the short stubby structures in between the tentacles of each polyp? [15:19:45] Possibly Anthoptilidae [15:20:15] @Nolan: probably siphonozooids, modified non-feeding polyps. [15:20:38] The base will be a "bulb" (peduncle) that anchors the colony in soft sediment [15:20:59] This one also has a single stiff rod in the main axis [15:21:32] That mysid may have had a clutch of embryos [15:23:05] Or Protoptilidae [15:23:19] LAT : 17.843803 , LON : -64.614027 , DEPTH : 1738.4265 m, TEMP : 4.20642 C, SAL : 34.97372 PSU, DO : 6.92288 mg/l [15:27:51] @Scott Had to run out for a sec.

My bad. In fact, I was wondering about those as well - almost like a double row of tentacles. But if I had to guess (and I do) I would say they are sclerites pushing up tissue. I'll definietely need to go back to those images to take a closer look. [15:29:13] Roland Brian leaves the room [15:30:07] @Stacey I just emailed the sponge pictures from yesterday. Turns out Shirley Pomponi is on vacation until Nov 30, so we may or may not hear from here. But I also sent them to Joana Xavier and Chris Kelley, so hopefully we can get some tenative IDs for the demosponges. [15:31:26] @Scott Oh haha, I was none the wiser! Yes, thats exactly what I was talking about. Have you seen those before on other specimens? The tips of them looked rounded and not sharp, so I wasnt sure if they were sclerites or not.

[15:36:51] Lots of zoathids on the stalk. [15:37:06] @Scott Okay! Good luck! [15:37:17] *zoanthids [15:37:28] Actually, these may be anemones, not zoathids... [15:37:37] Squat lobster at base [15:37:54] They look very similar to ones we found in Oceanographer canyon. I think the genus name was Synathus. Will need to check [15:38:17] Stalked Euplectellidae [15:38:28] LAT : 17.843362 , LON : -64.614192 , DEPTH : 1728.1865 m, TEMP : 4.21947 C, SAL : 34.97369 PSU, DO : 6.81071 mg/l [15:38:43] Typically we see zoanthids colonizing these stalks, so not sure the conditions under which anemones get the upper hand. [15:38:43] megancromwell leaves the room [15:39:17] The columns of these polyps look transparent, another thing that leads me to guess anemone and not zoanthid.

[17:15:21] Sorry - Metallogorgia [17:15:37] ooohhhh [17:15:46] yippee [17:16:10] It is not a "full grown" one as you can see still some intermediate branches [17:16:41] we will go back in a moment. Just clearing the sediment [17:17:29] We have seen (and collected) these tall Metallogorgia in the Caribbean (nearer to Bahamas) [17:17:50] interesting. the main axis was more yellow than dark.

Bathysaurus has large very capable eyes. Both are sit-and-wait predators of large mobile megafauna like shrimps and smaller fishes. In this biological desert, nearly devoid of mobile megafauna, no energy is wasted in searching or pursuing. Anything that ventures too close to the business end will get engulfed in a short lunge forward, capacious mouth instantaneously opening and snapping shut. [17:19:12] Anyone interested in collecting this for Joana or Chris K?

[17:26:18] We were not able to return to the Metallogoriga [17:26:34] This is what happens when one keeps having to walk away from the monitor. [17:27:34] Interesting story/question here about how many larvae are out here. Just the lucky ones find these bare rock faces, or are they very persistent long-lived larvae...

I'd say a bamboo coral [17:31:35] Theres another larger one to the top right when zoomed out. Its against the black background of rock.

Do you think there would be concerns about optics for discarding part of the coral to sample the bryo? particularly considering that we're in a protected area [19:02:08] No, because the coral is dead. [19:02:23] It was a dead skeleton being overgrown. [19:02:35] At least, that is what I saw. [19:03:35] Right. It was only hydroids. I'll keep an eye out.
