[10:11:48] When we arrived on station this morning at the target dive site for Dive 4, located south of St. Croix, weather was still rough. As a result, the team decided to try an alternate dive site located ~~12 nm to our west in a more sheltered location in hopes of finding better weather. Dive 4 is thus delayed by at least one hour. Stay tuned [10:26:39] danielwagner leaves the room [11:50:11] danielwagner leaves the room [11:52:57] taraluke leaves the room [12:02:14] chat-admin leaves the room [12:02:15] danielwagner leaves the room [12:10:50] staceywilliams leaves the room [12:23:01] Weather still not looking good, with high winds, seas and lightning. We will postpone the pre-dive call until we know whether we can dive today. Stay tuned. [12:35:19] staceywilliams leaves the room [13:22:48] Thanks Daniel. I'll keep checking back in [13:26:35] danielwagner leaves the room [13:38:38] Weather conditions are improving, so we proceed with the dive. We are still ~~1h away from launching, but will keep you updated [14:04:25] chat-admin leaves the room [14:05:12] EX1811 DIVE04 Test message [14:09:34] colleenpeters leaves the room [14:11:37] emilycrum leaves the room [14:15:10] danielwagner leaves the room [14:16:28] staceywilliams leaves the room [14:29:25] We will start the call in a couple moments. Just setting up the connection now. [14:30:02] ROV deployment will occur in about 15 minutes and we should have a brief transit to the bottom.

Obviously not on the call but following on camera 3. I just missed what the depth would be. [14:39:00] 570-405 [14:39:13] Thanks [14:40:44] Good morning Scott [14:41:42] EX1811_DIVE04 ROV Launch [14:42:05] Morning Tara. Even earlier with time change! [14:45:52] Scott, we were discussing that today. I know for EST/CST folks the planning meeting at 8:30 AST is quite early. We will try adjusting that time to be more reasonable where we can (eg. after launch on deep dive days) [14:46:56] Much appreciated! But that is why I try to be on the post-dive call because I know the logistics often make it difficult for me to be on in the morning. [14:49:28] danielwagner leaves the room [14:50:25] EX1811_DIVE04 ROV on Surface [14:51:27] For me it's the opposite. My daughter gets on the school bus at 7:02, so 7:30 works fine here. It's the afternoons when it gets a bit tricky for me.

This is something that I'm happy to discuss with everyone in the morning and afternoon calls from now on. We want to maximize participation so whichever way we can adjust things, let us know. We have more room to play on deep dives than shallow dives because of transit time.

[15:53:45] ok [15:56:50] Thanks for all the help annotating scientists! Remember, there's no such thing as too many annotations! Also, note, the [15:57:02] video gets chunked into 5 minute segments [15:57:22] So if the imagery stays on one scene for 3-4 minutes, please feel free to re-tag if there's nothing else going on.

[15:59:54] @asako, no, just passed by [15:59:57] @Asako: I don't recognize it. [16:00:22] @scott I'm slowly learning :) [16:00:38] There are small snails that feed on them, but they are very small and would be found on arms in different places. [16:00:53] You missed the yellow blob! [16:01:42] We're in the midst of a pilot change [16:01:59] Thanks @Tina, @Scott. I mean not only this dive but also previous dive or past cruise. [16:02:11] It was 1 m or so to right of crinoid. My fault for not being on the phone. [16:02:42] LAT : 17.589662 , LON : -64.88868 , DEPTH : 537.1801 m, TEMP : 10.40221 C, SAL : 35.22542 PSU, DO : 3.74861 mg/l [16:02:53] @Asako: right. that was my answer - I don't recognize it, but I'm not great at IDing Chrysogorgia, especially at this depth. [16:03:44] greeneye? [16:04:12] I'm not a fish person, but that was my first thought, too [16:04:24] @Scott: Thank you! I'm not good at ID Chrysogorgia too especially at this region... [16:05:05] @Steve: FYI, we've seen 2 of the Chrysogorgia and they appear to be in soft sediment... [16:05:23] Sea robin? [16:05:44] oh, is not it is pretty... [16:06:12] just a mess between fish and crustacean [16:07:31] Excellent! This is the same as the yellow blob I saw earlier. [16:07:43] LAT : 17.589672 , LON : -64.888603 , DEPTH : 533.6353 m, TEMP : 10.45213 C, SAL : 35.23159 PSU, DO : 3.74533 mg/l [16:08:07] can we pock it? [16:08:17] Wow. Polychaete would not have been my first guess. Cool. [16:08:34] we could. want to? [16:08:47] we will see more [16:09:22] yes... it has to escape nicely.. with some tentacles left... [16:09:46] For the record, it wasn't confirmed to a genus or species level. So unknown ID [16:10:12] Wait! Maybe that IS the same yellow blob, since there is the crinoid again on its left... [16:10:43] my video has delay...

I can't recall a dive where we have seen so many in a short period of time. [16:17:44] LAT : 17.589762 , LON : -64.888654 , DEPTH : 527.5004 m, TEMP : 10.60088 C, SAL : 35.25351 PSU, DO : 3.74168 mg/l [16:18:23] I'm at home for once… no firewall! [16:18:48] Hi Chris. Not sure if you saw my previous comment: Interesting how many urchin tests we are seeing. I can't recall a dive where we have seen so many in a short period of time. [16:19:08] yeah… I was noticing those. it makes me wonder. [16:19:16] And a couple of live ones to boot [16:19:39] I had to do a double-take. I saw Chris Mah in the chatroom [16:19:50] *laugh* yes. [16:19:57] Welcome :)! [16:20:09] slower connection at home for video.. but chatroom works1 [16:20:29] danielwagner leaves the room [16:20:29] @chris there is a sea urchin:) [16:21:10] the red one..I see it on the ROV screen but not on feed1 [16:21:52] an irregular I think [16:22:16] but I'm still lagging….looking at the small screen [16:22:44] LAT : 17.589796 , LON : -64.888507 , DEPTH : 524.964 m, TEMP : 10.61752 C, SAL : 35.25402 PSU, DO : 3.74256 mg/l [16:23:43] hmm.. okay don't recognize it.. will need to look it up.. but I'm at home. [16:24:13] yay, hard bottom! [16:24:32] just joining. looked back at fishes seen so far: fat orange fish is not a toadfish, but a toadfish-look-alike = genus Chaunax, a 'gaper'; another fish is a greeneye-look-alike, not a greeneye but genus Bembrops gobiodies; angler is Lophiodes, probably species L. reticulatus. Regarding the frills around the head, they are camo, break up the body outline. If you dim the lights you will see the camo effect which is much more effective over mixed substrate [16:26:23] As always, great info Ken. Thanks. [16:27:08] The greenish eyes in both actual greeneyes, Chlorophthalmidae, and in Bemprops, serve to emphasize wavelengths other than the predominant blue that eeks down to this depth and is also produced bioluminescently. Green or yellow filter in eye allows it to somewhat counteract the red or orange camo coloration of fishes at this depth - as in the gaper [16:27:45] LAT : 17.589932 , LON : -64.8886 , DEPTH : 519.5169 m, TEMP : 10.63605 C, SAL : 35.25925 PSU, DO : 3.74354 mg/l [16:29:57] The broken gravely, shelly substrate around the red urchin would be a perfect camo background for Lophioides angler fish [16:30:57] Another possibility is something like Pinnidae (pen shells), which are mussels they live partially buried. But I don't know what depth range they inhabit. [16:31:20] staceywilliams leaves the room [16:32:28] In the super clear Caribbean oceanic seawater, ambient sunlight survives to almost 1,200 m in intensity (photos per unit area) to be sensed and used by fishes. The really big eyes of Chlorophthalmus and Bembrops suggest they do indeed utilize that miniscule ambient light from above. [16:32:45] LAT : 17.589974 , LON : -64.888535 , DEPTH : 517.5453 m, TEMP : 10.70103 C, SAL : 35.24982 PSU, DO : 3.73385 mg/l [16:33:03] Acesta bivalves? [16:33:42] Acesta are those flattened bivalves in the wall? [16:33:50] mashkoormalik leaves the room [16:34:01] Yes, quite common on walls in canyons [16:34:17] Google them for images [16:36:49] danielwagner leaves the room [16:37:46] LAT : 17.589947 , LON : -64.888493 , DEPTH : 515.2023 m, TEMP : 11.0056 C, SAL : 35.30142 PSU, DO : 3.75687 mg/l [16:39:04] Perhaps the Acesta falling from the walls after death [16:40:10] bronzish roughy-like fish = related genus Hoplostethus. fish being munched by squat lobster is a midwater fish, possibly the pearlside Maurilicus meulleri. These midwater fishes often occur near the substrate. Those you see getting munched during an ROV dive have generally been damaged by the ROV thruster. Normally, they would not be caught by a squat lobster - unless so disabled [16:42:14] small blue fishes with big black eyes hovering close to rock face = Epigonus [16:42:46] LAT : 17.589959 , LON : -64.888579 , DEPTH : 511.0552 m, TEMP : 11.18278 C, SAL : 35.3312 PSU, DO : 3.7641 mg/l [16:43:59] Lots of zoanthids [16:45:53] Pretty interesting to see this complete take over of the skeletons by zoanthids... [16:46:14] Makes me wonder how old those initial colonies are (or rather, how long they have been there) [16:47:25] Note how the colonies are aligned on the least eroded part of the wall. [16:47:44] I wonder if the holdfasts are protecting the carbonate to some degree from erosion... [16:47:55] LAT : 17.589996 , LON : -64.888525 , DEPTH : 509.1731 m, TEMP : 11.22794 C, SAL : 35.34362 PSU, DO : 3.74881 mg/l [16:48:10] ...or if instead that is the densest part of the wall layer and that is where the only settlers have survived. [16:48:32] irissampaio leaves the room [16:49:08] Look at the white thing on the Stichopathes (left) [16:49:23] Ophiuroid or chirostylid? [16:49:29] I will try to get back there. [16:50:39] I think it was a brittle star scott. Arms extended [16:50:51] Scott - steep, eroded layered carbonate looks very similar to topography we saw in 2009 on your deep Bahamas ROV cruise, but at much greater depth [16:51:07] @Ken: agreed. Lots os similarities. [16:51:15] *of [16:51:52] another Sticho with white leggy thing [16:52:05] To the left... [16:52:18] I think it is an ophiuroid, but different from others [16:52:36] Forget the name of these fishing ophiuroids [16:52:47] LAT : 17.589975 , LON : -64.888523 , DEPTH : 505.6464 m, TEMP : 11.31724 C, SAL : 35.35924 PSU, DO : 3.78952 mg/l [16:53:25] These are really common on sea pens in the Aleutians [16:53:43] Good target for collection then? [16:53:54] Hmm - ignore commensal fish hiding is sponge - but zoom in on slitshel?? Unscientific bias [16:54:06] I mean the Stichopathes/ophiuroid pair [16:54:20] I was talking to Dan about that. Stichopathes really need to be collected for ID. If you support it I second a collection of the duo. [16:54:46] Absolutely I support a collection - IF it comes with the ophiuroid. [16:56:55] Possible genus for ophiuroid: Asteronyx [16:57:16] small slender bluish fish with deeply forked caudal fin seen here and earlier may be an Argentinid [16:57:42] Or at least Asteronychidae [16:57:52] LAT : 17.58999 , LON : -64.888519 , DEPTH : 500.4862 m, TEMP : 11.39296 C, SAL : 35.37154 PSU, DO : 3.78495 mg/l [16:59:38] Good comparative image: http://www.godac.jamstec.go.jp/bismal/e/view/9000247 [17:00:27] Fish hanging out vertically along wall face [17:00:52] I have to leave for a while.

[18:06:55] fish is indeed a true Greeneye, Chlorophthalmus agassizi. Note the blotched pattern of dark saddles and short snout. The rather similar look-alike seen earlier lacks the blotches and has a long snout and dark margins on the fins.

It looks most similar to large colonies of Acanthoprimnoa I've seen in this area. Polyps are alternating on each side of the branch but I've never seen one this large.
