Are you guys being able to annotate? [18:00:18] I am annotating as i take notes... nbd [18:01:55] nope [18:02:21] Large fish = a cuskeel, possibly genus Monomitopus [18:04:15] LAT : 29.862369 , LON : -79.455177 , DEPTH : 804.3163 m, TEMP : 8.57424 C, SAL : 35.1213 PSU, DO : 4.77956 mg/l [18:04:54] cuskeels are not closely related to eels. Imagery here good enough to examine the pelvic fins. blotched eel is an eel - probably family Nettastomidae [18:07:28] more of the yellow demospongiae [18:08:10] can anyone tell me if this data is correct for the adjustment to connect to the annotations SeaTube V.2 page? :resourceTypeId=1000&resourceId=23621&diveId=2103​621&diveId=2103 [18:09:15] LAT : 29.86209 , LON : -79.454725 , DEPTH : 802.0933 m, TEMP : 8.57301 C, SAL : 35.12146 PSU, DO : 4.77672 mg/l [18:09:19] Back to cuskeel pelvic fins - they have 2 rays each in today's fish. So not Monomitopus - since the scientific name means "one-thread". I will look more closely at other details. The eel has a pectoral fin making the genus Hoplunnis, probably H. tenuis which does occur on the Blake Plateau at current depth [18:09:21] mariadiaz leaves the room: Replaced by new connection [18:12:31] @Maria: there is a typo in the link provided in the email this morning. Try this one: https://data.oceannetworks.ca/SeaTubeV2?resourceTypeId=1000&resourceId=23621&diveId=2103 [18:12:45] thanks [18:13:26] Thanks Scott, problem solved [18:14:15] LAT : 29.861815 , LON : -79.454836 , DEPTH : 800.5553 m, TEMP : 8.57312 C, SAL : 35.12171 PSU, DO : 4.76825 mg/l [18:19:16] LAT : 29.862054 , LON : -79.455193 , DEPTH : 796.6075 m, TEMP : 8.58285 C, SAL : 35.12296 PSU, DO : 4.76938 mg/l [18:19:17] One of the values of a dive like today is to show how special the places like we saw yesterday are! [18:22:04] scottfrance leaves the room [18:23:37] Habitat today is what you would expect for the center of the Blake Plateau - illustrates nicely how current-swept area together with deposition of pteropods, forams, and Lophelia rubble yields a continuously growing (deeper and broader) depositional plateau [18:24:16] LAT : 29.861739 , LON : -79.455035 , DEPTH : 797.1812 m, TEMP : 8.57757 C, SAL : 35.12199 PSU, DO : 4.76202 mg/l [18:24:34] Ray is Fenestraja plutonia. Good illustration of effective disruptive camo. [18:26:35] The long tail is more typically held absolutely straight - which corresponds with the fact that this ray uses electroreception to locate prey. Straight tail keeps electromagnetic field undistorted by the fish itself [18:26:54] structure is getting more complex [18:27:43] Very large cuskeel seen earlier = Neobythites gilli, after further review [18:27:48] lets see closer [18:28:24] yes step\ Farrea [18:29:11] clearely we are in an area with less sediment and Hexacts start to appear more [18:29:17] LAT : 29.861604 , LON : -79.455078 , DEPTH : 793.4597 m, TEMP : 8.57511 C, SAL : 35.12127 PSU, DO : 4.76846 mg/l [18:29:38] macrourid = Coelorinchus occa. The official common name for rattails = grenadiers. That name devolves from the British Army riflemen who wore tall pointed hats. Coelorinchus may be the rattail that gave the group its common name grenadier [18:33:00] The gray cutthroat eel with black margin on caudal fin = genus Synaphobranchus, probably S. affinus at this depth and region. [18:33:30] Yes the small ray was a male, but not particularly well endowed - probably a juvenile male [18:33:41] LOL thanks! [18:34:17] LAT : 29.861473 , LON : -79.455107 , DEPTH : 789.6231 m, TEMP : 8.57604 C, SAL : 35.12176 PSU, DO : 4.77083 mg/l [18:35:58] Nice imagery of that rattail, Coelorinchus occa. This species is widespread geographically, but fairly rare. I do not recall ever seeing any subsea images of this species [18:36:12] Bye for today [18:36:18] kennethsulak leaves the room [18:39:18] LAT : 29.861446 , LON : -79.455072 , DEPTH : 789.7643 m, TEMP : 8.57768 C, SAL : 35.12179 PSU, DO : 4.75938 mg/l [18:44:18] LAT : 29.861337 , LON : -79.454849 , DEPTH : 789.8649 m, TEMP : 8.57809 C, SAL : 35.12191 PSU, DO : 5.01744 mg/l [18:44:44] Good JOB!!!

[18:55:41] it looks like on a coral [18:55:50] or styler [18:55:52] Can't quite tell what it is feeding on... [18:56:32] wedding basket Hexactinelid tube?

Just curious [19:04:20] LAT : 29.861119 , LON : -79.454758 , DEPTH : 782.4079 m, TEMP : 8.57137 C, SAL : 35.12134 PSU, DO : 4.87862 mg/l [19:04:41] to the left you can see the blob white sponge [19:05:03] This is mostly a non-biogenic process that occurs. It's mostly to do with the ocean chemistry reacting with skeletal material [19:06:15] Not to discount microbial effects that so occur thsi deep. But most of the crusting is chemical [19:08:54] That purple octocoral is an unknown surprise... [19:09:01] Claocere [19:09:13] Cladocere [19:09:21] LAT : 29.861041 , LON : -79.454825 , DEPTH : 779.7676 m, TEMP : 8.56989 C, SAL : 35.12109 PSU, DO : 4.86728 mg/l [19:10:07] It isn't Clavularia. Must be a purple Paramuricea. Don't believe I've seen that south of the New England Seamounts. [19:12:05] Chrysogorgia [19:13:45] Looks like a chirostylid among the branches- broad, relatively flattend arms. [19:14:19] the crustacean, Tim/ [19:14:22] ?

[19:17:26] hahaha, maybe it's a n old tradition that has died out from over fishing [19:19:22] LAT : 29.860959 , LON : -79.454924 , DEPTH : 774.7635 m, TEMP : 8.57834 C, SAL : 35.12181 PSU, DO : 4.81949 mg/l [19:19:25] It might. I remember reading in Invertebrate books, 30 years ago [19:19:41] It makes a nice old traditional story [19:20:23] Beautiful inmages to the Pilots and videographers [19:20:28] It might be interesting to note that there are many other shrimp (pistol shrimp/snapping shrimp) that form colonies within shallow water sponges, although thay are not trapped there. [19:21:03] Looks pretty healthy! [19:21:11] The polyps are just closed [19:21:38] The yellow one in front was an Acanthogorgia, I think. [19:23:21] I'm also seeing several plume-like hydroid colonies. [19:23:45] when you zoom in, I mean.

And... [19:30:47] Good observation! [19:31:16] I think the pinkish primnoid is Candidella. Check for worm "garages" [19:31:42] ...that is, worms on Candidella induce the coral to deposit sclerites to form tunnels. [19:31:59] Yes! [19:32:12] Looking for areas of the branch that look a little thicker. [19:32:23] Can see it in a few places. [19:32:36] Note a couple on right of colony. [19:32:59] Follow the bright white branch and see where it gets covered in thicker grey [19:33:32] Sorry I am not on phone. Next time!

[19:34:46] Good shot. = Candidella imbricata [19:35:38] I don't recognize this one, but I think it is a different type of primnod [19:36:07] Interesting. Perhaps a sparse branching species of Narella [19:36:23] Nice little collection there! [19:37:13] Hello all [19:37:23] HIEEEEE [19:37:59] Not sure if it is new species. There are so many primnoid species and so many Narella species... [19:38:35] I can't ID them all from in situ and I'm not too familiar with what is known from down here.

The pinnules near the bases of the arms are the last to develop. [20:03:03] These forams appear to be a new species (based on my limited knowledge of the group). The branches are actually supported by glued together sponge spicules, and the white mass in the center consists of glued together tests of planktontic forams. We found this on Lophelia off east Florida during a NOAA OER expedition in 2005 or 2006.

[20:05:16] I havent... @Scott may have [20:05:43] I think whta I was seeing is this Stylaster [20:06:27] The great majority of living crinoids have separate males and females, although a very few species are hermaphrodites. Most release both eggs and sperm into the plankton, although a few brood their eggs on the genital pinnules and wait for the sperm to come to them. Fertilized eggs develop into a little barrel-shaped planktonic larva, which eventually develops a stalk and settles to the sea floor. After developing their little arms, most living crinoids detach from the stalk and take up a free existence as feather stars. [20:06:28] Thanks Stephanie [20:09:27] LAT : 29.860136 , LON : -79.45466 , DEPTH : 761.7846 m, TEMP : 8.57481 C, SAL : 35.11878 PSU, DO : 4.73491 mg/l [20:14:27] LAT : 29.86019 , LON : -79.454881 , DEPTH : 761.5222 m, TEMP : 8.57481 C, SAL : 35.11784 PSU, DO : 4.72616 mg/l [20:14:43] Detachment from the stalk apparently increased their mobility as a means of escaping from predators such as sea urchins and crustaceans. However, in several feather star lineages, the stalk was retained into adulthood via the process of paedomorphosis (PAID-o-morf-o-sis)--the retention of the juvenile feature of an ancestor in the adult of the descendant. [20:16:16] wow, thanks Chuck. That's some great information. [20:17:40] I Hope somene photograph it possibly a Hemimycale species, look at Hemimycalle columnella and orange deep water North Atlantic species [20:19:28] LAT : 29.860138 , LON : -79.454923 , DEPTH : 762.8441 m, TEMP : 8.57593 C, SAL : 35.11718 PSU, DO : 4.7178 mg/l [20:19:41] Definitively this greenish hayry is definitively a Demospongiae, pretty wild [20:20:11] Baby Oceanapia [20:20:16] I lost connection [20:20:21] I will reconnect [20:20:22] If you have a moment for an unrelated question: The other day, we posted a picture of a basket star on a bamboo coral on social media. Jorgri85 on Instagram asked “Do you know if they can reproduce by fragmentation?” [20:21:13] I'm not an ophiuroid expert, but I have read/seen no suggestion that basketstars can reproduce asexually. [20:22:00] I lost connection, too. [20:22:49] I can not hear you gals [20:23:01] I connected again but I can not hear you [20:23:16] on the phone or on the iinternet? [20:23:20] Hexactinellid for sure [20:23:53] I am hearing you in the computer but I called and I am not hearing you on the phone. PHOTO [20:24:28] LAT : 29.860061 , LON : -79.454911 , DEPTH : 763.3796 m, TEMP : 8.57429 C, SAL : 35.11784 PSU, DO : 4.71477 mg/l [20:25:11] Steph - are you sure it was a basketstar and not just an ophiuroid? Members of ophiuroid family Ophiactidae can split. If a basketstar, do you know the species? [20:26:15] I dont know the species... 100% sure its a basket star... youll have to ask John about the name... he told me. i didnt see it after it left the ship [20:26:18] Thanks Charles [20:28:04] I will ask him. That swimming crinoid might have been Zenometra columnaris, but not sure. [20:29:29] LAT : 29.860084 , LON : -79.454951 , DEPTH : 764.5344 m, TEMP : 8.5746 C, SAL : 35.11701 PSU, DO : 4.72675 mg/l [20:29:46] Just chiming in without benefit of audio or video (I just have the chat open now), but if it helps sort some confusion... I've noticed some folks are now using the term "basketstar" in a very broad context to include the asteroschematid/euryalid brittle stars we see associated with several octocorals. I prefer to use basketstar only for those with branching arms. [20:29:53] to avoid such confusion [20:32:15] @Scott did you read previous comment above? have you ever collected one of small white octocoral (Plexaurid or Eunicella or something?) which abundant here? [20:32:47] Agree, Scott. I use "snake star" for the Euryalida with unbranched arms. [20:33:54] @Asako: I think perhaps we collected one on Dive 1...? Kim/Steph will have to remind me as I'm too pre-occupied with work to recall. [20:34:29] LAT : 29.860152 , LON : -79.455059 , DEPTH : 764.6269 m, TEMP : 8.57629 C, SAL : 35.11772 PSU, DO : 4.71628 mg/l [20:35:04] @Scott Stephanie said that she havent and mentioned that you may have... [20:35:49] antropocene [20:36:36] @Scott have you collected them on your own?/non-okeanos realted? [20:36:58] No - have not collected these in my own research. [20:37:34] I'd have to do a bit of research to see if we collected one on a previous SE USA OkEx expedition [20:38:12] This is not a primnoid. This is the white fan I think Asako is asking about...? [20:38:36] Back side of a blue sponge? [20:38:44] a shell? Cirripedia? [20:38:47] growing on a stalk [20:39:08] yes, I think so. I'm very interesting for the white one... any chance to collect one of them. they are so abundant, everywhere. [20:39:09] I dont think we grabbed one of those on day 1. I honestly cant remember which coral we are talking about anymore... ive seen like a million LOL. But we do post all the colletions someplace... if you wanna look. [20:39:11] No I do not think it is a sponge but it could be a very thin Hymedesmia [20:39:30] LAT : 29.860158 , LON : -79.455311 , DEPTH : 766.5714 m, TEMP : 8.57481 C, SAL : 35.11758 PSU, DO : 4.717 mg/l [20:40:08] The white one I am referring to is this sparse brancher that was in front of the sponge we just imaged [20:40:22] Ah ok [20:40:26] It appears to have most polyps on one face of the colony [20:40:32] i dont think we grabbed that ine [20:40:37] *one [20:40:43] I think Kim guessed it was a primnoid [20:40:56] looking at the dive summary from Dive 01 that is accurate [20:41:23] @Mike: too many lines here! What is accurate? [20:42:00] Pentametrocrinus atlanticus - the only known 5-armed feather star in the western Atlantic. [20:42:31] Also, one of the very few crinoids known from both eastern and western Atlantic. [20:44:09] mariadiaz leaves the room [20:44:30] LAT : 29.859885 , LON : -79.455181 , DEPTH : 766.1596 m, TEMP : 8.57189 C, SAL : 35.11738 PSU, DO : 4.71562 mg/l [20:45:20] Interesting lee pattern of depsosition behind the sponge. [20:46:23] deposition [20:46:51] The sponge forms a nice baffle in the current. [20:48:28] These forams on the sponge appear to be the ones that create a framework of sponge spicules and assemble a central mass from planktonic foram tests. [20:49:07] Abundant thecosome (pteropod) tests - planktonic gastropod shells. [20:49:30] LAT : 29.859983 , LON : -79.455456 , DEPTH : 766.7348 m, TEMP : 8.57614 C, SAL : 35.11655 PSU, DO : 4.73212 mg/l [20:49:55] @Scott, from Asako and Steph's conversation, we did not collect one of these white fan asako is talking about on dive one [20:50:17] By "baffle" I meant the sponge deflects flow and typically slows down on back side so particles settle. [20:50:44] @Mike: copy that. Thanks. [20:51:07] We have not collected it. Do you want to collect it? [20:51:12] Then perhaps it is worth a collection if you see it in the final few minutes in a convenient spot. [20:51:27] the primnoid we saw? [20:51:32] The branching structure of the foram is glued together sponge spicules. [20:51:34] @Mike thank you. [20:51:36] let me know if oyu see it again [20:51:47] Not the primnoid, but perhpas what you are calling a primnoid. [20:51:55] The bottle-shaped pteropod (thecosome) is Cuvierina. [20:52:08] But, yes, the sparse white brancher with polyps restricted to one face. [20:52:18] @mariadiaz because no one know what it is, and there are abundant at that time [20:52:20] oh shout out if you see it again [20:54:31] LAT : 29.859987 , LON : -79.455657 , DEPTH : 767.4765 m, TEMP : 8.56938 C, SAL : 35.11704 PSU, DO : 4.71021 mg/l [20:55:31] Dive 4 - we heading heading to a newly mapped mound field north of here [20:56:12] Feeding on a stylasterine? [20:56:35] Back for a few minutes. Fishes seen recently: Greeneye, Genus Chlorophthalmus, correctly IDed. Other small deep-bodied blotched fish in nice close up = the Acropomatidae, Synagrops bellus. Hagfish with single gill opening = Myxine glutinosa, and yes the white spots are where the now buried and vestigal eyes would be. Small macrourid angled obliquely to substrate, black dorsal fin margin = Nezumia bairdii, an opportunistic predator of small mobile epibenthic inverts including amphipods, isopods, [20:58:09] THANKS! [20:59:31] LAT : 29.86004 , LON : -79.455883 , DEPTH : 767.753 m, TEMP : 8.56927 C, SAL : 35.1163 PSU, DO : 4.72407 mg/l [21:00:25] Unless it is of critical importance to you, I won't be on dive planning call to follow. [21:00:43] no youre fine. [21:00:48] Thanks. [21:00:52] A night dive upon this rubble substrate would be worthwhile. There is still enough ambient light at this depth to be used by organisms - like Nezumia, Synagrops, and Chlorophthalmus - all with very large eyes to collect dim light. I would predict that at night lots of epibenthic inverts, like Hyperiid amphipods emerge from the rubble matrix when their visual predators are at a disadvantage. Also, at night many midwater fishes would likely visit the rubble habitat to feed upon emergent mini-crustacea [21:00:59] "See" you tomorrow. [21:02:29] vertical silver fish in distance = a barracudina, family Paralepididae - a midwater fish that visits the benthic boundary zone [21:03:41] EX1907_DIVE03 ROV Ascending [21:04:06] scottfrance leaves the room [21:04:07] Thank you for today's dive!!
