[14:05:16] Is it already over? [14:06:39] Yes, just finished [14:06:53] Wow! That must have been fast! I called in at 0902 [14:06:58] nothing much to report. ETA on bottom 10 CT [14:07:11] diving across steep slope from 2250-1700 m [14:07:25] OK. Will hang up until then. [14:07:44] this is similar to dive 6 on EX1711 (which was 25 km east of this location) [14:15:04] adamskarke leaves the room [14:16:06] robertcarney leaves the room: Replaced by new connection [14:18:36] I think nav meant staring at the "beautiful" blue water column... ;-) [14:19:07] robertcarney leaves the room [14:21:02] robertcarney leaves the room [14:25:42] Colleen on duty [14:28:15] daniel, how long to the bottom? [14:30:19] we should be on the bottom around 10 [14:36:09] nolanbarrett leaves the room [14:36:33] audio is not coming through on camera 2 [14:37:30] we can hear you on EVNT on RTS but not through the live feed [14:40:06] We are doing a live event right now [14:40:32] you should be able to hear the audio on camera 2 when the live event is over [14:41:27] yeah is there a reason why you dont have the EVNT on camera 2? [14:41:34] is it a private event? [14:43:02] it is a private event with school children, apologies for the inconvenience [14:43:58] They set up a different camera to talk with the scientist for this event that is why it's not on a normal feed [14:48:33] we will do the dive intro in ~~10 min [14:48:48] yeah, the camera feed is still broadcast to the internet, so there are talking heads with no audio [14:49:22] was just curious! [15:03:09] on bottom [15:03:46] EX1803_DIVE09 ROV on Bottom [15:05:34] adamskarke leaves the room [15:06:34] scottfrance leaves the room [15:11:49] no audio any video feed [15:12:49] I can hear your audio [15:12:54] yes audio now [15:13:01] Got the audio [15:13:27] mysid, I think [15:13:44] Loud and clear now [15:15:36] cerataspis [15:16:08] adamskarke leaves the room [15:17:50] acanthonus armatus [15:24:53] feeding behavior termed "snarfling"...as in snarfing down :) [15:29:35] Lots of spoon worm scars in the sediment here. [15:29:48] robertcarney leaves the room: Replaced by new connection [15:32:12] Ilyophis brunneus [15:39:18] water hyacinth [15:43:30] Aldrovandia gracilois [15:49:21] cirrate = finned octopods (dumbo) [15:49:44] The fins are on the sides of the body, not the head. [15:53:17] some would argue that sponge reefs still exist at high lats [15:54:55] robertcarney leaves the room [15:55:13] nolanbarrett leaves the room [15:57:21] primnoid [15:57:43] polyps in verticils [15:58:10] 2 polyps per verticil [15:59:29] I do not know if any unbranched species reported from GoM [15:59:32] Candidella? [16:00:14] just have a few minutes to join today. Looked back to find very nice video of Acanthonus armatus and Ilyophis brunneus. Heard comment on eel-like body form being common among fishes in deep water. True and functional. Eel-like and rattail-like body form with a long attenuate tail and tiny or obsolete caudal fin corresponds with anguillaform locomotion - slow undulation of the whole elongate body. This is very efficient at slow speeds. When a quick escape is needed, the body is thrown into a very exaggerated whipping motion, effective but inefficient. Normal slow undulation corresponds with energy conservation is a food-limited environment. [16:01:15] zoom at brambles? [16:02:59] the only Candidella reported from GoM is C. imbricata and it is branched.... [16:03:54] thanks tina [16:05:44] same primnoid [16:06:18] Perhaps of interest: Acanthonus armatus has a tiny brain with a capacious skull filled with light ion fluid to provide bouyancy, in combination with gelatinous body tissues with very reduced musculature. The Acanthonus brain is the smallest relative to body size of any fish species. [16:07:02] Its not unreasonable that there could be more species of Candidella from the Caribbean and Gulf of Mexico. Candidella gigantea (or something closely resembling it) was reported from the Bahamas and G. Antilles [16:08:22] from material or from photos? [16:09:06] I mean may be it is worth to collect? [16:09:18] The cirrate octopod was probably genus Cirrothauma (see http://tolweb.org/Cirrothauma/20095). [16:09:45] Photos and material. [16:11:10] I think any unbranching primnoids are definitely worthwhile to collect, if we come along one at the right moment. [16:12:33] it was at least three colonies sofar... so it is unlikely uncommon here [16:14:29] it IS primnoid [16:14:44] collection? [16:14:57] potential collection, if possibl [16:15:05] at least it is common [16:15:36] we can consider it as a dominant species and we are not sure what is it [16:16:36] erineaston leaves the room [16:17:49] if forked colony a bit downslope is the same or different? [16:19:24] DOesn't look forked to me. Maybe I can't see it. Down and to the left of the sample target? [16:19:38] no, it is out of view now [16:20:23] should I call this specimen Primnoidae ? [16:20:47] upper colony will be nice, it is a little bit bigger [16:21:18] Primnoidae is OK [16:21:31] thanks! [16:22:40] This is great. If it is candidella gigantea it will be a new records for the GOM and one of the few vouchers from the western atlantic. [16:22:50] Thank you pilots too, well done. [16:23:07] ... not in the box yet [16:25:33] kensulak leaves the room [16:26:35] it was very neat and fast collection indeed [16:28:50] amybowman leaves the room [16:28:50] williamshedd leaves the room [16:32:56] adamskarke leaves the room [16:37:58] amybowman leaves the room [16:45:23] adamskarke leaves the room [16:50:40] echiuran? [16:54:14] scaphopod [16:54:41] @mike, it looked as echiurian for me as well [17:00:59] ipnops [17:01:39] a fish experiment? [17:02:27] they have bony membranes over degenerate eyes [17:02:39] Looks like an echiuran feeding trace to the left of the Ipnops [17:03:17] cool! [17:04:48] nolanbarrett leaves the room [17:05:01] I've rarely been so excited to have the lights turned off... [17:05:27] I see no glow... [17:06:10] maybe they fluoresce instead [17:06:21] bno glow here as well [17:06:35] I'm expecting to see a lurking beast when the lights come on... [17:06:44] It will dart away. [17:07:14] very coopretative fish... [17:07:33] nice and cooperative [17:07:57] is it alive? [17:14:34] assfish [17:16:17] Aldrovandia [17:17:13] maybe gracilis….but i am too conservative with species names on halosaurs. [17:17:21] Coryphaenoides [17:18:17] parasite? [17:18:30] rudis? [17:18:41] with parasite [17:19:53] yea maybe rudis [17:25:04] adamskarke leaves the room [17:27:13] Aldrovandia [17:27:27] another whip [17:29:17] adamskarke leaves the room [17:35:55] Acanella [17:36:02] That has got my attention! [17:36:25] reminds me of a bamboo we saw during the okeanos puerto rico ex [17:36:36] Could be an Acanella with relatively few branches... [17:36:45] sampling? [17:37:01] We collected an Acanella from this area last December. [17:37:10] on Dive 5 [17:37:26] same morpho? [17:37:50] Looks pretty similar, but this lighting is not as good. [17:38:04] In bright light there is clear red on the polyps [17:38:16] Red mouth, pink pharynx [17:39:19] But a BIG difference is the one we collected last year was rooted in sediment [17:39:24] thanks scott [17:39:48] This one was not, so I guess it would be very instructive to know if it is the same species on both sediment and hard substrate. [17:39:58] Stichopathes? [17:40:10] Note: last year we collected the colony with the root intact. [17:40:41] adamskarke leaves the room [17:52:24] adamskarke leaves the room [18:00:14] jimmasterson leaves the room [18:08:43] adamskarke leaves the room [18:11:29] @Daniel: my previous point was that perhaps this "Acanella" is not the same as the one we collected last year. These clearly have holdfasts attached to rock; the one last year was rooted in sediments. They could be the same, but we won't know without a collection. [18:11:51] thanks scott [18:12:01] should we try to collect? [18:12:09] I am OK for collection [18:12:31] I will leave that to the majority, but I am saying it is back on the table for consideration to collect. [18:12:40] i think we will see it again [18:12:52] thanks scott [18:13:09] everyone else ok with collecting the acanella if we see it again? [18:13:27] Acanella are known to live/grow on both hard and soft substrates. I think single species are able to adapt their "attachment" to be holdfast or rootlet. [18:14:01] So a priori I suspect this is likely the same thing as was in the sediment, but I can't guarantee it (I know you aren't expecting any guarantees!) [18:14:24] here it is [18:15:45] what is that white colony belo goniasterid? [18:15:52] There are 2 Acanella known from out here: the widespread Acanella arbuscula (which now includes the former A. eburnea) and the recently described A. aurelia [18:18:04] if it is ok with everyone we will hold off on acanella collection until covering a bit more ground. [18:21:42] Yup. [18:21:53] Isopod [18:22:17] By "yup" I mean "No problem holding off on Acanella collection." [18:24:41] Munidopsis [18:24:48] it is pink.Munudopsis is usually white? [18:27:44] anemony for me [18:27:53] ceriantharia [18:28:00] Looks like a relicanthus? [18:28:02] looks like Relicanthus in fact [18:28:09] Looks to me like a Relicanthus [18:28:15] Agree with relicanthus [18:28:31] Note the long, long tentacles [18:28:56] if Relicanthus reported from Atlantic? [18:29:08] An unusal distant relative of the anemones, but not considered to be a true anemone. [18:29:17] At least based on genetics. [18:29:46] hm, even cerianthid can be considered anemone... with tube [18:30:28] Yeah, Relicanthus is supposed to be a separate order. [18:30:38] More closely related to zoanthids and atipatharians than to actiniarians [18:31:05] does it occur in Atlantic? [18:31:13] @Tina: I mean based on phylogenetic classiifcation. In terms of gross morphology I agree it is essentially an anemone. [18:31:45] @scott, I kow about genetics) [18:31:54] know) [18:32:13] @Tina: I know you know! [18:32:22] @Tina: I don't recall its distribution. [18:33:38] @scott, it was described from EPR, we had it throughout Pacific [18:33:46] Could be new record for the Atlantic... [18:33:51] @Tina: yup. [18:34:11] I cant remeber it from Atlantic [18:36:23] juv crinoid [18:40:08] @Daneil can you spell that genus [18:40:21] Pythonaster [18:40:32] thanks! [18:42:04] How do the videos look today? Has there been any tearing or pixelation? [18:43:12] @Josh: I have not noticed any pixelation, but I haven't been able to follow as closely today as I typically do. [18:43:22] gigantism? [18:43:28] a little pixelation. not much. looking good. [18:43:57] @josh, I had problem with audio at videofeed for beginning of the dive [18:45:15] sorry, have to go, will try to catch the end of the dive [18:45:43] Thanks everyone! [18:45:53] good luck with attached Acanella sampling [18:45:53] joshuacarlson leaves the room [18:46:10] Bye Tina [18:46:33] bamboo [18:47:09] adamskarke leaves the room [18:47:15] tinamolodtsova leaves the room [18:47:19] If it was an unbranched young Acanella, there should still be a node at the base. [18:47:32] That is how you can distinguish it from other possibilities. [18:48:10] Is this a Polymastus like sponge in the foreground? [18:48:18] Have you seen those alrteady today? [18:48:28] yes scott [18:49:14] You don't need to stop now to collect Acanella for me. [18:49:27] I understand if you want to keep moving. [18:51:51] Looks somewhat different but I'm at a loss. [18:52:08] oh looks like two sets of tentacles [18:52:15] I think I see inner ring of tentacles [18:52:16] cerianthid... [18:53:12] Interesting - didn't see the tube, but sure looked like a cerianthid [18:53:31] @Scott I didn't see tube either [18:55:58] erineaston leaves the room [18:58:07] Deimatidae [18:58:39] adamskarke leaves the room [18:59:45] joshuacarlson leaves the room [19:04:39] ott, you mind typing in the tentative ID [19:04:55] scott i mean [19:06:59] Keratoisis "kerJ3a". As far as I can tell, this would be the first record in the GoMex. [19:07:10] adamskarke leaves the room [19:07:35] thanks scott [19:08:16] We have previously sampled it from the Bahama Escarpment, slope of Abaco Island, and Nashville Seamount, [19:09:42] Agree with splendens. [19:10:03] another coral at 2 o clock [19:13:25] Corallium? [19:14:43] Corallium niobe [19:15:47] Daniel - I hear you on vidoe but not on the phone line... [19:15:56] Sibogagorgia cauliflora [19:16:17] This Iridogorgia looked branched at the base. Can you verify? [19:16:56] The shrimp is potentially egg-bearing? Purple clusters under the abdomen [19:17:24] Mary was just giving you an ID. I'm pretty sure you have been disconnected from phone line. [19:17:37] @scott: troubleshooting the phone line now [19:17:43] Yes - those are eggs held on the pleopod [19:17:47] @Adam: copy [19:18:09] Stephanauge sp. is a possibility for the anemone. They often grip corals like that. [19:19:16] Narella [19:19:53] Clavularia rudis [19:20:11] Paramuricea [19:20:20] Fiesta! [19:20:29] Niice fiesta! [19:20:34] Octocoral fiesta? Is that like a coral garden? We need the definition of that... ;) [19:20:48] Trachythela rudis [19:21:55] I don't think it is that recent - just the databases are behind, perhaps. [19:23:31] I hear you, Scott [19:27:42] I don't hear anything on the live stream, though [19:27:52] Cerianthid maybe, looked like 2 tentacle rings [19:28:02] adamskarke leaves the room [19:28:47] @paul I annotated it as a Cerianthid [19:30:54] yes, I can hear now [19:32:18] Isidid with polyps retracted [19:33:49] Possible Eknomisis based on retracted polyp shape [19:36:28] Brachiopod? [19:38:13] adamskarke leaves the room [19:43:30] adamskarke leaves the room [19:55:07] michaelvecchione leaves the room [19:55:53] Definitely less active in their feeding than shallow water barnacles [19:56:08] Sit and wait.. [19:59:17] primnois [20:00:15] This is Candidella imbricata [20:02:11] stevenauscavitch leaves the room [20:02:11] I think we missed the coral I was referring to. It is slightly downslope to left, I believe. [20:05:42] adamskarke leaves the room [20:15:22] enriquesalgado leaves the room [20:17:41] adamskarke leaves the room [20:19:28] FYI: from the December 2017 GoMex expedition: https://oceanexplorer.noaa.gov/okeanos/explorations/ex1711/dailyupdates/media/dec5-1.html [20:19:47] Excellent! [20:20:13] Almost the same area, so a consistent observation. [20:22:48] Diplacanthopoma sp.? [20:27:34] Would it be possible to move post-dive call 5 minutes earlier? 3:40? [20:27:58] Thx. I have to leave for a seminar at 4 pm [20:29:01] williamshedd leaves the room [20:29:05] Great dive everyone!
