[01:39:49] nickpawlenko leaves the room [12:51:44] robertcarney leaves the room [13:34:26] Nice looking transect. Could have lots of interesting stuff to see. [13:34:56] I'm not currently on the phone. [13:37:35] ship---great maps this morning...nice visualization [13:42:13] ETA on bottom 855 CT [13:49:33] scottfrance leaves the room [13:54:27] michaelvecchione leaves the room [14:03:35] Hello all [14:04:00] Hi Asako [14:04:06] Hi Tina! [14:08:10] Myctophidae? [14:13:26] hutchetfish. [14:13:34] sternoptychidae [14:13:40] and eel [14:19:51] what was the name of that fish please? [14:19:57] quick squid [14:21:28] megancromwell leaves the room [14:21:51] Here is the link for today's dive in seascribe https://divelog.oceannetworks.ca/Dive?diveId=1173 [14:25:47] it does not look like much hard substrate here.... [14:26:31] not yet tina, hopefully soon [14:29:28] danielwagner leaves the room [14:34:28] danielwagner leaves the room [14:39:03] danielwagner leaves the room [14:39:07] pteropod [14:41:09] Is there audio being broadcast with stream today? [14:41:31] Enrique I can hear it [14:41:39] I can hear audio. [14:41:49] thx [14:42:56] Ornithoteuthis antillarum [14:44:06] Bathytuethis? [14:44:35] Or maybe Mastigoteuthis, Mike? [14:45:58] Mastigoteuthis sp., thanks for the confirmation Mike! [14:50:25] Holothurian [14:50:51] Squid in disguise? [14:51:07] squid indeed [14:51:30] lovely [14:51:32] wow [14:51:36] Or cuttlefish. [14:51:43] where mike&) [14:51:48] Same difference. Get me Mike! [14:51:50] stick with it, please! [14:51:51] contortion squid [14:52:05] That is so cool! [14:52:07] Not cuttlefish- none in GoM [14:52:22] @Heather: that is what I though, but this appeared so bulbous. [14:52:26] meganmcculler leaves the room [14:52:27] Another Mastigotuethis? Haven't seen this behavior.... [14:52:43] brooding eggs? [14:53:28] paullarson leaves the room [14:53:44] suckers, not hooks on arms... [14:54:15] extremely cool!! [14:55:16] Making itself look like a lobster from above. [14:55:39] it looks like flying soucer... [14:55:52] The tentacles have tissue folding over to cover the suckers [14:56:54] @Mike- looks more like Discoteuthis than the Cycloteuthis by the fin... Both are in Cycloteuthidae.... [14:56:59] meganmcculler leaves the room [14:57:14] it looks like a lot of mid-water animals here [14:58:29] same as yesterday [14:59:17] @Daniel: will you let us know when you hit the 100 m marks? Thanks! [14:59:24] meganmcculler leaves the room [14:59:55] Ornithoteuthis antillarum [15:00:25] yup, the navigator working on 100 m marks [15:00:39] Happy to help! [15:02:44] meganmcculler leaves the room [15:05:05] 100 m transit complete [15:05:37] thanks! [15:06:25] The blind lobster... [15:06:32] Forgetting its name right now [15:07:15] Appear to be common inhabitants - perhaps constructors - of these burrows. [15:07:24] Acanthacaris caeca [15:08:45] Don Libatore used to be quite good at catching these lobsters [15:09:15] jimmasterson leaves the room [15:11:15] Lobster burrow indicates sediment at least 30cm deep...no hardground near seafloor. [15:12:43] heatherjudkins leaves the room [15:13:20] chloraphalmidae? [15:13:24] green eye?? [15:14:14] Chlorophthalmidae spelled correctly [15:17:36] Dang, those pleopods. [15:17:39] Super long pleopods - a good swimmer! [15:17:44] Cerataspis sp. [15:18:06] michaelvecchione leaves the room [15:26:27] jimmasterson leaves the room [15:26:33] good swimer [15:30:05] danielwagner leaves the room [15:30:38] danielwagner leaves the room [15:36:04] Gonostoma [15:36:44] Mandacus maderensis [15:42:50] amphipod [15:44:22] Giant was isopoda [15:44:29] danielwagner leaves the room [15:46:59] Another 100 m move complete [15:48:24] EX, can you please call back [15:49:13] Can we get "regular" feed back on camera 3 so I can see the nav map? [15:49:35] Or are you prepping for an interaction? [15:49:48] There it is - thanks. [15:49:52] we are prepping for an interaction [15:52:11] @Lauren: copy that. [15:52:24] I'm done with nav screen and camera 3. [15:55:04] They're here, but we have phone volume down while Sharon describes what they're seeing. [15:59:11] We are having some feed issues (fyi) [15:59:32] video or audio? [15:59:37] Video [15:59:45] Are you guys ready for interaction? [16:00:07] we are doing check now- did you hear them? [16:00:08] I am hearing a bit of break-up on the phone line and some interruptions on the video (but not much) [16:00:39] Let me turn volume up [16:01:13] Awesome. Thanks guys. [16:03:17] thomasritter leaves the room [16:03:35] Empty larvacean house [16:04:59] Another sponge...? [16:05:18] With zoanthids on the stalk this time [16:06:24] is this sponge well known species? [16:06:57] Scale worm at the base? [16:07:42] @Asako: I've certainly seen this morph of glass sponge commonly - even to the zoanthids on the stalk detail [16:07:59] Thank you Scott! [16:08:26] Hyalonema? sp [16:13:36] maurolicus sp [16:14:03] sorry, this is Lauren i typed wrong one manducus sp [16:15:50] This looks a bit different... A juvenile? [16:16:10] Tiny sponge next to the nose [16:18:08] heatherjudkins leaves the room [16:21:14] Is that another Gonostoma? [16:21:41] Oops, I should stick to what I know- inverts :) [16:26:04] heatherjudkins leaves the room [16:27:11] hydromesuae [16:27:32] Very hard to preserve too. Formalin and ethanol will 'melt' ctenophores [16:29:35] @Dan: Periphylla is a true jellyfish, so scyphomedusae [16:30:02] thanks scott [16:34:19] completed another 100 m move [16:34:43] rachelbassett leaves the room [16:36:48] nav data stopped... [16:42:59] danielwagner leaves the room [16:43:47] Salp? [16:43:55] no siphonophr [16:47:14] Hi All, I'm joining from the Holling's Marine Lab ECC in Charleston, SC. I'll be doing CMECS substrate observations, taking over for Rachel Bassett, from 1300-1700 EDT. [16:52:46] nav data stopped about 25 min. could you check please? [16:56:31] I just noticed something I haven't seen (or recognized) before: the lobate ctenophore used its lobes in the same way as a jellyfish uses its subumbrella - to provide some jet propulsion to move quickly. I hadn't realized ctenophores could do that! [17:00:00] @Scott Me either. I thought it was a jelly at first glance [17:07:04] megancromwell leaves the room [17:07:10] duck-billed eel...? [17:08:14] @scott ctenophores manipulate water in a number of ways. The lobates can even use jet propulsion as well as flapping propulsion in addition to the movement you saw [17:09:06] that's what came to my mind too Nettastomatidae ? [17:09:21] This is what it reminded me of: https://oceanexplorer.noaa.gov/okeanos/explorations/ex1504/logs/sept1/sept1.html [17:11:31] @George: thanks - I definitely saw the jet propulsion (about 30 sec before we reacquired the specimen for the beuaty shots) [17:14:23] Is anyone else hearing the live stream coming back over the phone line? [17:14:25] A hake, maybe...? [17:14:47] @Amy: yes, I think that is Mary's line open with her video audio playing in the background. [17:15:17] williammowitt leaves the room [17:15:37] Merluccius albidus [17:16:08] yes, commonly known as hake [17:16:29] Hey, maybe I'm actually learning some of the fish! :-) [17:17:21] epigonidae [17:18:30] amandademopoulos leaves the room [17:20:00] enriquesalgado leaves the room [17:25:37] Baby burrow... [17:28:34] heatherjudkins leaves the room [17:31:14] @mary what was the scientific name of the squat lobster please ? [17:31:20] If we don't have the suction sampler, it may be a difficult and time consuming collection, but otherwise I am not opposed. [17:32:53] Munidopsis spinosa - from Mary [17:39:22] Latest WORMS says new name is Galacantha spinosa....aha the joys of nomenclature [17:43:26] Thanks all! [17:52:47] oneirophanta like? [17:53:23] Deimatidae [17:53:32] thanks! [17:54:47] jimmasterson leaves the room [17:56:16] @Scott - that's the way I explained it while working as a naturalist! [17:57:11] holothuroids are vermiform echinoderms which have 2ndary symmetry [17:57:29] bilateral symmetry [17:57:38] fernandoaragon leaves the room [17:57:41] heatherjudkins leaves the room [17:59:02] camera 1 lost [17:59:07] Same here [17:59:19] same [17:59:28] danielwagner leaves the room [17:59:28] same [17:59:39] I did too, it is frozen [17:59:45] cameras 2 and 3 still OK...audio off as well? [18:00:01] I had audio on 2 and 3 [18:00:14] I think they simply are not saying anything right now - at least on the OkEx loine. [18:00:30] It is out at ISC as well. We are contacting Okeanos [18:00:45] frozen.. [18:01:01] Camera 2 and Camera 3 fully functional with audio, but nothing on Camera 1 [18:01:22] audio fine w/ camera 2 camera 1 still out [18:01:32] Stream 2 is out here as well [18:01:51] and stream 3 [18:01:55] Camera 3 just lost [18:01:55] Troubleshooting is going on and should be resolved soon. [18:01:56] the team is working on it right now, stand by please [18:02:00] yes 2 just went [18:03:35] Camera 1 back up [18:03:57] yes [18:04:00] Camera 1 fine now [18:04:13] nolanbarrett leaves the room: Replaced by new connection [18:08:43] zoom on rubble [18:14:05] williammowitt leaves the room [18:19:02] carolynruppel leaves the room [18:20:02] did we cross another 100m? [18:20:24] last 100m time stamp was 1134 ship time [18:21:05] Looks like Galacantha spinosa is a 2009 revision...lots of work on global galatheiids during Census Marine Life [18:30:26] erineaston leaves the room [18:32:44] anemone to the right though. [18:33:01] monofilament [18:34:57] nolanbarrett leaves the room [18:35:29] shale tectonics too...........http://wiki.aapg.org/Shale_tectonics [18:38:42] can you spell that sponge name please? [18:39:30] Could the bigger sponge be a Geodiidae? [18:39:42] POlychaete in sponge... [18:40:14] Carolyn is absolutely right - those are not carbonates. The seismic data show the bedding has been uplifted and exposed. It is very well indurated [18:42:54] The high amplitude I see on the data is probably not seepage but exposed indurated rock. Can you pick one up? [18:43:57] Do you have time to sample one? [18:47:01] @williamshedd, would you like the lighter outcropping rock or the darker rock that we speculated was asphalt? [18:56:41] Yes it's Pyrosoma atlanticum [18:56:48] Pyrosome or Candelabrum hydroid...? [18:56:56] Thanks Mark. [18:57:11] Are they often wedged in the bottom like that? [18:58:39] Most of our daytime observations of Pyrosoma atlanticum are at around 700-800m. So given the bottom depth here, it's possible it was descending and got trapped on the shallower bottom. [19:03:42] tinamolodtsova leaves the room [19:08:24] paullarson leaves the room [19:09:09] brittle [19:19:22] Lophiodes beroe [19:20:49] thomasritter leaves the room [19:24:04] scottfrance leaves the room [19:25:07] caitlinruby leaves the room [19:25:35] Its an echinoderm sweep! [19:27:03] heatherjudkins leaves the room [19:29:02] adamskarke leaves the room [19:34:19] @williamshedd: requested sample complete. Sample number: D2_DIVE04_SPEC01GEO [19:39:13] A sample of the small black rocks if possible? I was out of pocket this morning and missed info on the seep. Was this found with the EM302 water column mapping? [19:40:08] Sample? [19:40:26] roger that will [19:40:50] we will keep our eye open for a black rock [19:41:03] let us know if you see something [19:42:04] crater-like depression? [19:44:28] Though hard and suitable substrate for corals, we haven't seen much living on the rocks.. Interesting? [19:45:33] adamskarke leaves the room [19:57:52] have not seen GoM hardgrounds w/ so many lobsters [19:57:58] It appears the rock is hard enough to give me hard amplitude response on the seismic, but most of it is not related to seepage. We'll have to rethink our anomaly classifications. [20:00:42] By the way, though I didn't hear it since I was out of the office, thank you for dedicating this dive to Kody. He would appreciate it very much. [20:01:46] Maybe hard, but not stable [20:05:48] mikeford leaves the room [20:06:52] Yesterday's lack of seeps, hardgrounds along with a lack of seep related seismic anomalies is groundtruthing our mapping [20:07:59] @williamshed: We can sample a black rock for you here [20:09:03] Yes - the blacker the better [20:10:08] @williamshed The on one screen now? [20:10:46] I'm not sure either - they look more very dark grey [20:11:05] Would you like a sample of one of theses? [20:11:56] It looks like it may be off the ledge with about 30° dip above [20:14:25] robertmcguinn leaves the room [20:18:29] Thank you. Please make sure Carolyn gets a piece, Bob Carney, and myself, and whoever else is interested [20:20:00] Chaunax suttkusi [20:22:15] adamskarke leaves the room [20:23:00] @Bill: the rocks are sent to a repository at Oregon State, from which samples can be requested. [20:24:57] 8 arms [20:30:40] nolanbarrett leaves the room [20:34:22] Thanks for the anemone zooms [20:34:31] danielwagner leaves the room [20:36:13] Fly trap-shaped anemones can be in other families too - actinoscyphidae, hormathiidae, for two. [20:37:17] Actinoscyphiidae (for correct spelling) [20:37:34] roger that paul. That was not a venus fly trap though (my mistake) [20:37:46] I believe this was in the family Actinostolidae [20:39:27] Yeah, the big ones looked kind of 4-lobed [20:39:31] danielwagner leaves the room [20:40:35] can you zoom on the white coral below the anemone? [20:40:36] Hormathiidae [20:41:05] sorry amanda, did not see it [20:41:20] i think it was branching [20:42:24] Brisindidae [20:43:04] @daniel, prob worth double checking/replaying the video [20:43:41] Amana agree..looked branched [20:44:16] it actually looked like lophelia [20:44:32] danielwagner leaves the room [20:44:39] yes [20:45:17] thanks bob :) [20:45:36] I totally missed it... [20:45:42] we will check amanda [20:46:10] sounds good [20:48:40] paullarson leaves the room [20:51:57] adamskarke leaves the room [20:53:31] yippee [20:54:56] nice job out there! [20:58:42] jonathanjackson leaves the room [20:59:29] fernandoaragon leaves the room [21:00:04] chitin [21:00:35] robertcarney leaves the room [21:05:00] williamshedd leaves the room [21:06:04] amandademopoulos leaves the room [21:06:39] I missed if you said something about post-dive call... [21:07:13] call at 415 CT [21:09:09] jimmasterson leaves the room [21:19:19] scottfrance leaves the room [21:20:23] nolanbarrett leaves the room [21:31:19] georgematsumoto leaves the room [21:39:49] danielwagner leaves the room [21:41:54] adamskarke leaves the room [21:43:30] nolanbarrett leaves the room [21:56:30] amybowman leaves the room [22:13:11] briankennedy leaves the room
