I'm a graduate student at College of Charleston and I'll be annotating geology for the first half of today's dive - very excited to be a part of this! [14:10:07] welcome Zach! [14:10:34] ETA on bottom is 955 CT [14:20:45] okexnav leaves the room [14:25:15] okexnav leaves the room [14:25:45] scottfrance leaves the room [14:26:08] divaamon leaves the room [14:35:47] okexnav leaves the room [14:52:23] robertcarney leaves the room: Replaced by new connection [14:54:16] fernandoaragon leaves the room [14:58:50] Helle all. [14:59:34] Hi Asako! [14:59:40] Hi Scott! [14:59:43] What time is it there? [15:00:02] it will be 17 April within 1 min. [15:00:41] I am here with a group of students from Biol 111 and we are checking out the dive. I've told them we have scientists fro around the world participating. [15:04:07] Hi all [15:05:31] Hi Megan [15:05:38] @Scott: it is good for student to know that they are lucky to be in the better time zone. [15:09:11] @Scott, how many students do you have with you? I'm competing with Marathon Monday over here, but hoping students will show up [15:09:19] this is Heather Olins, btw [15:11:45] halosaur = salt lizard [15:12:13] thannks mike [15:18:25] anyone else getting music over the phone line? [15:19:03] Sounds like someones hold music is playing. [15:19:12] I can't hear the lead scientists [15:19:19] is that a Bythididae ? or am i way off? [15:20:34] they are talking now, can you hear them now ? [15:20:42] +All please mute your phones when not speaking we are hearing music or hold music through the telecon - thanks [15:22:53] thomasritter leaves the room [15:24:38] laurenjackson leaves the room [15:31:57] Can we get nav/bathy screen on Camera 3? [15:32:47] you can access that in the "navdata" chatroom [15:35:20] Still have the music on the line... [15:35:39] 100 m move complete [15:40:34] iscwatch2 leaves the room [15:40:43] Daniel - I can't hear you on the video... [15:40:53] I can hear Adam [15:44:09] could you hear me just now scott? [15:44:12] I don't see the lasers on [15:44:22] No Daiel, I could not. You were a whisper [15:44:34] shirleypomponi leaves the room [15:45:10] @ Dan can you type that shrimp name for me please? [15:45:21] Lasers? [15:45:55] Nematocarcinus sp. (likely N. ensifer) [15:47:21] Is the music gone from the phone line? [15:47:34] yes music gone [15:48:44] I wonder if it was my line... Never happened before, but that sounded like cajun music. I certainly didn't push any hold button. [15:49:05] danielwagner leaves the room [15:49:36] meganmcculler leaves the room [15:53:25] Isopod [15:53:40] Daniel - you are still inaudible on my feed. Adam is fine. [15:54:05] danielwagner leaves the room [15:54:10] meganmcculler leaves the room [15:55:01] are you listening on the phone or video stream? [15:55:07] That was not a pycnogonid. It was an isopod. [15:55:41] thanks, i will change it in sea scribe [15:55:45] thanks mike and scott. I did not get a good view of it. [15:56:10] Please add any observations in sea scribe also if you can, many thanks! [15:59:06] danielwagner leaves the room [15:59:38] iscwatch2 leaves the room [16:00:16] scottfrance leaves the room [16:01:09] Chris Mah says that sea star we say earlier is Nymphaster arenatus [16:01:37] thanks Megan! [16:02:52] Re: SeaScribe - I was in the middle of a live interaction so couldn't also be logging, but will try to keep up now. [16:04:06] danielwagner leaves the room [16:04:12] Thank you Scott [16:08:45] meganmcculler leaves the room [16:09:07] danielwagner leaves the room [16:11:17] iscwatch2 leaves the room [16:13:54] fernandoaragon leaves the room [16:14:08] danielwagner leaves the room [16:16:33] meganmcculler leaves the room [16:18:03] 100 m move complete [16:18:13] iscwatch2 leaves the room [16:19:08] danielwagner leaves the room [16:20:03] It appears there may still be connectivity issues with the ship in the chatroom... [16:25:35] iscwatch2 leaves the room [16:31:11] You are almost due south of my office! [16:33:26] Perhaps a nice furrow to deposit eggs...? [16:33:32] That from a non-fish biologist! [16:34:18] iscwatch2 leaves the room [16:34:47] I wonder whether the fish just took up residence in the furrow or if that species is responsible for at least some of the furrows we have been speculating are from beaked whales. [16:35:43] bcclass1 leaves the room: Replaced by new connection [16:37:15] gotta go teach [16:37:21] michaelvecchione leaves the room [16:37:28] thanks mike [16:39:16] shirleypomponi leaves the room [16:40:26] iscwatch2 leaves the room [16:42:26] laurenjackson leaves the room [16:42:32] zachproux leaves the room [16:45:31] Nice ctenophore [16:46:01] nice close up! [16:46:29] meganmcculler leaves the room [16:46:57] iscwatch2 leaves the room [16:49:44] paullarson leaves the room [17:02:33] enriquesalgado leaves the room [17:04:39] Unfortunately Kody Kramer passed away April 11 http://www.ryanmortuary.com/obits/2018/kra80411.html [17:08:18] will be missed [17:08:31] This looks like good habitat for tripod fish... Where are they? [17:09:00] We saw them often on these sorts of sedimented ridges in the deep Bahamas [17:09:02] Hi All. I am at the ECC in Charleston at the Holling's Marine Lab. I will be recording CMECS geological observations in Sea Scribe from 1300-1700. I'm taking over for Zach Proux [17:09:27] Welcome aboard Robert. [17:11:29] Maybe a Bathypalaemonella...? [17:13:50] mikeford leaves the room [17:18:59] colleenpeters leaves the room [17:22:46] iscwatch2 leaves the room [17:23:05] Aha! Knew it would show up! [17:23:44] Scott: how about to predict something corals? [17:24:06] danielwagner leaves the room [17:25:05] Good idea! This looks like ideal habitat for sea pens. Where are they? [17:25:13] Will that work? [17:25:30] Re: Industry Interest. This block was leased 2004-2014 but is no longer under lease. [17:25:55] Actually, the bamboo coral Acanella should also grow in areas like this, rooted into the sediments. [17:27:50] hopefully it will work! [17:32:53] From our amplitude mapping, we don't see any hardground signatures. Sorry I didn't respond to this area sooner, but I've been at Kody's memorial service in Kansas [17:34:13] thanks bill [17:34:35] can we get laser sights? [17:35:51] robertcarney leaves the room [17:36:15] thank you! [17:38:32] Interesting radial track pattern in seds visible as ray swam... [17:49:32] I guess we'll have to add sponges to the "Mobile benthic inverts" menu on SeaScribe... ;-) [17:56:01] I like it - cnidarian on a hard sustrate and drifting sponge. Signs of better things to come? [17:56:32] And by "better" I mean from the sessile fauna perspective, so apologies to soft sediment fans. [17:57:07] your prediction partly works Scott! [18:02:22] I am not a fish person, is there an ecological reason why it keeps its tail up in the air like that? [18:02:28] "air" [18:04:24] I am not a fish person either, but I have seen several species orient head down. I think the idea is to be better able to detect benthic prey moving over or off the bottom, and to quickly grab them. [18:06:48] makes sense, thanks [18:14:47] Seaweed stranded on bottom [18:15:05] I was hopeful there before we zoomed in... [18:15:30] Sargassum covered in bryozoans :) [18:16:14] The question is whether those are bryozoans from the surface or deep! [18:17:01] @Scott probably the surface. Jellyella tuberculata is very common on Sargassum [18:21:06] stevenauscavitch leaves the room [18:29:09] danielwagner leaves the room [18:29:48] thomasritter leaves the room [18:31:41] meganmcculler leaves the room [18:35:07] meganmcculler leaves the room [18:35:54] larvacean [18:36:00] 100 m transit complete [18:36:47] @mega: is jellyella tuberculum a deep or shallow-water species? [18:37:25] She said it was a shallow ater taxon. [18:37:32] shallow water [18:37:44] thanks megan and scott! [18:38:11] Specifically she answered me (about whether it was surface or deep originating) "probably the surface. Jellyella tuberculata is very common on Sargassum" [18:38:32] thanks! [18:39:47] mini midwater there [18:40:40] fish head down - could be reacting to the lights of the ROV. we see this frequently at MBARI where the fish swim into the bottom. not a normal behavior [18:40:59] What about a pyrosome? [18:41:14] I would guess pyrosome based on the brief glimpse [18:41:17] hard to say [18:41:59] Took me a little while to remember by login password - saw what looked like a scaphopod shell earlier (white shell) coming out of the sediment [18:42:01] my guess is pyrosome as well [18:42:40] @George: is it possible you are referring to a pteropod shell? I've seen several of those. [18:43:38] @George: and I don't mean to be implying you don't know the difference between a scaphopod and a pteropod! [18:43:53] Looked too long for a pteropod, but I didn't get a good look [18:46:07] looks more like tar? [18:51:56] It doesn't look like tar extrusions like we've seen before, but maybe dropped from above - a ship? [18:52:50] nice parasitic copepod? or leech? [18:53:50] It is either an amphipod or isopod. Last view I had suggested isiopod, which is what I would expect as more common parasite. [18:53:59] *isopod [18:54:19] legs. isopod seems right [18:54:50] what was the genus of that fish, so I can add to SeaSketch? [18:55:02] nevermind [18:55:37] Dicrolene [18:56:59] http://www.marinespecies.org/deepsea/photogallery.php?album=3746&pic=129746 [18:57:26] beautiful ctenophore [18:58:02] extended tentacles [18:58:10] the light is diffraction NOT bioluminescence [18:58:22] meganmcculler leaves the room [18:58:35] tentacles delicate and nicely extended [18:58:48] yes! great shot [18:58:58] beautiful!! [18:59:45] completed another 100m transit [19:02:34] finally octocoral! [19:09:39] This guy's been waiting his entire life to look beautiful for our lights to illuminate him [19:13:13] I'm not certain, but there may have been a small squid in the wtare column just passed... [19:13:20] *water column [19:16:24] meganmcculler leaves the room [19:17:23] georgematsumoto leaves the room [19:18:44] Great 2017 read..SALT Tectonics Principles and practice Jackson and Hudec [19:20:02] thanks robert [19:32:15] Spectacular [19:34:20] we got highlight video :) [19:35:36] The discussions of the pilots overwhelm/interfere with the science discussions. It's very distracting. Can you control their volume [19:36:14] mattdornback leaves the room: Replaced by new connection [19:38:18] @Bill: you can control it by adjusting the left-right balance on your computer audio. [19:38:51] Science is on one channel, pilots the other. [19:38:54] @Daniel did you say we hit another 100m? [19:39:26] yup [19:41:10] thank you! [19:46:08] Ipnops murrayi [19:47:49] if we see another dark colored ctenophore, would you take some video? i believe that is an undescribed species. [19:48:48] thanks! [19:49:37] yeah, hit the brakes :) [19:49:47] Geez Mike! Can you request a bamboo coral for me! [19:50:08] thats nice. [19:50:27] Fantastic pigmentation [19:50:31] those tentillae are fantastric [19:50:46] nice movement. [19:50:58] I just sent shots of cer to Tina. [19:51:18] the details in the retraction are exccellent [19:51:25] colloblasts [19:51:29] sticky cells [19:51:38] really nice images there. [19:51:42] thank you for the time [19:52:12] meganmcculler leaves the room [19:52:36] no problem, we will keep looking [19:52:47] for more [19:54:11] danielwagner leaves the room [19:57:36] Tina mentioned there are only 2 spp Cerianthus reported from GoM. [20:02:48] carolynruppel leaves the room [20:03:51] paullarson leaves the room [20:04:09] Dying/dead ctenophore...? [20:04:28] no idea [20:05:49] It was either that or a larvacean house... [20:07:04] my guess would have been larvacean house based on the absence of combs, but the shape certainly looked like a ctenophore [20:07:43] missed it. iw as emailing people to log in latter to see the great footage of the dark cydippid [20:07:56] was, later. typing too fast [20:09:06] The overall shape suggested ctenophore to me, not larvacean house. [20:09:17] We just passed over another nice radial feeding trace. [20:09:48] cool. definitely will check that out later. [20:12:10] woohoo another ctenophore [20:13:09] cteno left [20:14:15] awesome, full day midwater dive that is. :) [20:15:45] larvacean [20:17:34] laser sights? [20:18:16] stevenauscavitch leaves the room [20:18:33] I feel like I should know what that trace was... [20:19:56] Another 100 m transit completed [20:19:59] The mystery mark that looks vaguely familiar may be an imprint. Tim Shanks tried digging and only found mud. Realtively common [20:22:10] Thanks Bob. Could be the curled legs of a crab piercing the mud. [20:23:50] thanks scott [20:27:49] does it look like that might be a gravid female? [20:31:05] If we wanted to add to the mystery of the deep, this sediment "smoke" is doing a good job! [20:32:11] could the crab be Chaceon ? [20:32:28] we saw some of those off Puerto Rico and in the Pacific last year as well [20:32:32] guess Chaceon fenneri [20:32:44] i don't think that was chaceon [20:32:46] Bathocyroe [20:33:16] see the four auricles [20:33:24] sometimes they collect falling particles [20:33:38] meganmcculler leaves the room [20:33:59] beautiful! what a way to end the dive! [20:34:25] End? Mike - there is a lot of water column to go through to get to the ship! [20:34:48] stevenauscavitch leaves the room [20:34:51] Oh yeah, you're right. just getting started [20:34:58] chaceok quinquedens? [20:36:46] on that lasst cteno...the comb rows looked like bathocyroe, but the tight looking lobes looked like thalassocalyce from Monterey [20:37:19] we will look at that sequence again. there are many undescribed lobates at the moment, so the field is busy sorting them all out [20:37:39] more exploration means more observations to fuel our discussions [20:38:20] yes!!! best dive ever [20:38:35] zoom in on body to see canals [20:38:45] super zoom [20:42:17] It looked like the tentacles were controlled independently... some retracted while others not. [20:42:55] or tentilla rather [20:43:18] @Paul: I agree. [20:44:22] rachelbassett leaves the room [20:44:30] robertmcguinn leaves the room [20:45:11] Can you repeat: post-dive call at 4 pm? [20:45:21] robertcarney leaves the room [20:45:47] katerose leaves the room [20:46:20] yes, 4 CT [20:47:40] meganmcculler leaves the room [20:48:13] Thank you very much for the today's dive! see you tomorrow! [20:48:19] asakomatsumoto leaves the room [20:48:41] thank you for all the great imagery of the ctenophores. really exciting.
