[12:31:53] EX1806_DIVE02 ROV Launch [12:32:04] EX1806_DIVE02 ROV on Surface [12:32:22] iscwatch2 leaves the room [12:32:40] EX1806_DIVE02 ROV Descending [12:41:51] iscwatch2 leaves the room [12:46:07] scottharris leaves the room [13:27:51] scottfrance leaves the room [13:37:37] test [13:51:02] robertcarney leaves the room [13:53:21] mattdornback leaves the room [14:02:18] scottharris leaves the room [14:06:41] nickpawlenko leaves the room [14:10:38] Good morning, what is the ETA to seafloor? [14:11:13] Good morning Santiago! [14:12:39] mattdornback leaves the room [14:14:23] Good morning Tara! [14:16:13] Related to yesterday's dive, Chris Mah found a paper that talks about swimming ophiuroids. It was from 1991 by Hendler and Miller: https://books.google.com/books?hl=en&lr=&id=UKgfDsRffnkC&oi=fnd&pg=PA179&ots=GZDaDmu5wG&sig=hykCY-R0WvJhDQdbq5KEDFtCWsw#v=onepage&q&f=false [14:19:27] Hi everyone! We are really looking forward to this novel dive. Thanks for joining us. [14:20:47] nolanbarrett leaves the room [14:21:28] scottharris leaves the room: Replaced by new connection [14:21:44] My very first deep sea cruise was with Gordon Hendler. Brittle star feeding survey in the San Diego trough [14:24:12] We're about 15 minutes from reaching the bottom [14:26:46] @Leslie Good morning! Can't wait for today! Like yesterday, I'll be in and out of the lab, but I'll be able to check the chat most often. [14:27:40] Thanks Cheryl! [14:27:48] @Nolan - so glad you can join us. [14:30:59] Good morning. I helped on the Musician seamounts but back now. [14:33:08] @Tom Welcome back! [14:33:42] @nolan Thank you [14:34:29] Welcome Tom! [14:35:14] upasanaganguly leaves the room [14:35:15] @Hi Cheryl I hope I can help. Would love to see macroinverts. [14:35:28] Morning, everyone! I am with the University of South Florida St. Petersburg, work with Mike V. in the ceph world... may pop in and out until midwater dives later today [14:36:42] EX1806_DIVE02 ROV on Bottom [14:37:12] taraluke leaves the room [14:37:54] Hi Leslie and Cheryl, will you please give ROV NAV a gentle reminder to make 100m callouts. Excited for the dive! Good luck! [14:38:15] Hi everyone! I am with NOAA Office of Ocean Exploration and Research and I am managing our social media for the day. If we get anyone questions from the audience, I might be chatting them to you throughout the day and feel free to answer them live if there is downtime. Thanks. [14:38:27] Fish looks like Coryphaenoides sp. [14:39:29] Nav has been reminded to let us know when we've gone 100 m. Thanks Matt! [14:40:54] A rattail [14:41:50] thanks daniel! [14:41:58] Hello all [14:42:08] @Asako Hello! [14:42:21] Hi Nolan! [14:44:03] upasanaganguly leaves the room [14:44:45] looks like a sponge [14:44:57] Looked like possibly a sea pen [14:45:00] @Scott Harris and Jason Chaytor would either of you like to talk at some point about the Blake Diapir? [14:45:11] Angle was difficult though [14:47:12] danielwagner leaves the room [14:48:02] upasanaganguly leaves the room [14:49:04] Sargassum with bryozoans [14:49:39] and barnacles [14:50:23] Nematocarcinid [14:50:45] I am always late because I have to switch windows.Sorry [14:52:41] @Cheryl Tennative ID for yesterday was Phakellia sp. [14:53:03] I think this could be similar. Phakellia is a demosponge [14:53:32] Cavolinid test near sponge [14:55:20] nicolemorgan leaves the room [14:56:06] these barnacles are genus Glyptolasma [14:56:17] Nematocarcinus? [14:56:25] but why are they all closed up and the others were open? [14:58:17] Gastropod like Odostomia? [14:59:32] white sticks look like Cladorhyzids [15:00:18] georgematsumoto leaves the room [15:00:52] jimmasterson leaves the room [15:00:54] nope [15:00:57] fernandoaragon leaves the room [15:01:05] it is Bryozoan [15:01:13] that looks like a bryozoan [15:01:24] polyps looks like lophophors [15:01:43] Agree - this is a bryozoan [15:01:53] Talk about convergence of morphology! [15:03:07] all sesile animals look like each other if you have not enough zoom... [15:03:37] I guess the shrimp are nematocarcinids and not as important. In Hawaii one had that strange parasite. [15:04:09] why we have such...strange geology here [15:05:05] yeah that bryozoan, I was trying to make it fit the concept of primnoid! haha... [15:05:13] is it a scake worm at demosponge? [15:05:20] georgematsumoto leaves the room [15:05:45] "Cladorhizo-primno-bryozoan" [15:06:01] exactly! [15:06:12] hydroids [15:06:21] santiagoherrera leaves the room [15:06:26] small amphypod at stick [15:06:30] sorry, was in the lab, just catching up on the geology now [15:06:43] I see it. Could be Podercerid amphipod [15:06:52] yep [15:07:05] Podocerid [15:07:14] those sponges look like dumplings [15:07:21] The small upright fuzzy brown structures appear to be agglutinating foraminiferans, perhaps Astrorhizacea. [15:07:32] @Jason - any idea what the rocks are? very different from yesterday. lithified [15:07:40] nice scour moat around the rocks [15:07:50] @charles, some yes, but some were definitely hydrozoans [15:07:54] not yet, need a better look [15:08:07] I think there were both the forams and hydroid colonies [15:08:47] Matt Dornback leaves the room [15:08:56] Those amphipods would use their antennae as filter feeders. [15:09:09] partially educated guess...mudstone [15:09:34] We collected them with the Johnson Sea Link sub all over dead Enallopsammia coral branches in the Strait of Florida some years ago. [15:10:00] can we zoom at that Umbellula or what? [15:10:10] just passed [15:10:59] hermit crab with anemone [15:11:08] @tina - sorry, the current is whisking us away. [15:11:10] If those tracks are spatangoids like Moira, then I would think that we would see tests. [15:11:26] Can I get a frame grab of the cirrate octopod from the Serios feed? [15:11:35] with dirty hands [15:11:54] I like it. With tunicate [15:12:13] Oh anemone or tunicate on shell [15:12:22] anemone, trust me [15:12:30] there is also a snail shell [15:12:39] We're working on a frame grab of the dumbo octopus [15:12:50] I am not sure. Go with tina [15:12:59] Sorry [15:13:10] I never heard about tunicate-associated hermit-crabs [15:13:21] @michael - yes! [15:13:27] like it started with that and then the other critter overgrew it [15:13:43] it may be zoanthid, but from that progection only one polyp was visible, so I better go to anemone [15:13:49] me either... could the anemone be closed... or was it really a tunicate... [15:14:31] @les, polyp was partly closed and looking other side [15:14:51] @Tina, I think that is probably right [15:16:48] The anemone-hermit crab association is pretty common down here. Some details from a paper by Gusmao & Daly (2010): "Sea anemones in genera Adamsia, Calliactis and Paracalliactis (family Hormathiidae) engage in a mutualistic symbiosis with hermit crabs in which the anemone gains substrate and food in exchange for defending the crab. Some of the sea anemones also expand the living space of the crab by producing a carcinoecium, a chitinous structure that overlies the initial gastropod shell in which the hermit crab lives. The symbiosis is initiated either by the crab, or by the anemone." [15:17:02] leswatling leaves the room [15:17:35] thanks, Scott [15:17:51] I didn't get a good view of it, but we have seen venus flytrap anemones on the back of hermit crabs in the Gulf of Mexico. When closed, it's hard to tell what kind of anemone it is. [15:17:57] erikcordes leaves the room [15:18:39] Maybe hexactinellid, but I dont know more then that [15:18:49] Matt Dornback leaves the room [15:20:52] we have a question from the audience: Tyler Kronebusch Well I will definitely take advantage of this. Can apply to almost anyone on board. We always talk about favorites but we all know there's always something that has to balance this out. So what's everyone's least favorite task while on cruise? I'd have trouble with the deck position doing selfchecks. It seems like the pilot does a maneuver and deck interprets it as confirmation. I'd be very paranoid of getting that incorrect. It's like a morning pop quiz. [15:20:59] @Scott Thanks [15:23:40] 3 demosponges, 1 phekellia and two something else? [15:25:08] So I'm going to ask it...if we have a chance at some point today, could we perhaps collect one of the stick bryozoans? [15:27:05] the Mn coatings on these rocks seems extremely thick (which is kind of expected), but I don't think there is any record of nodules out here...if a collection stop happens, grabbing one of the lose rocks might be revealing [15:27:50] definitely support Megan's request. Would be very cool to know that they are in fact bryozoans, and if so, who they are. [15:28:23] Also, would like to know if we can get some estimate of current velocity. I am thinking that it may be limiting who can grow here.... [15:29:04] If we see another stick byrozoan, we will collect it [15:29:13] Heart urchin test to right or just sponge. [15:29:21] @Les thanks! If we can find a collectable rock with the bryozoans on it, that'd be great [15:29:45] I also support the collection of the bryozoan, but it was very small so we'd need to be in the right poition where the arm could reach it. [15:29:57] It was in earlier video [15:30:05] sponge for food.... these stars will eat anything! [15:30:18] Can you tell from the orientation of the satellite dish sponges which from which compass direction the mean bottom flow is moving? Is this area within the southbound thermohaline recirculation in the North Atlantic? The indications of at least periodic strong bottom flow suggests the same kind of westward intensification that the Gulf Stream exhibits. [15:30:34] Checking current speed [15:30:49] lazers just passed it [15:31:44] good spotting! [15:32:12] I keep loosing my video feed [15:32:21] same here [15:32:45] back now, but this is the 3rd or 4th time in the past 5 minutes [15:33:11] @santiago I'm glad to hear it isn't just me [15:33:25] Which feed is it that you are on and losing video? [15:33:43] feed 1 [15:33:55] no problem here in Maine [15:34:38] This is a depth record for a feather star in the Atlantic. The swellings on some of the pinnules are gonads. The family is Antedonidae, but this family has been broken up (polyphyletic). [15:34:50] Matt Dornback leaves the room [15:36:24] lesliesautter leaves the room [15:38:33] I have not seen any video break up on https://oceanexplorer.noaa.gov/livestreams/full-res.html [15:38:44] erikcordes leaves the room [15:38:45] Connection problems- we've checked and no problems were reported. Are you all about to get back in? [15:39:11] yep. No problem at this time. I'll let you know if it happens again. [15:39:21] The previous record is just over 2,075 meters SW of Iceland. The species might be a Thaumatometra; otherwise new. [15:39:26] I had few short breaking of video feed. mostly audio [15:39:40] Great- hope the problems were temporary [15:39:51] judging from current sours, etc., and orientation of ROV looks like current is from 270 or so. [15:40:13] ... and short pixelizing... [15:40:35] Current orientation is 200 degrees, but just moved from 270 or so [15:41:33] @Cheryl, I was watching as the ROV moved and at one point it was looking in the direction of the scour. [15:41:49] No parasites on rat. Disappointed. LOL [15:42:28] I am sure the fish in not disappointed! [15:42:41] Food is limited in the deep sea, so a lot of fishes don't move very quickly to conserve energy. [15:42:50] fish looks upset with something. look like my dog when she thinks that she is not enough fed. [15:42:50] lesliesautter leaves the room [15:42:55] no parasites that we can see... [15:43:06] Yes [15:43:21] .. yes.. food is limited, reason to be upset [15:43:21] scottfrance leaves the room [15:46:00] My name is said as hands connect. [15:46:13] It's Tamara Frank, People are always transposing my name, and surprised when they meet me that I'm not a Japanese male. [15:46:22] Question from the audience: From Tyler Kronebusch This questions can apply to almost anyone on board. We always talk about favorites but we all know there's always something that has to balance this out. So what's everyone's least favorite task while on cruise? I'd have trouble with the deck position doing selfchecks. It seems like the pilot does a maneuver and deck interprets it as confirmation. I'd be very paranoid of getting that incorrect. It's like a morning pop quiz. [15:46:33] lovely) perfect prononciation) [15:46:40] Thanks [15:51:09] thanks for answering the question! [15:52:50] Gotta go. I will check back in when I can. [15:52:57] michaelvecchione leaves the room [15:53:49] T is 2.2 and salinity is 34.8 which puts us at interface of North Atlantic Deep water and Antarctic Bottom Water. NADW flows south and AABW flows north [15:54:58] Spatangoid urchin feeding traces... [15:55:17] actually S is closer to 34.9 so the water is most likely more NADW, which explains the flow direction [15:55:24] Great question from Tyler! See you soon Micheal [15:56:39] This urchin must have been drunk... [15:56:54] Can't "walk" a straight line... [15:57:08] swimming shrimp [15:57:50] great explanation! [15:58:00] charlesmessing leaves the room [15:58:03] @ leslie Based on nearby ODP hole and projecting it out to the dive location, the rocks could be early to late Pliocene - upper Miocene claystone (diatom/nannofossil bearing) (with heavy emphasis on the could be) [15:58:27] Thanks for looking into all that! I'm very excited to be riding the NADW!! [15:59:13] I wonder if that has some bearing on Chuck's crinoid record... [16:00:33] More hydroid colonies... with barnacles? [16:02:24] @Leslie, I concur on difference and always getting a rock! [16:03:11] Looks like there's a bryozoan on a a sponge or rock in the back left [16:04:34] haha that's a coral [16:04:47] franktamara leaves the room [16:05:29] that's a coral... [16:05:40] More convergence! lol [16:05:58] there we go...that's the bryozoan [16:06:38] could be a coral also [16:06:55] only one way to know! [16:07:59] OK on my list of stuff to do is visit the Smithsonian and see/ID all the bryozoans Okeanos has collected [16:08:26] could be Paranarella, which we collected and Steve Cairns described from our seamount cruise. depth was 3900 m [16:09:21] Please record as a bio sample and put in biobox even if rock is collected. [16:09:42] i.e. rock is the associate not the primary [16:09:53] christopherkelley leaves the room [16:11:37] markbenfield leaves the room [16:11:46] As am I [16:11:57] lesliesautter leaves the room [16:13:13] Awesome [16:13:25] I'm such a wimp. I should call in [16:13:41] Thank you pilots! [16:13:56] well done! [16:14:04] But thanks for the collection! [16:14:28] But need to go. Will try to get back on before the dive ends. [16:14:50] @Megan: what are you afraid of? [16:15:26] leswatling leaves the room [16:16:11] @Scott I'm just not a phone person I suppose [16:17:17] hurrah for midwater :-) [16:19:44] @ScottF - definitely a bio sample with a rock associate. I'm reserving geo samples for the BIG boxes! [16:20:14] @Megan - next time! Please join the discussion. we want more voices. [16:20:52] leslie, you crack me up [16:21:43] Haha oh no I've been called out now! [16:22:39] @megan - no names were mentioned... :) [16:22:45] You know who you are! [16:23:37] @Leslie lol I know :) How about this. I'll call in now and then if you see any more bryozoans, zoom in and I'll talk about them. [16:24:09] new question from the audience: Carol Yates Wilkerson Serious question: do you guys get a hankering for a seafood dinner? [16:24:19] Good plan, Megan! [16:24:52] @Megan: don't make me talk about bryozoans! I'll call them ectoprocts... [16:25:10] I think it is feeding [16:25:52] Good that be Foram. [16:25:57] Star looks like a CIrceaster [16:26:08] OMG [16:26:17] Some Forams are stick like. Don't know size [16:26:45] Definitely a Goniaster though [16:27:11] The colony is so small it is hard to discern what type of polyps those are. [16:29:52] I'm having issues calling in - I'm typing in the correct passcode but it's telling me I'm pressing wrong or extra numbers and not letting me in [16:30:27] zachproux leaves the room: Replaced by new connection [16:30:43] Thank you Cheryl! [16:31:08] OK it worked that time [16:31:41] Now we just have to find a bryozoan! [16:32:15] Hi Cheryl, I just called in, too. [16:32:34] katerose leaves the room [16:33:48] Found this. https://goo.gl/images/MXEUkF [16:37:54] this is cool. is this a collection possibility? [16:40:09] @Andrea: which one? [16:41:06] the larger, unknown sponge [16:41:37] There may be a pink sea pen on the right of that sediment patch... [16:41:55] Have a look before leaving please [16:43:37] sea pen [16:44:00] is that a kophobelemnon? [16:44:35] There were also some other different sponges in the back, above this sand patch. [16:44:54] @cheryl if pomponi wasn't interested in a collection than I am not! [16:45:23] the sea pen may have been a kophobelemnon [16:45:37] lost feed to camera 1 [16:45:45] Okay, we'll move on. [16:45:47] video frozen [16:45:53] andrewobrien leaves the room [16:45:56] back [16:46:01] I've lost audio; I can see video though. [16:46:09] No, not a Kophobelemnon. Thgis one had distinct leaves. I think it was a back-side view of a Pennatula [16:46:16] got back [16:46:28] In Kophobelemnon, the polyps arise directly from the rachis [16:46:35] Theres a yellow and orange bumpy looking sponge above the lasers [16:46:45] Or, at least, not on distinct leaves [16:47:08] Thank you! Orange is OPH [16:47:53] Yellow sponge to the left please? [16:48:03] @scott that sea pen looked like the polyps arose from the rachis [16:49:01] lesliesautter leaves the room [16:49:12] I had a very clear view - definitely leaves with multiple polyps arising from them. [16:49:41] tomhansknecht leaves the room [16:52:35] squat lobster [16:53:05] Mycale? [16:54:35] A common pacific species of demosponge [17:02:38] My modem failed. Back [17:03:36] Crab or squat lobster? [17:05:21] I agree with Tara - it's a squat lobster [17:05:34] Oh, that would be good! I love the two-fers!!! [17:05:47] Matt Dornback leaves the room [17:07:19] Is there sponge stuck to the claw? [17:08:02] robertcarney leaves the room [17:08:58] franktamara leaves the room [17:09:06] FAN!!!! [17:09:44] @shirley something was on it, but it fell off at the end. we reviewed the video. [17:10:06] We have not seen this shape with the branching [17:10:24] Phakellia sp. an Axinellid demosponge [17:10:41] Hi everyone -please feel free to jump on the phone line to help narriate the dive. It's always more interesting for people to listen to multiple voices, and it's the best/fastest way for you to interact with the science team! [17:11:11] upasanaganguly leaves the room [17:11:22] Predatory tunicate. [17:11:46] What is in tunicate. Were those egg cases of copepod? White paired things. [17:14:01] I saw those too and guess copepod. Not sure what that spiraling white thing was though [17:14:20] I was away from the screen [17:14:30] Find more of those tunicates please and lets look at symbiotes. [17:14:59] @Thanks Megan Interesting [17:15:29] May be a feeding structure. We will keep an eye out for more [17:16:48] nicolemorgan leaves the room [17:17:02] If it was an octacnemid tunicate, they often have a polychaete associate [17:17:18] Geodia pachydermata [17:17:58] @scott I saw that polychaete next to calcareous object on right. The copepod was on left. [17:20:19] Don't try to dislodge them - take the whole. [17:20:27] Sorry - too late. [17:20:38] Picking up yellow one also? [17:20:51] Do any macroinverts come up with these collections: tubiculous amphipods or tanaids. I worked on tanaid publications. [17:22:44] I'm not asking for another collection - I meant if both sponges were coming up together we should take advantage of the opportunity to sample them both and not take the time to try separating them. [17:23:00] Easier to convey that over the phone but I didn't want to interupt [17:23:21] sandrabrooke leaves the room [17:25:39] Nice collection Thank you! Bonus associates also. [17:26:22] update regarding water column transects timing transects will start at ~~1555 EDT/1255 PDT . The "pre-dive" call to discuss the transects and provide context for folks at home will be at ~~1540 EDT/1240 PDT. [17:27:19] for our benthic explorers, we will have our regular dive planning call will be at 1435 EDT/1135 PDT [17:31:02] Not hearing any audio on call or video... [17:32:11] I think your mic is off or misplaced... [17:32:24] Can barely hear you Leslie. [17:32:54] My bad! I think I had my phone volume turned down! [17:33:07] Sorry! [17:33:07] franktamara leaves the room [17:34:01] No worries- I was just about to ask, but won't now! [17:35:33] This might be in the Freyellid group of Brisinigdae. I think because of the depth as well as the slight bulge at the base of each arm ray. [17:36:26] But we'll have to turn on our Seastar Signal on for Chris Mah to be sure! [17:37:13] hang on...working on it. Tweeting it now [17:37:30] Freyellids tend to be quite a bit deeper then the Brisingids. [17:38:42] @Tara Thank you! [17:39:31] katerose leaves the room [17:40:26] It worked yesterday, but not today so far! [17:40:26] lesliesautter leaves the room [17:40:54] Just as a note... These "brisingid" asteroids belong to the Order Brisingida, which includes the families Brisingidae and Freyellidae. So the general term "brisingid" is appropriate for both, and if we have enough info or expertise then we can ID to Brisingidae or Freyellidae [17:42:04] @Scott Thank you, I get confused and mixed up on that some times. [17:42:22] @Nolan: no worries - I wasn't criticizing you! [17:42:44] I just wanted to be sure those less familiar knew you could refer to those seastars in general as brisingids. [17:43:10] I welcome your being more specific to freyellids. [17:43:51] @Scott I know you weren't. I'm still learning! Some day I might get close to being like Chris M with sea stars or like Chris K and Shirley with sponges! [17:44:19] tunicate for me [17:44:34] and the stick [17:45:12] Yes Tina - I was wondering about the "stick"! [17:45:25] sorry, have to leave now. how long we are staing at the bottom? [17:45:35] Coral or sponge or...? [17:45:42] @Tina: about 45 minutes [17:45:59] stick looks more coral for me.. but as well we are too fa5r to be sure [17:46:23] @Nolan - since you are only, what 22, I think you are WELL on your way! [17:46:30] Ok, will wait for collection then [17:46:43] Hope we may be able to collect all 3 (tunicate, rock, and white coral/sponge [17:47:08] scoop? [17:47:47] Yes, getting out the scoop [17:47:58] @Leslie Yep, hahaha! Thank you, I gotta start somewhere! [17:48:53] @Tina: I agree on stick. I'm think small primnoid [17:49:09] scooping Anthomastus was proved to be absolutely effective [17:50:36] That looked like anice scoop. [17:50:46] not an anise scoop, a nice scoop [17:50:53] Might get some infaunal macroinverts. [17:51:00] better separate [17:51:10] That would be a great bonus. [17:51:28] stevenauscavitch leaves the room [17:51:32] if stick is at surface?? [17:54:38] Cool, nice job on the small stuff. Looking forward to the deck shots of that stick... hint, hint! ;-) [17:54:53] magnificent arm. Thanks to Department of Justice and Dennis [17:55:19] Ok, sorry, have to go, wish you great remain of the dive! [17:55:26] Amazing Pilots! Thank you! [17:55:40] @Tina Thank you and great to have you! [17:55:50] pilots are gods of arms and manipulations [17:56:04] @Tina Absolutely! [17:56:04] tinamolodtsova leaves the room [17:57:28] Yes they are! Thanks for joining us Tina! [17:58:37] heatherjudkins leaves the room [18:00:53] What if you dig with claw at blind end of those trails? Is the spatangoid there? What is the genus? It is just amazing to see all these trails with no excavator. [18:02:27] Is it manmade? [18:02:40] We did see a spatangoid shell yesterday, but we rarely (if ever) see a live one. I don't think we've ever tried digging at the end of a trail. [18:02:53] :) [18:03:15] But I think these are spatangoid trails. [18:03:28] santiagoherrera leaves the room [18:03:49] I thought I was looking at a can, not a rock! [18:04:04] @scott thanks [18:05:10] Now it looks like a rock! [18:06:35] I sure would've been embarrassed had it been a brick! :) [18:06:48] Thank you. Checking out. [18:06:57] Quite a beauty! Leslie can't stop smiling [18:07:43] Do you sign out or just close window? Thanks [18:08:33] tomhansknecht leaves the room [18:08:44] If you close the window, you should be signed out. [18:08:57] Thanks for joining us Tom! [18:09:27] lesliesautter leaves the room [18:13:04] And next to that sea cucumber is a demosponge--most likely another species of Geodia! [18:14:11] there's a stick-like coral(?) in the background behind the holothurian [18:14:52] It was my phone disconnecting...we're in the middle of a bad thunderstorm....I'm calling back in... [18:16:06] Since sea cucmbers are relatively easily collected by scientific trawls, I would not be inclined to collect one unless we had an echinoderm expert tell us what we were looking at was something unusual, new, or otherwise worthy of collection. [18:20:26] @megan - sorry we didn't get your comment in time to look! [18:20:48] Oh that's ok. It wasn't a bryozoan [18:21:02] small plexaurid below [18:21:34] sabellid polychaete more likely-in the mud tube [18:21:47] coral on the substrate [18:22:27] the thing on the worm tube looks a bit like ascothoracid [18:22:39] don't know if they live on worm tubes, though [18:23:15] Okay, I think we've got half the phyla guessed... :-) [18:23:26] les-that's a mouthful [18:23:48] I'll my bryozoans got replaced by primnoids :( [18:24:07] Tit-for-tat, Megan! [18:24:15] ...all...not I'll. It's Friday. [18:25:06] @megan today is Friday??? [18:25:47] So dive planning to take place in 15 minutes? [18:26:02] laurenwalling leaves the room [18:26:18] It is Friday, right? I'm not going crazy? [18:26:36] I have no idea out here! :) [18:26:44] @Megan Gosh, I hope its Friday! Otherwise I'm really mixed up! [18:26:56] Dive planning for dives 3 & 4 to take place at 1445 EDT.... about 19 min from now. Please join us. [18:27:06] amandademopoulos leaves the room [18:27:07] Rats, I just got back! Oh well, what I saw was great! [18:27:22] see you in 15 minutes [18:27:36] Haha OK. Then yes, it's Friday! [18:27:57] I have to go work in the lab. Thank you for a great dive and extraordinary collections everyone! [18:28:05] nolanbarrett leaves the room [18:28:24] michaelvecchione leaves the room [18:28:51] Thanks all! [18:28:56] zachproux leaves the room [18:29:06] EX1806_DIVE02 ROV Ascending [18:29:09] meganmcculler leaves the room [18:29:40] leswatling leaves the room [18:30:01] Thanks everyone for joining us, and hope to see you again at 15:55 for midwater transects! [18:30:07] enriquesalgado leaves the room [18:30:34] franktamara leaves the room [18:33:24] jasonchaytor leaves the room [18:33:29] shirleypomponi leaves the room [18:36:43] andrewshuler leaves the room [18:37:28] georgematsumoto leaves the room [18:48:07] HI George! [18:52:58] lesliesautter leaves the room [18:58:19] asakomatsumoto leaves the room [18:59:20] Hi Leslie, drats, gotta go give a tour :-(, I'll be back soon [19:00:44] scottharris leaves the room [19:17:16] taraluke leaves the room [19:23:34] jillbourque leaves the room [19:32:52] amandanetburn leaves the room [19:35:14] jamesmurphy leaves the room [19:59:10] Is there someone who's doing seascribe for the midwater? [20:00:32] Hope so, but I can't commit. Will help as I can. [20:00:59] we will have someone here to help shortly [20:03:32] Solmissus [20:06:48] Cyclothone [20:07:13] They are the most common.... we collect lots in the trawls we do in the GoM [20:08:32] Radiolarian I think [20:08:45] Ctenophore [20:09:13] don't think it's a lobate [20:10:04] Ctenophore [20:10:51] Solmissus [20:11:42] Larvacean [20:13:08] Salp chain [20:14:13] End 800m [20:14:59] thanks heather - you can also log this info in the annotation tool we use seascribe - link to today's dive is here: https://divelog.oceannetworks.ca/Dive?diveId=1223 [20:16:12] "object object" [20:18:30] thanks heather - you can also log this info in the annotation tool we use seascribe - link to today's dive is here: https://divelog.oceannetworks.ca/Dive?diveId=1223 [20:18:42] how's that [20:22:09] Nope. still "object object" [20:23:06] @Kasey: hang on. I'm going to have one of my students check what she sees. [20:23:29] ctenophore [20:23:47] @Kasey: Upasana sees the same "object object" in her browser (Chrome) [20:24:38] hmmm I wonder if it is when I insert a link [20:24:48] thanks heather - you can also log this info in the annotation tool we use seascribe [20:25:00] @Kasey: Lauren also sees "object object" and she is using a PC vs our Macs... [20:25:09] thanks heather - you can also log this info in the annotation tool we use seascribe - link to today's dive is here: https://divelog.oceannetworks.ca/Dive?diveId=1223 [20:25:26] "object object" [20:26:01] Hello! [20:26:22] hi! [20:26:36] Apologies - I did not hear who is leading the audio portion here... Is this Stephanie? [20:26:58] Stephanie Bush [20:27:17] Thanks Kasey - I could read that! [20:27:27] our sample data manager has a not so hidden talent of mn expertbeing a water colu [20:27:39] Start 700m [20:27:50] I'm sure that was a total coincidence... NOT [20:27:59] off my computer problems today - ** our sample data manager has a not so hidden talent of being a water column expert [20:28:23] Oops, sorry, thought someone said that it started [20:29:59] marine snow- possible larvacean house [20:30:54] siphonphore [20:31:23] Cyclothone [20:31:59] radiolarisn [20:32:08] or a foram? [20:32:22] Amanda, you're correct- [20:32:36] chaetognath [20:33:00] oops, not chaetognath.... [20:33:21] siphonphore [20:33:58] hatchetfish [20:34:11] maybe. [20:34:26] cyclothone??? looked like their swimming behavior [20:35:11] the small white objects could be pteropods, would need to zoom to be sure [20:35:21] Forskalia [20:35:30] siphonophore [20:35:47] Hi George! [20:35:56] Glad to be back :-) [20:37:44] krill [20:37:52] Tammy, species? [20:38:29] sergestid [20:38:38] sergestid [20:39:15] missed it - right now, that's a sergestid [20:39:21] end 700m [20:44:15] I am not dialed in right now. [20:44:56] Upasana smiled, so I guess you pronounced it right! :-) [20:45:05] awesome! [20:45:34] It is you-pah-shaw-na [20:46:45] You could also say that many of the small white objects could be small crustaceans, pteropods etc. [20:47:01] As some of it is moving not like the marine snow [20:48:03] Did you guys see any DSL? and if so, what depth? [20:48:33] you should be able to see it on stream 3 (though it's kind of hard to see) [20:48:59] Thanks! [20:50:45] 600m start [20:51:14] pretty weak layer at 500 in the 18 kHZ, 500-700 in the 38 kHZ [20:51:40] yeah, that's what it looks like to me as well [20:52:11] copepod [20:52:16] andreaquattrini leaves the room [20:52:41] aphipod [20:52:54] amphipod [20:55:18] siphonophore [20:55:31] Many of these jellies are bioluminescent [20:56:34] cyclothone [20:56:41] lobate ctenophore [20:57:05] Thallasocalyce - not really a lobate, but probably close enough [20:57:19] Larvacean [20:57:38] different house structure, interesting [20:58:12] radiolarian? [20:58:27] I heard "several" houses per day [20:58:51] franktamara leaves the room: Replaced by new connection [20:59:14] drats, gotta go to a meeting. find more jellies :-) [20:59:32] GeorgeMatsumoto leaves the room [21:00:26] krill [21:00:52] done 600m [21:01:36] bilobed euphausiids aren't krill; only the swarmers, like Meganyctiphanes norvegica and Euphausia superba, are [21:02:17] thanks, Tammy! [21:05:57] My favorite: Phronima hyperiid amphipod - the creature in Alien is a total ripoff of this beast! [21:07:08] Also, a creature whose entire head is an eye is also pretty cool [21:07:20] only the deeper living hatchfish have upward looking eyes - the shallower ones have the normal fish eyes [21:07:50] makes sense! thanks [21:08:03] upasanaganguly leaves the room [21:09:35] Phronima also uses pyrosomes to make their barrels; they discard their barrels as they grow, and make a bigger barrel when needed; sometimes the males take the discarded barrels as their own [21:10:00] thanks Adrienne! [21:13:18] 500m start [21:13:53] siphonophore [21:15:24] siphonphore [21:15:42] Oh man! Not fair. I want to choose a favorite in every phylum! :-) [21:16:17] worm... forgot name [21:16:27] go for it, scott! [21:17:23] the deep corals don't have zooxanthellae - need to rely on plankton in the water column for food [21:17:32] After teaching for 20+ years, I can't ever decide on just one so go for a favorite in each :) [21:18:32] radiolarian [21:18:50] chaetognath [21:21:04] siphonophore [21:22:13] there are live ones in this mix- they are moving different than the snow.... would be hard to get a good shot- would take some time to sort through snow vs. pteropod [21:22:47] was that a heteropod? [21:23:49] end 500m [21:24:29] Is there time for a 400 m? [21:24:43] (in addition to 300?) [21:24:50] Would be great to be consistent if we could get a 400m [21:25:02] and a 300 m [21:28:29] No, not arbitrary at all. Epipelagic is defined as the zones in which there's enough light for vision and photosynthesis. Mesopelagic is the zone where there's enough light for vision, but not photosynthesis. 0-200 and 200-1000 m is for clearest ocean water, so depth ranges change in more turbid waters. [21:30:48] Oops - should have said downwelling light; there's always going to be bioluminescence. [21:37:01] Tammy, you should call in sometime! Full of info. [21:38:57] not sure if your question got answered - we have some confusing seas out here, so the "extra" time for the dive is for us to navigate those for a safe recovery [21:41:43] all good. Thanks! [21:41:55] Yeah, but then I'd actually have to answer questions . . . [21:41:59] Just channeling my inner Mike Ford and being greedy! [21:42:27] haha - join us next time ! our next transects are on Sunday [21:43:06] hahaha. We'd love to hear them though. [21:44:17] laurenwalling leaves the room [21:44:20] quick intros... [21:46:41] Tammy where are you from? [21:46:57] -institution? [21:47:53] 300m start [21:48:02] Nova Southeastern University in Fort Lauderdale, Florida [21:48:25] Hi! [21:48:34] thanks [21:48:43] :-) [21:48:47] what is that? [21:49:37] Stephanie is at dinner , so please speak up ! [21:49:45] unless you want to hear me talk about corals..... [21:50:37] thanks Amanda [21:52:41] chaetognath [21:53:32] the sharks of the worm world [21:55:12] chaetognath [21:55:18] I like that description. [21:55:32] :) [21:56:29] Or maybe to poke my fish colleagues I'll start referring to sharks as the chaetognaths of the fish world... [21:57:09] siphonophore [21:57:53] pretty Forskalia [21:58:00] larvacean house [21:58:13] end 300m [21:58:26] Sounds like it is time to go. [21:58:35] "See" you all tomorrow. [21:58:46] Smooth sailing. [21:58:51] Thanks everyone! See you next time! [21:59:01] sigh, my timing sucks today. [21:59:22] Sorry, George! [21:59:30] Thanks everyone! Good-bye [21:59:43] Thank you all, great job steph et al.
