We are approaching the dive site now. The winds and seas look good. We just powered on the ADCPs so we will know about the currents shortly. We did arrive a bit later than normal. So deploymenet will likely be around 0900 ship time as projected in last nights email [17:06:24] For this cruise we have a new ONC server that is dedicated to NOAA operations. This should prevent the slow downs we had last cruise. So please access Sea Scribe through this link. https://divelog.oceannetworks.ca/Dive?diveId=504 [17:06:54] here is the link to the video http://oceanexplorer.noaa.gov/okeanos/media/exstream/exstream-full-res.html [17:25:48] briankennedy leaves the room [17:28:21] stevenauscavitch leaves the room [17:36:05] Pre-DIVE01 test [17:48:40] andrewobrien leaves the room [17:57:30] katharineweathers leaves the room [18:00:50] test2 [18:04:45] looks like we may be able to get in the water earlier than 9 ship time [18:06:06] great!

[20:16:08] amazing number of ACNs.. [20:16:45] Just tuned in... Are those black coral spiral whips, or ellisellids, or something else?

It is a very diverse family, we tend to overlook them and not collect them, and I have a PhD student who has begun a project on the group, so we'd actually learn something about it. [20:18:44] well...I don't think it is Acanthogorgiid, could be Plexaurid [20:18:46] I don't think Acanthogorgia. [20:18:55] Scott, Stichopathes I think. They zoned one earlier [20:18:57] I think likely Paramuricea [20:19:02] @Chris: thanks [20:19:10] LAT :-11.04774, LON : -171.11099, DEPTH : 1133.7897m, TEMP : 3.93898C, SAL : 34.53804 PSU, DO : 3.74527 mg/L [20:19:20] I agrtee with Andrea: looks more like a paramuriceid than acanthogorgiid. [20:19:30] Yea, not so sure its Acanthogorgia either, Andrea [20:19:46] I agree with Paramuricea [20:19:50] The acanthogorgiids typically (though not always) have thinner coenenchyme [20:20:35] spectacular pillow basalts in the field of view [20:20:38] what was the yellow stony coral? [20:20:47] HOL [20:20:56] Enallopsammia likely [20:20:57] One thing to note: most of us are used to see the genus Acanthogorgia, but there are other genera in the [nominal] family thta look pretty different, e.g. Calcigorgia (although we should not find Calcigorgia this far south - I use it only as an example) [20:21:41] Oneirophanta sp. holithurian?

[20:45:08] I'd like to hear from Chris, but my understanding is that the taxonomy of sponges is not based on the overall morphology, but spicule details, and so a large piece isn't really necessary. [20:45:22] agree with scott [20:45:32] Sorry Scott, stepped out for a second. Yes, didn't need too much but now they have a nice piece. [20:45:43] I think the shrimp wants to go into the biobox [20:45:57] There are old shrimp and bold shrimp, but there are no old, bold shrimp? [20:46:08] ok thanks shoreside, we will be sure to be conservative with sponge collections [20:47:02] My point was to make it easier on pilots when collecting soft sponges, but also for preserving as much as possible in situ.

[21:31:54] adriennecopeland leaves the room [21:31:55] Note this one is also growing on the tip of a feature and not flattish bottom. [21:31:56] It warms my heart that aplacophorans are on folks' radar :) I don't see any here, though. [21:33:02] collect! [21:33:27] I understand all the downsides so we can move on if necessary [21:33:33] Agree with Asako! Very strange acanthogorgiid like thing. [21:33:43] rolandbrian leaves the room [21:33:46] But I do think this is something we have not previously collected and could be a Muricella [21:34:13] BY "not previously collected," I mean during the past 2 years of CAPSTONE.

No calyces for polyps to pull into [21:34:54] @Les: I agree, but I'm leaning to Acanthogorgiidae [21:34:57] so that argues for acanthogorgiid, but sclerites not right [21:35:43] @Les: do you have Grasshoff's New Caledonia gorgonians book? Sclerites resemble Muricella, possibly. [21:36:11] @Les: but I'm not sure the axial coenenchyme is thick enough. [21:36:25] @Les: so, can't say for sure what it is. [21:37:27] @Scott, just checked out Grasshoff... the sclerites in Muricella look quite large [21:38:11] also, the polyps when contracted form low domes, as he says [21:38:46] but I think the family is right.... guess we'll see.... [21:38:56] @Les: yes, but these aren't contracted! :-) [21:38:58] @Les: there are so much variation of size of sclerites of Muricella. (it does not mean I am sure this is Muricella or not) [21:39:04] oph arms resemble ophiacantha [21:39:19] LAT :-11.04737, LON : -171.11096, DEPTH : 1100.6321m, TEMP : 4.16923C, SAL : 34.52852 PSU, DO : 3.73633 mg/L [21:39:35] @Les, Asako: plus there are Anthogorgia! [21:39:58] Excellelent zoom on ophs and hydroids [21:40:05] With thta close-up I'd say no question this is an acanthogorgiidae, at any rate. [21:40:14] also has a solitary hydroid on polyp [21:40:28] Wonderful collection. When are you bringing it to shore? ;-) [21:40:48] definitely an acanthogorgiid.... [21:40:49] @Scott: I am currently work on Japanese Anthogorgia and Muricella! and some of them may be the same! [21:42:16] @Asako, I can see that could be possible from the images in Grasshoff's book [21:44:12] @Les: agree. its very difficult to distinguish by the images.

I am sorry I missed it. I can't watch much of this leg. It is a Chiroteuthis, either C. picteti (http://tolweb.org/Chiroteuthis_picteti/19477) or C. spoeli (http://tolweb.org/Chiroteuthis_spoeli/19478). My guess is the former, but without confidence. Both species are pretty variable." [21:52:21] Beautiful Anthomastus [21:52:48] Depth 1095m [21:53:02] Agree with Amanda. I think this has been a good start to the dive - good views and characterization of some fairly dense corals, anemones and sponges and even some collections. Now spend some time making way.
