[00:00:08] <stevenauscavitch> An identical one was seen in Johnston (EX1504) and IDd to the edwardsiidae family
[00:00:29] <stevenauscavitch> They're hard to sample because they escape into the sediment.

[00:38:27] <asakomatsumoto> it looks similar for me.
[00:39:24] <asakomatsumoto> but I thought we have seen different paramuriceid.

[00:55:16] <stevenauscavitch> Good observation! No bamboos so far that I've seen. Very unusal for this depth
[00:55:55] <briankennedy> saw two so far

[01:02:16] <asakomatsumoto> we saw only one Primnoid....
[01:02:37] <stevenauscavitch> also surprising!

[01:05:07] <asakomatsumoto> however, we saw large solitary hydroids.
[01:06:27] <asakomatsumoto> that is the highlight of this dive!
[01:07:32] <asakomatsumoto> that is the best video ever for that genus!

[01:10:10] <stevenauscavitch> Im thinking damage. the brittle star is still Ophiocreas which us always a 100% match to Metallogorgia melanotrichos
[01:11:11] <briankennedy> steve do you want a water sample at the end of the dive?
[01:13:25] <stevenauscavitch> yes, that would be a good idea. and the one bottle near the deep scattering layer if you have one left

[01:22:50] <stevenauscavitch> sea pen just below and to the right, a red stick
[01:24:10] <stevenauscavitch> There may be small critters inside the Xeno. As the sample warms on deck they should crawl out.

[01:29:23] <briankennedy> will but but I will be shocked it surives

[22:53:53] <christophermah> thank you. I could not locate any in the USNM collections given these parameters.. depth, location, etc.
[22:55:29] <christopherkelley> Good, likely an undescribed species.  The closest I can see in the guide is Phymorhynchus sp in the family Raphitomidae.  It was recorded almost as deep as this

[23:09:20] <valfinlayson> we've found these in PMNM before

[23:17:59] <asakomatsumoto> I know that story about her feet, Chris ))
[23:18:29] <christopherkelley> Val, I asked a question of you earlier when you were offline.  Would these nodules be richer in minerals since they are right in the middle of a fracture zone?  I don't know if that is the reason the CCZ is so attractive for nodule mining
[23:19:26] <christopherkelley> ophidiid
[23:19:46] <valfinlayson> sorry I missed that earlier, Chris! I was probably making dinner. That's a great question, and honestly I have no idea. I guess it would depend on whether there were hot fluids coming out of the FZ, and what kinds of FeMn crusts these are
[23:21:21] <christopherkelley> Hmmm, the only one I know this deep is Leucicorus sp so perhaps its in that genus.  Those are mostly white like this one too.
[23:22:19] <valfinlayson> There are zones throughout the Pacific where different kinds of ferromanganese crusts are common - some more economic than others. Here's an example of where cobalt-rich FeMn have been mapped (which correlates closely with hotspot tracks) https://www.geomar.de/en/research/marine-resources/mmr/mineral-resources-2-1-2

[23:22:27] <christopherkelley> Thanks Val.  I think that is why people think the CCZ nodules are higher quality.

[23:22:45] <valfinlayson> Probably!
[23:22:49] <christophermah> this is a sea pig, Scotoplanes or somesuch
[23:23:20] <christophermah> the poop; is visable through the body wall
[23:23:25] <christophermah> a sea cucumber
[23:23:31] <christophermah> family Elpidiidae, an elasiopod
[23:24:21] <christophermah> all things considered, we don't see these as often as we would like
[23:24:32] <christophermah> its the legs

[23:29:03] <briankennedy> Thomas what do you want to see on these rocks
[23:30:25] <thomasmorrow> We're seeing it, this is great. If we see something loose that appears in place and can be grabbed that would be great, but it's going to be a challenge with what looks like a thick crust.
[23:31:32] <valfinlayson> second Thomas' recommendation. It's going to be tricky to find anything loose, but anything would be great around here
[23:31:35] <sarakahanamoku> Chris Mah  - just wanted to say personally THANK YOU for answering my mom's question!

[23:32:47] <thomasmorrow> Just a quick look around the base, no need to linger, we can keep up with the ship moves to climb
[23:32:57] christophermah leaves the room
[23:34:13] <christopherkelley> I see some rocks that look loose
[23:34:33] <valfinlayson> looks like talus on the right side of the screen
[23:34:41] <valfinlayson> that may be loose
[23:35:01] <valfinlayson> Chris, are you sure you're not a geologist??
[23:35:05] <thomasmorrow> Val, Chris, you're more experienced than me, if you see something ideal go ahead and make it known!
[23:35:30] <christopherkelley> bolosominae.  Can only go to subfamily on that one
[23:36:03] <christopherkelley> I think some of the angular ones sitting in sand pockets might be loose
[23:36:08] <valfinlayson> yes
[23:37:05] <valfinlayson> Off camera to the right, there's a talus slope with possibly loose rock fragments. They're not in place anymore, but could be sampled

[23:37:41] <christopherkelley> Val, I'm the family black sheep.  My father and brother were both geologists.  I had a pick in my hand before I was 10
[23:38:17] <valfinlayson> That makes sense, Chris!
[23:38:59] <christopherkelley> Welllllll, maybe still a euplectellid in the subfamily bolosominae.  It could also have been a Caulophacus in the family Rossellidae but I think my first guess is better
[23:39:03] <asakomatsumoto> you have a long experience with rocks, Chris!
[23:39:40] <christopherkelley> I also like rock music, Asako!
[23:40:59] <christopherkelley> Chris Mah, is this Freyastera sp?
[23:41:19] <valfinlayson> you can see the striations from the current in the crusts
[23:41:24] <christopherkelley> Looks like them and the depth is right.

[23:44:14] <valfinlayson> hahaha, i wish we could get that big one!
[23:44:38] <christopherkelley> commatulid, I agree Brian.  But the other 2 seastars weren't brisingids but rather freyellids.  Chris isn't on right now but I'm pretty sure about those seastars
[23:45:14] <valfinlayson> Not seeing any rocks we can pick up yet. Best to try to look for talus

[23:47:59] <christopherkelley> Sorry guys.  We have company tonight and I have to do some prep now.  Have a great rest of your dive.
[23:48:03] christopherkelley leaves the room
[23:49:11] <asakomatsumoto> see you Chris!
[23:50:37] <valfinlayson> Have a good evening, Chris!

[23:53:44] <valfinlayson> left of lasers looks better?
[23:53:50] <valfinlayson> might be mostly crust, hard to tell
[23:55:07] <valfinlayson> Agreed, Sara!
[23:56:35] <thomasmorrow> Val, do you want to get together with Ashton and write that "what makes a good ROV rock selection" paper we've all joked about for too long?
[23:56:51] <thomasmorrow> Or has someone done that

[23:57:40] <valfinlayson> Look to the right, I think there might be rocks there
[23:58:28] <valfinlayson> A lot will be stuck to the seafloor, but there's a better chance of being able to pop something off
