[00:01:45] I honestly don't think we have ever sampled that sponge species before so thank you very much. [00:02:21] fantastic, happy to help Chris! thank you for the guidance [00:03:11] LAT : 28.878854 , LON : -177.869188 , DEPTH : 2050.2309 m, TEMP : 1.84263 C, SAL : 34.61769 PSU, DO : 2.79817 mg/l, TURBIDITY : 0.0611 FTU [00:03:59] Thanks to the pilots for a great job collecting it! [00:05:16] Tretopleura sp, not the same thing as you sampled [00:05:51] Munidopsis sp is the white squat [00:07:21] how many of these Munidopsis (no associated with corals) have we collected from this area? [00:08:11] LAT : 28.878885 , LON : -177.869195 , DEPTH : 2050.4284 m, TEMP : 1.84442 C, SAL : 34.61598 PSU, DO : 2.87089 mg/l, TURBIDITY : 0.0549 FTU [00:09:37] I don't think we sampled very many at all during Capstone. [00:10:09] not a good place to try and sample with this current [00:10:14] I think this is munidopsis albatrossae. Its known for the long rostrum. https://www.soest.hawaii.edu/DARC/PMNM/guideimages_php/Galatheoidea_009.php?category=Galatheoidea [00:11:06] Yea, I was going to say that many of the munidopsis in the guide have names because they are fairly distinctive just from video [00:11:47] Probably Tromikosoma hispidum for the urchin [00:13:12] LAT : 28.878923 , LON : -177.869066 , DEPTH : 2047.272 m, TEMP : 1.82632 C, SAL : 34.6178 PSU, DO : 2.82045 mg/l, TURBIDITY : 0.0672 FTU [00:13:23] Shucks guys, its again my night to make dinner. Sorry but I have to sign off. By the way can you zoom this sponge? [00:13:42] I think it is Lefroyella sp [00:13:51] thanks for sticking with us chris [00:13:56] Just looking, not collecting. [00:14:00] gotcha [00:14:01] was about to ask [00:14:39] see you Chris! [00:14:47] I'm looking for commensal anemones can they zoom more [00:15:10] yes, they are [00:15:14] Yep, you can see the aemones [00:15:24] Lefroyella sp for sure [00:15:51] Yes, good thanks [00:16:10] Have a great rest of dive! [00:16:48] christopherkelley leaves the room [00:17:57] Sara I emailed you an urchin with boots [00:18:13] LAT : 28.878986 , LON : -177.869047 , DEPTH : 2047.8141 m, TEMP : 1.8308 C, SAL : 34.61814 PSU, DO : 2.84731 mg/l, TURBIDITY : 0.0611 FTU [00:18:17] beautiful shot!

[00:23:33] can steve [00:23:42] wow [00:23:56] crusty hydrothermal chimney maybe? I don't know yet. Any chance the pilots could hop into the water column to see the top of it? [00:24:13] Hemicorallium high density [00:24:37] I've seen big honkin hydrothermal chimneys before, but not this old and I'm not sure if they can survive this long [00:25:18] and Narella on the wall [00:25:24] If this is a dike standing on its own, that's pretty remarkable [00:25:35] yeah im fucking wierded out by that [00:25:38] like what [00:25:42] me too [00:25:43] .... or is it a chimney? [00:25:46] what the fuck [00:25:52] sorry this is archived isn't it. apology for swearing [00:25:53] I don't know. Need to see more of it [00:25:56] lol [00:26:31] can we take it with us? [00:26:35] lol [00:26:47] Hippasteria [00:27:50] 2044m is bottom of rock, will see depth at top [00:27:58] Yeah, Chris will definitely like this [00:28:10] Asako too!

[00:29:04] In the right spot the Hemis can be extremely dense and large [00:29:16] camera 2 view is bonkers [00:29:29] holy moly!!! [00:29:32] I've seldom seen vertical hemicorallium reefs though [00:30:13] Val, you are right! [00:30:15] There are burrowing polychaetes that are parasites of the coral. [00:30:36] i need a bigger computer screen [00:30:41] Calyptorophora/Paracalyptrphora? [00:31:01] Gorgoniapolynoe caeciliae is the genus and species that is often associated with Hemicorallium [00:31:04] dike [00:31:19] that's columnar jointing [00:31:28] why is it still standing [00:31:31] lindasunderland leaves the room [00:31:47] this is intrusive rock so there was once rock around this [00:31:53] oh my gosh [00:31:57] TOTALLY WEIRD [00:32:02] I LOVE IT [00:32:56] we see stuff like this on land, but this is the first time I've seen a vertical dike do this on the seafloor [00:33:05] new favorite rock [00:33:15] LAT : 28.879222 , LON : -177.868961 , DEPTH : 2035.9701 m, TEMP : 1.83558 C, SAL : 34.61777 PSU, DO : 2.83389 mg/l, TURBIDITY : 0.0611 FTU [00:33:28] I want to know its story [00:33:39] me too can we befriend this rock?? [00:34:10] something makes it resistant enough to stay intact when everything else around it . . . didn't. [00:34:44] And it's crusty-looking enough that it's been like this for a long time [00:35:03] what the heck were the other rocks made of [00:35:21] As a geochemist, I'll be able to tell you that, lol [00:35:29] yay i cant wait!!! [00:35:33] Well, maybe not since they're elsewhere [00:36:30] samcuellar leaves the room [00:36:31] I guess it's rock o'clock (but not the sampling kind) [00:36:35] both geologists and biologists are happy with this rock [00:36:42] i wish it were rock oclock - the sampling kind [00:36:46] Asako, yes! Great rock [00:36:51] :-) [00:37:18] zoom? [00:37:27] I couldnt see the polyps well [00:37:30] What's the orientation of this dike? [00:37:46] But my sense is probably Paralcayptrophjopra [00:37:50] zoom please [00:38:12] wonder whether it's aligned with the rift we just came up [00:38:17] LAT : 28.879243 , LON : -177.868946 , DEPTH : 2035.1823 m, TEMP : 1.82632 C, SAL : 34.61817 PSU, DO : 2.87609 mg/l, TURBIDITY : 0.0611 FTU [00:38:18] val the dike runs due north [00:38:23] well sorta [00:38:26] Thanks! [00:38:28] we are facing due north about now [00:38:36] so more like northeast southwest [00:38:38] sorry [00:39:02] Roughly aligns with the big linear structure that goes through the summit then [00:39:06] cool [00:39:13] ooooo [00:39:57] strap it up and take it home. [00:40:01] georgematsumoto leaves the room [00:40:08] it's about 15m from top to bottom on this side Val [00:40:13] Sam, yes plz, haha. This is spectacular [00:40:31] in terms of linear height [00:40:40] Wow! Thanks, Sara. That's a big outcrop [00:40:58] esriously [00:41:09] That suggests Calyptrophora [00:41:23] Calyptrophora [00:41:36] thank you for the zoom!! [00:42:05] The basal sclerite "spiny" is usually sticking out in the genus when the polyps are contracted [00:43:16] LAT : 28.879182 , LON : -177.869013 , DEPTH : 2035.3699 m, TEMP : 1.80726 C, SAL : 34.62066 PSU, DO : 2.92041 mg/l, TURBIDITY : 0.0611 FTU [00:43:27] one branch just broken off to the left [00:43:48] floated to the left, I mean [00:44:33] Shiny manganese crusts! I actually have an answer that came from some USGS colleagues [00:44:43] WAIT REALLY [00:44:56] They can be polished to a shine by the current [00:45:00] Which is higher around here [00:45:02] val rock from bottom? may be some loose here but not sure if helpful [00:45:05] WHAT [00:45:15] lindasunderland leaves the room [00:45:23] Sure, a rock from here could be interesting [00:46:44] ok we can probably get some from the lee. not sure if it will be same composition as the rock that weathered away, but maybe a clue? [00:46:52] will do that after we see the top [00:47:14] we can see large bushy colony [00:48:16] LAT : 28.879176 , LON : -177.868922 , DEPTH : 2031.6461 m, TEMP : 1.83433 C, SAL : 34.61769 PSU, DO : 2.86151 mg/l, TURBIDITY : 0.0549 FTU [00:48:24] just copying here 035 strike of dike [00:48:46] thanks! Yes, that aligns with the big linear feature running through the summit region [00:48:51] Very interesting [00:49:03] It's one of my favorite uses of an ROV!

[00:55:38] christophermah leaves the room [00:58:05] wow. those Hippasteria are more common here [00:58:17] LAT : 28.879238 , LON : -177.868976 , DEPTH : 2033.4165 m, TEMP : 1.84 C, SAL : 34.61713 PSU, DO : 2.79708 mg/l, TURBIDITY : 0.0611 FTU [01:01:25] christophermah leaves the room [01:02:00] Steve we have 3 niskins left [01:02:17] Val we are eyeing the large rock at the base of the dike [01:02:22] waiting on tether [01:02:50] nvm we are going for it now!

[01:03:44] ah yeah, poke never hurts [01:04:22] Well, sometimes the seamounts don't give up their rocks. We try our best [01:04:35] too big [01:04:37] yeah [01:05:07] good plan [01:05:23] christophermah leaves the room [01:05:33] I swear that boulder was a large cobble five minutes ago [01:06:06] that's what we said! [01:06:39] unfavorable grain size distribution for geochemistry here [01:07:39] If we do see a good rock before end of dive, one last grab would be great if possible. But this was totally awesome [01:08:17] LAT : 28.87945 , LON : -177.869031 , DEPTH : 2032.0972 m, TEMP : 1.85613 C, SAL : 34.61432 PSU, DO : 2.80238 mg/l, TURBIDITY : 0.0549 FTU [01:08:30] Who planned this track?

If there are any burrowing polychaetes I would recommend leaving them in the coral so they don't break apart [01:13:31] ROVs are so versatile.

The seamount morphology is closer to what I would expect for Hawaiian (hypothesized), but the rocks are crusty enough that I'm not confident on approximate age [20:01:07] man, vid isn't happy today [20:01:49] so sorry about the video... internet unhappy today [20:01:55] we're working on it but not sure how it will be [20:01:59] No apologies needed!

[20:03:47] There will be something around here [20:03:55] maybe dead center? [20:03:57] christophermah leaves the room [20:04:36] going for center [20:04:48] Val, I suggested this site because of the terrace we are just below. It seemed to be too deep for a relatively small Hawaiian seamount. Also, I don't see similar terraces on the two sister seamounts to the east. Finally, the depth of the terrace is consistent with other Cretacious guyot summit depths around here.

I try to use FeMn crust thickness as a proxy, but that's not really reliable. Rocks can be exposed tends of millions of years after they were emplaced, and I'm not even sure how constant the crustal growth rates are. The absolute dating methods are key, along with the "flavor" of mantle that melted to form these [20:08:44] Yeah, Kira Mizell and Amy Gartman are the folks to ask about FeMn [20:09:57] Well, hopefully they will be able to pry a rock free so we can find out for sure.

Probably a new famility that needs to be defined [20:45:42] LAT : 28.780003 , LON : -179.126837 , DEPTH : 1445.5323 m, TEMP : 2.61465 C, SAL : 34.52021 PSU, DO : 1.55246 mg/l, TURBIDITY : 0.0672 FTU [20:46:11] THe initial description by Operesko & Wagner didn't include DNA assignment [20:46:14] under the sponge looks like a soft coral [20:46:30] Anthomastus or Heteropolypus? [20:47:14] thallasometrid crinoid I think. Prehensile cirri [20:47:19] yes. near one another [20:48:00] feather star [20:48:05] no worries. happy to see the enthuriasm about poop! [20:48:23]
