(2006, 2009) for age and growth of gold corals as microns per year, hence big colonies are on the order of 1000's of year old.

[19:44:04] deborahglickson leaves the room [19:44:38] wow, nice crinoids [19:44:55] Proisocrinus ruberimus [19:45:08] maybe [19:46:11] I suspect when we get a look at the bamboo coral that it will have nodal branching = Isidella like (clade I1) [19:46:29] LAT :-6.49180, LON : -173.58340, DEPTH : 2105.7183m, TEMP : 2.00571C, SAL : 34.65184 PSU, DO : 4.03674 mg/L [19:48:04] re: tomorrow's dive - maybe just shooch that whole dive track over so that it ends on the summit. I don't think the backscatter was significantly different along that steep slope, and I have found that backscatter data are less reliable on a slope like that. 600 m track length seems doable, as long as it ends at the top [19:48:28] thanks erik-i'll look it over with derek while he still has the map up [19:48:56] randirotjan leaves the room: Replaced by new connection [19:49:04] Great lighting... [19:49:34] And there is why we look! [19:49:43] Looks internodal... [19:49:47] branching [19:49:52] agree @Erik and Amanda. Think we should design it to hit the top of the summit tomorrow. [19:49:55] one more branch below [19:50:14] no apparent associates on this bamboo [19:50:15] So back to the drawing board on this ID [19:50:28] I think it is branching just distal to the node [19:51:06] Cursed bamboo corals... [19:51:18] tim/erik-ok, looks like we have a possible plan, maybe [19:51:28] But the tiy branch is internode [19:51:32] LAT :-6.49175, LON : -173.58337, DEPTH : 2105.0634m, TEMP : 2.00793C, SAL : 34.67515 PSU, DO : 3.96103 mg/L [19:51:34] *tiny [19:51:43] Thanks - beautiful steady images [19:51:48] @amanda - sounds good. You guys haven't steered us wrong yet! [19:51:54] As usual, kudos to the whole team [19:52:25] @Erik at least not anything we haven't told you about...:P [19:52:35] Hola! [19:52:43] Hi Peter [19:53:07] everything's great, as far as I know. Let's just keep it that way :) [19:53:31] no apparent associates on this black coral.... [19:54:19] Or Heteropathes [19:54:35] My computer froze there when I was typing about the black coral [19:55:07] yes Heteropathes. Amanda started me saying Hexapathes now I'm confused... [19:55:22] boo hoo [19:55:26] That Amanda...

Large septa extending beyond the calyx rim [19:59:36] These are some bg blocks of rock.

[20:04:55] scott: agree, not being sarcastic, for a change [20:05:26] looked like a chrysogorgia a little upslope.... [20:05:46] .....chrysogorgid [20:06:04] Is that a slope crusted over with Mn?

[20:14:19] Tubulariidae like [20:14:21] don't remember seeing a "stalk" like this with a solitary hydroid [20:15:07] tubulariidae have perisarc (external "tubes") [20:15:39] unlike corymorphids [20:16:21] saw several similar to this in A.

We have some dead air to fill? [20:37:33] thanks! [20:39:17] Pleurogorgia! [20:41:11] looks like they are in a fissure [20:41:35] LAT :-6.49160, LON : -173.58314, DEPTH : 2052.0869m, TEMP : 2.16351C, SAL : 34.64229 PSU, DO : 3.83932 mg/L [20:42:06] we've got a bunch of neighborhood kids over, so i'm not sure I can call in without a LOT of background noise :) [20:42:23] Randi did great! [20:43:08] thanks - distracted - can hear my son crying upstairs. But happy to do that again a few times today (last dive) - can add some other perspective throughout the day. You guys are AMAZING! Talking the whole time! [20:46:24] Yes!

[20:47:56] you can't make me say it [20:48:01] any ideas on branching chryso? also pleurogorgia? [20:48:21] I don't think Pleurogorgia, which are dexcribed as planar [20:48:34] no associates :-(, but interesting [20:48:39] I'd chalk it up to one of the many, many Chrysogorgia species [20:48:54] But no idea which one. [20:50:00] we have only seen barnacles and an anemone on "Pleurogoriga" (only on bare skeleton)....Carondelet or here.

[20:52:11] Unfortunately I must leave for a couple of hours. Domestic duties call.
