Here we are encountering abundant and diverse fishes. Earlier dives had few fishes. [14:45:22] I didn't mean to suggest the small size was a reason not to collect. Just saying it is small!

[14:46:07] leswatling leaves the room [14:46:07] Yes, this is what Chris M. had pointed out [14:46:18] chris mah told something about small urchins with baldish top [14:46:52] Yes, I went back and looked at what we had seen, and they were very similar to this, maybe a little different - long arms around the radius and short or no arms on top [14:47:47] he called it by name?

[14:49:10] just need to screenshot it [14:49:44] @Ken: I wonder if as we move west we are getting into Gulf Stream influence and greater productivity...? [14:51:43] scott - all the fishes we have encountered are benthic infauna and epifauna munchers. They need sediment to forage within on on. And that sediment needs to be richly provided with particulate food for benthos. So, I think you are right. Fish presence here suggests a more productive overlying watermass. [14:52:20] All those baby sponges suggest the same thing [14:53:11] LAT : 36.347755 , LON : -59.118794 , DEPTH : 2127.3426 m, TEMP : 3.46398 C, SAL : 34.95226 PSU, DO : 8.26384 mg/l [14:55:27] noellehelder leaves the room [14:55:43] If you selected one species of common glass sponge, then measured height of each specimen, then plotted a length frequency curve, you could possibly determine how fast that species grows. If curve represents a wide range of size classes, rapid growth is likely. But if there is dominance of an ultimate final size, slow growth to that ultimate size is more probable. Typical r and K thing. [14:56:38] @Ken: we'd have to also select a species that has a predictable growth form, not one of the amorphous growers. [14:57:27] You will find that other folks would interpret this size thing in just the opposite fashion. I am basing this on my experience with fish sizes. And yes, I was thinking of one of the tubular glass sponges that would be more readily measured with lasers.

[14:59:41] Tyler showed that with brittle stars long ago. [15:00:09] Often timed with reproduction - they put on size to get big enough to develop gametes, and then utilize growth energy for reproduction from thereon.

[15:02:17] I see it in its new home in canister 5 [15:03:00] OE ROV missions are heavily focused on imaging and collecting sessile epifaunal megafauna. Might be worth considering a mission that suction samples the sediment for topside sieving and identification of the macrofaunal benthos contained in the sediment drape atop the volcanic understructure.

[15:36:22] @Scott, I thought you had mentioned once that there were a few specimens we had seen that had this no trident look [15:36:51] @Les: yes, but I don't think they were nodal branchers. [15:36:56] where do you need the sample? [15:37:00] it has no polyps at the stalk? [15:37:21] yeah, agree, higher up, but lower down looks like maybe the branching point was reinforced or something to push the branch point away from the node [15:37:51] noellehelder leaves the room [15:38:05] Just got disconnected from the call.

[15:39:45] What I suggested was at least 2 nodes, preferably 3. So cutting along thta lower branch 3 "raised" branches in. [15:40:30] @Scott - huh. Odd. Copy on the branching [15:40:34] Should cut very easily. [15:41:44] from the look of the polyps i am wondering if those whips we saw earlier were just early stages of this thing. they weren't too tall.... [15:42:10] That looks great where they are headed.

[15:46:57] kensulak leaves the room [15:47:19] @Les: the only other NES corals that have a remotely similar branch pattern are in D1 clade (so clearly internodal branching) and a J clade, that doesn't really look like a candelabrum.
