[21:39:16] Interesting. That is likely sediment bound up by mucus from the peduncle making it look like a tube [21:39:28] The brown stripe in the polyp is the pharynx [21:40:34] similar to ones seen on previous Okeanos trip!

[22:09:44] We're trying to make tracks to get to a scarp face before the end of the dive - we went in late today - so they did all they could with that boulder [22:11:03] @Rhian: you are probably right, and I'm not criticizing. But since we didn't get a look at the colony (it was the first one we saw as we came in) I like to get something into the chat for later video annotation.

[22:14:02] With these short dives Asako we'd not get far if we zoomed on every rock.....so it's a trade off we have to make and the objective of this dive was to make it to the scarp [22:14:08] WE have 45 minutes left of the dive [22:14:10] To Bobby's question, I don't know what that spider looking thing was! Maybe a juvenile star? [22:14:20] ChristinaConrath leaves the room [22:14:30] Early analysis of the 1946 earthquake assigned magnitudes of 7.1 to 7.4, relatively small for the large tsunami that was generated.

I mentioned when we recognized some different shape colonies on the same rock :) [22:15:35] rattail [22:15:42] and crab [22:15:55] @asako - understood - but again we were moving, zooming on each shape was not possible [22:16:45] LAT : 53.507115 , LON : -164.16964 , DEPTH : 2745.0867 m, TEMP : 1.61249 C, SAL : 34.64153 PSU, DO : 3.17755 mg/l, TURBIDITY : 1.1294 FTU [22:17:15] dhugallindsay leaves the room [22:17:54] zoom on fish?
