[15:46:07] Hexactinellida [15:47:06] Chrysogorgiidae gorgonian behind [15:47:38] looks like maybe a shrimp inside [15:47:43] brittle star at the base [15:50:19] Morning y'all! Yes this is a Hexactinellid in the family Euplectellidae, likely Regadrella genus [15:50:25] LAT : 29.112205 , LON : -79.445828 , DEPTH : 750.7035 m, TEMP : 8.25418 C, SAL : 35.1425 PSU, DO : 4.90525 mg/l [15:50:36] Wow, didn't realize how delayed I am... [15:50:53] some kind of fish [15:53:31] Alexis Weinnig leaves the room [15:55:25] LAT : 29.112127 , LON : -79.445732 , DEPTH : 747.4827 m, TEMP : 8.2532 C, SAL : 35.14253 PSU, DO : 4.91191 mg/l [15:55:39] Hi Nolan! [15:56:14] @Asako Hello! How are you doing? [15:56:51] @Nolan almost sleeping! [15:57:37] @Asako I am sure! Its great to see you in the chat! I hope you are doing very well too! [15:57:48] sponge, not a seastar [15:59:57] @Nolan you too! I'm glad to join here again:) [16:00:25] Could you zoom in on the substrate on the mound crest to see if small organisms are any more abundant here? [16:00:27] LAT : 29.112048 , LON : -79.445736 , DEPTH : 744.1318 m, TEMP : 8.2603 C, SAL : 35.14326 PSU, DO : 4.90348 mg/l [16:01:56] Looks as if the slope runs upward ahead of D2. We may still be on the downcurrent side of the crest. [16:04:18] lots of brittle stars [16:05:26] LAT : 29.111981 , LON : -79.445634 , DEPTH : 748.6962 m, TEMP : 8.26015 C, SAL : 35.14374 PSU, DO : 4.89524 mg/l [16:10:27] LAT : 29.111982 , LON : -79.445628 , DEPTH : 748.8179 m, TEMP : 8.26314 C, SAL : 35.14315 PSU, DO : 4.88551 mg/l [16:12:46] @WatchLeads Here's an idea for an next eventlog update: talk about the new slurp gun, how the TGFOE engineered it, how it stores samples, and how you recover those samples. [16:13:57] @nolanbarrett: we will be posting a mission log on the suction sampler monday if you are interested [16:15:12] @Adrienne Thats awesome, thank you! I remember the ROV team talking about it over the last several ROV expeditions, so I am just so excited to have it finally installed and working! [16:15:27] LAT : 29.111992 , LON : -79.445643 , DEPTH : 748.9215 m, TEMP : 8.26648 C, SAL : 35.14365 PSU, DO : 4.84395 mg/l [16:18:32] Thanks very much.

[16:24:11] Speaking of ASPIRE, if we see another Aphrocallistes (hopefully with associates) we should collect it since it is on the ASPIRE sponge list. I will also keep my eye out for other APSIRE sponges Vasella pourtulessi, Geodia sp., and Pheronema sp. [16:25:28] LAT : 29.111833 , LON : -79.44582 , DEPTH : 753.3961 m, TEMP : 8.27358 C, SAL : 35.1439 PSU, DO : 4.87987 mg/l [16:26:09] And, any stalked crinoid--sea lily--should be collected. We know almost nothing of those animals from the area between the Bahamas and New England. [16:29:47] definitely looks like a seastar [16:30:08] Off left looked like a different paler crinoid with more than 5 arms. [16:30:29] LAT : 29.111747 , LON : -79.44583 , DEPTH : 758.2372 m, TEMP : 8.27297 C, SAL : 35.14435 PSU, DO : 4.89843 mg/l [16:30:47] Alexis Weinnig leaves the room [16:31:09] The dead coral rubble is almost covered with those agglutinating foraminiferans. [16:32:31] Im going to say in the family ophidiasteridae [16:35:29] LAT : 29.111582 , LON : -79.445965 , DEPTH : 757.5263 m, TEMP : 8.27456 C, SAL : 35.14481 PSU, DO : 4.89054 mg/l [16:36:21] Blue sponge - Desmacellidae. [16:36:48] @Chuck Agreed [16:37:33] @Tina Hi Tina! Welcome, we missed you! [16:37:43] Happy to join you. [16:38:15] oh, nolan, sorry for it [16:38:29] @Tina Hi!! [16:39:17] Hi Tina! [16:39:56] Echionothurid [16:40:30] LAT : 29.111437 , LON : -79.446027 , DEPTH : 751.4454 m, TEMP : 8.2723 C, SAL : 35.14436 PSU, DO : 4.89229 mg/l [16:40:39] Goniasteridae [16:41:31] Alexis Weinnig leaves the room [16:41:35] Plinthaster or Spheriodiscus? [16:41:56] for some reason in Australia they call it biscuit-star [16:42:10] if it was Bathypathes? [16:42:38] @Tina They american cookies=Australian/English bisuits [16:44:03] The stylasterid with the monoplanar colony form and thick branches was likely either Pliobothrus or Distichopora. [16:44:51] ... disgusting stars [16:45:30] LAT : 29.111304 , LON : -79.445995 , DEPTH : 747.5108 m, TEMP : 8.2723 C, SAL : 35.14475 PSU, DO : 4.88948 mg/l [16:45:35] mashkoormalik leaves the room [16:45:54] something interesting? [16:46:28] Have to sign off for a while. Great work you are all doing! [16:46:39] Thanks Chuck! [16:46:50] how more ours we have on bottom? [16:48:09] @Chuck Have a great day! [16:48:22] I have a question to a pilot. How long it usually take to get 1000m? [16:48:30] charlesmessing leaves the room [16:49:18] Crinoids with five arms, what Chuck calls them? [16:49:19] We have moved antoher 100 meters [16:49:23] 400 total [16:50:11] thx [16:50:31] LAT : 29.111244 , LON : -79.446057 , DEPTH : 750.7108 m, TEMP : 8.2741 C, SAL : 35.14499 PSU, DO : 4.8877 mg/l [16:53:14] Tina: Pentametocrinus atlanticus [16:55:03] thanks, tara!

[16:59:39] Alexis Weinnig leaves the room [17:00:29] mostly soft sediment?

[17:09:55] Alexis Weinnig leaves the room [17:10:33] LAT : 29.110726 , LON : -79.446143 , DEPTH : 763.1942 m, TEMP : 8.27523 C, SAL : 35.14467 PSU, DO : 4.88487 mg/l [17:10:46] I think it is specific, if not genus [17:10:51] I have never seen a hexactinellid morph quite like that before... [17:10:54] polyps I meen [17:11:17] possibly Keratoisis [17:11:25] nice hydrozoans. [17:11:39] Too bad the current is so high that we cannot collect either coral or sponge [17:12:21] fluffy thing is bamboo? [17:12:32] @tina yeah I think so [17:14:05] Echinothurid [17:14:52] Chrysogorgid possibly Metallogorgia [17:14:57] Could this be metallogorgia? [17:15:13] @nolan, do not think so [17:15:33] LAT : 29.110712 , LON : -79.446178 , DEPTH : 762.55 m, TEMP : 8.27703 C, SAL : 35.14418 PSU, DO : 4.8921 mg/l [17:15:41] I thought we were looking down from the top [17:16:42] nice bamboo [17:16:46] Leiopathes [17:16:50] Leiopathes [17:16:56] my guess [17:17:38] it is a genus that can be old [17:18:03] Also indicates that the current has been consistent for a long time [17:18:39] another black coral at the base of large one [17:19:03] not good condition [17:19:21] Crinoids have at least 8 arems [17:20:02] Does anyone know if the tips of squat lobster legs are hooks or claws? [17:20:34] LAT : 29.110767 , LON : -79.446301 , DEPTH : 763.2268 m, TEMP : 8.27554 C, SAL : 35.14471 PSU, DO : 4.88824 mg/l [17:20:49] Crinoid has maybe 10 arms [17:21:07] apparently it was damaged some years ago and after all these animals were able to settle [17:22:40] Bathypathes, or [17:22:44] @WatchLeads great eyes! [17:22:50] Dennis would put Telopathes [17:23:12] there is another small colony [17:23:47] mashkoormalik leaves the room [17:24:09] Scorpinidae [17:25:19] Wrong spelling, this is correct: Scorpaenidae [17:25:34] LAT : 29.11074 , LON : -79.446232 , DEPTH : 763.2289 m, TEMP : 8.27554 C, SAL : 35.14435 PSU, DO : 4.88637 mg/l [17:26:17] One easily distinguishing characteristic is the spines on the operculum. They like to be ambush predators, note the mouth facing into the current. [17:28:36] urchin munching [17:28:43] if that urchi eat sargassum?

[17:31:31] many Sargassum today? [17:31:45] MIDWATER!!!!! [17:31:49] @Tina Not so much [17:32:10] @Mike We can finally collect midwater organisms with the slurp! [17:32:14] a few sargassum today - about 3 [17:32:38] if you collected something with slurp already? [17:33:34] @Tina Yes, the crinoid for Chuck [17:33:38] Yes, we collected a squat lobster yesterday and the crinoid earlier on this dive [17:34:50] great! [17:35:28] @Tina Yes, the pilots are getting a lot of good practice!

[17:36:06] for me too [17:37:07] @Amy Could could you please tell the audience what a pteropod is and why they are important, especially to geologists? [17:37:12] I have seen many dead pteropods in my life. it was not a mistake))) [17:37:21] Can we get estimate on remaining bottom time? [17:39:24] another Leiopathes [17:39:56] even two [17:40:14] Stichopathes of some kind [17:40:36] LAT : 29.110397 , LON : -79.446253 , DEPTH : 759.0333 m, TEMP : 8.27636 C, SAL : 35.14411 PSU, DO : 4.88782 mg/l [17:40:54] left coral [17:40:57] completed another 100 meters [17:41:15] Yes black coral unidentified.
