[16:22:41] <michaelvecchione> Muusoctopus (used to be Benthoctopus)
[16:23:06] <michaelvecchione> nice video

[16:43:40] <enriquesalgado> Octopus under wreck
[16:44:41] <divaamon> Hey folks. I'm not on the call but lots of wood-fall fauna here sheltering/feeding. Munidopsis squat lobsters, evidence of lots of boring - not sure by what yet
[16:51:03] <danielwagner> Thanks Diva!
[16:51:33] divaamon leaves the room
[16:52:22] <divaamon> No probs. Some polychaetes in sediment close to the wreck too. Maybe chaetopterids.
[16:52:54] <divaamon> They don't look like siboglinids but I could be wrong.
[16:53:49] jimmasterson leaves the room
[16:54:26] <melaniedamour> Diva, wood-boring Xylophagainae perhaps? I've had a hard time finding info on confirmed pholad species in the deepwater Gulf.
[16:59:01] <divaamon> @melanie: we need to get a really close up shot on some wood. I would assume Xylophagainae unless most of the boring occured in shallow waters. Then would be Teredinidae. Also it could be limpets/gastropods too which carve out shallow depressions.
[16:59:17] <divaamon> In a nutshell, we need to get a good zoom to get an idea :)
[16:59:59] <nolanbarrett> @Diva It would be quite interesting to see!
[17:00:06] <divaamon> a better idea, I should have said.
[17:00:40] <meganmcculler> There's an octopus in a hole!
[17:00:58] <meganmcculler> pan left
[17:01:05] <melaniedamour> @Diva, I stumbled upon your dissertation while doing some wood degradation research, btw. :)
[17:01:24] <nolanbarrett> @Megan Cephalapod Friday?!?!
[17:01:29] <meganmcculler> you can see the suckers
[17:02:00] <nolanbarrett> @Megan Hurray!
[17:02:20] <meganmcculler> aw man I wasn't able to get a screen shot
[17:03:00] <nolanbarrett> @megan Oh, I forgot there was one crawling along the sea floor earlier. So its is definitely Cephalopod Friday!
[17:03:43] <meganmcculler> @nolan oh cool! I just tuned in and got really excited :)
[17:04:27] <nolanbarrett> @Megan I'm excited too! Unfortunately, Im running to and from my lab. But ill try to keep up with the chat.
[17:05:16] michaelvecchione leaves the room
[17:05:18] <danielwarren> are the lasers on?
[17:06:02] <danielwarren> can we zoom to base of the fastener/pipe
[17:06:39] <divaamon> @melanie: you definitely don't want to read that!
[17:11:21] <melaniedamour> @Diva - Ha! On the contrary, I found it quite informative! I'm intrigued by the deepwater wood falls as "stepping stones" hypothesis but noticed that historic shipwrecks haven't really been included despite providing a substantial amount of wood substrate.
[17:13:37] <danielwarren> @Diva and Melanie  Mel I think you and I have had past discussions about how organisms like squat lobsters are impacting preservation on deepwater wooden wrecks.
[17:14:26] <meganmcculler> @nolan I'm wearing my octopus shirt today so yesss
[17:15:25] <danielwarren> That looks like iron
[17:20:16] <melaniedamour> @Diva, it looks like the wood-boring tunnels are along the wood grain, not so much perpendicular.
[17:25:01] laurenjackson leaves the room
[17:29:29] <divaamon> @melanie: you are very correct about the shipwrecks. Very few mentions in the literature on shipwrecks bring wood falls. I stepped away for a bit so I didnt get to see! Will keep watching for more borings.
[17:30:10] <divaamon> @danielwarren: there is one species of Munidopsis that is known to eat wood so likley they do have an impact
[17:32:01] <divaamon> Those tube worms are either sabellids or serpulids
[17:33:16] enriquesalgado leaves the room
[17:33:20] <danielwarren> @divaamon I have read one article detailing study from Pacific region but that is the only reference I have on Munidopsis eating wood.
[17:36:42] <divaamon> @daniel: That's the one I meant!
[17:38:12] meganmcculler leaves the room
[17:43:27] <danielwarren> @divaamon That is the article I read that started me thinking about how the impact of organisms on wooden shipwreck preservation has been underestimated
[17:45:25] <divaamon> @danielwarren: clearly there need to be more studies on food sources in the deep sea!
[17:46:27] <danielwarren> @divaamon I couldn't agree more.
[17:47:18] katerose leaves the room
[17:54:38] <divaamon> Hey Dan or Adam, any chance we could collect a Munidopsis?
[17:54:46] <divaamon> after the mapping obv.
[17:55:23] <danielwagner> potentially, we will have some time.

[18:22:52] <markbenfield> That 'viperfish' was a slickhead family Alepocephalidae
[18:31:03] <markbenfield> It would be very useful to have digital stills of any plastic debris found on the seafloor.
[18:31:55] divaamon leaves the room
[18:36:33] <danielwagner> yes mark, and periodic still are being collected
[18:37:05] <markbenfield> Great

[19:22:53] <heatherjudkins> HI guys!  Heather J/ here .  missed the id Mike V gave?  What was it?  Benthoctopus?
[19:23:49] <heatherjudkins> It's looking like it's trying camoflauge with the sediment....
[19:24:03] <danielwagner> Muusoctopus (which used to be Benthoctopus)
[19:24:16] <heatherjudkins> Stay with it, if possible
[19:24:27] <heatherjudkins> Yahoo, Mike!
[19:26:16] <heatherjudkins> I would think burrowing but he's not getting underneath the sediment....
[19:26:40] <amybowman> I still have live stream from shore
[19:26:47] <heatherjudkins> I am still on live
[19:28:17] <heatherjudkins> Thanks, you guys!  Awesome footage for Mike and I to check out in detail and discuss with our colleagues...

[19:53:36] <laurenjackson> could that mark in the sediment be from a beaked whale ?
[19:55:45] <laurenjackson> can you type the name of that sea star in the chat, so I can add it to sea scribe please
[20:04:40] andrewshuler leaves the room
[20:09:41]  jessicarobinson leaves the room
[20:17:58] <leswatling> @lauren, agree the mark was very much like beaked whale marks we have seen elsewhere in the Altantic
[20:22:53] <markbenfield> That was a halosaur but not a lizardfish. Lizardfish are family Synodontidae.
[20:23:26] <leswatling> I see and understand there is no nav data. I cannot run audio at the moment so could someone type depth into chat?
[20:25:05] <danielwagner> 1880 m
[20:25:17] <leswatling> Thanks @Dan
[20:26:01] <leswatling> That is pretty deep but not out of the realm of possibility for beaked whale feeding mark.
