[10:30:02] <danielwagner> We will have a delayed deployment for today's Dive 7. We are anticipating launching the ROV at 1215 EDT and reaching the seafloor at 400 m at ~~1230 EDT
[10:30:33] <danielwagner> Also note that today's dive will be inside Oceanographer Canyon, and not Musnon Canyon as originally scheduled.

[17:33:50] <taraluke> Hi Megan, that was me (on the call), but a student came in and I disconnected.  Sorry!
[17:34:13] <scottfrance> I just tried calling again and I get a "Call cannot be connected" message.
[17:34:53] <taraluke> It doesn't like you today, Scott
[17:34:57] <meaganputts> no worries, Tara. 
[17:35:00] <scottfrance> If I called in I would tell you my first OER expedition was in 2001 and we dove in Oceanographer Canyon (using Alvin)
[17:35:08] <jeffreyobelcz> Informed video and they're on it Scott.
[17:35:50] <scottfrance> @Tara: you didn't get the weee-weee-weee FAX sound when calling in? [that is a serious question]

[17:38:57] <scottfrance> Apologies: a student came in just as Daniel was beginning to speak, so I missed what he said. Was there an important operational/scheduling message delivered?
[17:40:24] <jeffreyobelcz> Scott, just that we'll make a decision tonight on Dorian whether we're heading in for the weekend

[18:18:51] <scottfrance> @Jeff: interesting. I wonder if it is a call center issue related to hurricane power outages, i.e. how calls from the south are being routed.

[19:44:47] <jeffreyobelcz> Tara that's possible but looked erosional to me. Just not sure why it took that shape. Most likely explanation is probably random variance of massive (no bedding, no preferential erosion) sediments.
[19:44:56] <nolanbarrett> I thought the large brancher could have been a primnoid, I was seeing texture on the polyps.

[19:53:24] <nolanbarrett> How would this have deposited/formed?
[19:54:22] <jeffreyobelcz> Need to know the material before I can guess.
[19:54:59] <nolanbarrett> @Jeff Good point.
[19:57:13] <jasonchaytor> These are mudstones/claystones, largely dewatered by compaction, but lacking cements that would otherwise bind the sediment particles. They are predominantly formed via pelagic/hemipelagic deposition and downslope sediment transport events.  The "rocks" here are likely Miocene to Pliocene age, but I could be wrong because I don't have a good sense of your actual position

[20:09:32] <danielwagner> Hurricane Dorian is now forecast to start moving northwards, with storm to hurricane force winds predicted to arrive in our expedition’s operating area by Friday 9/6. Therefore, we will pull into port in Rhode Island tomorrow to weather the storm. The plan is to get back underway to finish the rest of the expedition as soon as conditions are safe, which might be as early as Saturday. However, given the long transit distances, we will definitely not dive on Thursday, Friday or Saturday (9/5-9/7). I will pass on more information, including a revised schedule for the remainder of the expedition, as soon as we learn more.   Thanks so much for your continued support of our expedition, and please do not hesitate to reach out if you have any questions.
