04/21/2014,01:35:40,kelleyelliott,Update from the NOAA Ship Okeanos Explorer. We are currently conducting overnight mapping operations as we transit to Bryant Canyon where Dive 09 of the expedition will be conducted tomorrow morning. The dive is expected to start at about 2560m deep and will transit up the east wall of the canyon to characterize benthic habitats and explore for deep sea coral and chemo communities, and validate/groundtruth deep sea coral model predictions for bamboo corals.  Weather permitting, the ROV will be launched at 0830 (Central Daylight Time) and we expect to arrive on the seafloor around 1000.  We will host a pre-dive briefing via conference call at 0930 CDT during the ROV descent to discuss the dive and objectives.    04/21/2014,01:35:54,kelleyelliott,Join us by dialing 1-866-617-5860, passcode: 1233796 and tuning into the video online at: http://oceanexplorer.noaa.gov/okeanos/media/exstream/exstream_04.html 04/21/2014,01:36:40,kelleyelliott,Reminder that a high resolution version of the main ROV camera feed will be made available to contributing scientists during the ROV dives here: http://oceanexplorer.noaa.gov/okeanos/media/exstream/exstream-full-res.html 04/21/2014,13:40:55,danwarren,Good Morning everyone. I will be lurking in the sidelines today off and on when I am not dealing with other wrok priorities. Just in case of an unanticipated discovery :-) 04/21/2014,14:01:48,okeanosexplorer,Update from the NOAA Ship Okeanos Explorer: the current time on board is 0900 and our location is 25o 55' 09.119" N, 91o 57' 385" W. The ship is currently on station preparing the ROV for deployment at Bryant Canyon. The objective of today's dive is to investigate benthic habitats in the canyons, including looking for deep sea corals. The ROV was deployed at 0830 and should arrive on bottom at about 2550 m at about 1000. We will have a dive briefing via telecon at 0930. Please join us by dialing: 1-866-617-5860, passcode: 1233796 and tuning into the video online at: http://oceanexplorer.noaa.gov/okeanos/media/exstream/exstream_04.html 04/21/2014,14:14:30,briankinlan,Good morning everyone. Looking forward to a great dive today. 04/21/2014,14:21:14,Jamie Austin,Good morning everyone. Jamie Austin here. We will be diving on a ridge on the east side of Bryant Canyon today, in water depths of ~2600-2400 m. Our vehicles are in the water, passing a depth of 1525 m. We will be on the phone in about 10 minutes. Beautiful weather, minimal heave - hopefully good comms. 04/21/2014,14:29:00,kelleyelliott,Reminder to PLEASE MUTE YOUR PHONE when you're not speaking on the telecon.

The current time is 1840 Central. We are currently conducting overnight mapping operations on the Sigsbee Escarpment, east of Bryant Canyon. Tomorrow we will dive at "Bryant Canyon Deep", transecting up the western wall of the canyon starting about 2800m deep to search for deep-sea corals. During our descent to the seafloor, we will investigate the water column, conducting 15-minute transects at 800, 900, 1000, 1100 and 1200 m to identify animals that may be prey for deep-diving whales. Weather permitting, the ROV will be launched at 0830 (Central Daylight Time) and we expect to arrive at 800m to begin water column transects at approximately 0900. We expect to arrive on the seafloor to commence the benthic portion of the dive between 1100 and 1130. We will host a pre-dive briefing via conference call at 0845 CDT during the ROV descent to discuss the dive and objectives.
