04/20/2014,13:21:18,okeanosexplorer,Update from the NOAA Ship Okeanos Explorer: the current time on board is 0830 and our location is 26d 26' 17.003" N, 93d 19' 329" W. The ship is currently on station preparing the ROV for deployment at Keathley Canyon. The objective of today's dive is to investigate benthic habitats in the canyons, including looking for brine flows and deep sea corals. We are set for an on time deployment. The ROV will be deployed at 0830 and should arrive on bottom at about 2623 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  
04/20/2014,13:39:08,kelleyelliott,Good morning and Happy Easter everyone! The ROV has been deployed and is descending to the seafloor at 2620m depth for the start of Dive 08 in Keathley Canyon. Today we will climb the east wall of the canyon at an area likely to host natural fluid seeps. The ROV should arrive on bottom 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

04/20/2014,14:46:10,okeanosexplorer,  Good morning everyone! This is Stephanie Farrington the Biological Co-Science Lead aboard the Okeanos Explorer. We are trying to make the data coming from this event log easier to process and more useful. We are asking for a slight change to the SOP. If, before you identify or make a comment about the fauna or habitat, you could start your entry with a Carrot (>). All other comments can be kept as normal.  We are trying to find an easy way to filter identification/habitat data from other conversations.  I will be reminding everyone throughout the dives. The Data Management Team aboard the Okeanos Explorer thanks you for your cooperation.

04/20/2014,14:54:34,danwarren,Good morning everyone.  Bill we have set down similar experiments in several wrecks around the gulf at various depths.  The earliers were set on the U-166 site in 2003.  We found that in about 6 years most of the wood on the U-166 platforms was gone.  We recently recovered one of these platforms and it is currently being analyzed.  We hope to recover the experiments from the wooden hull wrecks in the upcoming years. 
04/20/2014,14:54:34,okeanosexplorer,26 17.3222N 93 19.3159 W 2456 m 4.30deg 34.96PSU
04/20/2014,14:55:44,amandademopoulos,did you put the experiments in bioboxes, Dan?
04/20/2014,14:56:03,okeanosexplorer,2500 m
04/20/2014,14:56:39,amandademopoulos,hi front row!
04/20/2014,14:57:35,Bill Kiene,Interesting Dan.  I'll be interested in the results.  So far the different wood types seem to be responding very differently.  Fascinating how the critters find and establish on the wood.
04/20/2014,14:57:46,okeanosexplorer,between WP 1 and WP 2, Avg Slope is 11 deg. between WP2 and WP 3 the Avg slope is 2 deg. between WP 3 and WP 4, Avg slope is 11 deg.  We expect sea floor at 2640 m.
04/20/2014,14:58:05,danwarren,Amanda, the samples were placed on platfoms designed by Roy Cullimore and Lori Johnston of Droycon BioConcepts.  They have been working on studying the preservation of the wrecks since we first explored the U-166 in 2003.
04/20/2014,14:58:59,amandademopoulos,so how were they recovered? or are they still in situe
04/20/2014,14:59:00,amandademopoulos,in situ
04/20/2014,14:59:38,amandademopoulos,or is that proprietary information :)
04/20/2014,15:00:33,danwarren,When we went to U-166 in 2010 those were the platforms we looked at on the stern and bow.  You were out there on that cruise.  They were designed to be recovered with an ROV and placed in the recovery basket.  They were able to bring one up and the other is still on the site.  
04/20/2014,15:01:05,amandademopoulos,all a blur :) but yes i thought that they were "easily" recovered
04/20/2014,15:01:19,danwarren,They were brought up with very little disturbance to the organisms and growths on the platforms.

04/20/2014,15:02:08,amandademopoulos,did anyone get a good zoom on the carpet of "worms" on the hids yesterday? any distinguishing characters that help ID them as polychaetes?

04/20/2014,15:05:02,okeanosexplorer,Amanda- we have clips of it.  It usually takes 24 hours for the video guys to get clips on to the FTP.  The time we saw those was 6:33 pm UTC.  You can download them as soon as they are posted

04/20/2014,15:05:10,robertcarney,Good Morning I can't participate much today But wanted to say that OER actually supported deployment of >100 high biomass experiments mostly in the deep Gulf.  They were colonized by tube worms and a "shipwreck" clam new to science.
