"EX-13-04 Leg 1 operations commenced on July 8, 2013 in North Kingstown, RI and concluded on July 25, 2013 in New York, NY. Combined 24-hour multibeam mapping, remotely operated vehicle (ROV) and CTD/rosette operations were conducted, and included telepresence enabled shore-side participation.The 2013 Northeast U.S. Canyons Expedition, comprised of two legs, focused primarily on Northeast Canyons and inter-canyon areas.. The May 2011 NOAA Workshop on Systematic Telepresence-Enabled Exploration in the Atlantic Basin (Summary Report available at http://explore.noaa.gov/sites/OER/Documents/atl-basin-workshop-summary-oct2011.pdflast accessed 1/13/14) identified canyons and seamounts as priority areas for systematic ocean exploration. Operating areas were further refined based on input from other NOAA programs and the ocean management community. The mapping activities occurred in vicinity of Alvin, Atlantis and Hydrographer canyons, landslide features near Veatch canyon identified by USGS prior to the cruise, susepected sites of New England seep sites based on previous mapping data. EX-13-04 Legs 1 and 2 efforts built on the 2012 Atlantic Canyons Undersea Mapping Expeditions (ACUMEN). The ACUMEN expeditions have so far included seven cruises conducted by NOAA Ships Okeanos Explorer, Ferdinand Hassler and Henry B. Bigelow in 2012 and 2013. These cruises gathered baseline information on deep water canyons off the northeastern U.S. seaboard, mapping along the continental shelf and slope from Virginia to the northeastern boundary of the U.S. Exclusive Economic Zone (EEZ). These mapping operations provided the basis for preliminary ROV dive target selection during EX-13-04 Legs 1 and 2"--Cruise objectives.
