EX1204: Northeastern Canyons and Continental Margins Exploration on NOAA Ship Okeanos Explorer between 20120529 and 20120613
During the Okeanos Explorer (EX) mission EX1204, the vessel
will sail from Norfolk, VA, along the continental shelf break of the U.S. East
Coast from Virginia to Rhode Island, to the ship’s home port of Davisville, RI.
The goal of the mission is to explore northeastern canyons and continental
margins using the ship’s Kongsberg EM302 multibeam sonar, Simrad EK60, and
Knudsen sub-bottom profiler. CTD casts are probable around different locations
around the axis of the canyons with niskin bottle firings for water sampling,
depending upon staff availability. XBT casts will be fired every 4 hours for
system calibration checks. Multibeam data collected in a sloped but featureless
area in the vicinity of McMaster canyon will be used in comparison with data in
this same area recorded by the NOAA Ship Hassler and the NOAA Ship Bigelow.
