The 2011 mission in the high Arctic is the fourth joint ECS mapping effort by the United States and Canada.  The six-week cruise in August and September will employ the United States Coast Guard Cutter Healy to collect bathymetric data and the Canadian Coast Guard Ship Louis S. St-Laurent to collect seismic data.  Healy will sail August 15 – September 28, 2011; Louis S. St-Laurent will sail August 18 – September 29, 2011.  The objective of the mission is to collect the bathymetric and seismic data necessary to delineate an ECS in this area of the Arctic Ocean.  The Canadian ship will host an autonomous underwater vehicle, the first such deployment for under-ice multibeam bathymetric data collection from an ice breaker in the Arctic Ocean.  In addition, scientists on the two vessels will study ocean acidification, meteorology, ice behavior, ice reconnaissance, birds, and mammals.  The chief scientists for this mission are Dr. Larry Mayer, CCOM-JHC, UNH; Capt. Andy Armstrong, JHC/NOAA; and Dr. David Mosher, Geological Survey of Canada.
