In support of efforts to establish an extended continental shelf under the auspices of the Law of the Sea Treaty, the United States and other nations have been collecting high-resolution multibeam sonar data in many previously unmapped regions of the Arctic., The U.S. has conducted eight dedicated mapping cruises since 2003 (four in collaboration with Canada) in the mostly ice-covered waters north of Alaska as far north as 83.5o N (Mayer et al., 2010) using the USCG Icebreaker HEALY equipped with a 12-kHz multibeam sonar.
