PurposeThe National Oceanic and Atmospheric Administration (NOAA), on behalf of the United States Government, has a requirement to carry out surveys of specific regions on the U.S. continental margins (slope and rise) in order to obtain high-resolution multibeam bathymetry. These data are required to support any potential claim for jurisdiction of an extended continental shelf by the United States under Article 76 of the United Nations Convention on the Law of the Sea (UNCLOS). The requirement is for the collection and processing of full-coverage multibeam sonar data and ancillary data in water depths of approximately 1000 to 5000 m in order to precisely define the location of the 2500-m isobath and the "foot of the slope" as defined under UNCLOS Article 76. As part of their NOAA-funded research program, University of New Hampshire (UNH) researchers oversaw data acquisition, processing and archiving of the data collected during the cruise.
