Dataset Progress Status Complete
Data Update Frequency: Not planned
Purpose: The 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 continental margin (slope and rise) in the U.S. Arctic Ocean in order to obtain Raw Knudsen SEG-Y Datagram. These data are required to support any potential claim for extended jurisdiction by the United States under United Nations Convention on the Law of the Sea (UNCLOS) Article 76. The requirement is for the collection and processing of full-coverage multibeam sonar data and ancillary data in water depths of approximately 2000 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 the U.S. Geological Survey (USGS)-funded research program, USGS researchers oversaw data acquisition. University of New Hampshire researchers processed and archived the data collected from the cruise.
