Gridded (100 m/pixel) full coverage, processed Bathymetry Data - Data were first reduced for position, elevation, orientation, water-column sound-speed and refraction effects and are provided as a cleaned gridded ESRI ASCII bathymetry grid.
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 ESRI ArcGIS Grid. 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 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 their NOAA-funded research program, University of New Hampshire (UNH) researchers oversaw data acquisition, processing and archiving of the data collected during the cruise.

The cruise report for this product is located at: http://ccom.unh.edu/publications/us-law-sea-cruise-map-and-sample-us-arctic-ocean-margin. UNH was responsible for generating gridded bathymetry data sets at sea. The UNH grid was generated from the UNH-processed sounding data. Information about UNH Center for Coastal and Ocean Mapping field activity are online at http://ccom.unh.edu/unclos/reports.htm.

Horizontal positioning is accurate to better than 5 meters (at 95% confidence) during all surveying. All positioning is referenced to the WGS84 Datum.
No attempt was made to determine the accuracy of the systems although recorded depths are typically within +/-10 m of the center-beam multibeam sounding.
CC0M-UNH processed the raw data and generated gridded bathymetry and acoustic backscatter data sets at sea. Individual ping and beam data were edited for fliers and then merged with navigation. A bathymetric grid and a backscatter mosaic were generated. Data were gridded at a grid size 100 m/pixel. These data were output in x, y, depth format as ESRI ASCII grid file.
