Service Description: Seafloor bathymetry (depth in meters) with hillshade for the Gulf of Alaska.

This Data was NOT produced for Navigation, has NOT been certified by UNH/CCOM-JHC, and must NOT be used in any form or manner for Navigation.
Please see the following Center for Coastal and Ocean Mapping's (CCOM) cruise report for full information on this data:
• http://www.ccom-jhc.unh.edu/publications/Gardner_05_cruise_report_KM0514.pdf
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 order to obtain bathymetric data. 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 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 at the CCOM oversaw data acquisition, processing and archiving of the data collected during the cruise.
The bathymetric grid was generated from data which were first reduced for position, elevation, orientation, water-column sound-speed and refraction effects. The shaded-relief model (hillshade) is illuminated from an azimuth of 315 degrees with a sun elevation of 45 degrees. All depths are reported in meters.
