    Autochart is a GMT-based custom bathymetric map generator from Vents Programs' Northeast Pacific multibeam data base, satellite-derived bathymetry or DBDB5 data. Earthquake source locations from NOAA's hydroacoustic monitoring project can also be superimposed on the maps (Autoseismic).

    Bathymetric data were collected from different seafloor survey systems. Coverage is limited. For topological data on land, especially in small-scale, use DBDB5.

    Using Navy's DBDB5 world bathymetric and topological data. The data are in Geographic Coordinates. Note that it cannot handle the longitude range that cross the Greenwich Meridian. For detail seafloor bathymetric, use the MultiBeam Database.

    The bathymetric map of the northern Bering Sea region, plate 1 of USGS Professional Paper 759-B, 1976, was generated using published National Ocean Service maps and an unpublished map from Univ. of Washington. The region covered by the map includes the eastern tip of the Chukotka Peninsula, Russia, east to the Seward Peninsula and northern Yukon Delta, Alaska, and south to St. Lawrence Island, Alaska. The portion digitized was west of the Exclusive Economic Zone (EEZ, or Convention Line of 1867). Only the Russian side of the map was included in the coverage because better data were available for the U.S. side of region from the National Ocean Service, National Geophysical Data Center.

    Using Satellite Image, provided by David T. Sandwell from Scripps Institute of Oceanography, La Jolla, CA 92093, for bathymetric and topological data. The data are from a satellite image in Mercator Map Projection. The retrieved data by this program will be in Geographic Coordinates. Note that it cannot handle the longitude range that cross the Greenwich Meridian. For detail seafloor bathymetric, use the MultiBeam Database.

    Bathymetric contours were generated from soundings collected by National Ocean Service vessels from 1900 to 1971. The 1:250,000 maps are available for U.S. coastal waters. Bathymetric contours are in meters, with 10 meter intervals out to 200 m, supplemented by 2 m contours. Beyond 200 m, contours are at 50 m intervals to maximum depth. The GIS database derived from these maps includes the Bering, Chukchi, and Beaufort Seas in western and northern Alaska. Approximately 100 maps.

    Data Type: Birds; This coverages includes damage assessment survey areas (primarily transects) for the Naked Island group and North Knight Island, Ingot Island, Eaglek Bay and Squaw Bay. Analysis of bathymetry zones was used to help describe some survey areas. Also included are restoration survey areas for western Prince William Sound (a subset of transects established for EVOS Bird Study 2).

    Data Type: Exxon Valdez Oil Spill; Raw bathymetric data was received from National Ocean Services (NOS). The data is in a fifteen second grid format with an average sea depth recorded for each cell. Areas of missing or scattered data were covered by manual entry of over 12,000 points from published NOS charts (scale 1:80,000). Contour intervals were generated from this data and the State coastline by using Delauney Bivariate interpolation methon (ARC/INFO rev. 5.0.1 TIN), and reflect mean lower low water. This dataset was compiled to provide bathymetry information for the oil spill damage assessment and restoration efforts.

    Bathymetric contours were generated from soundings collected during surveys and cruises by the Hydrographic Office, National Ocean Survey, and Coast and Geodetic Survey. The region covered by the map is the Bering Sea Shelf from Bristol Bay, Alaska to the Gulf of Anadyr, Russia. Bathymetry is in meters at 10 m intervals, with 5 m supplemental contours. The digitized portion includes the Anadyr Gulf and Bering Strait in Russian waters (west of the Exclusive Economic Zone), to supplement digitized National Ocean Service maps of US waters (Coastal Shelf Bathymetry of the Bering, Chukchi, and Beaufort Seas).

    Bathymetric contours were generated from soundings collected by National Ocean Service vessels from ~1900 to ~1971. The 1:250,000 maps are available for U.S. coastal waters. Bathymetric contours are in meters, with 10 meter intervals out to 200 m, supplemented by 2 m contours. Beyond 200 m, contours are at 50 m intervals to maximum depth. The GIS database derived from these maps includes the Bering, Chukchi, and Beaufort Seas in western and northern Alaska (~100 maps).
