Title:
Data of field activity P-2-83-AT in Atlantic Ocean from 06/16/1983 to 06/25/1983
Abstract:
Chief Scientist: Byron Ruppel. Data (bathymetry, gravity, navigation) of field activity P-2-83-AT in Atlantic Ocean from 06/16/1983 to 06/25/1983, <http://walrus.wr.usgs.gov/infobank/p/p283at/html/p-2-83-at.meta.html>.
Supplemental_Information:

Equipment Used -
bathymetry data directory exists
gravity data directory exists
navigation data directory exists

Similar information is available for thousands of other USGS/CMG-related Activities.
If known, available are Activity-specific navigation, gravity, magnetics, bathymetry, seismic, and sampling data; track maps; and equipment information; as well as summary overviews, crew lists, and information about analog materials.
If available, access to physical samples is described in the "WR CMG Sample Distribution Policy" at: <http://walrus.wr.usgs.gov/infobank/programs/html/main/sample-dist-policy.html>
Primary access to the USGS/CMG Information Bank's digital data, analog data, and metadata is provided through... <http://walrus.wr.usgs.gov/infobank/>
This page accomodates a variety of search approaches (e.g., by platform, by region, by scientist, by equipment type, etc.).

      Indirect_Spatial_Reference: Atlantic Ocean
      This is a Point data set. It contains the following vector data types (SDTS terminology):
      • Point

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.00001. Longitudes are given to the nearest 0.00001. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1927.
      The ellipsoid used is Clarke 1866.
      The semi-major axis of the ellipsoid used is 6378206.4.
