Title:
Geophysical data of field activity C-20-69-NP in Robert D. Conrad from 08/09/1969 to 09/03/1969
Abstract:
Chief Scientist: S. Lieber. Geophysical data (transitsatellite, magnetics, gravity, airgun, 3dot5khz, 12khz) of field activity C-20-69-NP in Robert D. Conrad from 08/09/1969 to 09/03/1969, <http://walrus.wr.usgs.gov/infobank/c/c2069np/html/c-20-69-np.meta.html>.
Supplemental_Information:

Equipment Used -
transitsatellite navigation
magnetics l-DGO Mfg. Proton-Precession magnetics
gravity Anschultz Electrictable, Askania GSS2-6 gravity
airgun l-DGO 25 cu. in. airgun
3dot5khz 3.5k khz bathymetry
12khz 12 khz bathymetry

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.).

      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.
