Title:
Geophysical data of field activity B-1-72-NP in Northern Pacific from 01/11/1972 to 04/03/1972
Abstract:
United States Geological Survey, Menlo Park, California. Chief Scientist: Dave Clague. Geophysical data (transitsatellite, 12khz, magnetics, 3dot5khz) of field activity B-1-72-NP in Northern Pacific from 01/11/1972 to 04/03/1972, <http://walrus.wr.usgs.gov/infobank/b/b172np/html/b-1-72-np.meta.html>.
Supplemental_Information:

Equipment Used -
transitsatellite
12khz Harris 853-D 2-2/3 bathymetry
magnetics Varian Proton-Precession magnetometer
3dot5khz 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.).
