Abstract:
United States Geological Survey, Menlo Park, California. Chief Scientist: Byron Ruppel. Geophysical data (bathymetry) of field activity B-2-74-CS in Chukchi Sea, Alaska from 08/18/1974 to 09/17/1974, <http://walrus.wr.usgs.gov/infobank/b/b274cs/html/b-2-74-cs.meta.html>.
Supplemental_Information:

University of Connecticut

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/>
