Title:
Geophysical data of field activity B-1-71-WF in Juan de Fuca from 01/09/1971 to 12/01/1971
Abstract:
United States Geological Survey, Menlo Park, California. Chief Scientist: Parke Snavely. Geophysical data (magnetics, seismic) of field activity B-1-71-WF in Juan de Fuca from 01/09/1971 to 12/01/1971, <http://walrus.wr.usgs.gov/infobank/b/b171wf/html/b-1-71-wf.meta.html>.
Supplemental_Information:

Equipment Used -
magnetics
seismic 4 sec. sweep
Notes -
Cruises are designated BA71A through BA71J, the start and end dates cover all cruises.

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.).
