Abstract:
United States Geological Survey, Menlo Park, California,Subsea Systems,Seafloor Surveys, Inc.. Chief Scientist: Brian Edwards. Geophysical data (24channel, Geopulse, GPS) of field activity E-1-01-SC in San Pedro Bay, Los Angeles, CA from 01/08/2001 to 01/13/2001, <http://walrus.wr.usgs.gov/infobank/e/e101sc/html/e-1-01-sc.meta.html>.
Supplemental_Information:

Equipment Used -

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.).
