Abstract:
United States Geological Survey, Woods Hole, Massachusetts. Chief Scientist: Marty Kane. Geophysical data (magnetics, bathymetry) of field activity 71006 (U-6-71-AT) in Liberia to Puerto Rico, Atlantic Ocean from 11/24/1971 to 12/09/1971, <http://walrus.wr.usgs.gov/infobank/u/u671at/html/u-6-71-at.meta.html>.
Purpose:
These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.
Supplemental_Information:

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.).
