Title:
Data of field activity T-1-70-BS in Bering Sea from 01/17/1970 to 01/21/1970
Abstract:
Data (magnetics, navigation) of field activity T-1-70-BS in Bering Sea from 01/17/1970 to 01/21/1970, <http://walrus.wr.usgs.gov/infobank/t/t170bs/html/t-1-70-bs.meta.html>.
Supplemental_Information:

Equipment Used -
magnetics data directory exists
navigation data directory exists

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.).
