Title:
Data of field activity K-1-71-NP in North Pacific from 05/14/1971 to 05/23/1971
Abstract:
Data (bathymetry, gravity, magnetics) of field activity K-1-71-NP in North Pacific from 05/14/1971 to 05/23/1971, <http://walrus.wr.usgs.gov/infobank/k/k171np/html/k-1-71-np.meta.html>.
Supplemental_Information:

Equipment Used -
bathymetry
gravity
magnetics

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.).
