Title:
Geophysical data of field activity P-71-69-WG in Western Gulf of Alaska from 05/05/1969 to 09/24/1969
Abstract:
Geophysical data (magnetics, bathymetry) of field activity P-71-69-WG in Western Gulf of Alaska from 05/05/1969 to 09/24/1969, <http://walrus.wr.usgs.gov/infobank/p/p7169wg/html/p-71-69-wg.meta.html>.
Supplemental_Information:

Equipment Used -
magnetics
bathymetry

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.).
