Title:
Geological and Geophysical data of field activity D-1-79-EG in Eastern Gulf of Alaska from 05/24/1979 to 06/01/1979
Abstract:
United States Geological Survey, Menlo Park, California. Chief Scientists: Mark Wheeler, Bruce Molnia. Geological and Geophysical data (3dot5khz, Shipekgrab) of field activity D-1-79-EG in Eastern Gulf of Alaska from 05/24/1979 to 06/01/1979, <http://walrus.wr.usgs.gov/infobank/d/d179eg/html/d-1-79-eg.meta.html>.
Supplemental_Information:

Equipment Used -
3dot5khz 3.5 khz bathymetry
Shipekgrab

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.).
