- Abstract:
-
Geophysical data (bathymetry, magnetics) of field activity
W-9-75-SP in Southern Pacific from 04/05/1975 to 04/10/1975,
<http://walrus.wr.usgs.gov/infobank/w/w975sp/html/w-9-75-sp.meta.html>.
- Supplemental_Information:
-
Equipment Used -
bathymetry
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...
