- Abstract:
-
Chief Scientist: Byron Ruppel. Geophysical data
(bathymetry, gravity) of field activity P-4-83-AT in Atlantic
Ocean from 07/12/1983 to 07/27/1983,
<http://walrus.wr.usgs.gov/infobank/p/p483at/html/p-4-83-at.meta.html>.
- Supplemental_Information:
-
Equipment Used -
bathymetry
gravity
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...
