Geophysical data of field activity P-1-83-GM in Gulf of
Mexico from 01/05/1983 to 01/09/1983
- Abstract:
-
Chief Scientist: Jon Childs. Geophysical data (3dot5khz) of
field activity P-1-83-GM in Gulf of Mexico from 01/05/1983 to
01/09/1983,
<http://walrus.wr.usgs.gov/infobank/p/p183gm/html/p-1-83-gm.meta.html>.
- Supplemental_Information:
-
Equipment Used -
3dot5khz 3.5 khz 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...
