- Title:
-
Geophysical data of field activity I-6-77-NP in Off west
coast Mexico from 06/19/1977 to 06/27/1977
- Abstract:
-
Geophysical data (bathymetry, magnetics, navigation) of
field activity I-6-77-NP in Off west coast Mexico from
06/19/1977 to 06/27/1977,
<http://walrus.wr.usgs.gov/infobank/i/i677np/html/i-6-77-np.meta.html>.
- Supplemental_Information:
-
Equipment Used -
bathymetry data directory exists
magnetics data directory exists
navigation data directory exists
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...
