-
Geophysical data of field activity B-1-71-WF in Juan de Fuca
from 01/09/1971 to 12/01/1971
- Abstract:
-
United States Geological Survey, Menlo Park, California.
Chief Scientist: Parke Snavely. Geophysical data (magnetics,
seismic) of field activity B-1-71-WF in Juan de Fuca from
01/09/1971 to 12/01/1971,
<http://walrus.wr.usgs.gov/infobank/b/b171wf/html/b-1-71-wf.meta.html>.
- Supplemental_Information:
-
Equipment Used -
magnetics
seismic 4 sec. sweep
Notes -
Cruises are designated BA71A through BA71J, the start and end dates cover all cruises.
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...
