- Abstract:
-
Chief Scientist: Dave Scholl. Geophysical data (airgun,
3dot5khz) of field activity L-5-75-NP in Northeast Pacific
from Dutch Harbor to San Francisco from 09/22/1975 to
09/28/1975,
<http://walrus.wr.usgs.gov/infobank/l/l575np/html/l-5-75-np.meta.html>.
- Supplemental_Information:
-
Equipment Used -
airgun single-channel airgun
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>
