-
Lamont-Doherty Earth Observatory. Chief Scientists: Simon
Klemperer, Alan Levander, Trehu. Geophysical data (3dot5khz,
gravity, magnetics, airgun, multibeam) of field activity
EW9407 (E-7-94-NC) in Mendocino triple junction area,
northern California from 06/11/1994 to 06/25/1994,
<http://walrus.wr.usgs.gov/infobank/e/e794nc/html/e-7-94-nc.meta.html>.
- Supplemental_Information:
-
Equipment Used -
3dot5khz 3.5 khz bathymetry
gravity

airgun 240 channel seismic
multibeam hydrosweep
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>
