Chief Scientist: Gary Greene. Geological and Geophysical
data (3dot5khz, 12khz, uniboom, airgun, chaindredge, gravity,
magnetics, integratednavigation, RhoRho, miniranger) of field
activity L-2-79-NC in Northern California from 10/30/1979 to
11/05/1979,
http://walrus.wr.usgs.gov/infobank/l/l279nc/html/l-2-79-nc.meta.html.
These data and information are intended for science
researchers, students from elementary through
college, policy makers, and general public.
Equipment Used -

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...
