Chief Scientist: John Dingler. Geophysical data
(bathymetry) of field activity C-1-79-NC in Northern
California from 05/01/1979 to 05/02/1979,

Equipment Used -
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>
