Chief Scientist: Unspecified. Test data (navigation,
bathymetry, magnetics) of field activity L-1-82-NC in
Northern California from 02/02/1982 to 02/03/1982,
http://walrus.wr.usgs.gov/infobank/l/l182nc/html/l-1-82-nc.meta.html.
These data and information are intended for science
researchers, students from elementary through
college, policy makers, and general public.
Equipment Used -
navigation
bathymetry
magnetics magnetometer
Notes -
This was probably a test cruise.
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

Bank's digital data, analog data, and
metadata is provided through...
