Notes -
Contract work performed by the USGS for the U.S. Army Engineer
District Los Angeles, CA.
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:
