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>
