Title:
Geophysical data of field activity POWLP2-85-CB (P-2-85-CB) in Caribbean from 03/01/1985 to 03/11/1985
Abstract:
United States Geological Survey, Reston, Virginia. Chief Scientist: Byron Ruppel. Geophysical data (bathymetry, gravity, meter32, meter41) of field activity POWLP2-85-CB (P-2-85-CB) in Caribbean from 03/01/1985 to 03/11/1985, <http://walrus.wr.usgs.gov/infobank/p/p285cb/html/p-2-85-cb.meta.html>.

P285CB Cruise Report exists at Woods Hole

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... <http://walrus.wr.usgs.gov/infobank/>
This page accomodates a variety of search approaches (e.g., by platform, by region, by scientist, by equipment type, etc.).
