Title:
Geophysical data of field activity 86025 (S-7-86-CB) in Caribbean Sea from 10/24/1986 to 11/01/1986
Abstract:
United States Geological Survey, Woods Hole, Massachusetts. Chief Scientists: Barry Irwin, John Gann. Geophysical data (integratednavigation, GPS, transitsatellite, gravity) of field activity 86025 (S-7-86-CB) in Caribbean Sea from 10/24/1986 to 11/01/1986, <http://walrus.wr.usgs.gov/infobank/s/s786cb/html/s-7-86-cb.meta.html>.
Supplemental_Information:

Equipment Used -

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.).
