Title:
Geophysical data of field activity P-5-85-AT in Atlantic Ocean from 04/20/1985 to 04/26/1985
Abstract:
Chief Scientist: Byron Ruppel. Geophysical data (gravity, bathymetry, meter32, meter41) of field activity P-5-85-AT in Atlantic Ocean from 04/20/1985 to 04/26/1985, <http://walrus.wr.usgs.gov/infobank/p/p585at/html/p-5-85-at.meta.html>.
Supplemental_Information:

Equipment Used -
gravity
bathymetry
meter32
meter41

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.).
