Title:
Geophysical data of field activity S-2-86-AT in Atlantic Ocean from 07/29/1986 to 08/04/1986
Abstract:
Chief Scientist: John Gann. Geophysical data (gravity, dopplersonar, GPS, integratednavigation, RhoRho, transitsatellite) of field activity S-2-86-AT in Atlantic Ocean from 07/29/1986 to 08/04/1986, <http://walrus.wr.usgs.gov/infobank/s/s286at/html/s-2-86-at.meta.html>.
Supplemental_Information:

Equipment Used -

transitsatellite

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.).
