Title:
Geophysical data of field activity F-8-91-CP in Central Pacific from 08/26/1991 to 09/23/1991
Abstract:
Korea Ocean Research and Development Institute (KORDI). Chief Scientists: Stephanie Ross, Ledabeth Pickthorn, Jeung-Kook Kang. Geophysical data (gravity, magnetics, 10khz, 3dot5khz, freefallgrab) of field activity F-8-91-CP in Central Pacific from 08/26/1991 to 09/23/1991, <http://walrus.wr.usgs.gov/infobank/f/f891cp/html/f-8-91-cp.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.).
