Title:
Data of field activity W-5-75-NR in North Carolina from 01/01/1975 to 02/14/1975
Abstract:
WesternGeco. Data (navigation, seismic) of field activity W-5-75-NR in North Carolina from 01/01/1975 to 02/14/1975, <http://walrus.wr.usgs.gov/infobank/w/w575nr/html/w-5-75-nr.meta.html>.
Supplemental_Information:

Equipment Used -
navigation data directory exists
seismic data directory exists

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.).
