Title:
Mutichannel Seismic Reflection (OCS permit number 77-03) data of field activity E-3-77-AR in Beaufort Sea, Alaska from 08/02/1977 to 09/11/1977
Abstract:
United States Geological Survey,National Oceanic and Atmospheric Administration,Bureau of Ocean Energy Management. Mutichannel Seismic Reflection (OCS permit number 77-03) data of field activity E-3-77-AR in Beaufort Sea, Alaska from 08/02/1977 to 09/11/1977, <http://walrus.wr.usgs.gov/infobank/e/e377ar/html/e-3-77-ar.meta.html>.
Supplemental_Information:


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.).
