Abstract:
Bndo-Cnexo. Chief Scientist: Unspecified. Data (bathymetry, gravity, magnetics, navigation) of field activity C-1-72-NA in North Atlantic, Portugal, Spain, Morocco from 08/11/1972 to 08/21/1972, <http://walrus.wr.usgs.gov/infobank/c/c172na/html/c-1-72-na.meta.html>.
Supplemental_Information:

Equipment Used -
bathymetry data directory exists
gravity data directory exists
magnetics data directory exists
navigation data directory exists
Notes -

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.).
