Title:
Bathymetric data of field activity Z-1-91-BG in Bering Glacier, Alaska from 06/23/1991 to 06/28/1991
Abstract:
Chief Scientists: Bruce Molnia, Dick Tagg, Paul Carlson. Bathymetric data (subbottomprofiler) of field activity Z-1-91-BG in Bering Glacier, Alaska from 06/23/1991 to 06/28/1991, <http://walrus.wr.usgs.gov/infobank/z/z191bg/html/z-1-91-bg.meta.html>.
Supplemental_Information:

Equipment Used -
subbottomprofiler lowrance

Bathy profiling aboard a Zodiac in Bering Glacier

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.).
