Title:
Surface sediment sampling data of field activity B-2-10-SF in San Francisco Bay, CA from 05/19/2010 to 06/19/2010
Abstract:
United States Geological Survey, Pacific Science Center. Chief Scientist: Patrick Barnard. Surface sediment sampling data (hand trowel) of field activity B-2-10-SF in San Francisco Bay, CA from 05/19/2010 to 06/19/2010, <http://walrus.wr.usgs.gov/infobank/b/b210sf/html/b-2-10-sf.meta.html>.
Supplemental_Information:

Equipment Used -
hand trowel
Notes -
San Francisco Bay Provenance Study.
Other surveys conducted as part of this provenance study
include surface samples collected from the Snavely during S-7-10-SF and
S-8-10-SF and stream samples collected by Don Woodrow S-7-10-SF.

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.).
