Title:
Sediment core sampling data of field activity L-14-12-CA in Eagle Lake, Lassen County, California from 07/23/2012 to 10/08/2012
Abstract:
California State University Chico. Chief Scientist: Ben Calo. Sediment core sampling data of field activity L-14-12-CA in Eagle Lake, Lassen County, California from 07/23/2012 to 10/08/2012, <http://walrus.wr.usgs.gov/infobank/l/l1412ca/html/l-14-12-ca.meta.html>.
Supplemental_Information:

Notes -
Not all cores will be processed, sediment sampler (<http://www.ams-samplers.com/itemgroup.cfm?CNum=76>)

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.).
