Title:
Geological and Geophysical data of field activity L-3-90-NC in Central California from 04/23/1990 to 05/09/1990
Abstract:
Chief Scientists: Dennis Mann, Steve Lewis. Geological and Geophysical data (24channel, 3dot5khz, 12khz, gravity, magnetics, airgun, integratednavigation, GPS, RhoRho, airgunmonitor, sonobuoy) of field activity L-3-90-NC in Central California from 04/23/1990 to 05/09/1990, <http://walrus.wr.usgs.gov/infobank/l/l390nc/html/l-3-90-nc.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.).
