Monterey Bay Aquarium Research Institute. Chief Scientist:
David Caress, MBARI. Chirp and Multibeam Sonar data of field

Notes -
USGS contracted for 2 18-hour surveys of selected areas using the MBARI AUV, conducted on Aug. 21-22, 2010
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...

This page accomodates a variety of search
approaches (e.g., by platform, by region,
