<purpose>
These data and information are intended for science
researchers, students from elementary through
college, policy makers, and general public.

Equipment Used -

3dot5khz                      3.5 khz bathymetry

12khz                         12 khz bathymetry

uniboom

airgun                        single-channel airgun

gravity

magnetics                     magnetometer

GPS                           GPS satellite

integratednavigation

RhoRho                        LoranC Rho-Rho

airgunmonitor                 single-channel airgun monitor

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.).
