Title:
High resolution geophysics data of field activity M-4-97-MB in Monterey Bay Sanctuary from 09/09/1997 to 09/17/1997
Abstract:
Chief Scientists: Brian Edwards, Roberto Anima. High resolution geophysics data (Huntec, 3dot5khz, GPS, YoNav, mudseis, bathymetry, integratednavigation, boomer) of field activity M-4-97-MB in Monterey Bay Sanctuary from 09/09/1997 to 09/17/1997, <http://walrus.wr.usgs.gov/infobank/m/m497mb/html/m-4-97-mb.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.).
