Title:
Solomon Islands Marine Geology and Geophysics from Field Activity: L-6-84-SP (bathymetry, gravity, magnetics, navigation, oceanography, samples, seismic)
Abstract:
This data set contains data, metadata, and formal metadata associated with a marine data collection activity referred to by the USGS/CMG Activity ID: L-6-84-SP

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.).
