Title:
Data of field activity V-8-76-IN in Colombo, Ceylon--> Singapore, Malaya from 06/15/1976 to 07/19/1976
Abstract:
Chief Scientist: T. Herron. Data (gravitycore, pistoncore) of field activity V-8-76-IN in Colombo, Ceylon--> Singapore, Malaya from 06/15/1976 to 07/19/1976, <http://walrus.wr.usgs.gov/infobank/v/v876in/html/v-8-76-in.meta.html>.

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.).
