Description:
Abstract:
Hawaii Institute of Geophysics. Chief Scientist: Jim Eade. Geophysical data (radar, sextant, 7khz) of field activity A-1T-77-CP in Tonga, Central Pacific from 09/16/1977 to 10/02/1977, <http://walrus.wr.usgs.gov/infobank/a/a1t77cp/html/a-1t-77-cp.meta.html>.
Purpose:
These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.
Supplemental_Information:

Equipment Used -
radar
sextant
7khz bathymetry
Notes -
Hawaii Institute Geophysics for CCOPSOPAC

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.).
