Field Activity I690AT

Identifier I690AT
Alternate names I-6-90-AT,AMASSEDS
Purpose To study the movement of sediment particles in the water column, the accumulation of sediment particles on the seabed, and the effects that sediment particles have on geochemical processes in the water column and seabed.
Description Universidade Federal Fluminense,United States Geological Survey, Menlo Park, California,State University of New York. Chief Scientists: Mead Allison, Gilberto Dias. Geophysical data (Geoprobe, seismic) of field activity I-6-90-AT in Amazon Shelf, Atlantic Ocean from 05/01/1990 to 05/07/1990
Location Atlantic Ocean
Summary Geophysical equipment was successfully tested and approximately 280 km of high resolution seismic profiles were obtained. The recovery of an instrumented-tripod (GEOPROBE) off the sea bottom was attempted but without success.
Info derived High resolution seismic profiles
