View new CMGDS report form

AKA: none

Other ID: I-6-90-AT,AMASSEDS

Status: Completed

Organization(s): USGS, Pacific Coastal and Marine Science Center, State University of New York, Universidade Federal Fluminense

Funding Program(s):

Principal Investigator(s): Mead Allison

Affiliate Investigator(s): Gilberto Dias

Information Specialist(s):

Data Type(s): Time Series: Mooring (physical oceanography), Seismics: Sub Bottom Profiler

Scientific Purpose/Goals: 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.

Vehicle(s):

Start Port/Location: Belem, Brazil

End Port/Location: Belem, Brazil

Start Date: 1990-05-01

End Date: 1990-05-07

Equipment Used: Geoprobe, seismic

Information to be Derived: High resolution seismic profiles

Summary of Activity and Data Gathered: 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.
