Field Activity I1090AT

Identifier I1090AT
Alternate names I-10-90-AT,AMASSEDS_CRUISE_III
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 Woods Hole Oceanographic Institution,University of Washington,United States Geological Survey, Menlo Park, California. Chief Scientist: Richard Sternberg. Geological data (Geoprobe, nets) of field activity I-10-90-AT in Amazon Shelf, Atlantic Ocean from 06/16/1990 to 06/24/1990
Location Atlantic Ocean
Summary The instrumented moorings and instrumented tripod, GEOPROBE, were recovered during this leg. These instruments had all been deployed during AmasSeds Cruise 2 in February 1990. The mooring at site M-1 was recovered first with all instruments except for one Datawell Waverider which apparently broke free and drifted out of the study. All instruments were recovered from site M-3 with no complications. At site M-2 the instrumented mooring had to be dragged for with grappling hooks because all surface buoys deployed at M-2 had broken free. All instruments on the mooring wee recovered by dragging except for one which was subsequently found and returned by Brazilian fishermen. The instrumented-tripod, GEOPROBE, was recovered using a trawling net. The instruments on the tripod were recovered undamaged and with data preserved.
