Summary Information for Field Activity 1990-010-FA

Area of Operations: Amazon Shelf, Brazil, South America, South Atlantic

Dates: June 16, 1990 to June 24, 1990

Chief scientist: Bill Strahle

   Richard Sternberg, Univ. WA

Objectives: To study the movement of sediment particles in the water column, the accumulation of sediment particles on the sea bed, and the effects that sediment particles have on geochemical processes in the water column and sea bed. On this leg of cruise, recover moorings deployed during Leg 2, February 1990.

Type of Activity: Mooring work;

Information to be derived:

Summary: 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 were 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.
