Equipment Used
|
|
|
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.
|
|
|
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.
