Equipment Used
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.
Information to be Derived
High resolution seismic profiles
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
