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.
|
|
|
Information to be Derived
|
|
High resolution seismic profiles
|
|
|
Summary
|
|
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.
