Marine seismic bottom geophone coupling and anchor

DETAILED DESCRIPTION In accordance with the present invention, there is provided a marine seismic bottom geophone coupling and anchor, comprising essentially two rectangular fabric sections attached together along their edges and along a plurality of lines between said edges to form a plurality of pockets.
Each pocket is filled with a weighting material.
A connecting flap is attached to the outer surface of one of the two fabric sections along a first of two opposing edges and a corresponding connecting strip is attached to the outer surface of the second fabric section so that the fabric sections can be rolled and held in a generally cylindrical shape.
When the device is rolled around and bound to a marine seismic bottom cable and seismic detector, it simultaneously acts as an anchor to hold the detector in the desired position on the marine bottom, provides good coupling to the marine bottom, and reduces or eliminates noise caused by detector and cable movement in response to ambient current conditions.
