Abstract
A marine seismic seabed cable for use on or near the seabed includes at least one pulling cable, a data cable, and a sleeve which surrounds the data cable and the pulling cable. Groups of geophones and position metering instruments are placed along the cable with the position metering instruments and geophones being disposed in a geophone sphere. The geophone sphere and the pulling cables are to a substantial degree mechanically isolated from each other so that, for example, shocks and signals against the seabed cable will only be transferred to a minor extent to the geophone sphere.
