ABSTRACT:
This invention provides a stabilizer for a geophone which reduces the amount of movement of the geophone after deployment in a marine environment subjected to water currents or turbulence. The stabilizer consists of a bulb-shaped body with fin-shaped lobes. An axial cavity for receiving the geophone housing containing the geophone is located at one end of the stabilizer. The other end terminates in a tail designed to promote laminar flow and reduce turbulence coming off the geophone housing and stabilizer. When the geophone is deployed, the stabilizer and attached geophone housing come to rest on a stable, 3-prong base comprised of two adjacent lobes of the stabilizer and the end of the geophone housing opposite the end inserted into the stabilizer.
