Abstract
Method and apparatus for making depth related measurements from an untethered, gravity driven oceanographic platform. The platform is a smooth streamlined, torpedo shaped body releasably carrying ballast in its nose and covered with syntactic foam for buoyancy. At the appropriate depth, the ballast is released and the body ascends under control of an interferometric homing system which guides it to a recovery vessel. The ballast may be an iron slug held in place electromagnetically.
