A method of measuring deep ocean currents is proposed, utilizing many one-shot explosive neutrally buoyant floats. These floats, which explode after a preset time in the water, may be located over long distances by making use of the oceanic sound channel. The useful data will consist of the mean drift for some depth range, the variance with respect to the mean drift, and a possible correlation between vertical and horizontal scatter. There are to be 20 floats deployed in a cluster around 1000 meters deep. Each float will telemeter its depth to a surface ship immediately after deployment. The floats will explode after several weeks, and the explosions will be located by hyperbolic navigation in the sound channel. This report concerns primarily the developmental aspect of the system, including the detailed design of the floats.
