Claim:
1. A marine sensing system comprising: a buoyant electronic unit including a syntactic foam spherical housing and further including, housed in said syntactic foam spherical housing, an underwater electric potential sensor, a pressure sensor, a magnetometer, and an accelerometer; an anchor; a deployment line connecting said anchor and a vessel; a tether connecting said anchor and said buoyant electronic unit; a zero-load-activated release mechanism, associated with said deployment line, for disconnecting said deployment line from said anchor when said anchor sinks to and reaches a bottom surface of a body of water; an acoustic-signal-activated release mechanism, associated with said tether, for disconnecting said tether from said anchor situated on said bottom surface of said body of water; wherein said buoyant electronic unit further includes a pressure-vessel container, housed in said syntactic foam spherical housing and containing said pressure sensor, said magnetometer, and said accelerometer.
