ABSTRACT:
A device for measuring sea currents at great depths as a function of the depth.
A spherical shaped plunger having negative floatability is dropped from a boat and descends to the bottom of the sea, releases its ballast and rises to the surface where it is recovered.
Acoustic responding buoys positioned geographically receive pulses emitted by the plunger and respond. The plunger-buoy distances are determined sequentially and stored in the plunger. After recovery of the plunger by the boat a computer determines the currents at the different depths.
