ABSTRACT:
An underwater acoustic release system includes a buoyed member with an attached line that is released from a preselected underwater location using an acoustic signal that activates a heating element to melt a volume of wax or like meltable substance. The wax expands, pushing a cylinder or like linkage to release the buoy and its attached line so that it rises to the surface identifying the location for a survey vessel.
