Abstract
This method comprises laying onto the water bottom at least one line of acoustic transducers which are put in energized condition when an iceberg is approaching the location of this line. Acoustic signals are then sequentially transmitted from at least one of said transducers, some of them being reflected by the underwater part of the iceberg and sensed by acoustic receivers located on both sides of the transmitter on the transducer line. The outline of the underwater portion of the iceberg and its draught are determined by automatically drawing the geometrical envelopes of a system of ellipsoids whose foci are the transmitter and the different receivers.
