Pressure pulses from steel cylindrical tanks imploding under hydrostatic pressure in the ocean are described. Several tanks were recovered after collapse for inspection so that the mode of collapse and resulting damage to the tanks could be correlated with the acoustic measurements. The imploding steel tanks generated acoustic signatures that differed significantly from those produced by underwater explosions and from those produced by underwater implosions of glass bottles. The observed negative onset of the implosion signatures from the steel tanks was apparently caused by the formation of an inward buckle.
