Abstract : The purpose was to investigate the feasibility of using such transducers as acoustic signal sources in the arctic ice pack. The experiment was to measure the in-water radiation patterns of the transducers and their efficiency as underwater sound projectors. All energy radiated in the ice that did not enter the water was considered lost insofar as efficiency determination was concerned. (Author)
