Arctic/North Pacific Ocean Environmental Studies
The project began in 1993 as a effort to design and construct an Arctic capable low frequency acoustic source at 20 Hertz with acoustic power of 195-200 dB. The objective of the effort was to test the feasibility of acoustic monitoring of the Arctic Ocean and ice cap using long range low frequency a...
