Using recordings from MBARI's deep-sea hydrophone, marine-mammal researchers have found that the sounds of seal bombs could have significant impacts on the behavior of harbor porpoises in and around Monterey Bay. Seal bombs are explosive charges (roughly equivalent to an M-80 or cherry bomb) that commercial fishers throw into the ocean to discourage sea lions from interfering with their operations.
