Although scientists have discovered no direct link between the seismic surveys and the recent spate of whale and dophin deaths, no one has looked carefully at possible explanations. Rectified diffusion, a physical consequence of sound waves in the mid frequency range, could cause marine mammals to experience tissue damage akin to "the bends." If a connection between offshore wind activities and whale deaths does not exist, then why has NOAA issued over 700,000 permissions to incidentally "take" marine mammals?
