ARCTIC ACOUSTIC TRANSMISSION LOSS AND AMBIENT NOISE
A model is advanced to predict arctic underwater acoustic attenuation that allows some spherical and some cylindrical divergence, coupled with a reflection loss per unit distance. Data collected from a variety of sources of measurements of arctic transmission losses are used to derive reflection los...
