DOI: 10.1134/s106377101806012x
Abstract: Model experiments are used to obtain the transfer functions of an Arctic-type shallow-water acoustic waveguide in the spring–summer period, including in the presence of surface waves. The calculations were performed for frequencies from 150 to… read more here.
