Abstract:

A relaxation process, based on organic particulate matter plankton in open water, is described and theoretically derived. It is similar to a theoretically derived and experimentally verified process in aerosols and relates relaxation time to shear Stokes force. The derived formulas are applied to demonstrate probable significant differences among low-frequency sound-attenuation values in various water masses. Author
