Acoustic Backscatter from Salinity Microstructure

The contribution of salinity changes to sound speed fluctuations is often neglected in estimating the scattering cross section at high frequencies (greater than 10 kHz). To examine when salinity might be important, an expression is formulated for the scattering cross section sigma that includes sali...

description The contribution of salinity changes to sound speed fluctuations is often neglected in estimating the scattering cross section at high frequencies (greater than 10 kHz). To examine when salinity might be important, an expression is formulated for the scattering cross section sigma that includes salinity and an estimate of the cospectrum of temperature and salinity.
