Acoustic Method for Measuring the Density of Particles in Water

The acoustic technology has a great potential to measure the concentration of particles in water which is one of the parameters for understanding ocean ecology. To achieve this purpose, the forward acoustic propagation model has been considered as a method to obtain concentration and particle size. The Gaussian lognormal distribution was used to describe the particle matters condition in suspended water. Base on the model, a nonlinear inversion process took values of attenuation into calculation and get parameters of concentration, average radius and variance.
