Abstract
An experimental method to analyse the feasibility of acoustically determining numerical abundance (N) of phytoplanktonic organisms is presented. When unialgae cultures of diatoms and dinoflagellates are insonified, they intercept and reirradiate a fraction of the incident energy producing Acoustic Volume Scattering. An attempt to use this phenomenon as an alternative method for getting N determination of phytoplanktonic sound scatterers, is being carried out. The final objective of the proposed technique is to correlate the algae acoustic scattering parameters to sea waters pollution levels. Its theoretical
