| An alternative methodology consisting in the application of acoustic techniques to asses detection and monitoring of toxic algal blooms is presented here. Successive steps in this direction led to already reported results [Blanc et al., 2000] achieved under the frame of a multidisciplinary research programme conducted in the Argentinean Naval Service of Research and Development. First efforts were focused in the examination of the acoustical scattering behaviour of single-species cultures of Skeletonema costatum. For this purpose a pulse-echo electronic equipment was developed, including home-made piezoelectric transducers with an operating frequency centred at 2.6 MHz. A slight modified Johnson's fluid-sphere model was used. Numerical Abundance estimates... |
