Abstract

Dynamic of the vegetation of harmful algal Heterocapsa triquetra in the Southern Baltic water was studied. The composition, abundance, and biomass of phytoplankton community were under investigation. On the base of the direct determinations of the abundance H. triquetra and satellite normalized brightness of surface water of Baltic Sea in different spectral ranges the attempt to development the algorithm for detecting H. triquetra in H. triquetra - dominated natural communities have been made. Comparison with pigment concentrations and cell counts suggests that the algorithm can flag the presence of H. triquetra and provide quantitative information about chlorophyll concentrations in cells. It is shown that the algorithm can be useful for operative analysis of condition vegetation of H. triquetra.
