REMOTE SENSING OF SEASONAL SPATIAL VARIATION OF PHYTOPLANKTON PIGMENTS IN LAKE ERIE (E) (E)

In the past decade, the western basin of Lake Erie has experienced significant cyanobacterial blooms every summer. The toxins produced by these blooms pose health threats to humans and wildlife. In this study a multiple pigment inversion model was built to retrieve the pigment absorption coefficients from remote sensing data. With this method, the absorption coefficients of chlorophylls a, b and c, carotenoid, phycoerythrin and phycocyanin can be effectively determined with mean absolute relative errors less than 30%. Here by analysis of the seasonal spatial variation of these pigments, the various stages (initiation, peak, and senescence) of the bloom were documented from imagery of the Moderate Resolution Imaging Spectroradiometer aboard the Aqua satellite (MODIS-Aqua). These results show the possibility of providing timely and continuous predictions of ecosystem change as an aid for effective management, and improving forecasts of water quality to reduce risks to human health associated with recreational exposure and human consumption of the lake water.
