Further steps towards a chlorophyll, dissolved organic carbon, and suspended mineral remote sensing algorithm for all laurential Great Lakes.
The MTRI/NIERSC algorithm retrieves concentrations of chlorophyll (CHL), dissolved organic carbon (DOC), and suspended minerals (SM). The algorithm was validated (Pozdnyakov 2005), applied in a seven-year inter-annual analysis of SeaWiFS data in Lake Michigan (Shuchman 2006), and recently also applied to all available SeaWiFS/MODIS Lake Michigan data. The algorithm uses a hydro-optical (HO) model that consists of the absorption and backscattering coefficients for CHL, DOC, and SM at each satellite band. During the initial validation of the algorithm, a proxy HO-model from Lake Ontario was used due to a lack of insitu data in the other Great Lakes needed to create an HO-model for those lakes. Since 2004, GLERL and MTRI have been collecting optical data using a Satlantic multi-spectral profiler, with coincident laboratory measured CHL, DOC, and SM data. Using this data, new HO-models will be created for each Laurentian Great Lake. The new results will be compared with historical in-situ and seasonal phenomena for validation. Also, the differences between the old and new Ontario HO-models will be compared and analyzed. Inter-annual analyses will be performed for each lake after validation.
