Detection of Algae-blooms in the Baltic Sea with MERIS-data

Kurzfassung

Satellite remote sensing is an effective tool for the regular observation of the ecological state of the environment. The availability of MERIS radiances in the visible and near-infrared parts of the spectrum gives the useful opportunity of regular observation the water quality in coastal waters. Therefore the development and validation of appropriate interpretation algorithms is necessary. A special case-2 interpretation algorithm, developed for the Baltic Sea, will be presented. The Algorithm is basing on atmospheric corrected MERIS reflectances and estimates the concentrations of Phytoplankton, inorganic Sediments and Yellow Substance. The algorithm - a model based inversion/regression technique - will be introduced and demonstrated on examples in the Baltic Sea.
