Fluorescence and Reflectance for the <i>in‐situ</i> Determination of Some Quality Parameters of Surface Waters

Abstract

Abstract Ship‐based experiments around Berlin and laboratory tests were carried out in order to develop spectroscopic methods for the in‐situ determination of chlorophyll a (Chla) and chemical oxygen demand (COD cr ) of surface waters. The regression analysis of spectroscopic data (reflectance ( R ); laser‐stimulated and conventional fluorescence ( I F )) and chemical‐biological data yielded correlations of a relatively good quality.
