During 4 surveys (between February and July 1980) the excitation and emission spectra of the dissolved organic matter in the Ems-Dollard estuary were recorded. During one survey (July 1980) the same spectra were recorded in the Wierbalg-Malzwin. The emission maximum and the shape of the fluorescent spectrum were similar in all samples. Given this founding it was possible to use the fluorescence as a measure for the concentration of fluorescent organic carbon in dissolved organic carbon. From the linear relation between fluorescence and dissolved organic carbon it is concluded that during nearly all the surveys there was relatively more fluorescent matter in the fresh water sources than in the sea water entering the estuary. It appeared that the fluorescent matter is the major constituent of dissolved organic carbon in the Ems-Dollard estuary.
