Abstract

Open-system lakes developing marshes are sensitive environments to climate changes. Mineralogical climate markers such as gypsum and dolomitized carbonate are spatialy traced using hyperspectral imagery. Climate-dependent saline soils, carbonate, organic matter and iron oxide crusts have been mapped along different stages of flooding and emersion in the past 2000 years using DAIS and ROSIS spectrometer data. Spectral behaviour interacting and masking from various mineralogical components are described on laboratory spectra. Influence of landuse on the spatial spectral behaviour of paleoenvironments is discussed. A general outline of the past pools is drawn on the area surrounding the actual marsh, providing priceless data to use in further paleoclimate limnological research and in the development of new techniques for that research.
