Climate change already thaws permafrost, reduces sea-ice and increases riverine discharge over much of the pan-Arctic, triggering important [...] impact of shifting seasonality, fresher water, changing nutrient supply and greater proportions of permafrost-derived carbon on coastal waters CACOON Aims CACOON addresses this knowledge gap by investigating [...] watershed area. CACOON will quantify the effect of changing freshwater export and terrestrial permafrost thaw on the type and fate of river-borne organic matter delivered to Arctic coastal waters, and

Typical questions are: Which sea ice types can be separated in radar images? How do polynyas [...] and deformation? Which sensor combinations are optimal for classification of land cover units in permafrost regions? How can we retrieve snow accumulation rates from satellite data? The results of our analyses
