motivation is to identify the nature of the associated aerosol sources (biogenic, geochemical, or anthropogenic) as well as source regions, and to elucidate to what extend the atmospheric signal is authentically

Biological effects of marine organisms Pollutants of anthropogenic origin have also been polluting our oceans since the industrialization of the world. Coastal seas such as the North and Baltic Seas in

Small molecules may act as signaling [...] fluorescent cellular compounds. The aim of this research is to define cellular targets of natural and anthropogenic small molecules. Chemical analysis of secondary metabolites Secondary metabolites are those chemical

Resilience and vulnerability of the central Arctic Ocean food web to cumulative stress by warming and anthropogenic pollution. Head of Group: Dr. Doreen Kohlbach Figure 1 (Graphic: Doreen Kohlbach) Global warming [...] retreat, increasing influx of Atlantic waters, riverine input and marine traffic will bring more anthropogenic pollutants, even to remote Arctic regions, where they are entrained in water and sea ice, and [...] absent. In this context, Double-Trouble aims at i) assessing trophic structures and the degree of anthropogenic pollution under current environmental conditions and ii) simulating cumulative effects of warming
