The SNAC-cluster now aims at providing a synoptic view of the changing CAO. The “PaRaThA” project is based on the time-integrated information from the natural [...] sedimentation rate and the spatial distribution of the controlling environmental parameters in order to: to quantify the content of organic carbon (OC) in the sediments of the Baltic Sea, assess their OC a

The transparent background [...] addition, the δ 15 N values of the organic matter also provide information on the efficiency of the biological pump if terrigenous input can be excluded. The δ 13 C and δ 15 N values of organisms, on the other [...] archives. On the other hand, we determine the δ 18 O values in ice and water samples from the Arctic and Antarctic, as well as the δ 13 C values of dissolved inorganic carbon in the water of the polar oceans

Given its smaller overall land mass, there is less permafrost in the Southern Hemisphere. Although the Antarctic offers the constant low temperatures needed, the amount of land where [...] where the majority of biological and biochemical activity takes place, it is also referred to as the “active layer”, which, as the thawing layer, is not considered to be part of the permafrost. The layer
