Lakes in the northernmost latitudes are widely considered to be a significant source of the greenhouse gas methane. In order to improve currently available climate-change projection models

Here the focus lies on geoscientific studies in periglacial areas at the edge of ice sheets and in permafrost regions, as well as on modelling and experimental investigations on atmospheric processes in the [...] and the Arctic. They increasingly devote themselves to Arctic research - in particular to the permafrost areas of Siberia and the Arctic archipelago of Svalbard – because these regions hold the keys to [...] to the understanding of the climate events in Europe.

The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing
