We focus on changes of landscape hydrology and their impact in the Arctic. This includes monitoring of thaw lakes, snow conditions and surface moisture with satellite data.
The Arctic is warming about twice the rate than the global average. We are interested how these changes affect specifically the benthic macro- and megafauna communities.
We are studying the biogeography, biodiversity and biocomplexity of aquatic organisms and communities in cold lotic ecosystems. We investigate high arctic river ecosystems.
We are interested in the climate's impact on the polar cryosphere for different scales, whereas in-situ field observations are building the foundation of our research.
While everyone can observe the dramatic warming of the polar region, we feel it is important to quantify also the changes in the energy and water budgets in this region.
We are analyzing species composition and biodiversity, biogeographic ranges, trophic interactions, abundances and fossil assemblages of benthic and planktonic foraminifera.
Development of methods for satellite observations on mass balance and dynamics of ice sheets and glaciers, including synergy with in situ measurements and studies of ice/climate interactions.
Investigations focus on the microbial characterization of lake ice, glaciers, ice sheets and caps as well as the snow cover and – as a novel aspect – also cloud systems.
The overall interest of this research group is the socio-economic wellbeing of arctic inhabitants and multi-perspective topics related to the development of the extractive industries in the Arctic and Sub-Arctic.
We investigate the distribution and activity of distinct clades of ammonia oxidizing archaea that we found to be associated with different nitrification rates in arctic soils.
For a correct interpretation of ice core data we need to fully understand the precipitation mechanisms that lead to the formation of the ice. Our focus is on process studies in Antarctica.
We are studying the reaction of glaciers and ice-caps in NE-Greenland through both comprehensive measurements and modelling attempts of the surface energy- and mass balance.
