Research Topic

Arctic Soil Carbon Storage

Research Interest

Soils of the Northern circumpolar permafrost zone store about 1.700 Gt of carbon, more than twice as much as the current atmosphere and about half of all terrestrial ecosystems. The Richter group’s scientific curiosity is therefore centered on understanding transformation, decomposition and release of organic carbon from tundra ecosystems, with the ultimate goal to understand the controls of carbon sequestration in permafrost soils and the vulnerability of soil organic matter in a future climate.
