Research areas
Instability of the Antarctic ice sheet and atmosphere-ice-ocean interactions of the recent history of the earth

We reconstruct the natural climate variability in the polar and subpolar regions and its impact on environmental change, atmospheric-oceanic circulation and the matter cycle for the time period of the last 5 million years. Thereby, we focus our research on duration, speed, frequency and regional patterns of long- and short-term climate variability, as well as on forcing- and feedback-mechanisms in order to improve our understanding of climate processes.

Working Area

Arctic Ocean, North Pacific, Bering Sea, Southern Ocean, Sea of Okhotsk


Sampling of marine climate archives; geochemical, sedimentological and micropaleontological investigations to characterize the environmental conditions of life
