Arctic Lake System Dynamics

Siberia, a key region of ongoing climate change, offers the potential to pinpoint climatic and ecological connections between Arctic and boreal areas in the Northern Hemisphere. In order to widen our understanding of lake ecosystem response to climate change, we conduct palaeoenvironmental studies using sediments from lakes located along north-south and west-east transects in Siberia.

Our research foci are

  • Lake ontogeny: reveal inherent arctic lake system and catchment dynamics.
  • Seasonality: How do changes in winter ice-cover and summer open season influence Arctic lake systems?
  • Human impact: Assessment of lake system variations in response to historical anthropogenic activity.
  • Data management: Palaeolimnological proxy quality and data analytics.
  • Palaeoclimate synthesis: Assessment of global teleconnections of spatiotemporal climate variabilities at centennial to millennial time-scales.

Our multi-proxy approach includes the analyses of diatoms (including ancient DNA), pollen, chironomids, geochemical (elements and minerals) and physical sediment properties.
