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 order to widen our understanding of lake ecosystem response to climate change, we conduct palaeoenvironmental studies using sediments from lake 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 system?
- Human impact: Assessment of lake system variations in response to historical anthropogenic activity.
- Data management: Proxy quality and data compilation.
- Paleoclimate synthesis: Assessment of global teleconnections of the spatiotemporal climate variability at centennial to millennial time-scales in the Late Quaternary.
Our multi-proxy approach includes the analyses of diatoms (including ancient DNA), chironomids, elemental and physical sediment properties.
