Britta Sannel is an Associate Professor at the Department of Physical Geography, Stockholm University, specializing in Arctic environments and permafrost peatland dynamics. Her research examines climate change impacts on permafrost stability, carbon cycling, and thermokarst lake evolution across Fennoscandia, Canada, and Russia. She coordinates the Master's Programme in Polar Landscapes and Quaternary Climate and has led over 30 international field courses.
- Key Research Areas:
- Permafrost thaw mechanisms and carbon feedbacks
- Peatland vegetation succession under warming
- Historical climate reconstructions via isotope analysis
- Thermokarst lake dynamics (1950s-present)
- Projects:
- Mercury Remobilization from Degrading Permafrost
- Climate Warming Effects on Peat Plateau Complexes
- Methodologies:
- Plant macrofossil and geochemical analyses
- Accelerator mass spectrometry radiocarbon dating
- Field monitoring (ground temperatures, meteorological parameters)
- Remote sensing of thermokarst changes
Her work reveals that subarctic peatlands may sustain carbon sink capacity through Sphagnum dominance shifts, while permafrost thaw creates methylmercury hotspots and alters soil thermal regimes. Recent publications emphasize vegetation-temperature decoupling and groundwater heat transport in permafrost environments.
