Research

The aim of my research is to increase our understanding of dynamics in subarctic permafrost peatlands over time and space, in relation to climate change. Perennially frozen peatlands are important reservoirs of soil organic carbon. If the climate becomes warmer and the permafrost thaws, the stored carbon can be remobilized through decomposition and emitted to the atmosphere, further increasing the concentration of greenhouse gases. My study areas are located in west-central Canada, northern Sweden and east-European Russia. Through plant macrofossil and geochemical analyses I study peatland development and permafrost history throughout the Holocene. I also use historical aerial photographs and high resolution satellite images to explore landscape dynamics and thermokarst lake distribution within the peatlands during recent decades. In a peat plateau complex in Tavvavuoma (northern Sweden) meteorological parameters and ground temperatures are monitored to increase our knowledge about how a future warmer climate may affect the permafrost, landscape dynamics and carbon balance in these ecosystems.
