I have a profound interest in landscape evolution and soil processes of the Earth’s cold regions. Previously, I worked on greenhouse gas production from degrading permafrost in Siberia. Most of this research took place in summer.
In the current winter ecology project in Abisko and Vassijaure, however, I will focus on the role of winter processes in plant and microbial carbon transformations. I am measuring year-round CO2 fluxes, both photosynthetic uptake, and respiratory losses. The respiration flux is also partitioned into plant-related respiration, and microbially-driven soil respiration using a 13C labeling approach. Overall, this project will give us a better insight into cold-season CO2 emissions from high-latitude ecosystems and a better constraint of an often-neglected climate-feedback.
