I am currently looking into the role of non-growing and shoulder season carbon and nitrogen dynamics for accurate annual greenhouse gas budgets of pristine northern ecosystems. An automated static chamber system is measuring soil-atmosphere CO_2, CH₄, and N₂O exchange continuously and in high-frequency at the Siikaneva peatland and upland forest, Finland. Together with micrometeorological and biogeochemical monitoring, I am investigating the effects of soil freezing and thawing on the ecosystems’ annual greenhouse gas drivers.

Overall, the FluxWIN project aims to understand how now-frozen soils will respond to permafrost thaw as soils that are always frozen shift to becoming seasonally or perennially thawed with increased plant activity through earlier onset of spring and warmer winters.
