Kort presentation

Jag forskar om kolkretsloppet i inlandsvatten, alltså processer som avgör om sjöar och vattendrag är kolsänkor eller kolkällor. Särskilt fokus ligger på inlagring av organiskt kol i sediment, och växthusgasavgång till atmosfären.

Inland waters, i.e. lakes, running waters and reservoirs, cover only a small fraction of the Earth’s surface, but are disproportionally active sites of carbon cycling. Inland waters receive sizeable loads of terrestrial carbon from the surrounding catchment, triggering intensive processing: the microbial degradation of organic matter leads to high carbon dioxide and methane emissions to the atmosphere, and at the same time, organic carbon burial in sediments constitutes a significant long-term carbon sink.

We combine field measurements, lab experiments and modelling, and our studies range from processes-scale understanding of degradation and preservation in sediments to catchment-scale and global-scale assessments of aquatic carbon fluxes.

A common denominator of all projects is to understand the interactions between biogeochemical cycling in aquatic systems and environmental change. A past ERC project gives a good example of the work we do.

Recently started work investigates carbon fluxes in connection to ecosystem restoration and nature-based solutions (CLIMIPHY, PredPeat).

Current projects:

  • Minimizing the climate footprint of river restoration (CLIMIPHY). PI. 2024-2027, Swedish Research Council for Sustainable Development FORMAS, 1.6 M€.
  • Minimizing the climate footprint of restoring riverine wetlands. PI. 2024-2027, Lamm Foundation, 200 000 €.
  • Anthropogenic perturbation of organic carbon burial in global lake sediments. PI. 2022-2024, Swedish Research Council (VR), 380 000 €.
  • Predicting the effects of peatland rewetting on water retention and water quality (PredPeat). Co-PI. 2022-2026, Swedish Research Council for Sustainable Development FORMAS, 1.6 M€.
  • Sources and dynamics of greenhouse gases in agricultural streams – a process-based approach for improved understanding of a large atmospheric source. Co-PI. 2022-2025, Swedish Research Council (VR), 400 000 €.
  • Leakage of environmentally problematic substances from sediment at dam removal. PI. 2021-2024, Swedish Energy Agency, 400 000 €.

Current people:

  • Simone Moras, PhD student: linkning sediment methane production to methane emission
  • Anna Bottone, PhD student: fate of sediment organic matter at dam removal
  • Sahra Gibson, PhD student: water-related ecosystem services after peatland rewetting (co-advisor)
