Short project description

To reduce the emissions of greenhouse gasses, the Danish government has decided to take low lying, carbon rich soils out of agricultural production and convert them to rewetted peatlands. At Aarhus University we are measuring the greenhouse gasses (GHG)  from different peatlands that have different rewetting ages and strategies. We measure the greenhouse gas emissions (CO₂ and CH₄) by means of Eddy Covariance and monitor the water table depth and the vegetation dynamics (both phenology and species). In correlation with these Eddy Covariance measurements also manual and automatic chambers are deployed.

The proposed thesis could focus on a literature study on the knowledge there is about rewetting strategies, working on the comparison of the chamber and EC method, modelling the vegetation dynamics and GHG emissions. The options are variable and depend on the student’s interest and background. The student will work with PhD’s and Postdocs in the same area of research.
