This PhD project investigates how permafrost thaw in shale-rich Arctic regions affects surface water quality, with a focus on Svalbard as a natural laboratory. As the active layer deepens due to climate warming, previously frozen pyrite-rich shales are exposed to oxidation. This process releases sulphuric acid, nutrients (e.g., ammonium and nitrate), trace metals (especially manganese and iron), mercury, and other solutes into surface waters.

The project aims to:

Understand the mechanisms driving pyrite oxidation during thaw using laboratory microcosm experiments on rock and permafrost cores.
Monitor the effects of pyrite oxidation on drinking water quality (e.g., Mn contamination in Longyearbyen) and nutrient export to coastal ecosystems.
Develop a predictive understanding of water quality changes under ongoing permafrost degradation.


The four-year contract includes a year of required duties. Alternatively, the candidate may choose a three-year position which excludes these duties. Required duties for the successful candidate will be specified upon employment. Other duties may be assigned by the head of department as required.
