About me

My research focus is to identify the processes that affect water quality in the Baltic Sea. I have investigated the role of seabeds in water quality; when do they bind nutrients effectively and when does the sediment lose that ability? These are important processes that affect how eutrophication will develop in the future. Current research questions include the form of organically bound phosphorus in the sediments, can we identify the phosphorus that will leach back into the water column and distinguish it from the stable organic phosphorus forms that will be permanently sequestered in the bottoms?

These mechanisms are important both in shallow bays and in the sea floor. In eutrophic shallow bays, the organically bound phosphorus in the sediments is responsible for the severe water quality deterioration that often occurs in spring and early summer. In the Thriving Bays project, we are investigating where this phosphorus comes from and whether it is possible to remedy the release of phosphorus from the sediments?"

Research projects

Ongoing

Completed

Horse husbandry effects on eutrophication

In this project the goal is to develop new knowledge about how horse-dense and trampled horse paddocks affect the aquatic environment, and to contribute with a scientific basis for measures on horse farms to reduce the nutrient losses from horse husbandries.

Living Coast Project

Levande kust is a full-scale demonstration project with the objective to show that it is possible to restore a eutrophic bay and to find out the costs and lessons that can be learned from such a project.

Thriving bays in the Baltic Sea

This project will investigate possibilities and remediation methods to reverse the negative environmental development taking place in many shallow bays of the Baltic Sea. It aims to contribute to new knowledge that clarify and quantify various influencing factors and effective methods to address them.
