Centre for Coastal Ecosystem and Climate Change Research (CoastClim)

CoastClim is an interdisciplinary consortium of researchers and advanced research infrastructure that facilitates addresing questions regarding the links between coastal biodiversity and our climate. It brings together expertise in modelling, marine ecology, biogeochemistry and atmospheric research as well as policy analysis and communication from Stockholm University and University of Helsinki.

Baltic Nest Institute

The Baltic Nest Institute (BNI) at Stockholm University provides scientific basis for ecosystem-based management of the Baltic Sea by maintaining and developing data bases and models with a holistic Baltic Sea perspective.

Ecosystem modelling

We develop models to facilitate decision-making at national and international level, particularly with regard to eutrophication and its links to climate change and higher nutrient levels.

About me

In my work I use numerical model simulations to understand and describe physical and biogeochemical processes in the Baltic Sea. My background is mainly in physical oceanography, but my research is primarly focused on transports of nutrients, carbon and alkalinity between land, water, and air and also transformations of these substances within the Baltic Sea. One overarching aim of my research is to elucidate how the Baltic Sea has changed in the past and also what changes that could be expected in the future depending on carbon dioxide emissions, climate change, and eutrophication.


My research interests:

  • The coupling between physical and biogeochemical processes in the Baltic Sea
  • Historical and future changes of carbon and nutrient cycling, deep water oxygen conditions, and ocean acidification
  • Cycling of iron, sulfur, and phosphorus in Baltic Sea sediments, impact on alkalinity and pH in the water column

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.

TRIACID: Mapping acidification trends in the Baltic Sea

The TRIACID project has mapped acidification trends in different regions of the Baltic Sea during the past 40 years. The project has described spatial variation and trends in pH status, and the main drivers of changing pH have been identified.

OMAI – Operational Marine Acidification Indicator

The Baltic Sea is highly influenced by the catchment areas, whith more complex pH dynamics than in the open ocean. This research project improves the temporal and spatial coverage of acidification monitoring, to broaden the understanding of current acidification trends and to improve the capacity to predict future changes.
