Publications

Stockholm University Baltic Sea Centre works to make marine research visible, synthetise research results, and forward useful knowledge to decision makers, management authorities as well as the society in general.

Results from our research projects are published in scientific journals continuously. We also produce various reports, articles and digital information targeting different audiences. In addition, we organize meetings and conferences to illuminate important marine issues, where for example scientists with common interests can meet and collaborate.

Policy briefs and consultation replies

Policy briefs are summaries of scientific knowledge, usually connected to a current managemental development or political proceeding, that aim to enhance engagement in important Baltic Sea issues. Our policy briefs are distributed to their relevant audience and presented by our experts at events.

The Baltic Sea Centre is also a frequent contributor of scientific advise to marine environmental investigations and inquiries by Swedish authorities, the European Commission and other actors.

Reports

The majority of the reports in our report series are written in Swedish, but occasionally we publish reports in English.

A robust estimation of trends in river loads of Nitrogen and Phosphorus is essential to guide the implementation of measures against eutrophication in the Baltic Sea. A key step in the assessment is flownormalization, i.e. removing the year-to-year variability in load that is solely due to variations in weather and therefore river discharge and load, but that do not constitute trends.

The efficacy of the procedure used by HELCOM-PLC to estimate flow-normalized loads based on aggregated time-series of annual discharge and estimates of the actual annual river loads has been put to question when it comes to analyzing the period 2015-2022 because of a succession of years with droughts and/or unusual distributions of daily discharge within some years.

This report presents results obtained by modeling daily concentrations and loads from low-frequency samples for 89 Swedish catchments within the drainage basins of the Baltic Proper and Öresund, using the Weighted Regression on Time, Discharge and Seasons, in order to avoid the problems caused by performing the annual aggregation ahead of the flow-normalization, and thus robustly assess the trends in flownormalized N and P loads for the decade 2010-2020.

Baltic Sea Fellows Strategic Research Area funding progress Report for the period 2017-2021

The Baltic Sea Fellows research group today consists of senior lecturers, assistant lecturers and postdoctoral fellows at six different departments. Their research range from the biogeochemical conditions and circulation processes of the Baltic Sea to long term ecosystem and food web changes and how human activities on land affect the sea. This also includes research on policy instruments and legislation that regulate management on marine protected areas, fisheries and pollution.

Blue mussel farming has been suggested as a cost effective nutrient mitigation tool in the Baltic Sea, to complement land-based measures. However, the environmental conditions of the Baltic proper, particularly the low salinity, affect the nutrient uptake efficiency of the blue mussels. Farming of mussels with the primary aim to capture nutrients from the sea has also been questioned due to the risk for unwanted environmental effects.

In this report, we discuss potential problems regarding blue mussel farming as a nutrient mitigation measure in the Baltic proper, based on (1) the effects of low salinity on mussel growth and physiology and (2) potential negative environmental effects.

Baltic Sea Centre researcher Emma Undeman has written a series of reports on hazardous substances to support the update of the HELCOM Baltic Sea Action Plan (BSAP):

Diclofenac in the Baltic Sea

Dioxins and PCBs in the Baltic Sea

Polybrominated diphenyl ethers (PBDEs) in the Baltic Sea

PFOS and other PFAS in the Baltic Sea

Publications in cooperation with others

Several series of publications at the Baltic Sea Centre are produced in collaboration with others.
