No miracle solution for the Baltic Sea
Seabased measures is not an alternative to landbased measures in abating eutrophication in the Baltic Sea. Landbased measures will eventually lead to improvement, not only in the sea but also in lakes and rivers, and are necessary for a sustainable society, leading Baltic Sea researchers state.

Modeling organic contaminants in the Baltic Sea
Organic contaminants constitute one of many stressors that deteriorate the ecological status of the Baltic Sea. The novel modeling tool BALTSEM-POP for organic contaminants also includes other types of stressors and provides many important management applications.

Carbon isotopes in the Baltsem model
Baltic Nest researchers have now expanded the BALTSEM model to include carbon isotopes. The isotopic compositions of inorganic and organic carbon species in the Baltic Sea are mainly controlled by phytoplankton production and respiration and the related air-sea CO2 fluxes. This method could also have important applications for estimates of greenhouse gas emissions in other areas.

Bacteria in the Baltic Sea reduce acidification
Alkalinity production in the Baltic Sea is much larger than previously known. Researchers at Stockholm University determined the alkalinity delivered by rivers to the Baltic Sea and concluded that there are large internal sources in the sea that generate alkalinity.

Read more about Baltic Sea regime shifts
The interdisciplinary project Regime Shifts in the Baltic Sea Ecosystem - Modelling Complex Adaptive Ecosystems and Governance Implications has now entered its final year. The articles published in the project up to date are now available on our web, many with abstracts or short introductions for easy access.

BNI contributes to Special issue of AMBIO: BONUS+ in Support of the Ecosystem Approach to Management in the Baltic Sea
BNI researchers from BNI Sweden, Denmark and Finland contribute with several articles in a new special issue of AMBIO, which provides a synopsis of the results from the projects in the BONUS+ programme 2009-2011.

Research communication needed for the Baltic Sea
Increased information regarding what research says about the state of the Baltic Sea is crucial for politicians in order to take the decisions needed to save the Baltic Sea. That was the key message at a seminar organized by the Baltic Sea Centre at Stockholm University during Almedalsveckan. See the seminar at

Riksdagsseminarium om Östersjöns återställande
Tillsammans med andra Östersjöexperter blev Christoph Humborg, BNI Sverige, inbjuden att presentera den senaste forskningen om Östersjöns övergödning.

International workshop on nutrient and carbon fluxes
BNI closely collaborates with researchers from Cornell University and its College of Agriculture and Life Sciences (CALS), arranging a workshop on "Understanding temporal trends in nutrient and carbon fluxes to coastal oceans: Toward a linking of different modeling approaches", held in New York in October.

Professor Christoph Humborg present the history, state and future of Baltic Sea eutrophication
In an interview, professor Christoph Humborg identifies eutrophication, overfishing and hazardous substances as the major environmental threats facing the Baltic Sea. He also gives a longer presentation regarding the development of Baltic Sea eutrophication.
