Baltic Nest Institute

Baltic Nest Institute

The Baltic Nest Institute host the Nest system, a decision support system aimed at facilitating adaptive management of environmental concern in the Baltic Sea. Nest can be used to calculate required actions needed to attain politically agreed targets for the Baltic Sea ecosystem. By modeling the entire drainage area, Nest is a novel tool for implementing the ecosystem approach in a large marine ecosystem. The main focus of the model is on eutrophication and the flows of nutrients from land to sea. Reducing the nutrient input to the sea and thus decreasing the negative environmental impacts is a politically prioritized area of international cooperation.

Baltic Nest Institute can contribute to this process by formulating policies that are fair, transparent and cost-efficient. The main target group for the Nest Decision Support System is HELCOM and regional water directors in the riparian countries.

  • Regime shifts in the Northern Benguela ecosystem 2016-03-14 A new article written by BNI researcher Maciej T. Tomczak and Johanna J. Heymans from the Scottish Marine Institute explains how increased fishing and climate drivers during the last 50 years have led to regime shifts, with reorganized ecosystem structure and changes in the main demersal species.
  • BONUS pilot workshop on scenarios 2016-01-28 The objective of the workshop is to take the first steps to explore and develop harmonized storylines for future developments of multiple regional drivers and pressures that affect the Baltic Sea and that can be associated with readily available global climate and socioeconomic scenarios (RCPs and SSPs [1]).
  • Vårutflykt till solig udde i havet Changing seasonality of the Baltic Sea 2015-12-15 Summer season in the Baltic Sea starts earlier. The number of days with sea water warmer than 17°C have almost doubled over the past 30 years. The productive season has also been prolonged. These findings are based on satellite data and the results demonstrate how such indicators of seasonality can be used to detect long-term changes.

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.
