BONUS+ projects


BONUS+ projects' key results to policymakers

BONUS+ briefing documents for policymakers (publishing date 24 October 2011).

A total of 16 projects involving over 100 research institutes and universities were funded (totaling EUR 22 million) through a joint call BONUS+ in 2007. It set out to test the mechanisms of collaboration among the national funding institutions. 

In 2011, during their third and final project year, analysis of the obtained data and compilation of the research outputs are ongoing. The results of the projects were presented at the Baltic Sea Science Congress Joint research efforts for sustainable ecosystem management on 22-26 August 2011 in St. Petersburg.

The BONUS Forum on 24 October 2011 in Gdansk, Poland showcased the BONUS+ projects' key findings and next steps to decionmakers.

Works to separate the effects of climate change and human pressures on the coastal ecosystems by combining outputs of the regional climate scenarios and simulating the drainage basin processes

Tests strategies for exploring and establishing causal links of pollutants, effects and status of coastal fish populations

Assesses the genetic diversity situation in several Baltic key species and identifies the most significant pressures, investigates new ways to incorporate genetic biodiversity information into an ecosystem-based management of the Baltic Sea

Employs advanced technology and novel combinations of approaches to develop a predictive model of gas accumulation and emission under realistic scenarios of climate change and eutrophication. It aims to understand how climate change and long-term eutrophication affect the accumulation and emission of methane and hydrogen sulfide from the seabed to the water column and atmosphere

Attempts to establish the first-ever complete carbon budget of the Baltic Sea. Investigates how climate change and human impact alternate carbon fluxes in the ecosystem

Examines how to make shipping, as well as offshore and coastal engineering activities environmentally safer by using new knowledge on semi-persistent surface currents to avoid maritime activities where, in case of a spill, dangerous substances can very probably be washed to the most vulnerable areas

Tests possible cascading effect of comb jelly on the plankton foodweb in the Baltic - predation on cod eggs and larvae, depletion of plankton-eating fish food resources, changes in water clarity eventually leading to a regime shift of the whole system

Develops tools needed to detect and understand human-induced pressure on the Baltic Sea ecosystem based on a broad range of biological effects of pollution


Builds a complex modeling system dedicated entirely to untangling the combined effects of eutrophication and climate change in the Baltic Sea

Estimates the required nutrient reduction in the Baltic region to maintain a healthy sea ecosystem taking into account future climate changes; synthesises information at an ecosystem scale and enriches the knowledge on processes leading to hypoxia, and the role the sediments and the benthic animals play in recycling nutrients

Constructs an integrated risk analysis of ecosystem management in the Gulf of Finland related to fisheries, eutrophication, oil spills, dioxin risks related to the consumption of herring, and climate change

Develops scenarios of the Baltic Sea development to the end of the 21st century by establishing the links between marine sediment markers and conditions in the sea, reconstructing the 6000 year development of the marine system based on these sediment proxies

Develops powerful, precise and cost-efficient methods for spatial prediction of the biological properties of coastal underwater habitats, and combines predictive models and scenarios of human pressures to assess effects on coastal ecology


Analyses the societal conditions for the effective protection of the Baltic Sea at national, macro-regional and the EU levels, using an interdisciplinary framework

Develops and applies the modeling and decision making support tool to settle eutrophication over the entire Baltic Sea drainage basin

Integrates social and natural science approaches to improve our understanding of the structures and processes that shape the governance of environmental risks and suggests a normative framework for improving environmental risk governance in the Baltic Sea
