Marine modelling – Baltic Nest Institute

Baltic Nest Institute (BNI) is an international research alliance between Stockholm University Baltic Sea Centre, The Swedish Agency for Marine and Water ManagementAarhus University and the Finnish Environment Institute (SYKE). BNI was established in 2007 to continue the research conducted in the international research programme MARE (1999-2006).

The Baltic Nest Institute is responsible for 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. The main focus of the model is on eutrophication and the flows of nutrients from land to sea. 

Baltic Nest Institute Sweden participates in several national and international projects aiming to understand the environmental problems in the Baltic Sea and show the consequences of different courses of action using marine modelling. Some of these projects are presented below.

 

Destony

BONUS DESTONY

BONUS DESTONY (2018-2020) is one of the BONUS synthesis projects where BNI Sweden participate together with Finnish Environment Institute (SYKE)Aarhus University and Leibniz University for Baltic Sea Research Warnemünde.

The project will identify virtual decision support tools (DSTs) developed to assist ecosystem-based management of the Baltic Sea and its drainage basin, and analyze them against the current and anticipated future needs. 

Climefish

ClimeFish

The aim of the EU Horizon 2020 project ClimeFish is to support sustainable fisheries, enable an increase in European aquaculture production, facilitate employment and regional development in the sectors, and develop forecasting and management tools for adapting to climate change. The project simulate the growth of the most important and the less resilient cultured and wild caught fish and shellfish species in Europe during the RCP4.5 and the 8.5 IPCC scenarios. 

Bluewebs

BONUS BLUEWEBS

BONUS BLUEWEBS (2017-2020) will investigate the development and consequences of novel food webs using innovative data analyses such as big data analytics, cutting edge trait-based ecology and ecological network analysis. The project will provide tools for ecosystem-based management, such as indicators for Marine Strategy Framework Directive descriptors and Bayesian Network based decision support systems. Stockholm University participates in the project together with partners from Finland, Germany, Poland and Latvia.

Balticapp

BONUS BalticAPP

This project studied both the supply and demand of marine ecosystem services across the entire Baltic Sea region in a spatially and temporally detailed manner. The project ran 2015-2018 and included participants from Finland, Denmark, Germany, Sweden and Poland.

BONUS BLUEPRINT

Within the BONUS project BLUEPRINT (2014-2018) the model BALTSEM (BAltic Sea Long-Term large Scale Eutrophication Model) was further developed to include bacterial processes. The project combined field studies, experiments, next-generation sequencing, bioinformatics and modeling.

COCOA - NUTRIENT COCKTAILS IN THE COASTAL ZONE OF THE BALTIC SEA

BONUS COCOA

BONUS COCOA (2014-2017) is an abbrevation for Nutrient cocktail in coastal zones of the Baltic Sea – improving understanding of the transformation and retention of nutrients and organic matter in the coastal zone. BNI Sweden participated in the project with the main purpose to create a database containing basic information of all the Baltic Sea coastal areas and contribute to quantification of the filter function based on empirical data, measurements and models.

But there are still uncertainties about the fluxes and dynamics of phosphorus and their contribution to eutrophication, which was discussed at the HELCOM-EUSBSR workshop where the Baltic Sea Centre participated.

  • 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.
