MONAS, the HELCOM Monitoring and Assessment Group, holds its 19th meeting in Helsinki 19-22 November. MONAS looks after one of HELCOM’s key tasks by assessing trends in threats to the marine environment, their impacts, the resulting state of the marine environment, and the effectiveness of adopted measures. This work forms the basis for the work of HELCOM’s other main groups, and helps to define the need for additional measures. HELCOM MONAS aims to ensure that HELCOM’s monitoring programmes are efficiently used through horizontal co-ordination between the Commission’s five permanent working groups. BNI Participation * MONAS is chaired by Prof. Anna Stiina Heiskanen Other BNI researchers part of regular MONAS meetings are among others Bo Gustafsson and Jacob Carstensen , but many BNI researchers are active in the group´s work.

The understanding of the value and function of the ecosystem services provided by the Baltic Sea is still limited. For that reason HELCOM , the Swedish Environmental Ministry , UNEP , Stockholm Resilience Centre and the Nordic Council of Ministers will organize a workshop on the economic valuation of marine and coastal ecosystem services in the Baltic Sea. BNI contribution Fredrik Wulff , will present Challenges of reaching a clean Baltic Sea In addition, research results from the BalticSTERN report and project , where Marmar Nekoro , Berit Hasler and others at BNI have contributed, is presented.

4 October 2013, 10.00 AM - 2.00 PM, Susa Niiranen will defend her PhD-thesis "Multiple forces drive the Baltic Sea food web dynamics and its reponse to environmental change".Opponents: Prof. Mike Elliott (University of Hull), and the examination committee are Prof. Agneta Andersson (University of Umeå), Dr. Joakim Hjelm (SLU) and Dr. Geir Ottersen (University of Oslo).Understanding multiple drivers key challengeUnderstanding the interaction of multiple drivers and their compounded effects on ecosystem dynamics is a key challenge for marine resource management. The Baltic Sea is one of the world´s seas most strongly impacted, by effects from both human activities and climate. In the late 1980´s changes in climate, in combination with intensive fishing, initiated a reorganization of the Central Baltic Sea (CBS) food web resulting in the current sprat-dominated state. In the future, climate change is projected to cause drastic changes in hydrodynamic conditions of the world oceans in general, and the Baltic Sea in particular.The strength of the new BalticProWeb In this thesis, CBS food web responses to the combined effects of fishing, nutrient loads and climate were tested for the past (1974-2006) and projected into the future (2010-2098). A new food web model for the CBS (BaltProWeb) was developed using extensive monitoring data across trophic levels. This model described the past food web dynamics well, and was hence also used for future (2010-2098) projections. Different ensemble modeling approaches were employed when testing the food web response to future scenarios.Management influence food web dynamicsThe results show that regardless the climate change, the management of nutrient loads and cod fishing are likely to determine the food web dynamics and trophic control mechanisms in the future Baltic Sea. Consequently, the variation in the food web projections was large, ranging from a strongly eutrophied and sprat-dominated to a cod-dominated CBS with eutrophication levels close to today´s values. The results also suggest a potential risk of abrupt ecosystem changes in the future CBS, particularly if the nutrient loads are not reduced. Finally, the studies illustrate the usefulness of the ensemble modeling approach, both from the perspective of ecosystem-based management as well as for studying the importance of different mechanisms in the ecosystem response.Further readingDownload and read Susa Niiranen´s comprehensive summary of her PhD thesis hereDownload and read the papers included in the thesis below:Ecosystem flow dynamics in the Baltic Proper-Using a multi-trophic dataset as a basis for food-web modellingUncertainties in a Baltic Sea Food-Web Model Reveal Challenges for Future ProjectionsBiological ensemble modeling to evaluate potential futures of living marine resourcesCombined effects of global climate change and regional ecosystem drivers on an exploited marine food webThe potential risk of regime shifts and changes in ecosystem dynamics in the future Baltic Sea

The Gulf of Finland (GoF) 2014 year is targeting on better understanding GoF as a system and
production of new information on the status of the Gulf of Finland. The aim of the modelling workshop was to plan the GoF Year research activity. BNI ParticipationInvolved BNI researchers from BNI Finland and Sweden were: Kai Myrberg (chair of the workshop), Petri Ekholm presenting "Principles of watershed modeling" Alexander Sokolov presenting "Principles of database, modern methods of data processingLetizia Tedesco (rapporteur for the group on Eutrophication process)Scientific topics, where
modeling tools are needed, included i) description of the eutrophication process, ii) maritime
safety, especially in winter conditions, iii) fish modeling, and iv) modeling of climate change
The workshop aimed to:
establish linkages between groups focusing on modelling, observations, data
assimilation, prediction and service provision;
finding gaps in knowledge and weaknesses in our ability to observe state of the Gulf
of Finland, generate products and strengthen modeling capabilities and;
outline observational needs for models.
of the workshop were:a review of the current state-of-the-art research, gaps and advances in GoF
observations, modeling, data assimilation and prediction;
action items with identified partners on how to coordinate overlapping interests,
close gaps in knowledge, and enhance networking between groups; and
plan for the coordinated observational campaignsDownload more information and the program here
