With escalating pressures from diverse human activities, marine environments are increasingly threatened by cumulative impacts such as biodiversity loss, habitat degradation, and fish stock decline, putting ecosystem sustainability at risk. This research introduces a comprehensive framework to manage counter these impacts, using data-driven ecological modeling tools realistically capture ecosystems' responses complex human-induced pressures, thereby supporting informed effective...
The coastal fishery made in the Eastern Black Sea area satisfies country's major demand for fish and seafood.The has also attracted attention with increasing international oil gas exploration activities carried on recently.Large capacity tankers pass through this sea to carry crude petrochemical products while existing planned hydrocarbon transportation pipelines increase cargo traffic as well.Therefore new environmental risks are threatening region's ecosystem due potential events such...
This paper explores the problem of allocation potential places refuge for a ship in distress along Estonian coast Gulf Finland balancing advantage affected and environment resulting from bringing into place refuge.The integrated oil accident response simulation (PISCES II, ArcGis spatial modeling tools Bayesian Belief Networks) proved to be instrumental operational decision support case hypothetical accident.The knowledge ecological sensitivity coastal sea is used estimate probability...
The aim of this paper is to assess the potential oil spill related ecological risk for southern Gulf Finland coastal waters using Bayesian Belief Network (BBN) methodology.The BBN prior probabilities were obtained from knowledge on spatial variability in sensitivity ecosystem Finland.The data represented three different elements: EU Habitat Directive Annex 1 habitats and associated habitat forming species, Birds birds seals.Information bird, seal layers integrated into a single measure...
Under an increasing maritime transport in the Baltic Sea, and especially Gulf of Finland, possibility environmental harm accidents due to shipping pressure is growing. To counteract risks, adequate measures for accident prevention mitigation consequences are critically important. The Finland Mandatory Ship Reporting System (GOFREP) a complex socio-technical safety management system that has been efficient operation since 2004 it open further improvement development. However, not explicitly...
According to International Maritime Organization (IMO), the Baltic Sea Area has some of densest maritime traffic in world. The was designated a Particularly Sensitive (PSSA) at IMO Marine Environment Protection Committee's 53rd session July 2005. Mandatory Ship Reporting System Gulf Finland Traffic (GOFREP) established by 2003 and been operation since 2004. objective this study progress is 1) outline hierarchical structure navigation safety management system from European ship onboard level...
The Baltic Sea is a unique and sensitive brackish-water ecosystem vulnerable to damage from shipping activities. Despite high levels of maritime safety in the area, there continued risk oil spills associated harmful environmental impacts. Achieving common situational awareness between spill response decision makers other actors, such as merchant vessel Vessel Traffic Service center operators, an important step minimizing detrimental effects. This paper presents Next-Generation Smart Response...
The Baltic Sea Area is a globally unique and sensitive brackish-water ecosystem. More than 2,000 ships are on the way in an average day. was designated as Particularly Sensitive (PSSA) at IMO Marine Environment Protection Committee's 53rd session July 2005. Contemporary hierarchical maritime navigation safety management system from global to local level considered basis for implementation of System Theoretic Accident Model Processes (STAMP) approach architecting control system. This paper...

Global, regional and national policies regulations are providing incentives to reduce greenhouse gas (GHG) emissions in ports, the first step this effort is obtain a detailed overview of main sources emissions. The rapid developments port GHG mapping have led need for case study assess effectiveness practical use these methodologies suggest best practices ports just starting process. Here, we present current state art assessment ports. This analysis enabled us identify most promising an...
Intensification and diversification of human-induced pressures in marine ecosystems have raised concerns over several sustainability-diminishing consequences, such as hypoxia overexploitation resources. We present the PlanWise4Blue tool (PW4B), which assesses cumulative effects multiple on nature assets. In order to express sensitivity different assets a plethora pressure combinations, meta-analysis based published literature available datasets was performed calculate set standardized effect...
System is smart if its negative feedback loop constantly working to reduce the difference between actual and desired states (goals) of system. Goals itself should be SMART - specific, measurable, agreed upon, realistic time-based. A precondition for management availability a based regulatory measure that can move system towards state. Fishing fleet overcapacity associated low economic resilience impose high political pressure increase short-term fishing opportunities at expense future...
The context of fisheries management, according to recent studies, tends be complex, uncertain and controversial it cannot adequately addressed based on work done within the "linear" science-policy interface (SPI).It is believed that moving towards a more participatory "collaborative" SPI model would favourimplementation efficient economic incentives reduce fishing fleet capacity bring actual mortality closer levels considered sustainable.Focusing research basically fish biology stock...
This paper discusses possible solutions to the problem of integrating fishery management into process Maritime Spatial Planning (MSP) and exemplifies issue by analyzing potential solution for place based Gulf Riga herring in Pärnu Bay (Baltic Sea).According latest scientific advice, total landings are above Maximum Sustainable Yield (MSY) level from Precautionary Approach point view, stock is harvested unsustainably.According Ecosystem fisheries, fishing capacity should be balanced with...
Uncertainty is an endemic condition of the Baltic Sea herring (Clupea harengus membras, L) fishery management.It a exacerbated by fishing fleet overcapacity and consequent exploitation stock at level believed to be unsustainable.Some sources uncertainty are mainly related biology technique: unsolved problem assessment management units, recruitment-environment relationship reduction in mean weights-at-age, uncertain ageing fish, unaccounted mortality caused fish selection through trawl...
Oil spills pose significant threats to marine ecosystems, and while existing tools simulate spill dispersion predict impacts, they often lack full integration of accident specifics, detailed drift simulations, thorough impact analyses. This paper presents the EcoSensitivity decision support system, a comprehensive platform designed improve oil responses by integrating immediate cumulative environmental assessments. The system addresses these gaps combining Accidental Damage Spill Assessment...
The Baltic Sea Regional Advisory Council (BS RAC) was set up in March 2006 with the aim of contributing to sustainable use fishery resources under EU Common Fisheries Policy.The BS RAC can be seen as an international boundary organization mixing scientific and political elements, mediating between institutions science politics.This paper attempts explore performance a producing recommendations Commission.Bayesian Belief Network (BBN) methodology is used identify uncertainty reducing capacity...
Internet GIS is defined in literature as a research and application area that utilizes the internet to facilitate access, processing, dissemination of geographic information spatial analysis knowledge.Boundary-GIS geoportal based on ESRI ArcGIS Silverlight technology serves platform for developing different project related web applications.It concept collaborative (participatory) processes with objectives: (1) capture knowledge later use (identifying mapping resources competing human uses),...
According to EU Directive establishing a framework for Maritime Spatial Planning (MSP) the main purpose of MSP is promote sustainable development and identify utilization maritime space different sea uses as well manage spatial conflicts in marine areas. The offshore wind energy production considered be one drivers Baltic Sea Region. However, impact on navigational safety from renewable installations (OREI) should assessed taken into account processes. In course implementation INTERREG BSR...
