Abstract. The Oder/Szczecin Lagoon is one of the largest Baltic Sea lagoons and subject to very high nutrient loads from Oder/Odra River. For our study, we employ a modified, high-resolution 3D ecosystem model specifically adapted for this shallow lagoon. demonstrates stable reliable performance over 25 years simulation, enabling detailed assessment lagoon processes under various scenarios. Our simulations indicate that changes in riverine inputs have an immediate impact on lagoon’s water...
To assess the impact of implementation Baltic Sea Action Plan (BSAP) on future environmental status Sea, already available uncoordinated multi-model ensemble simulations for region 21st century were analyzed. The scenario driven by regionalized global general circulation model (GCM) data using several regional climate system models and forced various greenhouse gas emission air- river-borne nutrient load scenarios following either reference conditions or BSAP. estimate uncertainties in...
Following earlier regional assessment studies, such as the Assessment of Climate Change for Baltic Sea Basin and North Region Assessment, knowledge from available literature about future scenario simulations biogeochemical cycles in their uncertainties is assessed. Uncertainties these projections are caused by climate model (including global models experimental setup), unknown nutrient load greenhouse gas emissions (or concentrations) natural variability. The determination reduction...
Intensive agriculture and densely populated areas represent major sources of nutrient pollution for European inland coastal waters, altering the aquatic ecosystems affecting their capacity to provide ecosystem services support economic activities. Ambitious water policies are in place Union (EU) protecting restoring under Water Framework Directive Marine Strategy Directive. This research quantified current pressures point diffuse nitrogen phosphorus emissions fresh waters (2005–2012),...
A novel pan-European marine model ensemble was established, covering nearly all seas under the regulation of Marine Strategy Framework Directive (MSFD), with aim providing a consistent assessment potential impacts riverine nutrient reduction scenarios on eutrophication indicators. For each sea region, up to five coupled biogeochemical models from institutes over Europe were brought together for first time. All systems followed harmonised scenario approach and ran two simulations, which...
Eutrophication is one of the most important anthropogenic pressures impacting coastal seas. In Europe, several legislations and management measures have been implemented to halt nutrient overloading in marine ecosystems. This study evaluates impact freshwater control on higher trophic levels (HTL) European ecosystems following descriptors criteria as defined by Marine Strategy Framework Directive (MSFD). We used a novel pan-European modeling ensemble fourteen HTL models, covering almost all...
The pre-eutrophic state of marine waters is generally not well known, complicating target setting for management measures to combat eutrophication. We present results from an OSPAR ICG-EMO model assessment simulate the North-East Atlantic waters. Using ecosystem ensemble combined with observation-based weighting method we derive sophisticated estimates key eutrophication indicators. Eight modelling centres applied same riverine nutrient loads, atmospheric deposition rates and boundary...
A full re-calculation of Water Framework Directive reference and target concentrations for German coastal waters the western Baltic Sea is presented, which includes a harmonization with HELCOM Action Plan (BSAP) targets. Further, maximum allowable nutrient inputs (MAI) in rivers catchments are suggested. For this purpose spatially coupled, large scale integrative modeling approach used, links river basin flux model MONERIS to ERGOM-MOM, three-dimensional ecosystem Sea. The years around 1880...
High riverine nutrient loads caused poor water quality, low transparency and an unsatisfactory ecological status in the Szczecin (Oder) Lagoon, a trans-boundary at southern shore of Baltic Sea. Total annual N (P) into lagoon raised 20th century from approx. 14,000~t~TN (1,000~t~TP) to 115,000~t~TN (10,500~t~TP) 1980ties declined about 56,750~t~TN (2,800~t~TP) after 2010. Nutrient concentrations, (Secchi depth) chlorophyll-a showed positive response reduced Polish eastern lagoon. This was not...
Abstract. Oxygen is a key indicator of ecosystem health and part environmental assessments used as tool to achieve healthy ocean. are mostly based on monitoring data that spatially temporally limited, although efforts have increased. This leads an incomplete understanding the current state ongoing trends oxygen situation in oceans. Ocean models can be overcome spatial temporal limitations provide high-resolution 3D but rarely for policy-relevant assessments. In Baltic Sea where long history...
Abstract The European Biodiversity Strategy asks EU Member States for an assessment, mapping and valuing of Ecosystem Services (ES). While terrestrial ES concept is advanced different tools are available, they largely lacking coastal marine systems. We develop a stepwise methodological process to assess in systems which we name Marine Assessment Tool. applied it two large Baltic lagoons, the Szczecin Curonian Lagoons demonstrating quantitative qualitative assessment approach. Firstly,...
Biological long-term data series in marine habitats are often used to identify anthropogenic impacts on the environment or climate induced regime shifts. However, particularly transitional waters, environmental properties like water mass dynamics, salinity variability and occurrence of oxygen minima not necessarily caused by either human activities change can attenuate mask apparent signals. At first glance it very seems impossible interpret strong fluctuations e.g. abundances species...
Mussel farming, compared to marine finfish aquaculture, represents an environmentally friendly alternative for a high quality protein source and can at the same time be measure remove excess nutrients in eutrophic areas. As such, it is considered as promising 'blue growth' potential promoted within European Union. To expand mussel new regions have because there are multiple usages, spatial limitations occur coastal The brackish Baltic Sea might expansion of aquaculture. This study focusses...
We combine historical and recent monitoring data with modeling to get a better insight into water quality development of the large Oder/Szczecin Lagoon at German/Polish border in southern Baltic Sea region especially role macrophytes. Data indicates that system is eutrophic for centuries naturally system. During last decades, external nutrient loads decreased but still keep state. The systems primary production limited by light nitrogen cannot be sufficiently managed load reductions....
The Systems Approach Framework with an integrated Ecological-Social-Economic assessment was applied to address the issue of zebra mussel (Dreissena polymorpha) farming in large Oder (Szczecin) Lagoon, southern Baltic Sea. Heavy eutrophication hampers use lagoon and is considered as new potential measure improve water quality. Three alternative scenarios were developed interaction local stakeholders: 1) production mussels fresh feed meal on a commercial basis seemed not profitable, because...
Abstract For many coastal areas including the Baltic Sea, ambitious nutrient abatement goals have been set to curb eutrophication, but benefits of such measures were normally not studied in light anticipated climate change. To project likely responses on eelgrass ( Zostera marina ), we coupled a species distribution model with biogeochemical model, obtaining future water turbidity, and wave for predicting hydrodynamics area. Using this, was modeled different combinations scenarios wind...
Finding suitable places to establish a mussel farm is challenging, as many aspects like growth, clearance effect and the risk of low oxygen conditions, have be considered. We present tailor-made approach, combining field experiments with spatially explicit model tool, support planning process. A case study was set up in German part Szczecin (Oder) Lagoon (Baltic Sea), it shows all typical eutrophication problems has strong need high potential for nutrient retention measures. Farming zebra...
Abstract Bottom trawling disturbance and hypoxia are affecting marine benthic habitats worldwide. We present an approach to predict their effects on communities, use the estimate state, biomass relative carrying capacity, of Baltic Sea at local, habitat, regional scale. Responses both pressures expected depend longevity fauna, which is predicted from data 1558 locations. find that communities in low-salinity regions mostly consist short-lived species, are, our model, more resilient than...
