Decision support system for emergency management of oil spill accidents in the Mediterranean Sea

This paper presents an innovative web-based decision support system to facilitate emergency management in the case of oil spill accidents, called WITOIL (Where Is The Oil). The system can be applied to create a forecast of oil spill events, evaluate uncertainty of the predictions, and calculate hazards based on historical meteo-oceanographic datasets. To compute the oil transport and transformation, WITOIL uses the MEDSLIK-II oil spill model forced by operational meteo-oceanographic services. Results of the modeling are visualized through Google Maps. A special application for Android is designed to provide mobile access for competent authorities, technical and scientific institutions, and citizens

Monitoring and assessment guidelines for marine litter in Mediterranean MPAs

As part of the AMARE project, the main purpose of this report is to provide advice and practical guidance, for establishing programmes to monitor and assess the distribution and abundance of marine litter in MPAs. The present document build on relevant existing monitoring and assessment practices in the Mediterranean, such as the existing monitoring practices in UNEP/MAP and within the Marine Strategy Framework Directive. The proposed strategy (defining the sampling scheme, the environmental compartment to monitor and the protocols to be used) is also following the recommendations of the UN GESAMP report on monitoring marine litter (GESAMP, 2019). In addition, it is based on the experience of ongoing monitoring and assessment activities under various scientific projects in the Mediterranean Sea (CleanSea, Marelitt, Perseus, Marlisco, Ac4forlitter, INDICIT, MEDseaLitter, Plastic Buster MPA, PANACEA, Life projects, etc.), and also considers the available scientific literature.peer-reviewe

Numerical modeling of oil pollution in the Eastern Mediterranean Sea

This chapter presents a summary of major applications in numerical oil spill predictions for the Eastern Mediterranean Sea. Since the trilateral agreement between Cyprus, Egypt, and Israel back in 1997, under the framework of the subregional contingency plan for preparedness and response to major oil spill pollution incidents in the Eastern Mediterranean Sea, several oil spill models have been implemented during real oil pollution accidents and after oil spills that were detected from satellite remote sensing SAR data. In addition, several projects cofinanced by the European Commission addressed particularly issues with oil spill modeling, taking the advantage of developments in operational oceanography, as well as collaboration with the Mediterranean Oceanographic Network for Global Ocean Observing System (MONGOOS), with the European Maritime Safety Agency CleanSeaNet (EMSA-CSN), and Regional Marine Pollution Emergency Response Centre for the Mediterranean Sea (REMPEC). Major oil pollution incidents in the Eastern Mediterranean and the oil spill modeling applications carried out are summarized in this work. Three well-established operational oil spill modeling systems – two of them characterized by different numerical tools MEDSLIK, MEDSLIK II, and the POSEIDON oil spill models – are described in terms of their applicability to real oil spill pollution events, the Lebanon oil pollution crisis in summer 2006, the case Costa Concordia accident, and the spill event associated with the collision of two cargo vessels in the North Aegean Sea in June 2009. Finally, an overview of the present-day capability of Eastern Mediterranean countries in oil spill modeling is provided in this chapter

Microplastics in Mediterranean coastal area: toxicity and impact for the environment and human health

The so-called marine litter, and in particular microplastics (MPs) and nanoplastics (NPs), are ubiquitously distributed and recognised as an emerging risk for the environment and human health. It is known that marine environments are one of the most impacted areas and among them; coastal zones are the most contaminated ones. They are subjected to population pressure, tourism, harbours, desalination plants, marine traffic and fish farms. This review is focused on the Mediterranean Sea, currently considered one hot spot of microplastics pollution in the world, as a consequence of the high number of plastic marine litter generating activities and its characteristic morphology of semi-enclosed sea. MPs and NPs have been detected not only in surface water and water columns but also in sediments, deep seafloor, and biota including fish and seafood for human consumption. Because of this, different European legislation initiatives have been launched during the last years in order to prevent MPs and NPs contamination and to face derived problems. Finally, this review summarises the main problems and shortcomings associated to MPs and NPs analyses such as their identification and quantification or the necessity of standardised protocols.Postprin

Challenges for Sustained Observing and Forecasting Systems in the Mediterranean Sea

The Mediterranean community represented in this paper is the result of more than 30 years of EU and nationally funded coordination, which has led to key contributions in science concepts and operational initiatives. Together with the establishment of operational services, the community has coordinated with universities, research centers, research infrastructures and private companies to implement advanced multi-platform and integrated observing and forecasting systems that facilitate the advancement of operational services, scientific achievements and mission-oriented innovation. Thus, the community can respond to societal challenges and stakeholders needs, developing a variety of fit-for-purpose services such as the Copernicus Marine Service. The combination of state-of-the-art observations and forecasting provides new opportunities for downstream services in response to the needs of the heavily populated Mediterranean coastal areas and to climate change. The challenge over the next decade is to sustain ocean observations within the research community, to monitor the variability at small scales, e.g., the mesoscale/submesoscale, to resolve the sub-basin/seasonal and inter-annual variability in the circulation, and thus establish the decadal variability, understand and correct the model-associated biases and to enhance model-data integration and ensemble forecasting for uncertainty estimation. Better knowledge and understanding of the level of Mediterranean variability will enable a subsequent evaluation of the impacts and mitigation of the effect of human activities and climate change on the biodiversity and the ecosystem, which will support environmental assessments and decisions. Further challenges include extending the science-based added-value products into societal relevant downstream services and engaging with communities to build initiatives that will contribute to the 2030 Agenda and more specifically to SDG14 and the UN's Decade of Ocean Science for sustainable development, by this contributing to bridge the science-policy gap. The Mediterranean observing and forecasting capacity was built on the basis of community best practices in monitoring and modeling, and can serve as a basis for the development of an integrated global ocean observing system

Tracking plastics in the Mediterranean: 2D Lagrangian model

Drift of floating debris is studied with a 2D Lagrangian model with stochastic beaching and sedimentation of plastics. An ensemble of >1010 virtual particles is tracked from anthropogenic sources (coastal human populations, rivers, shipping lanes) to environmental destinations (sea surface, coastlines, seabed). Daily analyses of ocean currents and waves provided by CMEMS at a horizontal resolution of 1/16° are used to force the plastics. High spatio-temporal variability in sea-surface plastic concentrations without any stable long-term accumulations is found. Substantial accumulation of plastics is detected on coastlines and the sea bottom. The most contaminated areas are in the Cilician subbasin, Catalan Sea, and near the Po River Delta. Also, highly polluted local patches in the vicinity of sources with limited circulation are identified. An inverse problem solution, used to quantify the origins of plastics, shows that plastic pollution of every Mediterranean country is caused primarily by its own terrestrial sources.Published151-1624A.
