Monitoring the impact of litter in large vertebrates in the Mediterranean Sea within the European Marine Strategy Framework Directive (MSFD): Constraints, specificities and recommendations
Created: 2017-05-04 09:33:31.176 by: Generation Service
In its decision (20101477/EU) relating to the European Marine Strategy Framework Directive (MSFD, 2008/56/EC), the European Commission identified the following points as focuses for monitoring: (i) 10.1.1: Trends in the amount, source and composition of litter washed ashore and/or deposited on coastlines, (ii) 10.1.2: Trends in the amount and composition of litter in the water column and accumulation on the sea floor, (iii) 10.1.3: Trends in the amount, distribution and composition of micro-particles (mainly microplastics), and (iv) 10.2.1: Trends in the amount and composition of litter ingested by marine animals. Monitoring the impacts of litter will be considered further in 2014. At that time, the strategy will be discussed in the context of the Mediterranean Sea, providing information on constraints, protocols, existing harm and research needed to support monitoring efforts. The definition of targets and acceptable levels of harm must take all factors into account, whether entanglement ingestion, the transport and release of pollutants, the transport of alien species and socioeconomic impacts. It must also reflect on the practical deployment of \"ingestion\" measures (10.2.1). The analysis of existing data will reveal the potential and suitability of some higher trophic level organisms (fish, turtles, birds and mammals) for monitoring the adverse effects of litter. Sea turtles appear to be useful indicator species, but the definition of an ecological quality objective is still needed, as well as research on alternative potential indicator species.

Swordfish harpoon fishery in the Mediterranean Sea: Recent data to implement the Marine Strategy Framework Directive and the EcAp (Ecosystem Approach) process
Created: 2017-05-04 11:13:18.164 by: Generation Service
This paper provides new data on the swordfish harpoon fishery carried out during 1999-2011 in Italian waters (central Mediterranean Sea), concerning fleet structure and its changes over the last decade, spatial distribution of fishing effort and catches, trend of catch rates, size composition of catches as well as fishing of other species. These data were partially used to implement the MSFD Initial Assessment of Descriptor 3 for Italian waters, and could be useful for the forthcoming application of the EcAp (Ecosystem Approach) process, regarding Ecological Objective 3. Swordfish harpoon fishery is a typical artisanal practice, characterized by selective catches as well as by cherished cultural traditions, being one of the most ancient fisheries in the Mediterranean Sea, with lengthy traditions and close links with local culture. Fishing capacity showed a low, stable level during the sampling period. Fishing effort, in terms of days at sea, was more intense in GSA 19 than in GSA 10, whereas CPUE often resulted higher during June and July in GSA 10 due to the occurrence of fish belonging to pairs during the reproduction period. Over the period 1999-2009, the percentage of females larger than L-50 increased up to almost 100% of the catch in both GSA 10 and GSA 19, underlining the high selectivity of this fishing practice, and might be the result of enforcing strict management measures on Mediterranean swordfish stock in recent years. This study also provided some information on the catch of Tetrapturus belone, whose stock is today regarded as data-poor. (C) 2014 Published by Elsevier B.V.

How can operational oceanography products contribute to the European Marine Strategy Framework Directive? The Italian case
Created: 2017-05-04 11:08:39.999 by: Generation Service
Operational oceanography products have been used to define the Marine Strategy Framework Directive (MSFD) good environmental status (GES) relative to the Italian marine ecosystem subregions. Observations include sea surface temperature (SST), winds and chlorophyll Mediterranean Sea satellite products and Italian national tide gauge network winds. These were used to obtain SST seasonal climatology data and trends, 90th percentile of chlorophyll climatology data and SST and wind coastal upwelling indices. Also, Eulerian and Lagrangian circulation models have been used to map the residence time (RT) of Lagrangian particles in the marine subregions, which mimics pollutant dispersion capability at a given location and time.

The RADMED monitoring programme as a tool for MSFD implementation: towards an ecosystem-based approach
Created: 2017-05-04 10:44:00.978 by: Generation Service
In the western Mediterranean Sea, the RADMED monitoring programme is already conducting several of the evaluations required under the Marine Strategy Framework Directive (MFSD) along the Spanish Mediterranean coast. The different aspects of the ecosystem that are regularly sampled under this monitoring programme are the physical environment and the chemical and biological variables of the water column, together with the planktonic communities, biomass and structure. Moreover, determinations of some anthropogenic stressors on the marine environment, such as contaminants and microplastics, are under development. Data are managed and stored at the Instituto Espanol de Oceanografia (IEO) Data Centre that works under the SeaDataNet infrastructure, and are also stored in the IBAMar database. In combination with remote sensing data, they are used to address open questions on the ecosystems in the western Mediterranean Sea.
Operational oceanography for the Marine Strategy Framework Directive: the case of the mixing indicator
Created: 2017-05-04 10:35:57.324 by: Generation Service
In this paper we show that operational oceanography products can be used to develop indicators as required by the Marine Strategy Framework Directive (MSFD). We present a mixing indicator that is calculated using MyOcean Marine Service reanalysis products. Seasonal climatology data of the Brunt-Vaisala frequency (BVF) were computed for 2001-2010 and the vertical mixing coefficient was defined. A vertical mixing indicator was then computed in order to differentiate between different mixing conditions depending on the seasons and differentiating between the shelf and the open ocean in the central Mediterranean Sea.

Commonly, the Baltic Sea is pictured as a proactive region with a long-standing tradition for cooperation and surrounded by the \"greenest\" EU countries. In contrast, southern countries often suffer from the \"Mediterranean Syndrome\" in which the heterogenous socio political situation is given as the \"proof\" that cooperation would not work. The Marine Strategy Framework Directive adopted by European Union in 2008 is an important step towards ecosystem-based marine management and provides a legal document suggesting marine regions as a scale for cooperation. In this paper, we aim to explore stakeholders' perspectives on key factors for good governance at the regional sea level covering the Eastern Baltic States and the south of France. We targeted a broad panel of professionals from different sectors with a political, economic or societal importance in the respective seas. We suggest that Baltic and Mediterranean stakeholders are going through very different stages of governance adjustment fitting the purpose of ecosystem-based marine management. Baltic institutions are well established, which in some way prevents structural analysis of whether the current governance model is the most appropriate reaching GES. In the Mediterranean, the EU strategies faces institutional challenges, which is leading stakeholders to think \"out of the box\" about what is really needed for implementing ecosystem-based marine management for this sea. It is suggested that a golden opportunity exists at present in the Mediterranean to create a regional platform of cooperation, not only to fit the MSFD implementation, but also to improve governance of the Mediterranean Sea and its environmental status.

This article addresses the institutional ambiguity that exists between the European, Regional and Member State levels in the implementation of the Marine Strategy Framework Directive (MSFD). The two main reasons for the emergence of institutional ambiguity are (1) the MSFD being a framework directive and (2) Member States are required to coordinate the implementation of the MFSD through the Regional Sea Conventions. Institutional ambiguity refers to the interference zone between different institutional settings that come together in new policy practices. New rules of the game are needed to bring these institutional settings together and the room to manoeuvre for the actors who negotiate these rules is a defining feature of institutional ambiguity. This article analyses the institutional ambiguity associated with MSFD implementation on the European and regional level for four European Seas: the North Sea, the Baltic Sea, the Mediterranean Sea and the Black Sea. The results indicate different levels of institutional ambiguity in each of the four regions, with the lowest level of ambiguity in the Baltic Sea and the highest in the Mediterranean Sea. Institutional ambiguity also exists on the European level, as coordination efforts have not resulted in clear directions for the implementation of the MSFD as yet. The level of institutional ambiguity is influenced by the relative number of EU member states bordering the particular sea and whether they consider implementation of the MFSD to be urgent. Member States bordering the Mediterranean and the Black Seas lack the support of Regional Sea Conventions in addition to receiving limited direction from the European level. (C) 2011 Elsevier Ltd.

Scientific information on the biodiversity of marine caves in the eastern Mediterranean is limited, especially when considering the extensively studied caves of the north-western and central Mediterranean. Aiming to enhance current knowledge regarding cave communities, this study represents a first assessment of the marine cave biota of the eastern Mediterranean, as defined by the European Union's Marine Strategy Framework Directive (MSFD). Information retrieved from an extensive overview of relevant scientific documents was combined with original data recorded from 23 marine caves in the north-eastern Mediterranean. Our results report a total of 520 taxa recorded in eastern Mediterranean marine caves to date, the majority of which are sponges, polychaetes, rhodophytes, bivalves, fishes, and gastropods. These include several protected, endemic and alien species. However, not all taxonomic groups from different areas have been equally investigated and future studies are expected to increase the number of endemic and alien species. The observed general trend is that the reported species number is generally related to sampling effort and scientific expertise. The most well-studied marine cave communities in the eastern Mediterranean are those of the Aegean Sea (especially its northern sector), which presented the highest number of species, followed by those of the Levantine. Furthermore, our research in Aegean caves revealed numerous new records for the marine cave fauna of the eastern basin, while several species are reported for the first time in a marine cave habitat. The critical need for further scientific research, monitoring, and conservation of this unique ecosystem was highlighted by (i) the presence of certain species endemic to the eastern Mediterranean coupled with a high proportion of alien species, especially in the Levantine Basin, and (ii) marine cave habitat availability in isolated insular areas of the eastern Mediterranean.
