    Description: This paper discusses a methodology where geo-spatial analysis tools are used to quantify risk derived from anthropic activities on habitats and species. The method has been developed with a focus on simplification and the quality of standard procedures set on flora and fauna protected by the European Directives. In this study case, the DPSIR (Drivers, Pressures, State, Impacts, Responses) is applied using spatial procedures in a geographical information system (GIS) framework. This approach can be inserted in a multidimensional space as the analysis is applied to each threat, pressure and activity and also to each habitat and species, at the spatial and temporal scale. Threats, pressures and activities, stress and indicators can be managed by means of a geo-database and analyzed using spatial analysis functions in a tested GIS workflow environment. The method applies a matrix with risk values, and the final product is a geo-spatial representation of impact indicators, which can be used as a support for decision-makers at various levels (regional, national and European).

    Description: The action of propeller-induced jets on the seabed of ports can cause erosion and the deposition of sediment around the port basin, potentially significantly impacting the bottom topography over the medium and long term. If such dynamics are constantly repeated for long periods, a drastic reduction in ships’ clearance can result through accretion, or the stability and duration of structures can be threatened through erosion. These sediment-related processes present port management authorities with problems, both in terms of navigational safety and the optimization of management and maintenance activities of the port’s bottom and infrastructure. In this study, which is based on integrated numerical modeling, we examine the hydrodynamics and the related bottom sediment erosion and accumulation patterns induced by the action of vessel propellers in the passenger port of Genoa, Italy. The proposed new methodology offers a state-of-theart science-based tool that can be used to optimize and efficiently plan port management and seabed maintenance.

    Description: The sensitivity of the dynamics of the Mediterranean Sea to atmospheric pressure and free surface elevation formulation using NEMO (Nucleus for European Modelling of the Ocean) was evaluated. Four different experiments were carried out in the Mediterranean Sea using filtered or explicit free surface numerical schemes and accounting for the effect of atmospheric pressure in addition to wind and buoyancy fluxes. Model results were evaluated by coherency and power spectrum analysis with tide gauge data. We found that atmospheric pressure plays an important role for periods shorter than 100 days. The free surface formulation is important to obtain the correct ocean response for periods shorter than 30 days. At frequencies higher than 15 days􀀀1 the Mediterranean basin’s response to atmospheric pressure was not coherent and the performance of the model strongly depended on the specific area considered. A large-amplitude seasonal oscillation observed in the experiments using a filtered free surface was not evident in the corresponding explicit free surface formulation case, which was due to a phase shift between mass fluxes in the Gibraltar Strait and at the surface. The configuration with time splitting and atmospheric pressure always performed best; the differences were enhanced at very high frequencies.

    Description: A high resolution set-up of a z-level ocean model has been implemented in the Adriatic Sea to investigate the impact of the Levantine Intermediate Water on the Adriatic Sea circulation and dense water formation. The period under investigation starts at the beginning of 2000 and ends at the end 2007. A twin experiment is performed in which the southern boundary conditions are derived from two different operational systems in the Mediterranean Sea. It is shown that the quantity and the characteristics of the Levantine Intermediate Water in the Mediterranean model introduced at the southern boundary may significantly impact the amount of the dense water formed in the Southern Adriatic and the accuracy of the model simulation even in the Northern Adriatic.

    Description: The impact of tides in the circulation of the Adriatic Sea is investigated by means of a nested baroclinic numerical ocean model. Tides are introduced using a modified Flather boundary condition at the open edge of the domain. The results show that tidal amplitudes and phases are reproduced correctly by the baroclinic model and tidal harmonic constants errors are comparable with those resulting from the most consolidated barotropic models. Numerical experiments were conducted to estimate and assess the impact of (i) the modified Flather lateral boundary condition; (ii) tides on temperature, salinity, and stratification structures in the basin; and (iii) tides on mixing and circulation in general. Tides induce a different momentum advective component in the basin, which in turn produces a different distribution of water masses in the basin. Tides impact on mixing and stratification in the River Po region (northwestern Adriatic) and induce semidiurnal fluctuations of salinity and temperature, in all four seasons for the former and summer alone for the latter. A clear presence of internal tides was evidenced in the northern Adriatic Sea basin, corroborating previous findings.

    Description: The use of Multi-model Super-Ensembles (SE) which optimally combine different models, has been shown to significantly improve atmospheric weather and climate predictions. In the highly dynamic coastal ocean, the presence of small-scales processes, the lack of real-time data, and the limited skill of operational models at the meso-scale have so far limited the application of SE methods. Here, we report results from state-of-the-art super-ensemble techniques in which SEPTR (a trawl-resistant bottom mounted instrument platform transmitting data in near real-time) temperature profile data are combined with outputs from eight ocean models run in a coastal area during the Dynamics of the Adriatic in Real-Time (DART) experiment in 2006. New Kalman filter and particle filter based SE methods, which allow for dynamic evolution of weights and associated uncertainty, are compared to standard SE techniques and numerical models. Results show that dynamic SE are able to significantly improve prediction skill. In particular, the particle filter SE copes with non-Gaussian error statistics and provides robust and reduced uncertainty estimates.

    Description: INGV is responsible for the operational production of the physical component of the Mediterranean Sea Monitoring and Forecasting Centre (Med-MFC) of the Copernicus Marine Service Monitoring System (CMEMS). The system was implemented in 2000 by the INGV National Group of Operational oceanography (GNOO) and has been developed in years thanks to a number of European projects. The Med-MFC is a coupled hydrodynamic-wave model with data assimilation component with a resolution of 1/16°. The model solutions are corrected by the variational assimilation (based on a 3DVAR scheme) of Temperature and Salinity vertical profiles (from ARGO, CTD, XBT and Gliders observations) and along track satellite Sea Level Anomaly (SLA) observations. In order to meet the requirements for Copernicus Marine Service Phase I the increase of the horizontal (to 1/24°) and vertical resolution of the hydrodynamic component of Med-MFC has been planned. The major improvements expected from this development are the following: 1) to better resolve the mesoscale processes in the Mediterranean region where the Rossby radius of deformation is about 12-15 km (1/24° is about 4-5 km); 2) to resolve the tidal forcing at Gibraltar, entering from the Atlantic into the Mediterranean, known to provide about 30% amplitude of the tidal signal in the Mediterranean; 3) to better resolve vertical mixing processes.
