Abstract. This study presents a model of chlorophyll and primary production in the pelagic Mediterranean Sea. A 3-D-biogeochemical (OPATM-BFM) was adopted to explore specific system characteristics quantify dynamics key biogeochemical variables over 6 yr period, from 1999 2004. We show that, on basin scale, Sea is characterised by high degree spatial temporal variability terms concentrations. On important horizontal vertical gradients have been observed. According simulations developed...
Ocean ecosystems are subject to a multitude of stressors including changes in ocean physics and biogeochemistry, direct anthropogenic influences. Implementation protective adaptive measures for requires combination observations with analysis prediction tools. These can guide assessments the current state, elucidate ongoing trends shifts, anticipate impacts climate change management policies. Analysis tools defined here as circulation models that coupled biogeochemical or ecological models....
Abstract In the vast Low Nutrient Low‐Chlorophyll (LNLC) Ocean, vertical nutrient supply from subsurface to sunlit surface waters is low, and atmospheric contribution of nutrients may be one order magnitude greater over short timescales. The turnover time Fe N (<1 month for nitrate) further supports deposition being an important source in LNLC regions. Yet, extent which inputs are impacting biological activity modifying carbon balance oligotrophic environments has not been constrained....
Abstract. An updated climatology, based on a comprehensive data set (1911–2009) of temperature, salinity and dissolved oxygen, has been produced for the whole Adriatic Sea with variational inverse method using DIVA (Data-Interpolating Variational Analysis) software. Climatological maps were at 26 levels validated ordinary cross-validation real vs. synthetic temperature–salinity diagram intercomparison. The concept climatology–observation misfit (COM) introduced as an estimate physical...
Building the capacity for monitoring and forecasting marine biogeochemistry ecosystem dynamics is a scientific challenge of strategic importance in context rapid environmental change growing public awareness its potential impacts on ecosystems resources. National Operational Oceanography centres have started to take up this by integrating operational systems. Ongoing activities are illustrated paper presenting examples (pre-)operational biogeochemical systems active Europe North America...
Abstract. The quality of the upgraded version Copernicus Marine Environment Monitoring Service (CMEMS) biogeochemical operational system Mediterranean Sea (MedBFM) is assessed in terms consistency and forecast skill, following a mixed validation protocol that exploits different reference data from satellite, oceanographic databases, Biogeochemical Argo floats, literature. We show MedBFM has been improved previous 10 years. demonstrate set metrics based on GODAE (Global Ocean Data...
The Stokes boundary layer in the turbulent regime is investigated by using large-eddy simulations (LES). Reynolds number, based on thickness of layer, set equal to Re δ = 1790, which corresponds test 8 experimental study Jensen et al . ( J. Fluid Mech. vol. 206, 1989, p. 265). Our results corroborate and extend findings relevant studies: alternating phases acceleration deceleration are correctly reproduced, as sharp transition turbulence, observable at a phase angle between 30° 45°, its...
We present two time series of bottom current and temperature collected 8 m above the seabed on either side a large sediment drift located continental rise Pacific margin Antarctic Peninsula. The mean speed is comparable (6.2 cm s −1 6.1 respectively), but direction differs by about 121°. flow follows bathymetric contour, maximum never exceeds 20 (below typical benthic storm threshold). potential remarkably stable (0.11 ± 0.01°C 0.13 0.02°C at sites). cross-covariance indicates significant...
Abstract. Operational prediction of the marine environment is recognised as a fundamental research issue in Europe. We present pre-operational implementation biogeochemical model for pelagic waters Mediterranean Sea, developed within framework MERSEA-IP European project. The OPATM-BFM coupled core fully automatic system that delivers weekly analyses and forecast maps Sea biogeochemistry. has been working its current configuration since April 2007 with successful execution operational chain...
PERSEUS project aims to identify the most relevant pressures exerted on ecosystems of Southern European Seas (SES), highlighting knowledge and data gaps that endanger achievement SES Good Environmental Status (GES) as mandated by Marine Strategy Framework Directive (MSFD). A complementary approach has been adopted, a meta-analysis existing literature pressure/impact/knowledge summarized in tables related MSFD descriptors, discriminating open waters from coastal areas. comparative assessment...
The Italian Fixed-Point Observatory Network (IFON) integrates well-established coastal and ocean infrastructures (buoys, platforms, moorings, mast etc.), most of them providing real-time multidisciplinary monitoring for a number marine atmospheric variables. Here, we describe the network characteristics then discuss an example its operation during cold spell winter 2012. One goals Flagship Project Ricerca Italiana per il mare (RITMARE) is to create common, validated IFON database able fulfil...
Abstract In this work, we use a set of recent multiyear simulations to develop simplified sea surface height index (SSH). The characterizes the dynamics Ionian upper layer circulation and its links with salinity in Southern Adriatic Aegean Seas during period 1987–2008. analysis highlights covariant behavior between Sea associated mutual zonal exchange water masses different characteristics. Our confirms that variability observed 1987–2008 was driven by Sea. This study supports reinforces...
Abstract. Operational approaches have been more and widely developed used for providing marine data information services different socio-economic sectors of the Blue Growth to advance knowledge about environment.

Data from eight CTD casts and two one-year long current time series collected at 8 60 m above the seafloor of a sediment drift, off Pacific Margin Antarctic Peninsula are presented, with special emphasis on bottom boundary layer dynamics processes relevant to settling re-suspension. The water masses over drift characterized, including also comparison other measurements available that region. south-westward flow along continental rise exhibits strong topographic (bathymetric) control in...
This paper investigates the role of wind forcing and river discharge on a small‐scale shallow embayment: Gulf Trieste. The qualitative quantitative analysis these dominant processes is carried out using high resolution numerical model, initialized forced with experimental data. simulations are focused short‐term transient events, which occurred during stratification season (spring summer). Two significant case studies analyzed in detail: strong event summer flood spring. model output also...
