“…The maximum concentrations were observed in the plume area of PV, Giralda and Canal Bianco in the western zone of SG, in front of the Bonello canal inlet and in the eastern zone, which was under the influence of PG. In the eastern sheltered zone of the lagoon nitrate and phosphate concentrations were high through the year leading to conditions which in combination with the slow water renewal favoured the macroalgal blooms and subsequent dystrophy, as was experimentally observed by Viaroli et al (2001Viaroli et al ( , 2006. In the southern part of the lagoon, along the sand barrier and within the clam farming area, relatively high concentrations of ammonium were found, which probably depend on clam metabolism, since the model considers the findings of Bartoli et al (2001b) concerning ammonium production by clams.…”

“…Precipitation has an annual value between 500 and 600 mm that does not affect considerably the SG water balance. Previous investigations on SG hydrodynamics indicated that the lagoon can be partitioned into three zones Viaroli et al, 2006). The central part not only is mainly dominated by the AS but is also considerably influenced by the freshwater delivered from PV and minor canals.…”

“…SG has a triangular shape, maximum length of 11 km, maximum width of 5 km, with a surface area of 26 km 2 , an average depth about 1.5 m, a volume of approximately 39 millions m 3 and a time variable bathymetry and boundaries (O'Kane et al, 1992;Simeoni et al, 2000;Viaroli et al, 2006). The basic hydrodynamic forcing on SG is linked with the tidal dynamics of Adriatic Sea (AS), since the lagoon is connected with the adjacent sea by two mouths which at present are of equivalent sizes of about 900 m. Tidal amplitudes in SG vary up to 0.9 m. The freshwater inputs to SG are mainly from Po di Volano (PV) (about 350 millions m 3 y -1 ) and Po di Goro (PG), at least until 1994 when the PG discharge was considerably reduced because it started to be humanregulated by sluices (Bencivelli, 1998).…”

Integrated modelling in coastal lagoons: Sacca di Goro case study

A coupled 3D hydrodynamic-biogeochemical model was developed and implemented for the Sacca di Goro coastal lagoon. The model considers nutrient and oxygen dynamics in water column and sediments. Among the biological elements, phytoplankton, zooplankton, bacteria, Ulva sp. and commercial shellfish (Tapes philippinarum) were taken into consideration. Nutrients fluxes from the watershed and open sea, as well as atmospheric inputs, heat flux, light intensity and wind shear stress at the water surface constituted the model forcing functions.The comparison of numerical results with available measurement data indicated that the model was able to capture the essential dynamics of the lagoon. This model has also been used to estimate clam productivity and its impacts on water quality and lagoon properties.

“…Published scientific results have clearly shown the role of nitrogen as a determining factor in the control of proliferation of marine green algae (Ulva sp.) whether in Brittany or at other sites of coastal blooms in the world (Piriou et al, 1991; Contribution of livestock to N cascade Viaroli et al, 2006). In 'green algae catchment areas', where action plans have been implemented (Lieue de Grève, SaintBrieuc bay, Concarneau and Douarnenez basins, all located in Brittany), nitrogen from agriculture accounts for practically the totality of nitrogen flows reaching the ocean, whereas treated waste water accounts for only about 5%, as most water waste treatment plants now include denitrifying treatments.…”

Seagrass meadow degradation and loss is one of the major threats to fish biodiversity in coastal marine and lagoon ecosystems in the Mediterranean. Pipefishes and seahorses (family Syngnathidae) are particularly affected by loss of seagrass meadows and other structured habitats, on which they rely for survival and reproduction. Despite their charismatic appearance and peculiar behaviour, their habitat ecology is still poorly understood in Mediterranean coastal waters. This study focuses on syngnathid assemblage composition and diversity in the shallow waters of the Venice lagoon (Italy), aiming at highlighting habitat preferences and providing insights into the conservation of biodiversity in these ecosystems. Generalized Additive Models were used in order to disentangle the potential effect of habitat typologies and different architectures of seagrass meadows from that of other environmental parameters. Most abundant taxa and whole syngnathid assemblage indicators were positively associated with seagrass meadows. Only few species, however, were seagrass specialists in shallow waters, and preferred meadows with taller canopies. Despite that, other structured habitats including short‐leaved seagrass meadows and macroalgal beds were important for some species and overall assemblage diversity. Managers in Mediterranean coastal lagoons should thus limit human pressures that lead to the depletion of seagrass meadows, with particular attention to long‐ and broad‐leaved species in less confined areas. Nevertheless, syngnathid assemblages would benefit from the preservation and restoration of the overall habitat diversity characterizing shallow waters in coastal lagoon. Future studies should aim at investigating the potential role of habitats at greater depths in supporting syngnathids.
