Connectivity patterns of coastal fishes following different dispersal scenarios across a transboundary marine protected area (Bonifacio strait, NW Mediterranean)

The Strait of Bonifacio constitutes one of the rare transboundary Marine Protected Areas (MPA) of the Mediterranean Sea (between Sardinia, Italy and Corsica, France). Based on the hypothesis that no-take zones will produce more fish larvae, compared to adjacent fished areas, we modeled the outcome of larvae released by coastal fishes inside the no-take zones of the MPA in order to: (i) characterize the dispersal patterns across the Strait of Bonifacio; (ii) identify the main potential settlement areas; (iii) quantify the connectivity and the larval supply from the MPAs to the surrounding areas. A high resolution hydrodynamic model (MARS 3D, Corse 400m) combined to an individual based model (Ichthyop software) was used to model the larval dispersal of fish...

Are litter, plastic and microplastic quantities increasing in the ocean?
Provedor de dados: 5
Autores: Galgani, Francois; Brien, Aleke Stoefen-o; Weis, Judith; Ioakeimidis, Christos; Schuyler, Qamar; Makarenko, Iryna; Griffiths, Huw; Bondareff, Joan; Vethaak, Dick; Deidun, Alan; Sobral, Paula; Topouzelis, Konstantinos; Vlahos, Penny; Lana, Fernanda; Hassellov, Martin; Gerigny, Olivia; Arsonina, Bera; Ambulkar, Archis; Azzaro, Maurizio; Bebianno, Maria João.
Whilst both plastic production and inputs at sea have increased since the 1950s, several modelling studies predict a further increase in the coming years in these respective quantities. We compiled scientific literature on trends in marine litter, consisting largely of plastic and microplastics in the ocean, understanding that monitoring programs or assessments for these aspects are varied, frequently focusing on limited components of the marine environment in different locations, and covering a wide spectrum of marine litter types, with limited standardization. Here we discuss how trends in the amounts of litter in the marine environment can be compared with the information provided by models. Increasing amounts of plastic are found in some regions,...

Lessons learned from an intercalibration exercise on the quantification and characterisation of microplastic particles in sediment and water samples
Provedor de dados: 5
Autores: Cadiou, Jean-francois; Gerigny, Olivia; Koren, Š.; Zeri, C.; Kaberi, H.; Alomar, C.; Panti, C.; Fossi, M.c.; Adamopoulou, A.; Digka, N.; Deudero, S.; Concato, M.; Carbonell, A.; Baini, M.; Galli, M.; Galgani, Francois.
An intercalibration exercise on the characterisation of microplastics in marine sediment and water samples was carried out among five laboratories involved in the implementation of the Marine Strategy Framework Directive (MSFD) in their country. The samples were prepared by mixing cleaned natural sediment and sea water with microplastics sets made of particles of various polymers, shapes and colours. Overall, the errors on total counts were under 25% in absolute value. The risk of non-detection and loss of particles is greater than the risk of contamination during sample analysis. Significant differences are observed among particle types. It appears difficult to obtain reliable and comparable data on the colour of microplastics. A comparison of the errors...

Small-scale variability of the current in the Strait of Bonifacio
Provedor de dados: 5
Autores: Gerigny, Olivia; Coudray, Sylvain; Lapucci, Chiara; Tomasino, Corinne; Bisgambiglia, Paul-antoine; Galgani, Francois.
Current dynamics in the Strait of Bonifacio (south Corsica) were investigated at a small scale during the STELLAMARE1 multidisciplinary cruise in summer 2012, using in situ measurements and modeling data. The Strait of Bonifacio is a particularly sensitive marine area in which specific conservation measures have been taken to preserve the natural environment and wild species. Good knowledge of the hydrodynamics in this area is essential to optimize the Marine Protected Area's management rules. Therefore, we used a high-resolution model (400 m) based on the MARS3D code to investigate the main flux exchanges and to formulate certain hypotheses about the formation of possible eddy structures. The aim of the present paper is first to synthetize the results...

Seafloor litter from the continental shelf and canyons in French Mediterranean Water: Distribution, typologies and trends
Provedor de dados: 5
Autores: Gerigny, Olivia; Brun, Melanie; Fabri, Marie-claire; Tomasino, Corinne; Le Moigne, Morgan; Jadaud, Angelique; Galgani, Francois.
Seafloor litter has been studied both on the continental shelves (by trawling during 24 years) and in canyons (by ROV) of the French Mediterranean sea Water (FMW). On the continental shelf, mean densities range from 49.63 to 289.01 items/km2. The most abundant categories were plastic, glass/ceramics, metals and textiles. Trend analysis shows a significant increase in plastic quantities during the study period. Plastics accumulate at all depths, with heavier items being found in deeper areas, while the continental slope-break appears as a clean area. The spatial distribution of litter revealed the influence of geomorphologic factors, anthropic activities, shipping route, river inputs. All the canyons are affected by debris but coastal canyons (Ligurian Sea...

Monitoring and Assessment guidelines for Marine Litter in Mediterranean MPAs
Provedor de dados: 5
Autores: Galgani, Francois; Deidun, Alan; Liubartseva, Svitlana; Gauci, Adam; Doronzo, Bartholomeo; Brandini, Carlo; Gerigny, Olivia.
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 based on 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...
