abstract:
'Introduction: The Mediterranean is a major hotspot for floating marine macro-litter (FMML) accumulation, yet spatially explicit, observation-grounded predictions of its transport and coastal deposition remain scarce. We present a data-driven stochastic Lagrangian framework that uses monthly gridded FMML observations from systematic shipboard surveys as simulation initial conditions complementing existing source-based modelling approaches.Methods: Observations were collected from August 2023 to December 2024 within the LIFE Conceptu Maris Project using ferries as monitoring platforms under a standardised protocol. A total of 158 surveys detected 4,801 FMML items across approximately 6,200 km² of surveyed sea surface, of which more than 62% were artificial polymers. Observed monthly FMML item counts at 5 × 5 km resolution initialised ensemble Lagrangian simulations (18 members per target month; 17.2–32.5 million virtual particles per seeding window, 5,000 particles per observed item) using Parcels, forced by Copernicus Marine Service Mediterranean reanalysis currents and ERA5 wind fields with a 1% windage coefficient and a 2D random-walk turbulent diffusion scheme. Monthly frequency-of-occurrence maps were computed at the sea surface and on coastlines.Results: The Southern Tyrrhenian and Northern Ligurian seas, including the Pelagos Sanctuary, exhibited in 2024 near-persistent high sea surface FMML occurrence, peaking in late summer–autumn and reaching a seasonal minimum in winter–early spring. The Balearic Sea showed elevated occurrence from late spring through summer (May–September), declining through autumn. The Adriatic displayed intense sub-basin-scale spreading from January to June and again in December, with summer leakage into the Northern Ionian Sea. Coastal deposition frequencies were highest on Corsica, western Sardinia and northern Tunisia, then the south-eastern Tyrrhenian and Ligurian–Tuscan margins, with Valencia–Barcelona largely confined to summer. Integration with loggerhead turtle nesting records illustrates how coastal frequency-of-occurrence maps can support conservation applications.Discussion: A web-based Particle Analysis Dashboard translates these outputs into an interactive tool with Marine Protected and Conserved Area overlays for scientists and decision-makers. The framework provides a scalable, observation-anchored foundation for MSFD Descriptor 10 monitoring, transferable to other semi-enclosed sea basins. Priority future work includes complementary validation against independent beach-litter monitoring data, integration of land-based source inventories, and linkage with species distribution models.',

abstract:
'The Sea of Marmara is undergoing a severe marine pollution crisis driven by chronic nutrient enrichment and recurrent mucilage outbreaks. The physical mechanisms controlling transport, accumulation and persistence of pollutants and organic matter remain insufficiently resolved. Here, we quantify how three-dimensional (3D) circulation regulates dispersal and retention in this strongly stratified, semi-enclosed basin. A high-resolution Lagrangian particle-tracking framework forced by the Coastal and Regional Ocean COmmunity model (CROCO) resolves transport pathways and transit times, with particles as proxies for nutrients and suspended organic matter. Comparing ensembles of two-dimensional (2D) and 3D simulations shows that vertical processes, including shear dispersion and episodic subduction, substantially modify particle pathways and delay horizontal transport. In stratified sub-basins, 3D dynamics extend transit times by up to 100 days relative to 2D estimates, so neglecting vertical exchange systematically underestimates how long material is retained. A persistent retention hotspot emerges in the southwestern basin, where mean transit times exceed 250 days. Such conditions favour the prolonged accumulation of suspended organic material, although mucilage formation additionally involves biological and biogeochemical processes that passive particles do not represent. Lagrangian probability density functions show that dispersal converges on persistent retention areas that recur across release years and release regions, while the rate of accumulation varies between years. These results establish a mechanistic link between 3D circulation and the spatial organization of pollution retention, with implications for monitoring design and mitigation in the Sea of Marmara and analogous stratified semi-enclosed seas.',
