The influence of floating marine debris (FMD) on coastal and communities ecosystems is undeniable, attention increasingly focused ecologically biologically important areas. To protect life valuable resources from FMD pollution, identifying accumulation zones recognized as a priority. One the ocean processes found governing distribution water convergence (frontal zones). These fronts are driven by various oceanographical factors. date, transport in relation to areas poorly understood. address this knowledge gap, we reviewed types well along frontal defined region between coastline shelf break. Frontogenesis (physical related formation) were alongside studies identify physical factors that drive pathways these This review will contribute our understanding hotspots within gaps for further research developing proxy hotspot identification

The water quality in port domains is highly dependent on the capacity for renewal and mixing with external water. This study uses Lagrangian modelling to investigate time Barcelona, Tarragona, Gijón harbours (Spain), which represent semi-enclosed micro-tidal meso-tidal environments. For this purpose, different particle-tracking simulations have been carried out each of ports trends circulation both surface layer at bottom. results indicate that microtidal Mediterranean ports, longer bottom (32 days Barcelona 61 Tarragona). Conversely, mesotidal Gijón, located Cantabrian coast, opposite pattern observed, higher times (14 days). While from exhibit magnitudes comparable situ measurements previous studies, it remains essential evaluate specific characteristics method compare these findings other similar works.

The threat of anthropogenic marine litter, particularly plastic pollution, to ecosystems and human health, has spurred mitigation initiatives global scientific research. Following the Marine Strategy Framework Directive guidelines, this study evaluated litter distribution, cleanliness, pollution indices along Bulgarian Black Sea beaches in 2023. survey integrates visual assessment, manual sampling, drone mapping, distributing coastline encompass a broader range, totaling 45, including 28 remote/natural, 10 semi-urban, 7 urban beaches. Results indicate 48% decrease distribution on from 1462 ± 147 items/100 m 2021 753 97 2023, with Artificial polymer materials/plastic materials constituting 88.62% total amount. A comprehensive macro assessment was carried out using PAI for first time. In average cleanliness status classified as “ moderate ” (CCI: 7.61 1.00), clean northern central contrasting dirty southern Urbanized were assessed highest level (PAI AV,23 : 5.51; CCI 18.16). long term, maintain values AV,18-23 8.81 0.89, 2.35 0.32, persisting throughout period, necessitating ongoing monitoring intervention strategies. Despite identifying significant number beaches, none meet EU threshold value 20 m. This highlights urgent need effective interventions combat accumulation or semi-urban emphasizing multi-stakeholder collaboration sustainable solutions coastal ecosystem preservation.
