Although, numerous studies have assessed the extent of this pollution in various regions of the world, our knowledge about the situation on the African continent and its oceanic islands is still limited. To address this gap, repeated beach debris surveys were conducted on six beaches on the island of São Vicente, Cabo Verde, over the course of six weeks from May to July 2023, with surveys conducted every four days. This was done to compare debris accumulation rates as well as debris composition between beaches that differ in their orientation, exposure and level of human use. Furthermore, we assessed the density of mesoplastic particles (1–10 mm) and correlated it with the amount of macroplastic debris (>10 mm) encountered. A backward ocean current simulation with PARCELS allowed to identify possible origins of the plastic items from ocean-sources. We observed an average macrodebris (> 10 mm) accumulation rate of 0.05 ± 0.06 items/m2/d (0.2 ± 0.4 g/m2/d), while the rates varied strongly between beaches. The number of macroplastic items was positively correlated with the abundance of mesoplastic particles (r2 = 0.982, p = 0.0004), for which we found an average density of 121.7 ± 339.1 mesoplastic particles/m2. The particle tracking by backward ocean current simulations demonstrated the existence of a transport pathway from the northwest coast of Africa towards the Cabo Verde archipelago. This suggests the northwest African shore as a potential source of the anthropogenic debris found on São Vicente.', }, + { + title: + 'Oceanward surface transport from the NW African upwelling zone by coastal jet detachment and filaments', + published_info: 'Frontiers in Marine Science, 13', + authors: + 'Rader, L, B Aguiar-González, TD Price, D Vega-Moreno, E Fraile-Nuez, F Machín (2026)', + doi: 'https://doi.org/10.3389/fmars.2026.1757436', + abstract: + 'The oceanward surface transport of particles, including marine litter, from the northwestern African upwelling zone is influenced by multiple interacting physical processes. This study applies the OceanParcels Lagrangian framework to investigate the mechanisms that may contribute to oceanward surface transport in this region, motivated by the hypothesis that the northwestern African upwelling system could represent a potential source of marine litter in the vicinity of the Canary Islands. The simulations suggest that the coastal jet stream and its detachment, upwelling filaments, and Stokes drift play key roles in shaping particle trajectories. In particular, coastal jet detachment appears to organize surface transport into narrow, oceanward-oriented particle corridors, while upwelling filaments may provide additional offshore export pathways. Stokes drift introduces a predominantly southward deflection that can reduce or modulate oceanward advection and enhance alongshore transport. These results provide a process-based, model-derived first assessment of previously understudied oceanward transport corridors in the NW African upwelling system. They are consistent with the hypothesis that this region may contribute to surface tracer transport toward the Canary Islands. However, caution is required when extrapolating these findings to marine debris, as windage is not included and may significantly alter transport pathways. Continued investigation, including observational validation and improved surface forcing representations, will help further constrain the mechanisms shaping particle transport in the NW African upwelling system.', + }, ]
