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.',

'Antarctic Intermediate Water (AAIW) contributes to the northward flow required to compensate the export of North Atlantic Deep Water from the North Atlantic Ocean to other basins and therefore plays a crucial role in the Atlantic Meridional Overturning Circulation. Based on observations and outputs from an ocean reanalysis we present evidence of a narrow band of relatively fresh (≤34.20) and oxygen rich (>260 μmol.kg−1) newly formed AAIW which extends northwards, past the Brazil-Malvinas Confluence (BMC) up to 34.5°S. We investigated the probability of occurrence of this phenomenon, the possible driving mechanisms, and its seasonal and inter-annual variability. Our results indicate that this flow is weak and intermittent, confined to the upper continental slope near the 1000 m isobath. The mean travel time between 38 and 39°S, south of the BMC, and 34.5°S is 205–217 days; occasionally, during the development of intense pulses, the travel time reduces to less than 60 days. The mean particle velocity during pulses is 12.60 cm.s−1. A weakening or reversal of the southward flowing Brazil Current (BC) is observed prior to strong pulses; this circulation pattern could facilitate the northward pathway of relatively fresh AAIW. The BC intensifies during February-March and weakens during August-September; thus, the northward AAIW pulses are also observed more frequently in September. The northward extension of the relatively fresh variety of AAIW is also favoured by cyclonic circulations trapped against the slope onshore from the core of the BC.',
