This study employs a high-resolution ROMS hydrodynamic model coupled with a Lagrangian particle-tracking framework to quantitatively investigate the cross-shelf transport of surface particles released during the summer monsoon of June 2020. Simulation results reveal distinct spatial heterogeneity in transport patterns. While the inner shelf is largely constrained by alongshore currents, the widened topography at the eastern shelf acts as a critical offshore "leakage" pathway. In the middle and outer shelves, cross-shelf exchanges are highly active, predominantly driven by entrainment from a western mesoscale cyclonic eddy, forming filamentary structures that transport water beyond the 1000-m isobath. While intensified southwesterly winds are expected to enhance offshore Ekman transport, our results show that they simultaneously suppress eddy-mediated export by modulating the alongshore pressure gradient. Momentum balance analysis reveals the underlying mechanism: strong alongshore winds induce water accumulation on the northeastern shelf, elevating sea level and generating a southwestward (downstream) pressure gradient force. This downstream force disrupts the quasi-geostrophic balance required for particle capture by the western eddy, leading to a net reduction in cross-shelf particle export despite the enhanced wind forcing. Consequently, particles are transported rapidly alongshore under strong winds, whereas weaker winds favor northeastward (upstream) pressure gradients that enhance eddy capture efficiency. This study elucidates the complex interplay between monsoon intensity, shelf topography, and mesoscale eddies, providing critical insights into pollutant residence times and biogeochemical fluxes in marginal seas.', }, + { + title: + 'Meso- to Submesoscale Variability of Particulate Carbon Export Captured by a Glider-Camera System in the Northeast Atlantic During the APERO Campaign', + published_info: + 'Journal of Geophysical Research: Oceans, 131, e2025JC023403', + authors: + 'Chevillon, E, A Bosse, B Zakardjian, A Accardo, L Guidi, N Bhairy, J-L Fuda, M Picheral, C Luneau, P Dasi, L Memery (2026)', + doi: 'https://doi.org/10.1029/2025JC023403', + abstract: + 'Between 9 June and 6 July 2023 a SeaExplorer glider equipped with an Underwater Vision Profiler (UVP6), surveyed frontal structures between a cyclonic and two anticyclonic eddies in the Northeast Atlantic as part of the APERO cruise (Assessing marine biogenic matter Production, Export and Remineralization: from the surface to the dark Ocean) that was designed to quantify the spatial and temporal variability of the biological carbon pump (BCP) from the surface to the mesopelagic zone. Combined high-resolution physical, biogeochemical, and imaging observations resolved particulate organic carbon (POC) distributions and fluxes across (sub)mesoscale features. Particle concentrations, POC stocks, and fluxes showed pronounced spatial heterogeneity, with sharp gradients at frontal interfaces and enhanced variability in larger particle size classes. Estimated POC fluxes varied by up to an order of magnitude over distances <10 km at the surface, with variations of up to a factor 2–3 at 1,000 m. Lagrangian backward trajectories from altimetry revealed that these signals detectable at submesoscale resulted from convergence of outer water masses in frontal zones, whereas vertical processes were primarily responsible for biogeochemical variability within eddy cores. Secondarily it is shown that optical backscattering underestimated and poorly resolved deep variability of large-particle POC when compared with UVP-derived ones, but it is proposed that combining both sensors may improve total POC estimates. These results demonstrate that glider-UVP6 systems provide a powerful approach to capture fine-scale BCP variability and constrain vertical carbon export estimates.', + }, ]
