The underlying mechanisms controlling the intensity and timing of these blooms have been proposed to be dominated by vertical transport and mixing processes that are enhanced at fine-scale frontal and filamental circulations, commonly known as submesoscale currents. Here we show that the winter blooms characteristic of the ultra-oligotrophic waters of the Eastern Mediterranean Sea, which manifest as a seasonal increase in satellite-derived levels of surface chlorophyll, are intensified by enhanced horizontal stirring induced by the submesoscale currents. Using ocean color remote sensing data and high-resolution numerical simulations, we demonstrate that the intensification of submesoscale currents in winter efficiently connect the coastal waters and the ultra-oligotrophic open-sea waters, thereby enriching the latter with chlorophyll-rich waters. A climatological chlorophyll time series comparison between two different regions equidistant to the Nile River Delta indicates that this submesoscale horizontal stirring mechanism accounts for the ∼ 24.8 % larger wintertime increase in surface chlorophyll observed downstream of the Nile Delta. These results shed new light on the processes governing phytoplankton bloom intensity and emphasize the important role of submesoscale horizontal stirring in modulating the marine ecosystem.', }, + { + title: + 'On the Role of Western Boundary Currents to Fertilize Adjacent Continental Shelves at Interannual Scales: A Case Study in the Southwestern Atlantic', + published_info: 'Geophysical Research Letters, 53, e2025GL120186', + authors: 'Ferronato, C, M Saraceno, VA Guinder (2026)', + doi: 'https://doi.org/10.1029/2025GL120186', + abstract: + 'Exchanges between continental shelves and open ocean basins regulate the transport of heat, salt, and nutrients. In the Southwestern Atlantic, the western boundary current known as the Malvinas Current (MC) fertilizes the outer shelf through recurrent slope-water intrusions. Here we analyze the 2003–2024 interannual variability of satellite chlorophyll-a around 41°S, where the inflection of the 100-m isobath promotes these incursions. The first Empirical Orthogonal Function mode explains 43% of the variance and exhibits a spatial pattern consistent with the MC intrusion zone. Backward Lagrangian simulations reveal that low-chlorophyll periods correspond to waters advected by the onshore MC jet, whereas high-chlorophyll years are linked to offshore-origin parcels likely richer in nutrients. Sea-level anomaly composites indicate that mesoscale eddies near 40°S can block or deflect the MC, favoring intrusions onto the shelf. These results provide new quantitative evidence that variability in boundary-current pathways strongly modulates interannual changes in chlorophyll-a over continental shelves.', + }, ]
