abstract:
'This study presents direct in situ observational evidence of a cyclonic circulation cell east of Cape Santa María (CSM), in the northern Gulf of Cádiz (GoC). Three Lagrangian drifters deployed in October 2022 revealed a coherent cyclonic circulation cell with a characteristic diameter of approximately 40-45 km, consistently estimated from drifter trajectories and relative vorticity. Their trajectories showed alternating eastward and westward flows, modulated by wind variability, bathymetry, and mesoscale dynamics. Satellite observations showed a cooler, chlorophyll-a enriched core, consistent with upwelling and retention of enriched surface water masses within the circulation cell. High-resolution WRF atmospheric simulations indicated alternating easterly and westerly wind regimes that were associated with reversals in coastal circulation. Westerly winds between 18th and 24th October produced positive Ekman pumping east of CSM, creating conditions favourable to the intensification of cyclonic circulation. The IBI ocean model reproduced the main structure of the circulation cell structure, including flow accelerations near the shelf edge, and indicated upward vertical motions within the cyclonic circulation cell. A Lagrangian particle experiment suggested that the cyclonic cell favours both retention and offshore export of surface waters, with residence times of up to approximately 16 days. Overall, this study highlights the role of interactions between atmospheric forcing, bathymetry, and mesoscale dynamics in controlling small-scale surface circulation in the GoC, and underscores the value of integrating drifter observations, satellite data, and numerical models to characterize coastal dynamics.',

'Antarctic krill are central to the Southern Ocean ecosystem and support a commercial fishery. Late larval stages of Antarctic krill depend on sea ice for food and shelter during winter. As climate change alters sea ice habitats and polar ecosystems, understanding krill transport and retention is essential for ecosystem-based fishery management. These late-stage larvae have been observed to perform reverse diel vertical migration (DVM), moving from beneath the sea ice during the day to the upper water column at night. Variability in ocean currents and sea ice drift, together with behaviours such as DVM, can strongly influence krill transport and retention. To investigate the impact of this behaviour, we conducted Lagrangian particle tracking experiments using 32 years of daily sea ice and ocean velocities from a 0.1° global ocean-sea ice model (ACCESS-OM2-01). Virtual particles were released in the south-west Atlantic sector of the Southern Ocean and tracked over winter (April-October), a key period prior to spring recruitment. To assess sensitivity to DVM, we applied five scenarios in which particles spent different proportions of each day influenced by ocean currents and sea ice drift under sea ice. Transport driven solely by ocean velocities resulted in the highest proportion of particles on the Antarctic Peninsula shelf by winters end, with low interannual variability (55.5% ± 7% of released particles). Increasing exposure to sea ice drift reduced shelf retention and increased variability (33.6% ± 10.9%). Our results show that including sea ice interactions enhances overwinter connectivity from the Antarctic Peninsula to South Georgia and between management areas, highlighting sea ice-driven northward transport of young krill. As krill depend on declining sea ice habitats, connectivity across the Antarctic Peninsula and Scotia Sea may shift in the future. Understanding interannual transport variability between fishing regions improves stock assessment and supports sustainable management.',
