Mesoscale Eddies Boost Ocean Ventilation, Impacting Global Climate

Mesoscale eddies significantly enhance the ventilation of Antarctic Intermediate Water (AAIW) in the South Atlantic, a crucial process influencing global ocean circulation and climate. This research highlights the eddies' role in carbon and heat uptake, with implications for ocean models. Their impact is particularly notable in the Indian Ocean sector.
