Abstract
• Cyclonic eddies pump DIC and nitrate upwards leading to less oceanic carbon uptake, and anticyclonic eddies have the opposite impact • Cyclonic eddies pump low-oxygen water upwards (anticyclones opposite) and eddy trapping leads to opposite anomalies at depth • The net anomalous eddy-induced Southern Ocean carbon uptake is ∼0.02±0.02 Pg C yr −1 , with larger signals seasonally and regionally30 Aug 2024Submitted to ESS Open Archive 30 Aug 2024Published in ESS Open Archive
