Poleward undercurrent eddies (Puddies) transport the source water mass with low oxygen hundreds of kilometers away from the coast. A simulation based on a physical–biogeochemical model was used to characterize the average biogeochemical conditions inside the Puddies during their lifetime while modifying the conditions in the open sea. Our findings show that the biological activity extends the low-oxygen core conditions counteracted by advection processes that tend to ventilate the core.
