Multi-decadal trends in the advection and mixing of natural carbon in the Southern Ocean
Multi-decadal trends in the advection, mixing, and air-sea flux of natural carbon dioxide (CO₂) in the Southern Ocean are investigated using output from a hindcast simulation of a non-eddy-resolving ocean model. Particular emphasis is placed on the model's improved eddy-induced advection parame...
