Short summary
This study aims to analyse the changes of the vertical structure of the ocean during upwelling and the role of climate patterns in the Canary Current (25–35°N) over a period of 25 years (1993–2017). Ocean mixing is enhanced during upwelling events and extends deeper (shallower) in the winters of positive (negative) North Atlantic Oscillation. It is enhanced during coupled, opposite phases of the East Atlantic pattern, suggesting stronger upwelling activity independent of climate patterns.
