Turbulent mixing in the ocean interior is believed to play an important role in shaping ocean circulation and tracer distributions and, in so doing, in influencing global climate. However, the extent of this role, and its dependency on the physics of mixing, remain little explored and poorly quantified. I will review the observational underpinnings of ocean mixing and show that, on annual to millennial time scales, mixing exerts a leading-order control on the rate, structure and internal variability of the ocean’s meridional overturning circulation, and on the oceanic budgets of climatically key tracers such as heat and carbon.
