Ocean mixing is a physical oceanographic phenomenon encompassing the turbulent and wave-driven processes that irreversibly redistribute heat, salt, momentum, and biogeochemical tracers within the ocean interior and boundary layers. It is mediated by shear instability, double-diffusive convection, internal waves (including internal tides), and boundary-generated turbulence, and is quantified using parameters such as diapycnal and isopycnal diffusivities. Ocean mixing regulates the vertical exchange between the surface and deep ocean, controls stratification and overturning circulation, influences climate-relevant heat and carbon storage, and sets nutrient supply to the euphotic zone, thereby coupling physical dynamics with marine biogeochemistry.
Beneath Antarctica's Ross Ice Shelf lies one of the least measured oceans on Earth—a vast, dark cavity roughly twice the volume of the North Sea.
