Turbulent mixing has an important influence on many physical processes in the ocean. For example, the upwelling of water through the stably stratified ocean interior, needed to close the global circulation, is only possible through the enhanced vertical mixing resulting from turbulence. In this talk, I will discuss how idealized turbulence simulations can be used to investigate the fundamental mechanisms driving mixing in the ocean. I will also demonstrate the importance of distinguishing this diffusive mixing from turbulent stirring, and highlight how this connects to the concept of available potential energy.
