Double diffusion is a type of mixing process that may arise in the oceans where temperature and salinity determine density gradients. Active double-diffusive convection manifests as stacked well-mixed water layers, forming a staircase structure. The Arctic Ocean exhibits a prominent double-diffusive staircase which indicates how deep-ocean heat is mixed upward toward the sea ice. In this talk, I will discuss a one-dimensional mathematical model to examine how this double-diffusive heat transport may be influenced by mechanical mixing, or turbulence, such as that driven by winds and waves. I will also discuss how a 15-year observational record of the Arctic’s thermocline displays a shift in double-diffusive staircase structure under Arctic warming.
