Heat transport in the polar oceans has a central control on sea-ice cover and global climate. Motivated by the need to better understand this heat transport, I explore a type of small-scale ocean mixing - double-diffusive convection. Double-diffusive convection gives rise to layered structures in the polar oceans: double-diffusive staircases and sometimes thermohaline intrusions. Recently I have been focusing on the question of whether double-diffusive mixing regulates the thickness of sea ice in the Ross Gyre, Southern Ocean.
