A theory for the abyssal stratification and circulation is derived from the principle of maximal production of information entropy used in non-equilibrium statistical dynamics. For an abyssal ocean of simple geometry and simple, though plausible, parameterization of the vertical diffusivity, stratification profiles together with their associated circulation are obtained. These profiles are characterized by an abyssal thermocline thickness scaling as √ κvH/ws0, where ws0 is the upwelling velocity at the top of an abyssal ocean of depth H, and κv is its vertical diffusivity. Remarkably, the associated circulation is barotropic and coincides with the classical theory of the abyssal circulation by Stommel and Arons.
