ABSTRACT Structures similar to the oceanic ‘salt fingers’ that form when warmer more saline water overlies cooler fresher water1 have recently been observed2, in concentrated solutions of

polymers in conditions where fingers would not form according to the usual criteria. We here extend previous theories to derive the conditions under which double-diffusive convection can

occur in a solution of a pair of solutes with a large coupled diffusion (or cross-diffusion) effect, that is, where a flux of one property is driven by a spatial gradient of another. Access
