Whitehead with Thermohaline Convection - Laboratory experiments using a large reservoir and small chamber, with flow determined by the difference in salinity and temperature, support the theory of H. Stommel on multiple states of thermohaline convection. J.A. Whitehead, Multiple states in doubly driven flow. Physica D 97 (1996), 311–321. J.A.
