Microstructure observations over the Black Sea shelf and slope north of the Bosphorus reveal a very small turbulent diapycnal diffusivity, K(rho) approximate to 10(-6) m(2) s(-1) in the Cold Intermediate Water during late summer, when winds are at their seasonal minimum. Recent modeling by Oguz et al. [1998] shows that only with such low diffusivity can the observed separation between dissolved oxygen, O(2), and hydrogen sulfide, H(2)S, be maintained. The measurements also provide a reference for mixing over continental shelves where tides are negligible and when winds are light.
