对黑海陆架和博斯普鲁斯海峡以北斜坡的微观结构观测表明，夏末冷中层水中的湍流二重扩散率非常小，Kρ ≈ 10−6 m² s−1，此时风处于季节性最小值。 Oğuz 等人最近的建模。 [1998]表明，只有具有如此低的扩散率，才能维持观察到的溶解氧（O2）和硫化氢（H2S）之间的分离。这些测量结果还为潮汐可以忽略不计且风力微弱的大陆架上的混合提供了参考。
Microstructure observations over the Black Sea shelf and slope north of the Bosphorus reveal a very small turbulent diapycnal diffusivity, Kρ ≈ 10−6 m² s−1 in the Cold Intermediate Water during late summer, when winds are at their seasonal minimum. Recent modeling by Oğuz et al. [1998] shows that only with such low diffusivity can the observed separation between dissolved oxygen, O2 and hydrogen sulfide, H2S, be maintained. The measurements also provide a reference for mixing over continental shelves where tides are negligible and when winds are light.
