Scientific paper

Microstructure measurements were conducted in one of the Kuril Straits in the summer of 2007. Over the course of 1 day of repeated observations across the Pacific side of the steep sill of the Urup Strait, extremely strong mixing was observed during periods of Pacific-ward (down-sill) flows and during the transition from Pacific-ward to Okhotsk-ward (up-sill) flows, with a turbulent energy dissipation rate $\varepsilon$ of 10-6 to 10-5 W kg-1 and vertical diffusivity of 10-1 to 5 × 10-1 m2 s-1. During the period of strong mixing, we observed homogeneous layers with a thickness of 300-600 m and potential density of 26.6-26.7 σ$\theta$, occupying the entire water column in one case. High values of $\varepsilon$ within this layer indicate the injection of diapycnal flows from the upper and lower layers, possibly contributing to southward intrusion of intermediate water into the subtropical gyre.
