Scientific paper

It is shown using detailed yearlong acoustic current observations between 850 and 1350 m that large-scale and small-scale waves in the ocean interior are coupled in a self-regulating fashion. Vertical current shear, a key to vertical mixing, is dominated near the local inertial frequency. Its value follows details of maximum buoyancy frequency `Nmax' in thin layers of different density. Its frequency however, is determined by the minimum Nmin in the near-homogeneous layers between the Nmax-layers. These weakly stratified layers are maintained by overturning of density surfaces due to high-frequency internal waves guided by the shear-layers. Rare vertical current observations show a spectral continuum between [Nmin, Nmax] of low-mode interfacial waves rather than wave-groups propagating through smooth large-scale stratification.
