The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...
