Mixing and Transformation in a Deep Western Boundary Current: A Case Study

Carl P. Spingys et al.

Summary: The study focused on water-mass transformation and underlying processes in the Orkney Deep in the Southern Ocean, showing that vigorous turbulent mixing drives density space transport focusing and lightening/densification of layers within a deep western boundary current. Turbulence operates with high efficiency within the current, characterized by a dissipation ratio exceeding the common value, primarily driven by strong turbulence acting on a transition from weakly stratified bottom boundary layer to well-stratified off-boundary waters.

Goldilocks mixing in oceanic shear-induced turbulent overturns

A. Mashayek et al.

Summary: A new parameterization based on the ratio of Thorpe and Ozmidov scales for the irreversible turbulent flux coefficient is presented, covering all key phases of a shear-induced stratified turbulence life cycle. The importance of the intermediate 'Goldilocks' phase, characterized by efficient energy transfer from background shear to turbulent mixing, is highlighted. The parameterization is supported by oceanographic datasets, emphasizing the significance of capturing turbulent flux associated with rare energetic overturns and the representation of young turbulent patches in connecting small scale physics to larger scale mixing applications.

The influence of front strength on the development and equilibration of symmetric instability. Part 1. Growth and saturation

A. F. Wienkers et al.

Summary: Submesoscale fronts in the upper ocean, characterized by large horizontal buoyancy gradients and Rossby numbers, are associated with significant vertical transport and high biological activity. These fronts are susceptible to symmetric instability (SI), a form of stratified inertial instability that occurs when potential vorticity is opposite in sign to the Coriolis parameter. The strength and energetics of SI in these fronts depend strongly on factors such as the horizontal buoyancy gradient and vertical stratification.
