Diapycnal mixing (across density surfaces) is an important process in the global ocean overturning circulation. Mixing in the interior of most of the ocean, however, is thought to have a magnitude just one-tenth of that required to close the global circulation by the downward mixing of less dense waters. Some of this deficit is made up by intense near-bottom mixing occurring in restricted ‘hot-spots’ associated with rough ocean-floor topography, but it is not clear whether the waters at mid… 
Topographic enhancement of vertical turbulent mixing in the Southern Ocean
TLDR
Using a high-resolution ocean model, it is shown that the fast vertical spreading of tracer occurs when it comes in contact with mixing hotspots over rough topography, and the increased tracer residence time may explain the large vertical fluxes of heat and salt required to close the abyssal circulation.
Multi-timescale control of Southern Ocean diapycnal mixing over Atlantic tracer budgets
Oceanic cross-density (diapycnal) mixing helps sustain the ocean den- sity stratification and its Meridional Overturning Circulation (MOC) and is key to global tracer distributions. The Southern
Diapycnal motion, diffusion, and stretching of tracers in the ocean
Small-scale mixing drives the diabatic upwelling that closes the abyssal ocean overturning circulation. Measurements of in-situ turbulence reveal that mixing is bottom-enhanced over rough topography,
Spatial and seasonal variability of global ocean diapycnal transport inferred from Argo profiles
The global diapycnal transport in the ocean interior is one of the significant branches to return the deep water back toward near-surface. However, the amount of the diapycnal transport and the
Diapycnal mixing in the Southern Ocean diagnosed using the DIMES Tracer and Realistic Velocity Fields
In this work, we use realistic isopycnal velocities with a 3‐D eddy diffusivity to advect and diffuse a tracer in the Antarctic Circumpolar Current, beginning in the Southeast Pacific and progressing
Transformation of Deep Water Masses Along Lagrangian Upwelling Pathways in the Southern Ocean: SOUTHERN OCEAN UPWELLING TRANSFORMATION
Upwelling of northern deep waters in the Southern Ocean is fundamentally important for the closure of the global meridional overturning circulation and delivers carbon and nutrient-rich deep waters
Spiraling pathways of global deep waters to the surface of the Southern Ocean
TLDR
The authors present a three dimensional view showing a spiralling southward path, with enhanced upwelling by eddy-transport at topographic hotspots, associated with vigorous mesoscale eddy activity.
Observations of a diapycnal shortcut to adiabatic upwelling of Antarctic Circumpolar Deep Water
In the Southern Ocean, small‐scale turbulence causes diapycnal mixing which influences important water mass transformations, in turn impacting large‐scale ocean transports such as the Meridional
Modification of the deep salinity-maximum in the Southern Ocean by circulation in the Antarctic Circumpolar Current and the Weddell Gyre
The evolution of the deep salinity-maximum associated with the Lower Circumpolar Deep Water (LCDW) is assessed using a set of 37 hydrographic sections collected over a 20-year period in the Southern
Tracking the spread of a passive tracer through Southern Ocean water masses
Abstract. A dynamically passive inert tracer was released in the interior South Pacific Ocean at latitudes of the Antarctic Circumpolar Current. Observational cross sections of the tracer were taken

Evidence for enhanced mixing over rough topography in the abyssal ocean
TLDR
This amount of mixing, probably driven by breaking internal waves that are generated by tidal currents flowing over the rough bathymetry, may be large enough to close the buoyancy budget for the Brazil basin and suggests a mechanism for closing the global overturning circulation.

Spatial Variability of Turbulent Mixing in the Abyssal Ocean
TLDR
Ocean microstructure data show that turbulent mixing in the deep Brazil Basin of the South Atlantic Ocean is weak at all depths above smooth abyssal plains and the South American Continental Rise, which implies that abyssal circulations have complex spatial structures that are linked to the underlying bathymetry.
