| Description | Revised diagnosis of the distribution of isopycnal mixing in the Southern Ocean. Determination of the roles of eddy kinetic energy and mixing suppression by jets in setting mixing rates. Resolution of the apparent paradox of weak mixing in regions of high eddy kinetic energy seen in zonal mean sections of the Antarctic Circumpolar Current. Assessment of the temporal variability of isopycnal mixing in the Southern Ocean. Demonstration (from the spread of a deliberate tracer) that mid-depth diapycnal mixing is greatly enhanced over rough topography in the Southern Ocean. First systematic assessment of finescale parameterizations of turbulent mixing with microstructure measurements. |
