  • March 5, 2015: A microscale view of mixing and overturning across the Antarctic Circumpolar Current
    Alberto Naveira-Garabato (U of Southampton, UK)
    The relative roles of isopycnal stirring by mesoscale eddies and diapycnal stirring by small-scale turbulence in setting the large-scale temperature - salinity relation of the Southern Ocean against the action of the overturning circulation are assessed, by analysing a set of shear and temperature microstructure measurements across Drake Passage in a `triple decomposition' framework. It is shown that a full picture of regional mixing and overturning across the Antarctic Circumpolar Current (ACC) may be constructed from a modest number of microstructure profiles. The rates of isopycnal and diapycnal stirring are found to exhibit distinct, characteristic and abrupt variations: most notably, a one-to-two order of magnitude suppression of isopycnal stirring in the upper kilometre of the ACC frontal jets, and an order-of-magnitude intensification of diapycnal stirring in the sub-pycnocline and deepest layers of the ACC. These variations balance an overturning circulation with meridional flows of O(1 mm / s) across the ACC's mean thermohaline structure. Isopycnal and diapycnal stirring play complementary roles in balancing the overturning, with isopycnal processes dominating in intermediate waters and the Upper Circumpolar Deep Water, and diapycnal processes prevailing in lighter and denser layers. The implications of this balance for our present view of the Southern Ocean circulation will be discussed.
