Abstract : To develop quantitative means (hydrodynamic diagrams) to determine the hydrodynamic state of microstructure patches in stratified and rotating flows such as the ocean; that is, whether the patches represent active turbulence, active-fossil turbulence, or completely fossil turbulence. A precise definition of turbulence has been proposed that shows the direction of the turbulence cascade usually assumed is incorrect. The Reynolds rules of averaging postulates of 1894 used in dissipation flux balances such as the Osborn and Cox (1972) equation K=DC are re-examined by a control volume averaging technique in Gibson (JGR Nov.1991), that reveals the need for averaging over very large data sets, with length scales larger than the largest turbulence scales in either the horizontal or vertical.
