Two sets of turbulence decaying experiments have been performed, with the aim of focusing in the middle of a strongly stratified density interface. The experiments have been done under two different external conditions: a) stirring (non-rotating) decaying 2D turbulence experiments and b) rotating decaying 2D turbulence experiments. Non-rotating experiments were performed in a 1×1m tank, while the rotating experiments were performed in a rectangular tank of 4×2m; this rectangular tank was placed in the middle of the Coriolis rotating platform from the Trondheim Marine Systems Research Infrastructure supported by the European Community TMR Project. The set of stirred experiments is a compilation of five series of mixing experiments, dependent on the initial interfacial Richardson number. The total time of mixing was between 53 and 72 minutes. The density of the brine used in the experiment after was between 1027 and 1037 kgm−3. The boundary conditions for all the rotating experiment are related to initial Reynolds Rer, Rossby Ro, Ekman Ek and Richardson gradient Rig numbers, the results are summarized and presented in a 3D parameter map using potential relationships.
