When the near surface layer is subject to wind forcing a layer of enhanced turbulence is found within the mixed layer, well above the pycnocline. The layer of enhanced turbulence we define as the mixing depth. This mixing depth was observed in three different areas (Atlantic Ocean, Baltic Sea and Lake Maggiore) applying different methods and microstructure measuring profilers. From these measurements a well pronounced correlation between the mixing depth H(w) and the windspeed W was found and it was possible to derive a parameterization in the form: H(w) = 0.057(*)W(2.5). This parameterization is valid for windspeeds between 1 metres per second up to about 15 metres per second.
