DESCRIPTION:Measuring the rate of vertical mixing in the interior of the d
 ensity-stratified ocean is essential to determining the distribution of he
 at\, biologically important nutrients and the fate of pollutants. As demon
 strated by Munk (1966) in his “Abyssal Recipes” paper\, we know the ra
 te of mixing controls the nature of the abyssal circulation and thus ocean
  mixing is dynamically important on both short and long timescales. The hi
 story of making measurements of mixing dates back over 50 years and the pr
 inciple tool has been free-falling turbulent microstructure profilers.  Th
 e interpretation of these measurements remains a subject of debate\, howev
 er\, and the talk will discuss three different methods that have been prop
 osed to interpret microstructure measurements. We will also compare profil
 er measurements with measurements from fixed moorings.  Moorings have the 
 potential of offering long records of mixing over the entire water column 
 and thus one means of increasing the amount of measurements which\, despit
 e 50 years of effort\, still remain relatively scarce.
