SUMMARY:Open questions in turbulent stratified mixing: Do we even know wha
 t we do not know? - C. P.  Caulfield\, BPI and DAMTP

DESCRIPTION:Understanding how turbulence leads to the enhanced irreversibl
 e transport of heat and other scalars (such as salt and pollutants) in den
 sity-stratified fluids is a fundamental and central problem in geophysical
  and environmental fluid dynamics. There is a wide range of highly importa
 nt applications\, not least the description and parameterization of diapyc
 nal transport in the world's oceans\, a key area of uncertainty in climate
  modelling. Recently\, due not least to the proliferation of data obtained
  through direct observation\, numerical simulation and laboratory experime
 ntation\, there has been an explosion in research activity directed at imp
 roving community understanding\, modelling and parameterization of the sub
 tle interplay between energy conversion pathways\, turbulence\, and irreve
 rsible mixing in density-stratified fluids. However\, as I will discuss in
  this talk\, there are still leading order open questions and areas of pro
 found uncertainty concerning turbulent stratified mixing. Therefore\, I wi
 ll present a personal perspective on some priorities for further research 
 into this hugely complex\, important and fascinating fluid dynamical chall
 enge.
