class

Mixing and dispersion in the ocean is of fundamental importance in many oceanographic problems, including climate modeling, paleo and present-day circulation studies, pollutant dispersion, biogeography, etc. The main goal of this course is to provide in-depth understanding (rather than mathematical derivations) of the causes and consequences of mixing in the ocean, and of the properties of dispersion. After introducing the concepts of diffusion and turbulence, instruments and techniques for quantifying mixing and dispersion in the ocean are reviewed and compared. Next, the instabilities and processes giving rise to turbulence in the ocean are discussed. The course concludes with a series of lectures on mixing and dispersion in specific oceanographic settings, including boundary layers, shallow seas, continental shelves, sea straits, seamounts, and mid-ocean ridge flanks.
