Marine Turbulence (Physics MSc)

Building up on the basic material covered in Hydrodynamics, this class provides an introduction to turbulence and mixing from an oceanographer's point of view. An overview is given over the basic approaches, including deterministic and statistical methods, and the spectral theory of homogenous turbulence. Both modeling and observational techniques will be discussed. This class is accompanied by a series of exercise sessions, allowing students to work with real oceanic data sets, and to deepen their understanding of the material treated during the lectures. We will also conduct a laboratory experiment, in which turbulence and mixing in a dense bottom gravity current are analyzed.

Fourier Series and Spectral Analysis

Here, you find some supplementary material describing the basic spectral techniques required in turbulence theory and other applications in geophysics.These notes contain a brief introduction on Fourier series and transforms, spectra and co-spectra, filtering, and discrete Fourier transforms (DFT). Some MATLAB routines are provided were these things can be conveniently explored (using the same notation as in the notes).
