Learning unit contents

The course focuses on the description and understanding of the interactions between marine physical and biogeochemical processes from the small to the large space and time scales.
Table des matières:
Chapter I : The geohydrodynamic context

  • Introduction
  • Space and Time scales, spectral window
  • Mathematical modelling


Chapitre II The geohydrodynamic variability
I The internal forces
  • A. The molecular effects
  • B. The stratification and internal waves
  • C. The Coriolis effect
  • D. The earth curvature effect

II The external forces
The heat exchange at the air sea interface

Chapitre III: Processes on a scale of less than 1 kilometer
  • Biology and boundary layers
  • Vertical structure of the open ocean: biology of the mixed layer
  • Vertical structure in coastal waters: freshwater run-off and tidal mixing.

Chapitre IV: Processes on a scale of 1-1000 kilometers
  • Vertical structure in coastal waters: coastal upwelling regions
  • Fronts in coastal waters
  • Tides, tidal mixing, and internal waves
