Méthodes avancées en océanographie

Dernière mise à jour le 27 février 2024

Présentation

This course focuses on some major physical oceanic processes (waves, eddies and meridional overturning circulation) by emphasizing how they work. To develop this understanding, the course uses two complementary approaches of physical oceanography: numerical modelling and observations.

Pré-requis nécessaires

fluid mechanics 1, waves, data analysis 1

Objectifs

Develop your physical insight on how waves and eddies work in the ocean. Apply theoritical knowledge to interpret numerical results and use numerical results to better understand the theories.

Compétences visées

acquire specialized thematic knowledge in marine physics
apply analytical and numerical theories and tools to thematic problems
present one’s results

Descriptif

The course is organized in two equal parts, each evaluated in the form of a final report.

Part 1 Waves and eddies

propagation of linear waves (surface waves, inertia-gravity waves, internal waves),
basic eddy dynamics (self transport, merging, mirror effect),
one layer quasi-geostrophic dynamics on the beta plane (westward drift, gyre, Rossby waves).
classes (3h long) blend lectures and numerical practicals (Python codes) that allow to interact with the processes and see them in action.

Part 2 Observing the ocean In situ measurement

Mixing and Atlantic meridional overturning circulation
Rapid monitoring of the Atlantic meridional overturning circulation
Argo: Heat content and Circulation
Models and Observations
