Oceanography
Teachers: Achim Wirth and Guillemette Ménot
Class type :18h CM, 12h TD
Course content
- Chemical and physical parameters of the oceans and their repartition with depth and spatially
- Measurements of these parameters: in-situ and remote methods
- Control by insolation
- Links between atmospheric and oceanic circulations, Ekman transport, influence of Coriolis force, theory of Sverdrup, Gulf Stream and western border currents
- Global oceanic circulation: deep water formation, tracers of the deep circulation (T-S, 14C, anthropogenic compounds: CFC, nuclear tests 60's...), Stommel’s model
- Chemistry of the oceans: impact of circulations on chemical elements, links with biological activity (nutriments, particle fluxes)
- Variations of oceanic circulations during the Quaternary, impact on climate. Methods to document past variations (δ13C, 231Pa/230Th, εNd)
