Ondes internes océaniques
Présentation
This course focuses on ocean internal waves. Students will acquire a general knowledge of the dynamics of internal waves in the ocean, the waves properties, their generation mechanisms, the consequences of their possible non-linearity or instability and their role in the ocean and climate system. The course is taught in English.
Pré-requis nécessaires
Pre-requisites
Geophysical fluid dynamics (Fluids 1 and Fluids 2)
Objectifs
On completing this course, students will be able to express the equations governing the evolution of internal waves and solve them mathematically in idealized systems, they will know the important properties of internal waves, and be able to reason physically about their evolution in the ocean.
Compétences visées
ability to analyse and solve a marine physica probleme, using knowledge about internal waves, in a professional or academic frame.
Ability to observe and simplify theory in regard of observations or conversely to establish a measurement plan in view of theory; in particular scale and give orders of magnitude of phenomena for observation, or provide simplified equations
Ability of select and critically analyse bibliographic information to extract a new scientific question; develop critical arguments; use the knowledge of atmosphere-ocean theory to solve an original problem
Be able to solve problems on the field or in a company, taking into account the whole complexity of reality
Communicate orally or by texts, in a scientific manner
