### Impact des ondes de relief dans la circulation océanique

The Southern Ocean (SO) is home to some of the strongest of the world’s ocean currents. Recent observations and numerical experiments suggest that a fraction of the energy of SO currents is (...)

### Internal wave–boundary layer coupling for a disc oscillating in a density-stratified fluid

A horizontal circular disc oscillating in a density-stratified fluid radiates internal gravity waves. Viscosity affects both the propagation of the waves through the fluid and their generation at (...)
