The Colloquium will be organized in the following sessions:

1. Mixed layer and frontal instabilities - dynamical understanding and impacts
2. Submesoscale transport - vertical and lateral transport dynamics, subduction, stirring
3. Remote sensing of submesoscale dynamics - surface topography, ocean temperature and color
4. Air-sea interaction at the submesoscale - feedbacks and interactions between submesoscales and air-sea exchange and on ocean and atmosphere boundary layer turbulence
5. Multiscale interactions - energy cascade, cross scale interaction, climate impacts
6. Physical-biological interactions - implications for biogeochemistry, productivity, dispersion and export, and ecosystem dynamics
7. Submesoscale dynamics and topography - coastal submesoscales, interaction with topography and the bottom boundary layer
8. Submesoscale-wave interaction - Internal waves, and wave-front/eddy interactions
