Improving our knowledge of the ocean state and its predictability requires a thorough description of the physical processes that are involved in ocean dynamics through a large continuum of scales.

Investigating these processes at different scales in the ocean and at its upper and lower boundaries is the main objective of the OPLC research team at the MIO laboratory. Documenting the interactions between scales is a major focus of the team because such interactions are generally poorly understood and, thus, neglected or empirically represented[Ed.1]  in ocean models.

The perspective of scale interactions dictates the activities of our team, the members of which have skills that cover a wide range of fields in the areas of physical modelling and experimentation. In the context of global change, the environmental and societal applications of the aforementioned fundamental research take a growing role in the activities of the team, with a specific transverse thematic approach now devoted to this research at the MIO laboratory.

Equipment

OPLC team activity relies on a panel of complementary skills in experimentation – observation – and modelling. This is essential for the development of multi-scale approaches which are required for studying the complex dynamics of coastal ocean. A wide variety of measurement technics are mastered and enforced by the OPLC team, namely:

  • HF and VHF radar teledetection for the characterization of sea states and the measurement of water and wind velocities
  • design and deployment of instrumented moorings
  • towed instrumented fishes (MVP, minibat)
  • use of drifting buoys
  • instrumentation of the littoral domain, neighbouring beaches and of the surf-zone
  • use of satellite data (visible and micro-wave frequencies)
  • experiments in wave flumes, oceanic basin, air-sea interaction facility, erodimeter, ...
