Dr. Luc Rainville is a physical oceanographer at the Applied Physics Laboratory, University of Washington. His research interests reside primarily in observational physical oceanography and span the wide range of spatial and temporal scales in the ocean. From large-scale circulation to internal waves to turbulence, the projects he is involved in focus on the interactions between phenomena of different scales. Many of Luc’s projects revolve on finding innovative ways to study the ocean, pushing the boundaries of what we have been able to observe, primarily through sea-going oceanography and autonomous instruments (in particular Seagliders), but also using with remote sensing and modeling.
