ABSTRACT
During the last 20 years great advances have been made in instrumentation to measure the different dynamical process of natural aquatic systems (internal waves, plumes, mixing processes including convection and double-diffusion, boundary layer dynamics, air-sea interactions, physical patchiness, sediment transport …). Knowledge obtained from the research associated with these measurements serves to better understand the ecology of these systems, contamination distribution, and to improve numerical models for better predictions. When long time series of data are available, global change can be traced.
