Acoustic tomography experiment in the Lake of Geneva: winter cooling

Physical limnology in the Lake of Geneva tries to identify the dominant processes of transport and mixing which influence the water quality of the lake. Based on the modelling of sound propagation and its systematic comparison with experimental data, it is shown that the qualification of the major processes controlling hydrodynamics (thermal stratification, internal waves) is possible by the analysis of sound travel times between two sites close to the banks during the cooling season.
