In this “Ecoustics” session, the underwater acoustic landscapes will be considered as a proxy for the structure, functioning and dynamics of marine ecosystems. If events of ecological interest are noisy and/or drive the emission of a sound source, the measurement and analysis of acoustic landscapes makes it possible to obtain a set of valuable environmental knowledge. "Ecoustics" will show that passive acoustics allows to describe the activity rhythms of benthic soniferous invertebrates (like marine mammals) at either individual, population and assemblages levels and to deduce the ecological properties of the objects heard. In addition,“Ecoustics” will be of interest in measuring in the laboratory and in situ the impact of anthropogenic noise on behavior or on the lifecycle of invertebrates.
