From underwater sounds to marine ecology and environmental management
AboutHow to use marine soundscapes as a relevant proxy of the health and dynamics of coastal marine ecosystems
ObjectivesThe first objective of SEACOUSTIC is to show that marine soundscapes (biophony, anthropophony) may be used to build a set of reliable acoustic proxies of:
- coastal marine ecosystems (diversity, richness, abundance of marine invertebrates, fishes and marine mammals, functional uses of the sites, spatial and temporal trends, ecosystem health),
- anthropogenic activities affecting ecosystems,
- the link between the ecological condition and anthropogenic pressures.
- The integrative approach of soundscape ecology : underwater sounds as a single input to produce multiple outputs on marine fauna and anthropogenic activities
- The focus on key coastal habitats : seagrass meadows, rocky and coralligenous reefs
- The access of a variety of field sites to develop our methods and calibrate our proxies
