From underwater sounds to marine ecology and environmental management

How to use marine soundscapes as a relevant proxy of environmental status and dynamics of coastal marine ecosystems
The 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 environmental status and anthropogenic pressures.
The second objective is to develop protocols to measure marine soundscape and appropriate algorithms to process acoustic databases. The third objective is to demonstrate that the acoustic proxies may be used for environmental management and decision making by end-users.
  • 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
  • The gateway with the network CALME to decline the SEACOUTIC outputs for the monitoring of the Western Mediterranean coastline.
