BENTHOSCOPE2

Understanding and monitoring of marine renewable energies impacts on the benthic compartment via a measurement platform dedicated to passive acoustic

Project description

The project BENTHOSCOPE2 aims to develop an operational observation method to quantify and assess the effects of marine renewable energies (MRE) projects on the benthic compartment. This method will use the sounds produced by soniferous species (biophonie) of the benthos as indicators of population health status.
  
BENTHOSCOPE1 allowed the development of relevant and innovative acoustic tools in the context of MRE. ENTHOSCOPE2 will implement these tools in a BACI approach (Before/ After Control/Impact) for impact assessment studies and realize an annual monitoring of a chosen site. The project offers to develop a multidisciplinary measurement platform prototype for the monitoring of environmental parameters in order to interpret sounds and describe the living conditions of the studied benthic fauna.
  
The project will also improve the understanding of MRE acoustic impacts, as well as cumulative ecosystem impacts from the predominant pressures existing before the introduction of MRE devices: i.e. deposition of dredged material, fisheries, climate change, etc.

Objectives

  • Better understand the MRE acoustic impact.
  • Develop a method of passive acoustic monitoring to assess the potential effects of MRE projects on the benthos.
  • Provide a multidisciplinary measurement platform.
  • Submit a study methodology optimising impact assessment procedures.
