Acoustics of the Sea-NEREIS

The Acoustics of the SEA (SEAc) project developed by Nereis Environnement aimed to develop a demonstrator to characterize underwater ambient noise.
 

A project to monitor the environment

This project to monitor the environment of a Marine Renewable Energy (MRE) production site required that an autonomous tool for recording underwater sounds and storing data at sea be installed. Specific spectral analysis modules and detection algorithms will be used to characterize the ambient noise by classifying its various components. The data collected will be used to model the acoustic footprint of underwater noise in order to estimate the impact of MRE activities on marine fauna.
 

Tests on the SEM-REV

The tests took place throughout April 2018 at the test site. An innovative demonstrator, including a standalone acoustic recorder from the manufacturer OSEAN, and 3 acoustic recorders were installed on site. The conditions at sea were ideal ensuring a smooth installation.
 
NEREIS Environnement is one of the selected projects in the 4th FORESEA call for funding. This is the first project in this programme to be hosted by SEM-REV.
