Résumé

It is assumed within the oceanographic community that anthropogenic noise can affect negatively a wide variety of marine species. To better assess its main source, the shipping noise, the MARS (Marine Acoustic Research Station) station consisting of vertical hydrophone arrays was deployed in the St-Lawrence Estuary along the upstream shipping lane. The station was designed to allow high quality measurement of the ships source levels following the ANSI/ASA S12.64-2009 and ISO-17208-1 standards. It is part of the MARS project which aims to study shipping noise both underwater and onboard ships and to propose reduction methods. Since 2021, a database of over 1000 acoustic signatures have been collected, including 173 high-resolution signatures from partner ships that followed an optimized trajectory for the acoustic measurements. This database will be used by governmental authorities, such as Transports Canada, for decision making regarding the shipping noise and by the scientific community for research purposes.
