Acoustic monitoring
Minimizing operations impact on marine life
Loud noises produced during offshore industrial activities can affect marine mammals, causing physical and physiological impacts, behavioral disturbances, and indirect effects related to changes in prey availability.
Regulations typically require monitoring of marine mammals before and/or during these activities to implement mitigation measures that minimize potential acoustic impacts.

Ambient noise monitoring
Marine mammal monitoring
During offshore construction, dredging, or seismic surveys, passive acoustic monitoring (PAM) systems detect the presence of marine mammals by capturing their vocalizations. These systems trigger alerts to temporarily halt operations, reducing the risk of disturbing or harming protected species.
Detect, identify and locate marine mammals
Track marine mammal movements for weeks around the area of interest

Ambient noise monitoring
Acoustic monitoring systems are used to continuously measure underwater noise levels generated by human activities such as shipping, construction, and industrial operations. These measurements help assess the acoustic footprint of different sources and evaluate their potential impact on marine life.
Establish guidelines to minimize disturbances and protect underwater ecosystems
