Passive acoustic detection and localization of whale: effects of shipping noise in Saguenay - St Lawrence marine park
WOS International audience The performance of large-aperture hydrophone arrays to detect and localize blue and fin whales’ 15–85Hz signature vocalizations under ocean noise conditions was assessed through simulations from a normal mode propagation model combined to noise statistics from 15960h of re...
