Acoustic monitoring of beluga whales (Delphinapterus leucas): spatio-temporal habitat preference and geographic variation in Canadian populations
Acoustic monitoring is an effective means by which to study cetaceans, such as beluga whales (Delphinapterus leucas), and can be useful in determining habitat preference and geographic variation among populations. Acoustic monitoring data were analyzed using a combination of automated detection and...
