Passive acoustic analysis using ML in Cook Inlet, AK

Passive acoustic data is analyzed for detection of beluga whales and classification of the different signals emitted by these species. Detection and classification are done with an ensemble of 4 CNN models and weighted scoring developed in collaboration with Microsoft. Results are being used to inform seasonal distribution, habitat use, and impact from anthropogenic disturbance within Cook Inlet beluga critical habitat. The project is aimed to expand to other cetacean species as well as anthropogenic noise.
