Estimating the number of marine mammals using recordings of clicks from one microphone
An important but challenging task is to extract information on the location and/or number of marine mammals present given recordings from an array of hydrophones. Systems such as the Marine Mammal Monitoring on Navy Ranges (M3R) attempt to localize marine mammals as well as to get an estimate of the...
