Extracting foraging behavior from passive acoustic monitoring data to better understand harbor porpoise ( Phocoena phocoena ) foraging habitat use
Abstract For odontocetes, passive acoustic monitoring (PAM) can be used to differentiate between occurrence and foraging through analysis of click characteristics. Feeding buzzes and navigation/searching echolocation clicks of harbor porpoise ( Phocoena phocoena ) were differentiated within C‐POD da...
