We used a mandible accelerometer to document feeding events in two free-ranging adult female Weddell seals in Atka Bay, Antarctica. Using spectral analysis, we isolated several patterns in the mandible acceleration data. The shorter, un-attenuated signals are thought to represent feeding. The longer...
