February 22, 2018

This resource features passive acoustic sound clips of many amazing marine mammals that can be found in Alaska waters.

Listen to Marine Mammals in Alaska Waters

We use passive acoustic techniques to monitor Alaskan waters for marine mammals and the natural and man-made noise in their environment. Passive acoustics means we just listen and record sounds in the ocean, rather than sending sound into the water as in sonar or other active acoustic methods.

Passive acoustic data collected by the Marine Mammal Laboratory provides an invaluable long-term record of marine mammal occurrence and environmental noise during recent rapid climate change and mounting industrial activities.  This data helps establish baseline information critical for making decisions about Alaska’s marine resources.
