A new study has found that whale songs can act as a barometer for the effects of climate change on ocean ecosystems.

Ultrasonic sounds are high-frequency sound waves that exceed 20,000 hertz, a range far beyond what the human ear can detect.

Scientists deploy underwater microphones called hydrophones to study and track baleen whales, which communicate over long distances through sound. In the new paper, researchers monitored songs ...

"Using sound recordings to monitor whale populations isn't new," said lead author Marissa Garcia of the Cornell Lab of Ornithology's K. Lisa Yang Center for Conservation Bioacoustics. "What makes ...

Whales sense their surroundings largely through sound and create complex vocalizations, or songs, when they’re searching for mates and food. Scientists at the Monterey Bay Aquarium Research ...
