Whales go quiet during noisy underwater surveys
A new study has shown that whale calls are reduced by as much as 50% in response to seismic surveys, which are commonly used to find oil and gas reserves. Researchers are worried that such surveys could impact vulnerable marine species, which rely on sound for communication, navigation, and foraging...

A new study has shown that whale calls are reduced by as much as 50% in response to seismic surveys, which are commonly used to find oil and gas reserves. Researchers are worried that such surveys could impact vulnerable marine species, which rely on sound for communication, navigation, and foraging. The paper, published in Scientific Reports, reveals how fin whale calls dropped dramatically along a key migratory corridor off northwestern Spain during seismic surveying.
