Comments Off on Quieter Oceans Offer a Rare Chance to Listen
WOODS HOLE, Massachusetts, April 21, 2021 (ENS) – Coronavirus pandemic travel restrictions and economic slowdowns slammed the brakes on human activities in the oceans starting last spring and ongoing. Noise levels are down as cargo ships, cruise ships, and seafloor exploration vessels have slowed or stopped their operations.
The relative silence creates a unique moment for scientists to begin a time-series study of the impacts of human sounds on marine life they have planned for years.
Using hydrophones, microphones that detect sound waves underwater, the study will measure ambient sound in hundreds of ocean locations to reveal variability and changes in intensity at a range of frequencies.
