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.
