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.

This year’s Earth Day theme, “Restore Our Earth,” brings to our attention one of the most important parts of contributing to a better future for the ecosystem: emerging green technologies. Until most industries find a way to switch from outdated, harmful processes to sustainable, eco-friendly ones, all protection and conservation efforts are undermined. Green shipping is one of the emerging trends that is set to create massive positive change for marine life. 1 photo
One positive thing that everybody noticed during last year’s health crisis was how quiet everything got. All of a sudden, people all over the world could actually hear all sorts of nature sounds.
âWeâd like the word soundscape to become a lot better known. Sound is light in the oceans. It illuminates the ocean for many animals. They use it to communicate, to hunt, and can be harmed by noise at excess,â Ausubel said.
He and colleagues â including specialists at St Andrews â plan to expand the hydrophone network, particularly in the southern hemisphere, to more than 500 devices. Using modelling and data collaborations with shipping companies and other ocean users, they hope to produce a global map of ocean sound within the coming years. This should reveal important patterns, such as increases in noise along shipping lanes and near oilfields and windfarms, which could prove as important for ocean health and regulation as roadside air pollution monitoring, or water-contamination measurements near factories.
