Quieter Oceans Offer a Rare Chance to Listen


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. ....

Emerging Ocean Listening Network Will Study Seas Uniquely Quieted by Covid


The Covid-19 pandemic left the oceans quieter than ever in 2020, allowing scientists to analyze the effect human-generated sound has on marine life.
This map from the IQOE-endorsed JOMOPANS project shows the difference between the total noise level and the natural noise level with differences up to 30 decibels (dB). While 30 dB on its own is not loud, the superimposition raises the level significantly higher than natural noise. (Credit: JOMOPANS)
(CN) A unique new study has taken advantage of the momentary pause in human activity in the ocean during the Covid-19 pandemic, as scientists around the world listen for how human-generated noise in the water and a lack thereof affects marine life. ....
