Scientific American A Few Fixes Could Cut Noise Pollution That Hurts Ocean Animals Redesigning ship propellors and installing acoustic “curtains” could lower the volume on anthropogenic noise that disrupts ocean life Advertisement Shipping noise and other sounds from human activity in oceans harm numerous marine species, according to a broad new assessment of existing research. The findings, published this month in Science, also include viable solutions some already in use that could buy time to address tougher problems such as ocean acidification and potentially save the lives of imperiled species such as southern resident killer whales, Maui dolphins and Atlantic cod. ....

Wegner Institute Share this article Press release issued: 4 February 2021 Oceans were once filled with the sounds of nature, but overfishing, climate change and human noise have fundamentally changed the natural underwater soundtrack , researchers say. A global team of scientists, including six experts from three UK institutions, has documented how ocean soundscapes have changed, explored all impacts of noise on marine animals and ecosystems, and identified ways to restore a more natural soundscape. The team set out to understand how human-made noise affects wildlife, from invertebrates to whales, and found overwhelming evidence of negative impacts on behavior, physiology and reproduction – causing death in extreme cases. ....
