“#Under the sea, humans have changed ocean sounds<\/strong>”<\/p>\n

WASHINGTON \u2014 Not only are humans changing the surface and temperature of the planet, but also its sounds \u2013 and those shifts are detectable even in the open ocean, according to research published Thursday.<\/p>\n

Changes in the ocean soundscape affect wide swaths of marine life, from tiny snapp<\/a>ing shrimp to huge right whales, the researchers found.<\/p>\n

\u201cSounds travel<\/a> very far underwater. For fish, sound is probably a better way to sense their environment than light,\u201d said Francis Juanes, an ecologist at the University of Victoria in Canada and a co-author of the paper in the journal\u00a0Science.<\/a><\/p>\n

While light tends to scatter in water, he said, sounds travel much faster\u00a0through water<\/a>\u00a0than through air.<\/p>\n

Many fish and marine animals use sound to communicate with each other, to locate promising locations to breed or feed and possibly to detect predators. For example,\u00a0snapping shrimp<\/a>\u00a0make a sound resembling popping corn that stuns their prey.\u00a0Humpback whale<\/a>\u00a0songs can resemble a violinist\u2019s melodies.<\/p>\n

But increased noise from\u00a0shipping traffic<\/a>, motorized\u00a0fishing vessels<\/a>, underwater oil and gas exploration, offshore construction and other human activity is making it harder for fish to hear each other.<\/p>\n

The researchers sifted through thousands of data sets and research articles documenting changes in noise volume and frequency to assemble a comprehensive picture of how the ocean soundscape is changing \u2013 and how marine life is impacted.<\/p>\n

Using underwater microphones, scientists can record fish sounds \u2013 which tend to hover around the same low frequencies as shipping traffic noise.<\/p>\n

\u201cFor many marine species, their attempts to communicate are being masked by sounds that humans have introduced,\u201d said Carlos Duarte, a marine ecologist at the Red Sea Research Center in Saudi Arabia and co-author of the paper.<\/p>\n

The Red Sea is one of the world\u2019s key shipping corridors, full of large vessels traveling to Asia, Europe and Africa. Some fish and invertebrates now avoid the noisiest areas, as the sound effectively fragments their Red Sea habitat, he said.<\/p>\n

Meanwhile the overall number of marine animals has declined by about half since 1970. In some parts of the ocean, scientists now record \u201cfewer animals singing and calling than in the past \u2013 those voices are gone,\u201d said Duarte.<\/p>\n

Climate change also influences physical processes that shape ocean sounds, such as winds, waves and melting ice, the researchers found.<\/p>\n

\u201cImagine having to raise your kids in a place that\u2019s noisy all the time. It\u2019s no wonder many marine animals are showing elevated and detectable levels of stress due to noise,\u201d said Joe Roman, a University of Vermont marine ecologist, who was not involved in the paper.<\/p>\n

\u201cWhen people think of threats facing the ocean, we often think of climate change, plastics and overfishing. But noise pollution is another essential thing we need to be monitoring,\u201d said Neil Hammerschlag, a University of Miami marine ecologist, who was not involved with the paper.<\/p>\n

\u201cIf you make something for the ocean, think about how to make it quieter,\u201d he said.<\/p>\n

Sound pollution may be simpler to address than other ocean threats, said the University of Victoria\u2019s Juanes. \u201cIn theory, you can reduce or turn off sound immedia<\/a>tely \u2014 it\u2019s not like plastics or climate change, which are much harder to undo.\u201d\n <\/p><\/div>\n
