The effect of the sea absorbing increased carbon dioxide in the air has damaging consequences for the noisy snapping shrimp and marine life in coastal rock pools.<\/strong><\/div>\n

LONDON, 6 April, 2016<\/em>\u00a0\u2013 The slow change in water chemistry as more and more atmospheric carbon dioxide dissolves in the sea and causes acidification could make the oceans much less noisy and slow the growth of life at the sea\u2019s margins.<\/p>\n

In one study, Australian scientists warn that as the acidity levels grow, the\u00a0snapping shrimp may grow ever quieter<\/a>. And in another study, Californian scientists have tested the\u00a0water chemistry in coastal rock pools<\/a>\u00a0and discovered that they become most corrosive at night.<\/p>\n

The snapping shrimp is the\u00a0loudest invertebrate in the ocean<\/a>. It forms bubbles in its snapping claw and uses this noise-making tool to warn off predators. And it can generate up to 210 decibels of noise, with important consequences for other creatures in coastal ecosystems.<\/p>\n

Cracking sounds<\/strong><\/p>\n

\u201cCoastal reefs are far from being quiet environments \u2013 they are filled with loud cracking sounds,\u201d says Tullio Rossi, a marine acidification specialist\u00a0at the\u00a0University of Adelaide\u2019s School of Biological sciences<\/a>. \u201cShrimp choruses can be heard kilometres offshore and are important because they aid the navigation of baby fish to their homes. But ocean acidification is jeopardising this process.\u201d<\/p>\n

He and colleagues\u00a0report in the Proceedings of the Royal Society B<\/a>\u00a0that they tested the shrimps under laboratory conditions of acidity predicted for the end of the century, and they found that both the frequency and volume of the snapping noises diminished.<\/p>\n

The researchers also made field recordings at carbon dioxide-rich submarine volcanic vents, and observed the same pattern. They believe that the\u00a0change of ocean pH levels<\/a>\u00a0affects behaviour, rather than impairing physiology.<\/p>\n
