Antarctic Marine Wildlife Is Under Threat From Ocean Acidification, Study Finds 180

A study has found that a decreased pH level in the antarctic is damaging the shells of native wildlife. "Marine snails in seas around Antarctica are being affected by ocean acidification, scientists have found. An international team of researchers found that the snails' shells are being corroded. Experts says the findings are significant for predicting the future impact of ocean acidification on marine life. The results of the study are published in the journal Nature Geoscience (abstract). The marine snails, called "pteropods", are an important link in the oceanic food chain as well as a good indicator of ecosystem health. 'They are a major grazer of phytoplankton and... a key prey item of a number of higher predators - larger plankton, fish, seabirds, whales,' said Dr Geraint Tarling, Head of Ocean Ecosystems at the British Antarctic Survey and co-author of the report."

    a friend of mine just started at portsmouth university, studying marine biology, and we happened to talk about this subject. the situation's actually much worse than being reported here, because the coral reefs are *also* being corroded. given that coral reefs are where the majority of the ocean's life-forms congregate, if that eco-system collapses we're in real serious trouble. i say trouble: the planet's likely to survive, and to re-generate life over the next hundred millenia or so. it's just that humans really won't be around to enjoy being here, that's all.

    Believe it or not, the actual study isn't about ocean acidification. It was tangentially related, but the scientists knew they would get better coverage if they pushed that in that angle. And they were right.
