''Think of it like a cold beer at a barbecue,'' said Donna Roberts, of the Antarctic Climate and Ecosystems CooperativeResearch Centre at the University of Tasmania. ''It holds onto its carbon dioxide bubbles longer. Remember that 40 percent of all the carbon dioxide going into the oceans goes into the Southern Ocean. It's going to hit high, and hit hard.''Dr Roberts said work on pteropod snails showed distinct acidification effects. ''We're finding evidence that shell structurehas been getting softer since 1997,'' she said.
