RISING concentrations of acid in the Southern Ocean caused by greenhouse gases are damaging the ability of some sea creatures to form shells, posing a serious threat to marine life, a study by Australian scientists has found.
One of the study's authors, Dr Will Howard, said the findings were the first evidence from nature, rather than a laboratory, that the acidification of the Southern Ocean will potentially have a big impact on marine life.
