Acidification of the Antarctic Ocean is corroding the shells of some marine snails (pteropods) around Antarctica according to a study by the British Antarctic Survey (BAS).

“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 (BAS) and co-author of the report.
