India, Jan. 16 -- Under high, very high emissions scenarios, there will be widespread aragonite undersaturation, implying unstable conditions

A new study has raised concerns about the rising acidity levels of the continental shelves in Antarctic Marine Protected Areas (MPA) under high levels of greenhouse gas emissions. Carbon emissions from human activities may be vertically mixed with ocean waters in coastal regions, resulting in severe acidification at all water levels, it suggested.

Shallow, underwater areas extending from the edge of continents known as continental shelves are expected to see more severe acidification than the open ocean. The study, Severe 21st-century ocean acidification in Antarctic Marine Protected Areas , was p...
