Researchers aboard a 2011 cruise found severe damage to shells of Limacina
helicina, a sea snail that plays an important role in the ecosystem of the
California Current off the Pacific coast. Scientists estimate that one-fifth
of the pteropods had damaged shells in preindustrial times, owing to the
natural acidity of the water, and anthropogenic emissions of CO2 made the
water more acidic, more than doubling the number of individuals with damaged
shells.
