Mussels and Oysters Endangered by the Acidification of the Oceans

Since the beginning of the industrial age the ocean has absorbed about half of all anthropic carbon dioxide (CO2) emissions into the atmosphere. This has led to an acidification of sea water. Frédéric Gazeau, a scientist at the Netherlands Institute of Ecology, and his colleagues, including Jean-Pierre Gattuso, Director of Research at the Oceanographic laboratory at Villefranche-sur-Mer (CNRS/Université Pierre et Marie Curie) have examined the reaction of oysters and mussels cultivated in Europe to this acidification of the oceans. The results, published in the review Geophysical Research Letters, are beyond doubt. They show for the first time that these economically important molluscs will be directly affected by the radical change underway in the chemical composition of sea water.
