Ocean Acidification Reduces Size of Clams
This figure appears in chapter 24 of the Climate Change Impacts in the United States: The Third National Climate Assessment report.
The 36-day-old clams in the photos are a single species, Mercenaria mercenaria, grown in the laboratory under varying levels of carbon dioxide (CO2) in the air. CO2 is absorbed from the air by ocean water, acidifying the water and thus reducing the ability of juvenile clams to grow their shells. As seen in the photos, where CO2 levels rise progressively from left to right, 36-day-old clams (measured in microns) grown under elevated CO2 levels are smaller than those grown under lower CO2 levels. The highest CO2 level, about 1500 parts per million (ppm; far right), is higher than most projections for the end of this century but could occur locally in some estuaries.
