Acid Rain Hurting Marine Organisms

U.S. researchers say acid rain’s impact on the world’s oceans is greatest along the coastlines.

The report, published online in the Proceedings of the National Academy of Sciences, said ocean acidification hampers the ability of marine organisms to harness calcium carbonate for making hard outer shells or exoskeletons, which provide essential food and habitat to other organisms.

Ocean acidification occurs when chemical compounds such as carbon dioxide, sulfur or nitrogen mix with seawater, a process which lowers the pH and reduces the storage of carbon.

Study looks at acid rainfall in the ocean

A U.S. study shows that while acid rainfall plays a minor role in ocean acidity, the impact is much greater in the shallower waters of the coastal ocean.

Ocean acidification occurs when chemical compounds such as carbon dioxide, sulfur or nitrogen are produced by power plants and agricultural activities mix with seawater — a process that lowers water pH values and thereby reduces carbon storage.

“Acid rain isn’t just a problem of the land. It’s also affecting the ocean,” said Scott Doney, lead author of the study and a senior scientist at the Woods Hole Oceanographic Institution. “That effect is most pronounced near the coasts, which are already some of the most heavily affected and vulnerable parts of the ocean due to pollution, over-fishing and climate change.”

Acid Rain Has Disproportionate Impact on Near-shore Ocean Waters

The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities–commonly referred to as acid rain–plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal oceans, according to new research.
