Ponds Found to Take Up Carbon Like World's Oceans

Research led by Iowa State University limnologist, or Lake Scientist, John Downing finds that ponds around the globe could absorb as much carbon as the world's oceans.

Professor Downing found that constructed ponds and lakes on farmland in the United States bury carbon at a much higher rate than expected; as much as 20-50 times the rate at which trees trap carbon. In addition, ponds were found to take up carbon at a higher rate than larger lakes.

"Aquatic ecosystems play a disproportionately large role in the global carbon budget," Downing said. "Despite being overlooked in the past, it's small bodies of water that are important because they take up carbon at a high rate and there are more of them than previously thought. The combined effect is that farm ponds could be burying as much carbon as the world's oceans, each year."
