Career and research

Walter Anthony has conducted research projects in Russia, Germany, Central America and the United States. During her master's research, Walter Anthony worked on the biogeochemistry of an invasive aquatic plant, Eurasian Watermilfoil. In 2007, Walter Anthony started an International Polar Year Postdoctoral Fellow at the University of Alaska in Fairbanks Walter Anthony's current research focuses on methane and carbon dioxide emissions from arctic and temperate lakes and wetlands in Alaska and

(permafrost thaw), industrial plant emissions, geology, and changes in lake area. By capturing methane flowing from lakes into the atmosphere, Walter Anthony estimated up to 2.5 Pg of carbon was released into the atmosphere during the previous 60 years. In the ''New York Times'', Walter Anthony describes first finding bursts of methane escaping from lakes in Siberia and bubbling out of lakes in Alaska and Greenland. Walter Anthony, who is fluent in Russian, works as project coordinator at Chersky for joint Russian-U.S. projects over the International Polar Year, aiming to network arctic observatories in Alaska and Russia for long term monitoring of climate change in cold regions.
