Nature Geoscience. Holgerson is a David Smith Conservation Research Fellow in the Department of Environmental Science and Management at Portland State University. Traditionally small inland ponds have been excluded from carbon emissions studies because they are difficult to quantify globally and were assumed to contribute minimal levels of emissions given their small size relative to lakes. Holgerson’s paper challenges those assumptions, showing that while small ponds account for only about 9% of inland waterways by surface area, they contribute approximately 15% of carbon dioxide and 41% of methane emissions from inland waters. Holgerson’s paper documents work conducted while in a Ph.D. program at Yale University. The award will be presented at the ASLO Summer Meeting in Victoria, British Columbia in June 2018.   This article appeared on the Eureka Alert website at https://www.eurekalert.org/pub_releases/2017-12/psu-prw122817.php]]>
