Big science happening at Itasca! We are thrilled to celebrate Iowa State University geochemist Elizabeth (Betsy) Swanner, and her research group, whose work on Deming Lake contributed to a study just published in Science Science Magazine! For years, Betsy and her team have made Itasca Biological Station their homebase for research on Deming Lake, a rare, permanently stratified Lake, where deep waters never mix with the surface. This unique, low oxygen environment, makes it an exceptional place to study aquatic processes. Samples collected at Deming helped an international research team demonstrate a more precise way to measure denitrification – the natural process through which microbes convert nitrate into nitrogen gas. The new method could help scientists understand nitrogen cycling and water quality. We’re proud that Deming Lake continues to contribute to scientific discovery, and that Itasca Biological helps make this kind of research possible.
