A Colorado Lake with Elevated Nitrogen

Caption: Scientist Jim Elser (Arizona State University) is sampling Green Lake 5, located at the Niwot Ridge Long-term Ecological Research (LTER) site in the Front Range of the Colorado Rocky Mountains. Like other lakes in the Front Range, this lake receives elevated inputs of atmospheric N deposition due to transport of polluted air from urbanized areas and from high intensity agricultural operations.
