In this photo, researchers Erin K. Eberhard and Amy M. Marcarelli from Michigan Tech are taking samples at 1 of 15 study locations in five areas around Lake Superior and Lake Huron. This wetland is located in Houghton, Michigan, along the portage canal that connects to Lake Superior. They are investigating areas where wetlands, lakes, and streams come together to better understand how different characteristics of this interface regulate the nitrogen cycle.
