USGS Continuous Nutrient Monitoring in the Mississippi River Basin

USGS “supergages” are very complex. Continuous concentrations of nutrients and streamflow are measured at supergages and the information is available to the public in real-time. A network of supergages are very important in the Mississippi River Basin for assessing the changes in the amount of nutrients that are transported to the hypoxic zone in the Gulf of Mexico. By

The Phragmites Adaptive Management Framework (PAMF)

This is an introductory video to an adaptive management approach for the invasive plant Phragmites australis in the Great Lakes basin. An adaptive management framework is an iterative process of robust decision making aimed at reducing uncertainty over time, for a variety of stakeholders with differing backgrounds and interests, via system monitoring.
