The USGS is bringing expertise in the use of airborne electromagnetic (AEM) surveys to support groundwater studies. Like medical imaging allows us to non-invasively measure inside the human body, AEM surveys help to investigate Earth's subsurface without the need for expensive drilling.

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.

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.

This is a timelapse video of a dye tracer study at Brandon Road Lock, a U.S. Army Corps of Engineers (USACE) facility in Joliet, IL, on the Des Plaines River on October 20, 2015.

This video portrays two areas near the Brandon Road Lock and Dam, a US Army Corps of Engineers facility in Joliet, IL. This video was collected as the lock was emptied through the downstream valves, refilled with water, and then emptied again. This data collection is supporting efforts to combat the spread of invasive Asian carp into the Great Lakes Basin.
