Featured Product: Thermal effect of climate change on groundwater-fed ecosystems
USGS scientists, in partnership with scientists at universities, developed tools that natural resource managers can use to forecast the effect of climate change on groundwater temperature at springs and seeps that support critical habitat. Using these tools, scientists identified important processes that control the long-term thermal response of springs and other groundwater discharge to climate change. Groundwater temperature changes will lag surface temperature changes from a changing climate. The rate of change of groundwater temperature can vary by decades depending on local hydrogeologic conditions. View the journal article.

Did you know we can use scientific equipment on planes and helicopters to study groundwater? During the first week of May 2017 USGS scientists used an airborne electromagnetic induction (AEM) tool flown by helicopter to study the Cedar River Aquifer near Cedar Rapids, Iowa. AEM is a geophysical method that enables scientists to see inside the earth, much like how medical imaging lets us see inside the human body. AEM data can help us understand:
- geologic structure,
- distribution of groundwater, and
- water quality.
USGS hydrologists will use the Cedar River Aquifer AEM data collected as they develop a three-dimensional model of the aquifer for the City. For more information about AEM data and groundwater modeling, learn about how USGS used AEM data in the development of a Sioux Falls groundwater flow model.
