Unified Interior Regions
South Dakota
Surface water and groundwater provide important water supplies in South Dakota. Major rivers include the Big Sioux, James, Cheyenne, and Missouri Rivers. Key aquifers include the Dakota, Madison, Minnelusa, and Big Sioux aquifers. The Dakota Water Science Center has many studies that focus on these resources as well various other national and international studies.

Cedar Rapids Geophysical Survey - Team with Sensor
A helicopter towing a large, cylindrical sensor will make low-level flights over parts of Cedar Rapids, Iowa, as part of a groundwater survey in May 2017.
The flights will collect and record underground geologic measurements to help the U.S. Geological Survey better determine groundwater resources in the Cedar River Aquifer. The helicopter, operated by

Changes in Canopy Cover with NASA MODIS Leaf Area Index Data
Did you know that tree canopy cover can be measured from space? The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites can do just that by providing data that are used to calculate Leaf Area Index (LAI). LAI is a measurement of green leaf area in broadleaf tree canopies and needle surface area in coniferous tree canopies.
Annual Progression of Global Vegetation with NASA MEaSUREs VIP
The seasonal progression of global vegetation is driven by the tilt of the Earth's rotational axis and its annual orbit around the Sun. In turn, global seasonality drives major changes in important environmental factors such as global atmospheric carbon dioxide concentrations. This data visualization illustrates this phenomenon using weekly Enhanced Vegetation Index 2 (
