(Episode 3, Part B) In this video segment, the U.S. Geological Survey (USGS), Lower Mississippi Gulf Water Science Center (LMGWSC) scientists give a detailed description of how the USGS deploys heavy samplers to collect discrete water samples for suspended sediment, and bed material on large rivers like the Mississippi River.

In this video segment, the U.S. Geological Survey (USGS), Lower Mississippi Gulf Water Science Center (LMGWSC) scientists give a preview of how the USGS is currently working to design a new generation large river sampler. This new sampler will incorporate all functions of previously developed USGS depth and point samplers.

In this video segment, the U.S. Geological Survey (USGS), Lower Mississippi Gulf Water Science Center (LMGWSC) scientists give a detailed description of how the USGS uses Acoustic Doppler Current Profilers, (ADCP) to measure flow along the lower Mississippi River.

Groundwater use from the Ozark Plateaus aquifer system, 1900 to 2010” is a short video showing modeled groundwater withdrawal rates from the Ozark Plateaus aquifer system (Ozark system) in the central United States.

In 1986, Congress directed the USGS to regularly report groundwater-level changes in the High Plains aquifer system. To comply with this directive, the USGS compares water levels measured every two years. By measuring water levels across the entire aquifer in one year, measurements made two years later enable calculation of changes over time.

The USGS recently constructed a computer model of groundwater in the Mississippi embayment. This model was used to simulate the rise or decline of water level in a shallow aquifer. Water from this shallow aquifer is utilized by the agricultural based economy in the area.

The USGS recently constructed a computer model of groundwater in the Mississippi embayment. This model was used to simulate the rise or decline of water level in a deep aquifer. Water from this deep aquifer is utilized to meet the industrial and public supply needs in the area.

As the animation begins, the land surface of the Mississippi embayment fades away to reveal underground geologic formations (shown as shades of blue, brown, and gray surfaces). A slice deep into the earth cuts off the eastern half of the embayment so we can peer into the formations (aquifers) beneath the surface.

A groundwater-flow model of the Mississippi embayment was used to evaluate changes in water-level altitudes after the addition of wells that simulate potential future pumping from the Sparta aquifer in the Bayou Meto-Grand Prairie area of eastern Arkansas (shown within the black outline) for the 30-year period from 2007 through 2037.

Water, oil, and gas wells (shown as green lines) are drilled to hundreds or thousands of feet below land surface in an area known as the Mississippi embayment. Information gathered from these wells was used to create a 3D computer model of underground formations.
