Unified Interior Regions

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect in the infrared

Groundwater in aquifers between layers of poorly permeable rock, such as clay or shale, may be confined under pressure. If such a confined aquifer is tapped by a well, water will rise above the top of the aquifer and may even flow from the well onto the

My neighbor's driveway with some water on it... not very exciting, but it is an excellent example of how groundwater flows underground and can seep back to the land surface. This simple process demonstrates one of the basic aspects of the water cycle.

 This picture really demonstrates why there is water in many streams even after long periods of no rainfall. You

An important conservation strategy for climate change is to enhance and maintain regional habitat connectivity for the long-term viability of wildlife populations. Modeling habitat connectivity for wildlife species often results in a mapped network of linkages between habitat patches. A critical next step is to determine which of those linkages are priorities for

David Stillwell, USGS hydrologic technician, performs a discharge measurement to help document and forecast flooding caused by Hurricane Florence at Long Creek in Rhyne, North Carolina on Sept. 16. 

Before a hurricane, USGS Scientists undertake a data collection effort of a grand scale. They install a temporary mobile network of sensors along the coasts to collect additional data on the intensity of storm surge, one of the most dangerous elements of a hurricane. This effort provides critical information that allows various USGS partners and emergency responders to

Image of the Week: Okefenokee National Wildlife Refuge Fire

Landsat 8's Operational Land Imager captures the scene as many acres burn in the Okefenokee National Wildlife Refuge.

Series Description:
"Image of the Week" is a series of videos produced by the USGS Earth Resources Observation and Science (EROS) Center featuring remotely sensed imagery of the

A wildfire ignited by lightning in the Okefenokee National Wildlife Refuge on April 6, 2017, is persisting into May. Hot, dry weather and extremely dry fuels are making the fire difficult to contain. As of May 22, the blaze, also called the West Mims Fire, had burned 152,478 acres.

Freshwater springs on the land's surface are fed by groudwater findings its way to the surface. But, groundwater levels go up and down depending on the supply of water from precipitation and flow through the
