A high-resolution airborne and ground-based geophysical survey was conducted near Shellmound, Mississippi as part of the Mississippi Alluvial Plain (MAP) Regional Water Availability Study. This geonarrative showcases the geophysical data used in support of this effort, compiles complementary datasets, and provides additional resources to the user.

The 2020 fire season provided stark evidence that wildfires are changing the landscape of America. But when a forest burns, the impacts on water supply and quality last long after the flames go out. Learn more about how wildfires threaten U.S. water supplies – and what we can do to adapt to the complex impacts of hotter and bigger fires.

Florida's Bone Valley is the source for about 60 percent of the phosphate mined in the U.S. for the production of chemical fertilizer. LCMAP data offers insight on the frequent land cover changes that accompany the mining process.

In December of 2007, Freeport-McMoRan Safford Inc. (FMSI) (formerly Phelps Dodge Safford, Inc.) began production at the Safford Mine in southeastern Arizona, about 8 miles north of the town of Safford in Graham County. The long-term role of the USGS at the Safford Mine is to help ensure that the effects of mine-related pumpage on the regional aquifer are known and quantified.

The Tucson Active Management Area (AMA) is a semi-arid region in southern Arizona. Historically, groundwater pumping in the Tucson AMA exceeded recharge for many decades. Gravity-based methods developed by the USGS can be used to directly measure groundwater-storage changes, providing an estimate of total storage change that does not rely on uncertain estimates of inflows and outflows.

The Flycatcher Habitat Viewer was developed to meet the needs of organizations by providing maps of predicted flycatcher breeding habitat throughout its range. Maps are provided from 2013 to present and cover 57 satellite scenes. Maps identify predicted flycatcher habitat based upon the amount of green vegetation within a 120-m radius of each cell, and the size of floodplain within a 360-m radius.
