LCMAP Assessment: Florida Phosphate Mining

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.

Freeport McMoRan-Safford Mine Groundwater Monitoring

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.

Changes in Gravity used to Quantify Groundwater-Storage Change in the Tucson AMA

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.

Coastal Storms

U.S. Geological Survey scientists study our coasts to understand how they respond to storms today. But rising sea levels and a changing climate will alter these natural cycles in the future. This geonarrative features research used to predict flooding now and into the future.

National Shoreline Change

Exploring Shoreline Positions of the United States From the 1800s To The Present. Beach erosion is a chronic problem for many coastal areas of the United States. This geonarrative explains how the USGS derives shorelines from various data
sources, and how shoreline change rates are generated from these data.

Barrier Islands

U.S. Geological Survey Researchers Monitor Barrier Islands.  This geonarrative features research used to monitor Barrier islands which are narrow stretches of sand deposited parallel to the shoreline, are inherently valuable ecosystems. They protect estuaries and lagoons that help reduce coastal erosion, purify the water, and provide habitat for fish and birds.

Coastal Wetlands: The State and Future of a Precious Resource

Coastal wetlands, and salt marshes specifically, are simultaneously geomorphic and biologic systems. They proliferate across a narrow range of elevation, water level, and salinity conditions. Salt marshes rely on their own growth and sediment input to maintain or increase their extent, whereas physical forces such as waves and sea-level rise tend to reduce it.
