The Mississippi Alluvial Plain is one of the most productive agricultural regions in the Nation and depends on groundwater for irrigation. The MAP area constitutes the third largest area of irrigated cropland in the United States. The area is approximately 29,000 square miles (19 million acres) and includes parts of the States...
The Challange: The DOI WaterSMART (Sustain and Manage America’s Resources for Tomorrow) initiative is developing data and tools to help water managers identify current and future water shortages, for humans and for freshwater ecosystems. Fishes, for example, can decline in diversity and abundance when streamflow becomes too low, for too long. However, ecologists find that effects...
Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles....
The Daniel Beard Center in Everglades National Park provides the base for most of the field work done on the control of invasive reptiles by USGS Fort Collins Science Center staff. The team works in Everglades National Park, Big Cypress National Preserve, Crocodile Lake National Wildlife Refuge, and other parts of the Greater Everglades Ecosystem focusing on, among other species of concern,...
Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...
Hurricanes bring destructive winds, storm surge, torrential rain, flooding, and tornadoes. A single storm can wreak havoc on coastal and inland communities and on natural areas over thousands of square miles. In 2005, Hurricanes Katrina, Rita, and Wilma demonstrated the devastation that hurricanes can inflict and the importance of hurricane hazards research and preparedness.

Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Each data item represents an individual research product, with some items grouped together as aggregates to show the breadth of the topic and make it easy to explore.

Groundwater Watch is a supplemental tool to NWISWeb and, as such, is able to provide additional benefits to the groundwater community. NWIS is the authoritative database for USGS groundwater data, and NWISWeb is the public interface for these groundwater data. This is information pertaining to the Memphis Area Groundwater-Level Network.
The interactive sea-level rise visualization tool results from a collaborative effort between NOAA's Coastal Services Center, USGS WARC, and USGS Mississippi Water Science Center. The tool illustrates the scale of potential flooding, but not the exact location, and does not account for erosion, subsidence, sediment accretion, or future construction.
MsCIP was developed in 2009 by the U.S. Army Corps of Engineers, Mobile District, in conjunction with other Federal and State agencies, to help reduce future storm damage along the Mississippi Gulf coast. In 2014, in cooperation with the USACE Mobile District, WARC's Advanced Applications Team began development on the MsCIP Data Viewer, an interactive web-mapping environment.
The JEM community of practice is focused on ecological modeling and monitoring across the Greater Everglades, with particular interest in habitats, how various factors affect habitat change, and how the organisms dependent on those habitats respond today and into the future.

Shinn, Eugene A.; Jaap, Walter C.Carbon dioxide (CO2) concentration in the atmosphere has steadily increased from 280 parts per million (ppm) in preindustrial times to 381 ppm today and is predicted by some models to double within the next century. Some of the important pathways whereby changes in atmospheric CO2 may impact coastal wetlands include changes in temperature,...
McKee, KarenWe provide information about the effects of Hurricane Katrina on populations of an invasive fish, the Nile tilapia (Oreochromis niloticus) in southern Mississippi. By resampling areas surveyed before the storm, we attempted to determine whether the species expanded its range by moving with storm-related floods. Additionally, we used rotenone to...

The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding. Click here to learn more about the work the USGS has completed for Hurricane Matthew.
