Influence of Sea-Level Rise on Wetland Vegetation Community Structure, Primary Productivity, Organic Matter Decomposition and Carbon Storage

This study will employ a space for time substitution to show long-term effects of rising sea-level and increasing salinity on vegetation community structure, primary production and decomposition. Productivity and decomposition rates will be estimated for four wetland plant community types defined by salinity zones and dominant plant species.

Soil Properties and Geochronology in Barataria Basin, Louisiana

Will wetland vertical accretion rates be enough to keep up with the predicted rates of sea level rise? USGS looks at soil properties and geochronology in Louisiana wetlands.

Surface Water Hydrology and Nitrate Dynamics in Delta Islands of Prograding Wax Lake Delta, Louisiana

The Wax Lake Delta is an ideal ecosystem to study the effects of a large-scale river diversion on the biogeochemistry of coastal wetlands, and the capacity of these wetlands to assimilate nutrients delivered by these diversions. USGS works to develop a better understanding of surface water hydrology and nitrate dynamics in this area.

Monitoring Effects of Barrier Island Restoration on Piping Plovers in Louisiana

The federally threatened piping plover relies on sand-beach habitat year-round for nesting, foraging, and roosting, habitat that is particularly vulnerable to loss and degradation from coastal development, recreation activities, erosion, and sea-level rise.

Water Resources of Louisiana’s Parishes

The USGS is summarizing basic information on water resources for each parish in Louisiana and presenting the information in fact-sheet format. Information presented includes groundwater and surface-water availability, quality, development, use, and trends. These brief summaries of water resources will provide parish officials, local officials and concerned citizens with information needed to...

Assessing the Influence of the Davis Pond Freshwater Diversion on Water-Quality in Waterways and Marshes of Barataria Preserve

In 2002, the Davis Pond Freshwater Diversion began diverting up to 10,000 cfs of Mississippi River water into the waters surrounding the Barataria Preserve of the Jean Lafitte National Historical Park and Preserve. Previously, precipitation, local surface-water runoff, and occasional marine intrusion largely determined quality of surface and marsh porewaters at the Preserve. The new influx of...

Physical soil properties of wetlands, and the hydrology of tidal swamp, tidal creeks, adjacent rivers, and adjacent marshes along the coastal gradient of palustrine, oligohaline, and mesohaline sites in relation to drought, storm, and tidal events

The LaWSC, in collaboration with researchers from the National Wetlands Research Center (NWRC), the NRP program, Auburn University, and Clemson University, is documenting conditions in tidal swamps in Louisiana, Georgia, and South Carolina as a baseline with which to compare future data to assess the impacts of climate change in such areas. Tidal swamps in these states offer an array of...

Water quality monitoring in the Mississippi River Gulf Outlet, the Gulf Intracoastal Waterway, Lake Borgne, and adjacent waterways in southeastern Louisiana, 2009 to 2013

In early 2009, the U.S. Army Corps of Engineers (USACE) constructed a rock barrier across the Mississippi River Gulf Outlet (MRGO), a navigation channel between the Port of New Orleans and the Gulf of Mexico. In August 2008, prior to construction of the rock barrier, the LaWSC, in cooperation with the USACE, began monitoring specific conductance, dissolved oxygen, and discharge in the MRGO to...

Assessment of water quality and soil conditions at the Bayou aux Carpes 404(C) property wetlands

Wetlands in the Bayou aux Carpes area, south of New Orleans, La., currently are isolated from direct inflow of storm water runoff by levees and spoil banks. The USACE is considering removal of a spoil bank that would allow storm-water runoff to flow through and across the wetlands. . The wetlands consist of floating marshes, with a predominately organic substrate, and forested wetlands, some...
