Processes Affecting Coastal Wetland Loss in the Louisiana Deltaic Plain
Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline...
Short-Term Water and Suspended-Sediment Fluctuations in a Louisiana Marsh
To determine the timing of and driving forces for sediment suspension and deposition and the effect of impoundment, three self-recording instrument packages were deployed in a section...
Meteorological Forcing on Louisiana Wetlands
The open wetland areas of southern Louisiana are vulnerable to meteorological forcing. On the basis of over one year U.S.G.S. funded measurements of atmospheric pressure, air-sea temperature...
Marsh Submergence vs. Marsh Accretion: Interpreting Accretion Deficit Data in Coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative...
Natural Resource Problem Solving: an Interdisciplinary Approach in Coastal Louisiana
Ecological issues such as coastal wetland loss cannot be adequately addressed by experts in any one particular discipline. After extensive consultation with wetland users and regulators,...
Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...
Production and Decomposition of
Production and decomposition rates were calculated for Spartina patens in a mesohaline coastal marsh in Louisiana. Production was estimated to be 800 g m-2 ur-1 during 1991 and 1,696 g...
Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....
People and Resources Within the Barataria-Terrebonne National Estuary
South Louisiana's geographic complex is a product of two discrete ingredients: one natural and the other cultural, or human. Relief, soils, landforms, rocks, vegetation, climate, and other...
Priority Problems of the Barataria-Terrebonne Estuarine Complex
The Barataria-Terrebonne Estuarine Complex encompasses an area of approximately 3600 square miles within the Mississippi deltaic plain, and consists of system of water bodies and wetlands...
Integration of Remote Sensing, GIS, and GPS Techniques for Monitoring Non-hazardous Oilfield Waste (NOW) Pits in Coastal Louisiana
Non-hazardous Oilfield Waste (NOW) pits exist throughout Louisiana's coastal zone. Though labeled 'non-hazardous,' NOW pits are potentially dangerous to human and environmental interests...
Using GIS to Monitor Wetlands Loss/Gain
This paper represents the work being done at the National Wetlands Research Center (NWRC) for the U.S. Army Corps of Engineers (COE) to monitor wetland change in the Mississippi River...
Using GIS and Image Processing Technology to Assist Wetland Planning, Protection, and Restoration in Coastal Louisiana
Coastal Louisiana has experienced severe wetland loss over the past 30 years. The Coastal Wetland Planning, Protection, and Restoration Act (CWPPRA) of 1990 was created to address the...
Consolidation Settlement Potential in South Louisiana
Primary consolidation is an important cause of wetland loss in active and recently abandoned deltaic plains in south Louisiana. Argillaceous and organic facies are most subject to reduction...
Subsidence Properties of Holocene Sediments: S. La.
As part of a comprehensive USGS-sponsored study of processes that drive subsidence and wetland loss in south Louisiana, two continuously cored deep borings (60 m and 72 m) were acquired...
Salinity Variations in Two Louisiana Estuaries
Salinity variations, on a variety of time scales, are described for two shallow bar-built estuaries of the Louisiana coast. Tidal, sub-tidal, and seasonal scale variations are important...
Effects of Surface Brine Disposal on the Marshes in Coastal Louisiana
In 1986, more than 1 billion barrels of brine were disposed of in Coastal Louisiana. Disposal of brine into surface water body is economically practical but environmentally detrimental....
Resource Extraction Activities in the Coastal Zone?The Impact of Offshore Oil Production on Coastal Communities
There are few studies that examine the impact of offshore oil extraction on social problems, educational attainment and economic health of communities. The results of this study demonstrate...
Myths, Models and Managers of Marine Resources
This paper argues that the assumptions of scientific models are often accepted without verification. Examining the use of Hardin's tragedy of the commons model in the management of marine...
United States National Marine Fisheries Service Role/Contribution in Restoring Coastal Habitats Under the Coastal Wetlands Planning, Protection, and Restoration ACt of 1990
The agency has assembled a diverse team from government, academia, the private sector, and its program staff within the region to develop specific guidelines for identifying and evaluating...
