Alabama Barrier Island Restoration Assessment at Dauphin Island
Dauphin Island, Alabama, is the only barrier island providing protection to much of Alabama's coastal natural resources. Severely impacted by repeated extreme events, like Hurricane Katrina and Deepwater Horizon oil spill, USGS and partners are conducting a joint study to evaluate the feasibility of certain alternatives to increase resiliency and sustainability of the island.
Spatial Analysis of Coastal Wetlands Planning, Protection and Restoration Act Projects
As the first federally mandated restoration program, Louisiana enacted the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) to address Louisiana’s land loss crisis.
Identifying and Projecting Water Quality Outcomes of Canal Backfilling Restoration at Jean Lafitte National Historical Park and Preserve
USGS researchers and their partners will develop a coupled hydrodynamic and water quality modeling system; calibrate and validate the models; assess and predict outcomes of a canal backfilling restoration project on key water quality attributes; and run the modeling system under a suite of scenarios reflecting changing environmental conditions.
Nekton References and Targets: Assessing the Abundance and Density of Fish and Invertebrates Associated with Louisiana’s Marsh Habitat
The National Oceanic and Atmospheric Administration (NOAA) is leading a Monitoring and Adaptive Management (MAM) activity with USGS collaborators to establish reference ranges and restoration targets, assess data gaps for focal nekton species and/or guilds associated with Louisiana’s estuarine and coastal habitats, implement the fixed-area sampling strategy to quantify fishes and invertebrates...
Quantifying Changes in Wetland Area and Habitat Types in the Deepwater Horizon Louisiana Restoration Area 1985-Present with Remote Sensing
USGS researchers will quantify wetland change and wetland vegetation community type change through the analyses of aerial vegetation survey data and investigate potential relationships between Normalized Difference Vegetation Index (NDVI) and marsh elevation change.
A Roadmap for Developing Resilient Coastal Shellfish Populations: Using Spatial and Process-Based Modelling for Restoration Under Current and Predicted Future Water Quality Conditions
Estuaries support valuable recreation, fisheries, and aquaculture and are dependent on healthy and vibrant ecosystems. Along the northern Gulf of America, estuaries sustain local economies through their high productivity. They also receive over 50% of the United States watershed discharge, and water quality within these estuaries is impacted by local management actions. Within these...
Model Improvements for Louisiana’s 2023 Coastal Master Plan
The Louisiana Coastal Protection and Restoration Authority’s Coastal Master Plan is a blueprint for responding to environmental changes. As part of the agency’s continued engagement, USGS supports model developments and improvements for the 2023 Coastal Master Plan.
Identification of Hydrologic Controls on Coastal Spartina patens Marshes and Optimal Hydrological Conditions for Sustainable Mottled Duck Habitat
Mottled ducks rely on the coastal marshes of the Texas Chenier Plain, which are considered among the most critically endangered habitats in the United States. USGS scientists are evaluating what might be contributing to the degradation of high-quality mottled duck habitat to better understand the causes of habitat loss and subsequently mitigate those losses.
Mississippi Coastal Improvements Program (MsCIP)
In 2009, the Mississippi Coastal Improvements Program (MsCIP) was developed by the U.S. Army Corps of Engineers (USACE), Mobile District in conjunction with other Federal and State agencies, to help reduce future storm damage along the Mississippi Gulf Coast. The Comprehensive Plan for MsCIP includes restoring the Mississippi barrier islands and over 3,000 acres of wetland and coastal forest...
Alabama Barrier Island Restoration Assessment
This project is a collaborative effort between the USGS, U.S. Army Corps of Engineers (USACE), and the State of Alabama funded by National Fish and Wildlife Foundation (NFWF) to investigate viable, sustainable restoration options that protect and restore the natural resources of Dauphin Island, Alabama. The project is focused on restoration options that protect and restore habitat and living...
Assessment of Wetland Area Change and Shoreline Erosion Due to Hurricane Sandy
Significant damage to coastal communities and surrounding wetlands of the north Atlantic states was caused by Hurricane Sandy in late October 2012, mostly tied to an associated storm surge of record extent and impact.
Investigation of Causal Mechanisms of Coastal Wetland Change in Coastal Louisiana
This task will involve the compilation of all data sources and expert knowledge of causal mechanisms of specific areas of wetland loss throughout the coastal zone of Louisiana.
Land Area Change in Coastal Louisiana (1932 to 2010)
Coastal Louisiana wetlands make up the seventh largest delta on Earth, contain about 37 percent of the estuarine herbaceous marshes in the conterminous United States, and support the largest commercial fishery in the lower 48 States.
