Understanding Ecosystem Response and Infrastructure Vulnerability to Sea-Level Rise for Gulf Islands National Seashore
USGS researchers will will survey elevation and vegetation in wetlands and vegetated dunes on Horn, Petite Bois, and Ship Islands; Correct the best available lidar-based digital elevation model; estimate inundation for the Gulf Islands National Seashore under various water levels and relative sea-level rise scenarios; and quantify and predict potential marsh migration for the Gulf Islands National...
Vertical Control of Rod Surface Elevation Table (RSET) Benchmarks to Assess Implications of Sea-Level Rise within Texas Coastal Refuges
The USGS will establish Rod Surface Elevation Tables at five National Wildlife Refuges on the Texas coast. This work will support climate adaptation and resilience planning by identifying areas susceptible to loss and degradation due to sea-level rise and extreme climatic events along the Texas Gulf Coast.
Barriers and Opportunities for Landward Migration of Coastal Wetlands along Texas' Upper and Middle Coast
Researchers at WARC will use data and models to produce probabilistic maps of current and future wetland inundation, coastal wetland extent, and coastal and wetland trangression.
Seasonal Surveys of Shorebird and Coastal Waterbird Utilization of Dredged Material Islands in the Baptiste Collette Bayou, U.S. Army Corps of Engineers (USACE) New Orleans District, Louisiana
To assess use of dredge material areas, avian ecologists from USGS WARC are conducting bird surveys across the annual life cycle.
Assessing Environmental Stress in Mature Mangrove Stands: Linkages to Nutrient Loading
WARC Researchers are comparing tree and root growth, soil CO2 flux, and surface elevation change between fertilized and unfertilized mangrove forests to assess the potential impact of increased nutrient loading and to help rate mangrove stand vulnerability.
Wetland Carbon Working Group: Improving Methodologies and Estimates of Carbon and Greenhouse Gas Flux in Wetlands
WARC researchers are working to quantify the impacts of future climate and land use/land cover change on greenhouse gas emissions and reductions.
Wetland Carbon Cycling: Monitoring and Forecasting in a Changing World
WARC's wetland carbon cycle science team is working to improve model parameterizations and formulations and reduce forecast uncertainty in ecosystem modeling.
Understanding Impacts of Sea-Level Rise and Land Management on Critical Coastal Marsh Habitat
To ensure successful restoration of coastal wetlands, WARC researchers will measure carbon cycling processes that indicate ecosystem health and sustainability.
Effects of Saltwater Intrusion on Anuran Occupancy in Big Thicket National Preserve, Texas
WARC researchers sampled anuran populations at sites within Big Thicket National Preserve to explore saltwater intrusion on these populations.
Impacts of coastal and watershed changes on upper estuaries: causes and implications of wetland ecosystem transitions along the US Atlantic and Gulf Coasts
Estuaries and their surrounding wetlands are coastal transition zones where freshwater rivers meet tidal seawater. As sea levels rise, tidal forces move saltier water farther upstream, extending into freshwater wetland areas. Human changes to the surrounding landscape may amplify the effects of this tidal extension, impacting the resiliency and function of the upper estuarine wetlands. One visible...
Geospatially Enabled, Web-based Habitat Reporting Tool to Support Monitoring and Assessment along the Louisiana Shore
The State of Louisiana's Barrier Island Comprehensive Monitoring (BICM) program has partnered with USGS to developed two habitat classifications schemes for monitoring barrier island habitats and habitats in beach-dune systems along the mainland. These schemes builds upon previous BICM habitat mapping efforts.
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.
