Coastwide Reference Monitoring System (CRMS)
CRMS uses a multiple reference approach to biological monitoring and uses aspects of hydrogeomorphic functional assessments and probabilistic sampling that address the limited effectiveness of the traditional paired-reference monitoring approach in Louisiana. This approach includes a suite of sites that encompass the range of ecological conditions for each stratum, with projects placed on a...
Sea-level and Storm Impacts on Estuarine Environments and Shorelines (SSIEES)
This project assesses the physical controls of sediment and material exchange between wetlands and estuarine environments along the northern Gulf of Mexico (Grand Bay Alabama/Mississippi and Vermilion Bay, Louisiana) and the Atlantic coast (Chincoteague Bay, Virginia/Maryland).
Relation between Plant Community Structure and Function and the Effectiveness of Wetland Restoration Efforts
High rates of wetland loss continue to occur along the northern Gulf of Mexico coast, and this remains an issue of concern to resource managers.
Gulf of Mexico Land Loss Change Assessment: A Cooperative Study with the Bureau of Ocean and Energy Management
Eighty-five percent of the coastal wetland loss in the contiguous United States occurs in the Gulf of Mexico. Documenting and understanding the occurrence of this wetland loss will provide for effective planning, mitigation, and restoration activities.
Long-term Trends in Swamp Tree Growth across Drought and Salinity Gradients along the Northern Gulf Coast
This study will examine the potential effects of climate-change-induced sea level rise, drought and water extraction by examining tree growth patterns across the Gulf Coast, specifically targeting long-term research plots available in the North American Baldcypress Swamp Network (NABCSN) and the Suwannee River.
Incorporating Future Change into Current Conservation Planning: Evaluating Wetland Migration along the Gulf of Mexico under Alternative Sea-Level Rise and Urbanization Scenarios
More than half of contiguous U.S. coastal wetlands are located along the Gulf of Mexico coast. These highly-productive wetlands support many ecosystem goods and services and fish and wildlife habitat. Historically, coastal wetlands have adapted to sea-level changes via lateral and vertical movement on the landscape. As sea levels rise in the future, coastal wetlands will adapt and migrate landward...
Ecosystem Development After Wetland Restoration and Creation
Wetland restoration and creation efforts are increasingly proposed as means to compensate for wetland losses. To address the need for evaluating the development of ecosystem structure and function in restored and created wetlands, USGS compared created tidal wetlands sites to natural mangrove wetlands in Tampa Bay, Florida.
Factors Controlling Resilience and Resistance of Coastal Salt Marshes to Sudden Marsh Dieback
Sudden Marsh Dieback - SMD - has been documented for the past two decades throughout coastal areas of the United States. With these large-scale diebacks comes the loss of ecosystem functions and services. USGS scientsts use field work and greenhouse studies to investigate the factors that control the resilience and resistance of coastal salt marshes to SMD.
Integrated Modeling of Coastal Processes and Linkages to Management Applications
Coastal wetlands provide valuable ecosystem services such as wave attenuation, surge reduction, carbon sequestration, wastewater treatment, and critical habitats for endangered fish and wildlife species. However, wetland loss threatens the capacity of coastal wetlands to provide these ecosystem services.
Louisiana’s Coastwide Reference Monitoring System (CRMS)
The Coastwise Reference Monitoring System was designed to monitor the effectiveness of restoration actions at individual sites, as well as across the entire Louisiana coast.
Plant Community Dynamics in a Mangrove-to-Marsh Transition Zone
Mangroves will compete with salt marsh plants in transitional areas, and recent studies have documented the expansion of mangroves into marsh habitats. To better understand the plant community dynamics in this transition zone, USGS scientists are tracking vegeation changes over time in south Florida.
Classifying Coastal Wetland Vegetation Communities with Unsupervised Artificial Neural Networks
Wetlands are often classified by their vegetation, which can help scientists track how these landscapes change over time. USGS turns to unsupervised artificial neural networks to help guide this classification process.
