Past and Future Impacts of Sea Level Rise on Coastal Habitats and Species (FISCHS)
USGS aims to integrate biological and hydrological models to help develop management tools to deal with the projected ecological consequences of rising sea level in coastal south Florida.
Climate Change Effects on Coastal Marsh Foundation Species
Mangrove forests have migrated inland over the past few decades at many locations along the northern Gulf of Mexico coast. This expansion has been attributed to factors associated with climate change, such as increased salinity resulting from sea-level rise and longer intervals between winter freezes, which can kill cold-intolerant mangrove species.
Ecology of Greenhouse Gas Emissions from Coastal Wetlands
Wetlands have the potential to absorb large amounts of carbon dioxide via photosynthesis, and flooded soils have low oxygen levels which decrease rates of decomposition to promote the retention of soil carbon. However, the type of greenhouse gases emitted from wetlands varies by wetland type and soil condition. A suite of approaches are being used to assess fluxes of greenhouses gases, like...
Modeling Tidal Freshwater Forested Wetlands (TFFW) Habitat Changes for Land Management
As tidal freshwater forested wetlands - TFFWs - are influenced by salinty due to salt water intrusion, they may experience changes in plant community composition, growth, and productivity. Models are needed to predict vegetation community change or dieback, as well as changes in carbon sequestration and storage due to changing climate, drought, changes in freshwater discharge, elevated carbon...
Modeling Landscape-Scale Habitat Relations for Landbirds During Migration: Science Support for the Gulf Coast Joint Venture
USGS uses weather surveillance radar data and landscape-scale habitat metrics to model bird-habitat connections along the western coast of the Gulf of Mexico.
Restoration of Climate Change-Induced Retreat of Tidally Influenced Freshwater Forested Wetlands
Wetlands in river deltas - like the Mississippi River Delta Plain - may be more vulnerable to sea-level rise. Historically, coastal wetlands responded to these changes by increasing surface elevation or migrating up-slope. USGS conducts research to identify the biogeochemical influences on sediment addition in coastal wetland areas.
Salinity Intrusion Impacts from Hurricane Sandy in Tidal Freshwater Swamps, Delmarva Peninsula, Mid-Atlantic Coast, USA
When it comes to hurricanes, wind and storm surge effect vegetation differently. USGS anlyzes these differences following Hurricane Sandy to help inform management on storm mitigation and long-term planning.
Structural Equation Modeling in Support of Conservation
Understanding systems sometimes requires approaches that allow for both the discovery of the a system's structure and the estimation of its implications. Structural Equation Modeling - SEM - is one tool scientists use to better understand the complex world in which we live.
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.
Surface Elevation Vulnerability of Coastal Forested Wetlands to Sea-Level Rise
Wetlands vary in their abilities to keep up with sea-level rise; they either adjust vertically and/or move inland. USGS is working with partners around the world to measure rates of surface elevation change relative to local sea-level rise.
Mechanisms of Coastal Marsh Elevation Regulation
Sediment deposition serves an important role in the long-term maintenance of coastal marshes. USGS investigates the mechanisms of coastal marsh elevation regulation to help predict marsh sediment requirements under various sea level rise scenarios.
Assessing the Past and Potential Future Impacts of Salt Water Intrusion on Tidal Swamp Habitat along the South Atlantic Coast
Using historical aerial photogrammetry, satellite imagery, or recent vegetation mapping efforts, as well as various models, USGS investigates salt water intrusion impacts on coastal habitats along the southern Atlantic coast.
