Ecological Processes

Storm surge waves and tides of hurricanes have the propensity to wash up marsh detritus of dead reeds and leaf debris along with plastic trash and lumber, commonly referred to as wrack, from overwashed beaches, marshes, forests, streets, and lawns.

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.

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.

This study analyzes changes in the extent of land in coastal Louisiana by using an average of 81 datasets (multiple dates of satellite data from 1973 to 2014) for summarizing land and water areas.

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.

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...

Extreme drought and temperature in the southeastern United States may become more frequent in the future, and any extreme shifts in climate condition are likely to have effects on wetland ecosystem function. USGS research predicts the effects of climate change by shifts in function and biodiversity across existing climate gradients in baldcypress swamps.

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.

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.

The scientists at the Wetland and Aquatic Science Center (WARC) have provided coastal restoration project managers and decision makers with GIS planning, database and custom application capacity since 1992. The scope and complexity of this support has increased over the years and has resulted in the development of a comprehensive geospatial and advanced application teams that provide decision...

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.

In light of the increase in hurricane frequency and intensity, there is concern about the resilience and sustainability of coastal wetlands. Models can be used to investigatethe impacts of future hurricanes on wetland morphology along the northeast coasts in areas like Jamaica Bay, New York, an area impacted by Hurricane Sandy.
