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...
Macroclimatic Controls of Coastal Wetland Ecosystem Structure and Function
At the global-scale, macroclimatic drivers govern ecosystem structure and function in tidal saline wetlands (e.g., salt marshes, mangrove forests, salt flats). However, global reviews and models for these ecosystems typically do not directly include climatic drivers. The objective of this research is to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure...
Geographical Trends in Ecosystem Function and Biodiversity of Wetlands as a Surrogate for Climate Change
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.
GIS and Custom Application Support for the Gulf Coast Ecosystem Restoration Council

RESTORE Science: Inventory of Gulf of Mexico Ecosystem Indicators Using an Ecological Resilience Framework
To effectively manage an ecosystem, resource managers need a way to evaluate its health and ability to function. Metrics that indicate ecosystem condition - or indicators - can be used to help determine how well management strategies work.
Transboundary Aquifer Assessment Program (TAAP)
Transboundary aquifers are an essential source of water for United States – Mexico border communities. Declining water levels, deteriorating water quality, and increasing use of groundwater resources on both sides of the border raise concerns about the long-term availability of this supply.
The U.S. – Mexico Transboundary Aquifer Assessment Act (Public Law 109-448) of 2006 was enacted...
NAWQA High Plains Regional Groundwater Study

Texas Source-Water Susceptibility Assessment
In the State of Texas, both surface water (streams, canals, and reservoirs) and ground water are used as sources of public water supply (PWS). Surface water sources of public water supply are susceptible to contamination from point and nonpoint sources. To help protect sources of drinking water and to help develop protective yet cost-effective and risk-mitigated monitoring strategies, the...
