Quantitative Analysis Using Structural Equation Modeling

USGS scientists have been involved for a number of years in the development and use of Structural Equation Modeling (SEM). This methodology represents an approach to statistical modeling that focuses on the study of complex cause-effect hypotheses about the mechanisms operating in systems. SEM is increasingly used in ecological and environmental studies and this site seeks to provide educational...

Status and Trends of Emergent Wetlands in the Northern Gulf of Mexico: 1950-2010

Throughout the past century, emergent wetlands have been declining across the Gulf of Mexico. Emergent wetland ecosystems provide a plethora of resources including plant and wildlife habitat, commercial and recreational economic activity, water quality, and natural barriers against storms.

GIS Support and Spatial Analysis Support for the Louisiana Division of Administration, State Land Office

The Wetland and Aquatic Research Center (WARC) first implemented geographic information systems (GIS) in 1980 to assist in monitoring the nature and extent of wetland habitat changes. The geospatial capabilities at the Coastal Restoration Assessment Branch (CRAB), in part, grew out of that initial effort and now use GIS, remote sensing, and other computer based technologies to address a wide range...

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.
