The report describes a strategy for monitoring, modeling, and research activities to support management decisions to improve water-quality conditions in the Mississippi River Basin, reduce hypoxia in the northern Gulf of Mexico, and improve conditions for
Congress asked us (in the Energy Independence and Security Act of 2007) to figure out how to assess the effects of carbon storage, sequestration, and greenhouse gas fluxes in our ecosystems. Here's how we plan to do that.
Study of the processes by which the conversion occurred of the Palouse bioregion from perennial native grass, shrub, and forest vegetation to agriculture and the interactions between human cultures and environment.
Detailed publication on the classification system for an inventory of wetlands and deepwater habitats of the United States used to describe ecological taxa and arrange them in a system useful to resource managers.
Declines in fish and wildlife populations, water-quality issues, and changes in coastal habitats have prompted this USGS study of the region's nearshore life and environment. Includes links to data from published reports.

Research and development efforts to improve our ability to provide scientific information needed by local beach managers faced with questions about environmental quality and possible beach closure or resource usage.
Report prepared with NASA on the importance of a historical context for understanding ongoing changes in land cover and land use in North America and the effect on the environment. Site contains primarily contents of a book edited by T.D. Sisk.
This report presents geochemical data generated during mineral and environmental assessments for the Bureau of Land Management in northern Nevada, northeastern California, southeastern Oregon, and southwestern Idaho, along with metadata and maps.
Outlines tactical problems that make it difficult for beach managers to use scientific information to make beach closure and advisory decisions. Explains methodologies we are using to address those problems and better prepare local decision makers.
Overview of research in the Hawaiian Islands and Guam to gain insight into the structure of coral reefs, to provide the basis for future monitoring, and to understand the influences of natural processes and human activities on coral reef health.
