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.
Site for Great Lakes Science Center, Ann Arbor, which provides information about biological resources in the Great Lakes Basin. Links to personnel, publications, data, library, facilities, research vessels, Great Lakes issues, and research.
Sulfate deposition to high-elevation areas has decreased here as a result of reductions in SO2 emissions. Nitrate deposition did not change, whereas ammonium deposition increased, particularly at sites near urban and agricultural areas.
Report on the status of the biota and ecological factors of the inland lakes of the Great Lakes Cluster Parks: Indiana Dunes, Sleeping Bear Dunes,and Pictured Rocks National Lakeshores and Isle Royale and Voyageurs National Parks. (PDF file, 321 p.)
Summary of part of the USGS interdivisional Mississippi Basin Carbon project that will study the changes in climate and the environment through carbon cycle changes recorded in lake sediments in the Upper Mississippi River Basin.
Here we study effects of climate and groundwater on surface-water levels, the hydrological effects on wetland water chemistry, and the combined effects of climate, hydrology, and water chemistry on plant and animal communities of prairie pothole wetlands.
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.
