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.)
New synoptic data from samples collected in the Arctic Ocean and insights into the patterns and extent of ocean acidification. This foundational geochemical information will help us to understand potential risks to Arctic resources.
Nitrate from fertilizer is degraded by microbial action in the presence of solid minerals. This helps mitigate the effect of the nitrate, but begins to diminish the solid minerals needed. Will the process be sustainable in the long term?
Overview of interdisciplinary research on the Tampa Bay estuary of the Gulf of Mexico with links to digital library, interactive mapping, reports, posters, water chemistry maps, meetings and conferences, scientist directory, and field trips.
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.
Upcoming interagency study to assess status of ecological conditions, their relationships with contaminants and nutrients, anthropogenic factors affecting these, and develop models that may predict these ecological conditions.
Homepage for the Toxic Substances Hydrology Program, which provides scientific information on contaminated sites and on human and environmental health. Links to news, topical information, investigations, meetings, publications, and photos.
Report (PDF format) on an evaluation of the potential environmental impacts of contaminated ground water from a metals refinery adjacent to the Missouri River in Omaha, Nebraska testing water and sediments for contaminants and toxicity.
