Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for water chemistry and mercury in fish tissue to establish unbiased baseline data.
Everglades Depth Estimation Network (EDEN) for support of biological and ecological assessments [More info]
Integrated network of real-time water-level monitoring, ground-elevation modeling, and water-surface modeling that provides scientists and managers with current on-line water-depth information for the entire freshwater portion of the Greater Everglades.

PDF Examination of brine contamination risk to aquatic resources from petroleum development in the Williston Basin [More info]
Wetlands and oil wells shouldn't mix, but in some areas they do. This explains what problems may arise and how we study the effects of highly salty water produced by oil wells when it leaks into nearby wetlands and streams.
Farm ponds as critical habitats for native amphibians [More info]
Constructed farm ponds represent significant breeding, rearing, and overwintering habitat for amphibians in the Driftless Area Ecoregion of Minnesota, Wisconsin, and Iowa. Links to fact sheet, brochure, annual reports, field manual, and final report.
