Application of the SPARROW watershed model to describe nutrient sources and transport in the Missouri River Basin [ More info] Maps and diagrams showing how the mathematical model predicts the distribution of various pollutants within a large watershed.
Assessing Groundwater Availability in the High Plains Aquifer in Parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming [ More info] Explains concepts and methods used to determine the likely future supply of usable water in this major aquifer.
Assessment of least tern and piping plover habitats on the Missouri River using remote sensing [ More info] Analysis and modeling of multispectral imagery helps to predict the suitability of sand bars for nesting of these migratory birds.
Biomarker Benchmarks: Reproductive and Endocrine Biomarkers in Largemouth Bass and Common Carp from United States Waters [ More info] Describes a national reconnaissance study of reproductive health in two species of fish across the US.
