The Earth's crust [More info]
Information on the Earth's crust with a contour map of the thickness plus links to a global crustal database, a global crustal model - CRUST 5.1, and regional crustal models.
PDF The Midwest Stream Quality Assessment [More info]
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.
PDF U.S. Geological Survey methodology development for ecological carbon assessment and monitoring [More info]
To assess the effectiveness of ecological carbon sequestration, we plan to define ecosystem reporting units, model baseline and potential carbon sequestration, develop spatial models that simulate ecosystems, and integrate remote sensing data.
PDF Understanding beach health throughout the Great Lakes-Entering a new era of investigations [More info]
People who manage recreational areas need better, more timely estimates of the likelihood that the beach and lake waters will be hazardous to human health, and which factors cause those hazards.
Using geochemical and statistical tools to identify irrigated areas that might contain high selenium concentrations in surface water [More info]
Program using pattern recognition analysis and classification models to determine areas of irrigated land with concentrations of selenium.
PDF Using models for the optimization of hydrologic monitoring [More info]
Usually we choose to put water monitoring stations in places where we have no data already. But it's more efficient to place stations so that they help to reduce uncertainty in the results of modeling. This analysis shows how to choose.
Visualization of flow alternatives, Lower Missouri River [More info]
This report presents a visual, statistical presentation of five modeled flow-management alternatives and two reference alternatives for four selected sites on the Lower Missouri to aid in decision making for flow management of the river.
Visualizing NetCDF Files by Using the EverVIEW Data Viewer [More info]
Scientific software providing graphical displays of data in NetCDF format as spatial overlays on a three-dimensional globe and views of grid-cell values in tabular form.
