This formal USGS Thesaurus conforming to ANSI/NISO Z39.19, with rigid adherence to the hierarchical (BT, NT) term relationships, generic non-hierarchical (RT) relationships, and lead-in term relationships linking non-preferred terms to descriptors either singly (UF) or in a compound USE- WITH relationship.

Uranium is a radioactive element (radionuclide) that occurs naturally in rock, soil, and water – usually in low concentrations. Radionuclides are unstable atoms with excess energy and as radionuclides decay, they emit radiation. The uranium decay sequence also includes other radionuclides of concern such as radium and radon (DeSimone and others, 2014).

Chronic wasting disease (CWD) is a fatal disease of deer, elk, and moose transmitted through direct contact and via environmental contamination. This software provide tools to simulate CWD and harvest management scenarios. These models were developed by the U.S. Geological Survey (USGS) in collaboration with Montana Fish, Wildlife, and Parks.

The New England WSC geonarrative explores the availability of water-quality data collected by the Cape Cod National Seashore and U.S. Geological Survey in support of the Herring River restoration project. It highlights the development of the monitoring program since the 1980s and the recent publication of Cape Cod National Seashore data in a U.S. Geological Survey data release.

A geonarrative summary of the USGS report that provides a broad perspective on California’s exposure to volcanic hazards. By integrating volcanic hazard information with geospatial data on populations, infrastructure, and resources, the results provide estimates of impacts to people and our environment if an eruption were to occur.

The GAMA-PBP Public-Supply Well Results data viewer allows the user to visualize and download California water-quality data and trends for1974 - 2014. Groundwater-quality data for 38 inorganic constituents are captured and can be downloaded for individual sites or by grid cell. 

Developed by Lower Mississippi-Gulf scientists, these visual flood warning maps empower citizens, federal, state, and local partners to understand flood risks in Louisiana.

This story map explores the role USGS scientists play in understanding the risks presented by avian influenza, and how their work is being used to predict areas of transmission risk.

Compares Anza Valley, CA land use data within the USGS study boundaries for 5 time periods between 1934 and 2005.

A portal for easy access to USGS data collected during hydrogeologic research projects in Anza Valley, CA

This geonarrative features research used to predict how Fire Island beaches change in response to storms and how they may subsequently recover in the year following a storm event.

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.
