USGS Thesaurus USGS Thesaurus
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.
CWD Simulation App CWD Simulation App
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.
Public-Supply Well Water Quality Results: Inorganic Data and Trends, 1974 - 2014 (California GAMA-PBP) Public-Supply Well Water Quality Results: Inorganic Data and Trends, 1974 - 2014 (California GAMA-PBP)
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.
Story Map: Avian Influenza in the United States Story Map: Avian Influenza in the United States
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.
Anza Land Use Comparison (1934 - 2005) Anza Land Use Comparison (1934 - 2005)
Compares Anza Valley, CA land use data within the USGS study boundaries for 5 time periods between 1934 and 2005.
Anza Hydrologic Data Anza Hydrologic Data
A portal for easy access to USGS data collected during hydrogeologic research projects in Anza Valley, CA
2012 SPARROW Models for the Midwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow 2012 SPARROW Models for the Midwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
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.
2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow 2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
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.
