These data and application are provided as part of USGS research on contaminants in surface waters across the United States and supported by the USGS Water Mission Area Proxies Project and the USGS Ecosystem Mission Area Environmental Health Program (Toxic Substances Hydrology).

The Species of Greatest Conservation Need (SGCN) National Database Dashboard allows access to the national aggregated list of species of greatest conservation need.

Use this visualization tool to explore and enhance your understanding of historical climatic and hydrologic conditions at select CDFW Wildlife Areas (WA) and Ecological Reserves (ER). The properties highlighted by this tool are currently serving as CDFW Sentinel Sites.

The Environmental Strontium Isotope Web Map is an interactive mapping application for displaying strontium isotope data in environmental materials (for example, waters) in geographic relation to underlying bedrock geology that drives the isotope composition. Together, these data form the basis for isotopic fingerprinting applications in geologic, hydrologic, ecologic, and forensic science.

Annual Joint Agency Commercial Imagery Evaluation (JACIE) workshops engage federal agencies, their partners, and the commercial remote sensing industry to understand the characteristics and capabilities of current and new data sources, along with the quality of data they provide. This tool allows the searching of presentations from the workshops, that started in 2001.

Emergence of avian influenza viruses with the potential to be highly pathogenic to poultry, wild birds, & humans, such as the highly pathogenic H5N1 and H7N9 cause serious concern for the global economic & public health sectors. Visual representations of model data can be effective in helping to discover how the spread of the virus is influenced by environmental & human

The EarthNow! Landsat Image Viewer displays imagery in near real-time as Landsat satellites orbit the Earth. Along with the near real-time video stream, EarthNow! also replays acquisition recordings from previous Landsat overpasses. When Landsat satellites are out of viewing range of a ground station, the most recent overpass is displayed.

Do you need to know when streamflows are low or if streams go dry? The USGS has developed a Low Flow Data and Model Discovery Table that provides an overview of available data and models with information on streamflow, including low-flow and no-flow conditions.

Quality photographs of plant species are rare on the internet, often difficult to find, and are generally copyrighted, preventing them from being used by government agencies and non-government organizations, academics and the general public.

The USGS Core Library and Data Center website enables users to search for and access digital images of rock samples primarily collected on the NNSS. Users can search for rock-sample images by specific NNSS area and site name.

The USGS-DOE Cooperative Studies and Groundwater Monitoring in Nevada website provides an interactive and easy-to-use interface to access groundwater levels, groundwater withdrawal, and water-temperature data for wells on and adjacent to the NNSS.

This web page displays groundwater-level data for selected wells monitored by the U.S. Geological Survey (USGS) in and near the Duwamish River valley, King County, Washington. These data are part of a project to better understand the geology and groundwater in and near the Duwamish River valley and how groundwater may contribute to flooding in the valley.
