Data Analysis Tools

USGS, as part of the National Wastewater Surveillance System, designed and implemented high-frequency sampling of wastewater across six states throughout September 2021, to support tracking of potential increases in COVID-19 infections in communities. COVID-19 viral loads were determined for each sample with the goal of delivering results to the CDC within three days of sampling.

USGS Scientists published a StoryMap showing projected changes in land use, flooded area, and wildlife habitat in California’s Central Valley for five scenarios of future climate and water management.

USGS scientists published a storymap explaining the impacts of sea-level rise on liquefaction severity around the San Francisco Bay Area, California for the magnitude 7.0 ‘HayWired’ earthquake scenario along the Hayward Fault.

Real-time computed concentrations of water-quality constituents such as suspended sediment and fecal coliform bacteria are calculated using ordinary least squares regression models. The results of these models, along with direct water-quality measurements, can be viewed here as time-series graphs, or downloaded as tabular data.

Species observations for the United States and Territories.

The Test Site Catalog contains information about worldwide radiometric, geometric, and spatial calibration sites used for post launch characterization and calibration of Earth observation sensors.

This application provides a set of interactive data visualization tools to explore datasets generated by USGS researchers for the RESTORE project. The purpose of this tool is to help stakeholders, decision makers and other interested users access these datasets and develop a better understanding of spatial and temporal streamflow patterns in the Lower Mississippi-Gulf Region.

The USGS National Climate Change Viewer (NCCV) is a web application for visualizing climate change projections across the conterminous United States. Users can visualize projected changes in climate and water balance by state, county or USGS Hydrologic Units.

The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

Neural networks are powerful deep learning models that help us make accurate environmental predictions. This data visualization describes how to train an artificial neural network, and how the USGS uses them to make physically-realistic predictions with less data.

This mapper identifies USGS Federal Priority Streamgages (FPS). FPS are monitoring stations that track the amount of water in streams and rivers across the Nation to meet long-term federal information needs. They are strategically positioned to serve as a backbone for the larger National Streamflow Network that is operated in cooperation with over 1,200 federal, state, tribal, and local agencies.

A majority of the water in the western U.S. comes from snowmelt, but changes in the timing, magnitude, and duration of snowmelt can alter water availability downstream. This data visualization story explores what changing snowmelt means for water in the West, and how new USGS efforts can advance snow science by modeling snowpack and snowmelt dynamics and linking these results to streamflow.
