The Bull Trout Population Dynamics Simulation Tool visualizes and provides estimates of bull trout populations in subwatersheds (HUC 12).

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 Central Valley Hydrologic Model version 2 (CVHM2) is an integrated surface–subsurface hydrologic model, representing the major components of the hydrologic system of California’s Central Valley. This new decision support tool is useful for testing water management strategies in California's Central Valley.

This Interactive Atlas of Critical Minerals shows you where critical minerals are produced. Discover which countries produce critical minerals, what percent of the world production they are responsible for, and details on what each mineral is used for.

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.

This interactive web application allows you to explore, filter, and download subsets of the Energy Geochemistry Database (EGDB). The EGDB contains analytical data for samples collected by the Energy Resources Program (ERP) to develop an understanding of the physical and geochemical processes responsible for hydrocarbon formation.

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.

This app displays historical total chlorophyll observations at U.S. Geological Survey (USGS) gaging stations, forecasts from the USGS models currently submitted to the Ecological Forecasting Initiative (EFI)-USGS River Chlorophyll Forecasting Challenge, and forecasted driver data used to create the models in a user-friendly interface.

Geoheritage lies at the intersection of science and society and is a term applied to significant or unique geologic features representing the values that we as a Nation place on them. These geologic features are recognized for their scientific, educational, cultural, economic, and aesthetic values.

The Geologic Hydrogen Prospectivity Map Explorer hosts various geologic and geophysical data layers in support of the U.S. Geological Survey’s initiative to map the potential of geologic hydrogen within the conterminous U.S. This first-ever Hydrogen Map Explorer contains 19 input maps and 7 integrated maps that highlight prospective areas for naturally occurring hydrogen across the country.

A Data Visualization and Decision Support Tool for Building and Conserving Ecological Resilience through Results-Oriented Grazing

This is a tool to help figure out where groundwater is going.
