San Francisco Bay-Delta Water Quality, Nutrient, and Phytoplankton Mapping, 2018-2020-2021-2022-2023-2024 Comparison

A geonarrative introducing an integrated approach to improve efficiency and delivery of actionable USGS drought science using advanced information technology.

Learn about how the Climate Adaptation Science Centers have been exploring the topic of ecological drought across the country.

The Fish and Climate Change Database (FiCli) is a comprehensive resource of climate change effects on inland fishes globally.

A geonarrative highlighting the Climate Adaptation Science Center's science, partnerships, and capacity building activities from Fiscal Year 2020.

During major storms or other short-term events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based 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.

The USGS Mississippi Alluvial Plain (MAP) Regional Water Availability Study began airborne geophysical mapping to obtain high-resolution information about the hydrogeologic structure and properties of the aquifer. This geonarrative showcases the geophysical data collected in this effort and provides a three-dimensional view into the Mississippi Alluvial Plain subsurface.

A multi-agency team is mapping uncharted waters and exploring deep-sea ecosystems off the west coast of the United States. Oceans cover 71% of the Earth's surface, yet little is known about these vast underwater worlds. Less than 20% have been explored. A global initiative seeks to change that, by pledging to complete detailed mapping of one-hundred percent of the seafloor by the year 2030..

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.

Water quality is essential for understanding water availability by providing insights into the drivers of change and possible availability constraints. Using data from eight monitoring organizations including the USGS, the Multisource Water-Quality Trends in the Delaware River Basin mapper shows changing water-quality trends from 2008-2018 in rivers and streams across the Delaware River Basin.
