Findings from US Geological Survey studies on sources, occurrence, effects and risk of contaminants throughout the Chesapeake Bay Watershed.

A summary of the earthquake sequence in the Alaska Peninsula during 2020 and 2021. On 29 July 2021, a magnitude (M) 8.2 earthquake occurred southeast of Perryville, Alaska, (south of the Alaska Peninsula). This event was preceded in 2020 by two nearby earthquakes. The first was a M7.8 earthquake (22 July 2020), followed three months later by a M7.6 earthquake (19 October 2020).

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts, is one of three centers serving the mission of the USGS Coastal/Marine Hazards and Resources Program (CMHRP). Since its authorization by Congress in 1962, the CMHRP has served as the primary Federal program for marine geology and physical science research.

The Coconino aquifer (C aquifer) supplies water to northeastern Arizona. Proposed increases in groundwater withdrawal to meet population demands, coupled with ongoing drought conditions, increase the potential for water-level changes in the aquifer. The USGS monitors groundwater and surface-water conditions in northeastern Arizona.

An interactive geonarrative with a plain-language summary of the four 2020 Intermountain West (IMW) earthquakes that occurred in Utah, Idaho, Nevada, and California.

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.

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.

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..
