View recent and historical chloride and specific conductance data for active water-quality monitoring stations on streams in Connecticut, Massachusetts, and Rhode Island.

The USGS, the science bureau of the Department of the Interior, conducts wildlife disease surveillance and research to support management of affected species and their habitats. Here you will find information on USGS science addressing Chronic Wasting Disease across the Nation.

Geonarrative that includes summaries of research highlights from the USGS Climate Research & Development Program during 2020.

Alaska's north coast has been home to indigenous communities for centuries. Changing coastlines threaten important infrastructure and historic sites that support indigenous communities. Changing coastlines also can potentially reduce habitat for Arctic wildlife, such as polar bears, shorebirds, and walruses.

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

Since 1969, USGS has collected water-quality data along the deep-channel longitudinal axis of the San Francisco Bay-Delta system at 37 fixed locations spaced 3-6 kilometers apart. The Water Quality of San Francisco Bay Data Query provides access to the entire dataset.

People have been recording seismic activity for centuries. To assemble a detailed earthquake history of an area and understand how faults may behave in the future, however, scientists need to go further back in time—from several hundred to many thousands of years ago.

This geonarrative (Esri Story Map) takes you on a virtual tour of 1906 and 1969 earthquake damage in Santa Rosa, shows examples of buildings that have been retrofitted to protect against future earthquake shaking, and highlights locations where faulting from large earthquakes and slow fault slip (creep) is expressed at the ground surface.

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

This interactive map depicts the likelihood of debris-flow generation and estimates of flow magnitude in locations where debris flows initiate. The models do not predict downstream impacts, potential debris-flow runout paths, and the areal extent of debris-flow or flood inundation.

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

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..
