Data

This data release documents seismic data collected immediately adjacent to beaver ponds and in their surrounding floodplain environments using active and passive seismic measurements at three sites. These sites are located in the University of Connecticut (UConn) Forest in Storrs, Connecticut; Fenton-Ruby Park in Willington, Connecticut; and in Gunnison County, Colorado. Horizontal-to...

This data release includes digital orthophotos acquired from a fixed-wing aircraft and field measurements of flow velocity and depth from the Tanana and Yukon Rivers, Alaska, obtained July 1 - 3, 2025. This parent data release includes links to child pages for the data sets produced during the study (see child item links below): 1. Digital orthophotos of the Tanana and Yukon Rivers in...

This metadata record describes historical flood type classifications and causal attribution data for the FEMA-funded joint U.S. Geological Survey and U.S. Army Corps of Engineers Mixed Populations Flood Frequency Project. The data listed here include classifications of historical flood peaks based on causal mechanisms determined using manual and semi-automated methods at select locations...

At present, 2026, USGS river bathymetry surveys in ScienceBase lack a consistent, standardized organizational structure which impedes discovery and use of these datasets. Standardization of USGS bathymetry surveys allows these data to be more easily identified, queried, and incorporated into any number of science applications across a range of spatial scales. This data release includes...

This data release contains results from wildfire ash samples collected in burn areas within the Russian River watershed in Sonoma County, California, as well as results produced in laboratory experiments using the ash to assess the mobility of the waterborne pathogen Cryptosporidium parvum (C. parvum) and other contaminants. Ash was collected in 2017, 2019, and 2020 following the Tubbs...

This dataset contains paired in situ and satellite-derived water surface elevation (WSE) observations compiled to evaluate the accuracy of the Surface Water and Ocean Topography (SWOT) mission water surface elevation data over rivers and lakes. In situ WSE measurements were obtained from the U.S. Geological Survey (USGS), U.S. Bureau of Reclamation (BOR), Environment and Climate Change...

This dataset contains discharge measurements derived from acoustic Doppler current profiler (ADCP) observations collected at U.S. Geological Survey (USGS) stream gage locations that are observable by the Surface Water and Ocean Topography (SWOT) satellite. ADCP measurements were compiled for the period 2015 through December 1, 2025 and paired with reach-scale median SWOT-observed water...

Overview: There are multiple systems for mapping waterbodies within the conterminous United States. Prominent among them are the "High Resolution" and "Version 2" editions of the National Hydrography Dataset Plus. The National Hydrography Dataset Plus High Resolution (NHDPlusHR, Moore and others, 2025) uses "Permanent Identifiers" to identify waterbodies, while the National Hydrography...

The US Geological Survey has collected daily streamflow data at more than 20,000 locations within the conterminous United States (CONUS). Although these data are publicly available, there is little to no information about the environmental setting under which the data were collected. Specifically, users of the data have no readily available means to determine whether the observed...

Aquatic reflectance data from Sentinel-2 satellite imagery is paired with discrete chlorophyll measurements across Oregon, Ohio, and Florida in the United States. The dataset contains a csv data file (CyAN_S2_Matched_WQ_S2.csv), a csv data dictionary file (CyAN_S2_Matched_WQ_S2_data_dictionary.csv) that describes each of the columns in the data file, and a zip file of python scripts...

The Great Basin of the Western United States hosts dozens of terminal lake systems that provide critical, abundant, and diverse ecosystems that support migratory bird species, local wildlife, and nearby communities. Water quality varies across terminal lakes in the region depending on basin geology, anthropogenic water use, climate, hydrology, and water quantity. Seasonal and long-term...

This U.S. Geological Survey (USGS) Data Release contains chemical analysis information on sediment core and oil samples collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. Following a crude-oil spill in 1979, biodegradation of petroleum hydrocarbons in the contaminated aquifer has formed distinct zones of pH and/or redox...
