Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Fuels Data for the 2000 Jasper Fire in the Black Hills of South Dakota, Collected in 2023-2025 (ver. 2.0 January 2026) Fuels Data for the 2000 Jasper Fire in the Black Hills of South Dakota, Collected in 2023-2025 (ver. 2.0 January 2026)
Post-fire vegetation structure and fuel data are needed to understand how an area recovers over time. To address this need, data were collected within the perimeter of the 2000 Jasper Fire near Custer, SD, on 73 plots co-located with plots previously established by scientists to assess burn severity. Vegetation structure data were collected at these plots during two periods: July 11–17...
Horizontal-to-Vertical Spectral Ratio (HVSR) Measurements and Depth to Bedrock Estimates along the Salmon River Corridor from the Adirondack Foothills to the St. Lawrence Lowlands, Franklin County, New York, 2018-2023 Horizontal-to-Vertical Spectral Ratio (HVSR) Measurements and Depth to Bedrock Estimates along the Salmon River Corridor from the Adirondack Foothills to the St. Lawrence Lowlands, Franklin County, New York, 2018-2023
This data release contains 22 horizontal-to-vertical spectral ratio (HVSR) seismic measurements at 21 sites in Franklin County, New York. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective technique for estimating the thickness of unconsolidated sediments over bedrock. This technique uses a single broadband three...
Horizontal-to-Vertical Spectral Ratio (HVSR) Measurements and Depth-to-Bedrock Estimates in the Cattaraugus Creek Valley between Springville and Arcade in Erie, Cattaraugus, and Wyoming Counties, New York, 2019-2023 Horizontal-to-Vertical Spectral Ratio (HVSR) Measurements and Depth-to-Bedrock Estimates in the Cattaraugus Creek Valley between Springville and Arcade in Erie, Cattaraugus, and Wyoming Counties, New York, 2019-2023
This data release contains 43 horizontal-to-vertical spectral ratio (HVSR) seismic measurements in Erie, Cattaraugus, and Wyoming Counties, New York collected between 2019 and 2023, in cooperation with the New York State Department of Environmental Conservation. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective...
Passive acoustic data collected using stationary hydrophones on rivers in the Willamette River Basin, Oregon Passive acoustic data collected using stationary hydrophones on rivers in the Willamette River Basin, Oregon
Underwater passive acoustic monitoring was conducted at multiple sites on rivers in the Willamette River Basin, Oregon. Hydrophones were used to record the sound associated with coarse river-bed sediment (bedload) movement. Bedload supply and transport are key factors determining channel morphology in gravel-bed rivers and can affect reach-scale conditions such as aggradation and...
CORHIST: 200 years of historical coregonine spawning in the Great Lakes CORHIST: 200 years of historical coregonine spawning in the Great Lakes
The dataset presented here, a historical coregonine spawning database, or CORHIST for short, is the result of several years of coordinated research in archives, libraries, and field stations, to track down evidence of spawning locations for the Coregoninae sub-family of ciscoes and whitefishes in the Great Lakes of North America and their tributaries. Our objective was to accurately...
SnowModel Simulations for the 2022–23 Water Years, near Coal Creek, San Juan Mountains, Colorado, USA SnowModel Simulations for the 2022–23 Water Years, near Coal Creek, San Juan Mountains, Colorado, USA
This data release contains SnowModel snow evolution simulation output from water years 2022 to 2023 (October 1, 2021, through September 30, 2023) on a 100-meter (m) geospatial grid for a 3 kilometer (km) × 2 km model domain near Coal Creek off Coal Bank Pass in the San Juan Mountains in southwest Colorado, USA. The three quantities simulated for this release were snow water equivalent...
