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.

Laboratory optical measurements to assess long-term changes in water-extractable soil organic matter, U.S. Great Plains Laboratory optical measurements to assess long-term changes in water-extractable soil organic matter, U.S. Great Plains
Carbon (C) and nitrogen (N) extracted from soil with water are associated with available plant nutrients and microbial activity, but information about how C and N have changed over time in the U.S. Great Plains is sparse. Optical measurements of absorbance and fluorescence were used to compare dissolved organic matter (DOM) extracted from historic (1947) and contemporary (2018) soil...
Georgia active streamgages with attributes and their upstream drainage basins, 2024 Georgia active streamgages with attributes and their upstream drainage basins, 2024
In cooperation with the Georgia Department of Transportation, the U.S. Geological Survey (USGS) has prepared geospatial layers representing the locations of USGS streamgages, other weather monitoring locations, and upstream drainage basins of streamgages in the State of Georgia. These layers also include streamgages in nearby states which directly measure waters within Georgia. The...
Surface Water Index of Permanence (SWIPe) for the upper Missouri River basin, 1989-2021 Surface Water Index of Permanence (SWIPe) for the upper Missouri River basin, 1989-2021
With the Surface-Water Index of Permanence (SWIPe) we provide a standardized metric for describing one- to five-year anomalies of the annual minimum surface-water extent of streams and wetlands for multiple spatial scales including basin (4-digit hydrologic unit codes [HUCs]) to subwatersheds (12-digit HUCs). Drier conditions are represented by negative SWIPE values that range from 0 to...
Records of vessel-Florida manatee collision outcomes and empirical boat speeds in Florida waters, 1978 - 2014 Records of vessel-Florida manatee collision outcomes and empirical boat speeds in Florida waters, 1978 - 2014
The dataset contains observational records detailing collisions between boats and Florida manatees (Trichechus manatus latirostris). Data include boat speeds, collision locations, and manatee injury outcomes, and are intended for ecological analysis and conservation purposes.
Shoreline Change of Western Long Island, New York from Satellite Derived Shorelines Shoreline Change of Western Long Island, New York from Satellite Derived Shorelines
This data release contains tidally corrected shoreline positions for three sites of western Long Island, NY (Rockaway Peninsula, Long Beach, and Jones Beach Island). Both CSV files of tidally corrected shorelines and GeoJSON files of the region of interests (ROIs), transects, and reference shorelines are provided within respective zip files. Both file types are derived from CoastSeg v1.1...
2021 Potomac River Phase II Topobathymetric Lidar Validation - USGS Field Survey Data 2021 Potomac River Phase II Topobathymetric Lidar Validation - USGS Field Survey Data
U.S. Geological Survey (USGS) scientists conducted field data collection efforts between September 30th and October 9th, 2021 over a large stretch of the Potomac River in Maryland and West Virginia using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data that was collected
