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.

Geospatial data and hydraulic-model archive for evaluation of flood-inundation maps developed for a reach of the Little Blue River at Grandview, Missouri Geospatial data and hydraulic-model archive for evaluation of flood-inundation maps developed for a reach of the Little Blue River at Grandview, Missouri
The U.S. Geological Survey (USGS) in cooperation with the city of Grandview, Missouri, assessed flooding of the Little Blue River at Grandview resulting from varying precipitation magnitudes and durations, and expected land cover changes. The precipitation scenarios were used to develop a library of flood-inundation maps that included a 3.5-mile reach of the Little Blue River and...
Geochemistry time series and growth parameters from Tutuila, American Samoa coral record (ver. 2.0, June 2021) Geochemistry time series and growth parameters from Tutuila, American Samoa coral record (ver. 2.0, June 2021)
Geochemical analysis (including radiocarbon, stable carbon isotope, and elemental composition) and growth parameters (including calcification rate, density, and extension information) were measured from a coral core collected from a reef off the southern side of Tutuila, American Samoa. The core was collected near Matautuloa Point on 8 April 2012 in collaboration with the Ecosystem...
Coral geochemistry time series from Kahekili, west Maui Coral geochemistry time series from Kahekili, west Maui
Geochemical analysis (including stable boron, boron:calcium ratio, and carbon and oxygen isotopes) were measured from coral cores collected in July 2013 from the shallow reef at Kahekili in Kaanapali, west Maui, Hawaii from scleractinian Porites lobata.
Tracking the growth of Ophidiomyces ophidiicola over time in natural and sterile soils using quantitative PCR Tracking the growth of Ophidiomyces ophidiicola over time in natural and sterile soils using quantitative PCR
Wildlife diseases pose an ever-growing threat to global biodiversity. Understanding how wildlife pathogens are distributed in the environment and the ability of pathogens to form environmental reservoirs is critical to understanding and predicting disease dynamics within host populations. Snake fungal disease (SFD) is an emerging conservation threat to North American snake populations...
Compilation of estuarine salinity data for sites used in RESTORE Streamflow alteration assessments (ver. 2.0, May 2021) Compilation of estuarine salinity data for sites used in RESTORE Streamflow alteration assessments (ver. 2.0, May 2021)
The presence of salinity in shallow waters influences living resources and habitats within Gulf of Mexico estuaries. The salinity gradient is widely recognized as foundational in maintaining biological diversity and productivity of estuaries. A clear understanding of the factors controlling salinity and its variability in estuarine surface waters is essential for proper stewardship and...
Time Series of Structure-from-Motion Products-Orthomosaics, Digital Elevation Models and Point Clouds: Little Dauphin Island and Pelican Island, Alabama, September 2018-April 2019 Time Series of Structure-from-Motion Products-Orthomosaics, Digital Elevation Models and Point Clouds: Little Dauphin Island and Pelican Island, Alabama, September 2018-April 2019
Barrier islands are dynamic environments that are gradually shaped by currents, waves, and tides under quiescent conditions, yet can evolve in the time scale of hours to days during hurricanes and other extreme storms. Small unmanned aircraft systems (sUAS) allow the opportunity for collecting topographic data for monitoring purposes, with a temporal resolution that is well-suited for...
