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.

Observed and predicted thermal exposure data, and associated land cover characteristics, of commuting locations in Denver Colorado Observed and predicted thermal exposure data, and associated land cover characteristics, of commuting locations in Denver Colorado
Examining urban thermal environments has become a critical area of research spanning epidemiology, urban planning, and ecology. While traditional metrics like air temperature (Tair) and satellite-derived surface temperature (SD-LST) dominate urban heat studies, these measures often fail to reflect how people actually experience thermal exposure intensity. More human-oriented metrics...
Model archive summary for suspended-sediment concentration at station 11516530, Klamath River below Iron Gate Dam, California, October 2023 to December 2024 Model archive summary for suspended-sediment concentration at station 11516530, Klamath River below Iron Gate Dam, California, October 2023 to December 2024
This model archive summary (MAS) and associated model calibration data describes a surrogate model used to compute suspended-sediment concentrations (SSC) at USGS streamgage 11516530 from October 2023 to December 2024. The period of analysis computes SSC during the drawdown and removals of three dams upstream of the streamgage and represents novel suspended-sediment transport conditions...
Exotic Annual Grass (EAG) Phenology estimates for Western U.S. Rangelands based on 30-m HLS for 2017 - 2025 Exotic Annual Grass (EAG) Phenology estimates for Western U.S. Rangelands based on 30-m HLS for 2017 - 2025
Monitoring plant life stages (i.e., phenology) is pertinent to land management as phenological dynamics reflect the vegetation response to changes in weather and disturbance and to changes in vegetation composition. Exotic Annual Grass (EAG) invasion has threatened habitats and economies across the western U.S. The phenology of EAG species, such as cheatgrass, differs from native...
Mineral, mineral chemistry, and geochronology data for regolith samples, Mount Weld, Western Australia Mineral, mineral chemistry, and geochronology data for regolith samples, Mount Weld, Western Australia
This U.S. Geological Survey (USGS) data release contains analytical data from a suite of mineral samples collected from the Mount Weld carbonatite complex, western Australia. This complex hosts the largest producing rare earth element (REE) mine outside of China. The REEs are mined from the weathered material, a laterite, derived from an underlying carbonatite. Samples were collected...
Detection of Four Runs of Telemetry Tagged Juvenile Chinook Salmon in the Sacramento River and Georgiana Slough and Associated Flow Data from 2009 to 2022 Detection of Four Runs of Telemetry Tagged Juvenile Chinook Salmon in the Sacramento River and Georgiana Slough and Associated Flow Data from 2009 to 2022
To assess the influence of run type and flow on the routing of juvenile Chinook salmon at the Georgiana Slough junction, we assembled a dataset of fish telemetry detections and flow data spanning a 12-year period. Fish detection data were obtained from the National Marine Fisheries Service’s Environmental Research Division’s Data Access Program (ERDDAP, 2023) and represent all four...
Viral haemorrhagic septicemia virus and viral erythrocitic necrosis virus prevalence and intensity in the field and laboratory experiments to measure interdependencies between the pathogens Viral haemorrhagic septicemia virus and viral erythrocitic necrosis virus prevalence and intensity in the field and laboratory experiments to measure interdependencies between the pathogens
From 2019 to 2021, sixty age 0 herring were collected and tested for infection with viral haemorrhagic septicemia virus and viral erythrocitic necrosis virus from Port Angeles Harbor in WA, USA. This dataset describes the prevalence and intensity of infection with both pathogens. Then a series of laboratory experiments were conducted to determine how the epizootics of the two pathogens...

This dataset includes major-, minor-, and trace-element analyses by electron probe microanalysis (EPMA) and trace-element analyses by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of olivine, plagioclase, clinopyroxene, and orthopyroxene minerals from scoria and lava samples from the Kamakaiʻa Hills of the Southwest Rift Zone of Kīlauea volcano, Island of...
Exposure, sensitivity, and vulnerability to drivers of ecological change for Ecological Site Groups of southeastern Utah, USA Exposure, sensitivity, and vulnerability to drivers of ecological change for Ecological Site Groups of southeastern Utah, USA
These data were compiled to estimate vulnerability to multiple drivers of ecological change at the landscape scale in southeastern Utah based on sensitivity to state change and spatial exposure of Ecological Site Groups (ESGs) developed by Nauman et al. (2022). The objectives of our study were to: (1) estimate sensitivity of ESGs to aridification, livestock grazing, invasive species...
