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.

Mercury Condition Index Tool Mercury Condition Index Tool
The Mercury Condition Index Tool uses existing data of mercury concentrations in invertebrates, fish, and birds within national parks to estimate a park level Condition Index (and associated uncertainty) for mercury, based on its potential risk to fish and wildlife health. The tool employs a series of logic steps to convert provided data into standardized units, based upon both basic
Modelled functional group vegetation cover from 2016 to 2020 on the Soda Wildfire Modelled functional group vegetation cover from 2016 to 2020 on the Soda Wildfire
These rasters represent plant cover during each of the first five growing seasons after fire in the area burned in the 2015 Soda wildfire. Specifically included cover layers are annual herbaceous, perennial herbaceous, shrub, exotic annual grass, and bareground. Training data for each year was collected via grid-point intercept monitoring between April and August. Empirical Bayesian...
Demographic model inputs and code, catchment area population estimates, and counterfactual (CIU) estimates for population growth for 23 focal bird species. Demographic model inputs and code, catchment area population estimates, and counterfactual (CIU) estimates for population growth for 23 focal bird species.
Renewable energy production can kill birds, but little is known about how it affects avian populations. We assessed vulnerability of populations for 23 priority bird species killed at wind and solar facilities in California, USA.
Genomic variation in the genus Pimephales: raw sequence data and single-nucleotide polymorphisms Genomic variation in the genus Pimephales: raw sequence data and single-nucleotide polymorphisms
The fathead minnow (Pimephales promelas) is a key model of vertebrate toxicity. Standardized tests of toxicity in fathead minnow have been developed to support regulatory science, and much is known about the response of the species to various environmental pollutants. However, there is little data on genetic variation within the species, despite the potential influence of genetic...
Harmful Algal Bloom Toxins in Seabirds, Forage Fish, and Marine Invertebrates Across Alaska Harmful Algal Bloom Toxins in Seabirds, Forage Fish, and Marine Invertebrates Across Alaska
These data include results from screening tissues of marine organisms for the presence of harmful algal bloom (HAB) toxins: saxitoxin and its related congeners (STX) and domoic acid (DA). Samples collected by USGS or submitted to our laboratory by partners or other stakeholders are screened using commercially available enzyme linked immunosorbent assays (ELISA). A subset of samples...
Demographic and potential biological removal models identify raptor species sensitive to current and future wind energy Demographic and potential biological removal models identify raptor species sensitive to current and future wind energy
A central challenge in applied ecology is understanding the effect of anthropogenic fatalities on wildlife populations and predicting which populations may be particularly vulnerable and in greatest need of management attention. We used 3 approaches to investigate potential effects of fatalities from collisions with wind turbines on 14 raptor species for both current (106 GW) and...
Interactive PHREEQ-N-AMDTreat+REYs water-quality modeling tools to evaluate potential attenuation of rare-earth elements and associated dissolved constituents by aqueous-solid equilibrium processes (software download) Interactive PHREEQ-N-AMDTreat+REYs water-quality modeling tools to evaluate potential attenuation of rare-earth elements and associated dissolved constituents by aqueous-solid equilibrium processes (software download)
Software utilizing PHREEQC with user interface. The PHREEQ-N-AMDTreat+REYs geochemical modeling tools have the fundamental capability to simulate and predict key reactions related to the treatment of acid mine drainage and the formation of treatment solids, including the adsorption of rare-earth elements plus yttrium (REYs) onto hydrous iron, aluminum, and manganese oxides. These new...
Wildland-urban interface maps for the conterminous U.S. based on 125 million building locations Wildland-urban interface maps for the conterminous U.S. based on 125 million building locations
The wildland-urban interface (WUI) is the area where urban development occurs in close proximity to wildland vegetation. WUI maps for the conterminous U.S. were generated using building point locations, offering higher spatial resolution compared to previously developed WUI maps based on U.S. Census Bureau housing density data (Radeloff et al., 2017). Building point locations were...
Precomputed Percent Forested-Area Rasters Derived from NLCD 2016 in Support of the StreamStats Fire-Hydrology Application, Conterminous United States Precomputed Percent Forested-Area Rasters Derived from NLCD 2016 in Support of the StreamStats Fire-Hydrology Application, Conterminous United States
The U.S. Geological Survey (USGS) computed rasters of pre-solved values for the watersheds draining to the pixel delineation point representing the watershed's percent forested land cover from the National Land Cover Dataset (NLCD) 2016 data (land cover values 41-43). These values, which cover the conterminous United States at a scale of 30m pixel size, will be served in the National...
Historical groundwater and produced water chemistry data compiled for the Placerita and Newhall Oil Fields, Los Angeles County, southern California Historical groundwater and produced water chemistry data compiled for the Placerita and Newhall Oil Fields, Los Angeles County, southern California
This digital dataset includes 580 samples from 12 groundwater wells and 45 samples of produced water from 38 sites (including 17 wells) located within 3 miles of the Placerita and Newhall Oil Fields in Los Angeles County, southern California. Historical geochemistry data were compiled from multiple data sources for selected water-quality indicators, major and minor ions, nutrients, trace...
Literature compilation of paleocurrent data from the Late Paleozoic Ouachita orogen, Oklahoma-Arkansas, U.S.A. Literature compilation of paleocurrent data from the Late Paleozoic Ouachita orogen, Oklahoma-Arkansas, U.S.A.
This digital geospatial compilation gathered paleoflow indicators from current-formed sedimentary structures throughout the Paleozoic Ozark uplift, Arkoma foreland basin, and Ouachita fold-thrust-belt of eastern Oklahoma and western Arkansas from existing publications. This dataset consists of unidirectional and bidirectional paleocurrents observed from a variety of bedform types...
