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.

Concentrations of pesticides in multiple matrices to measure exposure of wild bees visiting pollinator hedgerows in northern California Concentrations of pesticides in multiple matrices to measure exposure of wild bees visiting pollinator hedgerows in northern California
To better understand the exposure of wild bees to pesticides in an agricultural landscape, samples were collected from fields in northern California. Hedgerows are known to provide habitat for wild bees, but these bees may also be exposed to pesticides from nearby agricultural fields. The study included eight hedgerow sites located in an intensively managed agricultural landscape that...
FLOwPER Database: StreamFLOw PERmanence field observations, April 2020 - Nov 2020 FLOwPER Database: StreamFLOw PERmanence field observations, April 2020 - Nov 2020
IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow, discontinuous flow, and dry) were recorded using the FLOwPER (FLOw PERmanence) field survey available in the Survey 123 and S1 mobile application. Additional information to describe the field conditions are included as part of the survey. Field observations in the FLOwPER...
Water quality, habitat, sampling methods and characteristics for grass carp in Truman Reservoir Missouri, 2017-2019 Water quality, habitat, sampling methods and characteristics for grass carp in Truman Reservoir Missouri, 2017-2019
Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from February 2017 to March 2019 to determine habitat usage in winter. Habitat parameters were measured at used and available sites to model habitat preference. In addition, tagged fish were targeted during removal attempts to determine the efficacy of...
Pesticides and pesticide transformation product data from passive samplers deployed in 15 Great Lakes tributaries, 2016 Pesticides and pesticide transformation product data from passive samplers deployed in 15 Great Lakes tributaries, 2016
This dataset includes pesticides and pesticide transformation products in 15 tributaries of the Great Lakes. Pesticides were monitored using polar organic chemical integrative samplers (POCIS) to estimate concentrations in water following standard protocols (Alvarez, 2010) in June and July 2016. POCIS extracts were analyzed for 225 chemicals (USGS National Water Quality Laboratory...
Geologic formations and mine locations for potential CO2 mineralization Geologic formations and mine locations for potential CO2 mineralization
This geodatabase contains geologic unit boundaries and asbestos site locations shown in "Carbon dioxide mineralization feasibility in the United States" (Blondes and others, 2019). Data was compiled from source material at a scale range of 1:100,000 to 1:5,000,000 and is not intended for any greater detail.
Rainfall data near the Black Hollow Debris Flow, Larimer County, Colorado 20 July 2021 Rainfall data near the Black Hollow Debris Flow, Larimer County, Colorado 20 July 2021
The data presented in this data release represent the records from a rain gage near Black Hollow, CO, a watershed that is tributary to the Cache La Poudre River. On 20 July 2021 a large rainstorm moved over the watershed and generated a large debris flow that destroyed several homes, resulting in four fatalities. The watershed had been burned prior to the rainstorm during the Cameron...
Solid bitumen and vitrinite reflectance suppression explored using hydrous pyrolysis of artificial source rock (2021) Solid bitumen and vitrinite reflectance suppression explored using hydrous pyrolysis of artificial source rock (2021)
The most commonly used parameter for thermal maturity calibration in basin modelling is mean random vitrinite reflectance (Ro). However, Ro suppression, or lower than expected Ro, has been noted in samples containing a high proportion of liptinite macerals. This has been empirically demonstrated using hydrous pyrolysis experiments of artificial source rock containing various proportions...
A finite-difference algorithm used to simulate radial diffusion, adsorption, and reactions of chlorinated ethenes in porous media A finite-difference algorithm used to simulate radial diffusion, adsorption, and reactions of chlorinated ethenes in porous media
Simulations of radial diffusion, adsorption, and reactions of volatile organic compounds (VOCs) - trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), vinyl chloride (VC), trichlorofluoroethene (TCFE) - and bromide (Br) in a porous media are conducted using rock properties identified from a mudstone aquifer in the Newark Basin, near West Trenton, New Jersey. The simulations are...
Mapped sealed and unsealed pavement and concentrations of metals, polycyclic aromatic hydrocarbons, and radionuclides for soils, pavement dust, and stream sediment for 10 urban watersheds Mapped sealed and unsealed pavement and concentrations of metals, polycyclic aromatic hydrocarbons, and radionuclides for soils, pavement dust, and stream sediment for 10 urban watersheds
These data represent a one-time synoptic survey of sampled soils, pavement dust, and stream sediment in 10 urban watersheds in three regions of the United States (Pacific Northwest, northeast, and southeast) to evaluate sources of sediment and two groups of common urban contaminants: polycyclic aromatic hydrocarbons (PAHs) and metals. Analyses of samples from six of the watersheds...
Pesticide recovery data for surface water and lab reagent samples analyzed by the USGS National Water Quality Laboratory schedule 2437, water years 2016-17. Pesticide recovery data for surface water and lab reagent samples analyzed by the USGS National Water Quality Laboratory schedule 2437, water years 2016-17.
This data release contains two tables-one table of field spike recovery data and one table of lab reagent spike recovery data-for pesticides and pesticide degradates analyzed by the USGS National Water Quality Laboratory (NWQL) schedule 2437, and associated metadata. The table of field spike recovery data includes results from paired environmental and spike samples collected by the...
Estimated Annual Agricultural Pesticide Use by Major Crop or Crop Group for States of the Conterminous United States, 1992-2019 Estimated Annual Agricultural Pesticide Use by Major Crop or Crop Group for States of the Conterminous United States, 1992-2019
This data release provides state-level estimates of annual agricultural use of pesticide compounds by major crop or crop group for states in the conterminous United States, for years 1992-2019, compiled from data used to make county-level estimates by means of methods described in Thelin and Stone (2013) and Baker and Stone (2015). The source of these data is the same as the published...
Preliminary estimated annual agricultural pesticide use for counties of the conterminous United States, 2018 Preliminary estimated annual agricultural pesticide use for counties of the conterminous United States, 2018
