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.

Effects of deltamethrin applications on non-target small mammal populations in South Dakota, Colorado, and Idaho, 2010-2017 Effects of deltamethrin applications on non-target small mammal populations in South Dakota, Colorado, and Idaho, 2010-2017
We trapped small mammals at two sites in Badlands National Park, Pennington County, South Dakota from 2013-2017; two sites in Larimer County, Colorado from 2010-2011; and four sites in Adams County, Idaho from 2014-2017. Each site contained at least one or more treated plots (deltamethrin dust applied to burrows or bait stations for flea control) paired with one or more non-treated plots...
Greater Sage-Grouse Nest Observations Before and After Wildfire Disturbance in Northeastern California (2007-2018) Greater Sage-Grouse Nest Observations Before and After Wildfire Disturbance in Northeastern California (2007-2018)
We monitored Greater Sage-Grouse (Centrocercus urophasianus; hereafter, Sage-Grouse) nests and various habitat characteristics at the nest locations near Susanville in northeastern California, crossing over into northwestern Nevada. We employed a before-after-control-impact (BACI) experimental design to account for spatiotemporal heterogeneity in the system and to derive estimates of...
Sedimentary geochemistry of a deepwater slope environment of southern Lake Tanganyika Sedimentary geochemistry of a deepwater slope environment of southern Lake Tanganyika
This dataset contains geochemical data (Total Inorganic Carbon, Total Organic Carbon, Total Nitrogen, δ13C of Organic Carbon, Hydrogen Index, Oxygen Index, Zirconium/Aluminum, and Magnetic Susceptibility) for sediments from one short (~1 m) core collected in 420 m of water in southern Lake Tanganyika, Tanzania.
Extreme gradient boosting machine learning models, suspended sediment, bedload, streamflow, and geospatial data, Minnesota, 2007-2019 Extreme gradient boosting machine learning models, suspended sediment, bedload, streamflow, and geospatial data, Minnesota, 2007-2019
A series of machine learning (ML) models were developed for Minnesota. The ML models were trained and tested using suspended sediment, bedload, streamflow, and geospatial data to predicted suspended sediment and bedload. Suspended sediment, bedload, and streamflow data were collected during water years 2007 through 2019. The ML models were used to improve understanding of sediment...
Anticoagulant rodenticide concentrations in blood and tissue of California condors and turkey vultures (ver. 2.0, May 2023) Anticoagulant rodenticide concentrations in blood and tissue of California condors and turkey vultures (ver. 2.0, May 2023)
The dataset includes specifics on liver tissue and blood plasma anticoagulant rodenticide concentrations measured using high-performance liquid chromatography-tandem mass spectrometry.
Legacy Geochemical Data from Hardcopy Records of Selected Past U.S. Geological Survey Projects Legacy Geochemical Data from Hardcopy Records of Selected Past U.S. Geological Survey Projects
This data release contains geochemical data from selected U.S. Geological Survey (USGS) projects from the 1960s-1980s that were previously unpublished as digital data. The objective of those projects was to describe the geology, determine petrologic and geochemical characteristics, or to evaluate the mineral resource potential of Federal Lands and adjacent study areas. These data...
