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.

Code for analysis of polar bear maternal den abundance and distribution in four regions of northern Alaska and Canada within the Southern Beaufort Sea subpopulation boundary (1982-2015) Code for analysis of polar bear maternal den abundance and distribution in four regions of northern Alaska and Canada within the Southern Beaufort Sea subpopulation boundary (1982-2015)
We have archived the derived data files and R/JAGS code for our analysis as a U.S. Geological Survey data release (link ). The code is divided into three R scripts: 1) pbdens_landdens_JWM.r contains R code for fitting hierarchical Bayesian models of polar bear maternal den abundance and distribution for the Southern Beaufort Sea (SBS) subpopulation, 1982-2015. This script requires the...
Digital data of the previously published geologic map showing configuration of the bedrock, North Platte, 1 degree x 2 degrees quadrangle, Nebraska Digital data of the previously published geologic map showing configuration of the bedrock, North Platte, 1 degree x 2 degrees quadrangle, Nebraska
This digital data release contains previously published geologic data compiled for the North Platte 250k quadrangle, a region in west-central Nebraska largely covered by Quaternary deposits, with exposures of Tertiary Ogallala and Brule formations in the southern portion of the study area. Geologic map data were compiled for the purposes of digitizing the geologic data as part of the...
USGS National and Global Oil and Gas Assessment Project-Montana Thrust Belt Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project-Montana Thrust Belt Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered gas resources in the Montana Thrust Belt province in Montana. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level...
Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios
Global downscaled projections are now some of the most widely used climate datasets in the world, however, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we apply steps to improve the utility of two such global datasets (CHELSA and WorldClim2) to provide credible climate scenarios for climate change impact studies in...
Cone penetrometer and elevation measurement data of coastal wetland plant states for resilience quantification, Louisiana, USA (2019) Cone penetrometer and elevation measurement data of coastal wetland plant states for resilience quantification, Louisiana, USA (2019)
These datasets provide: 1) field-collected geotechnical data, and 2) Real-Time-Kinematic GPS elevation data for coastal salt marsh in the Port Sulphur area, Louisiana from 2019.
Microanalysis of samples collected from the Sulfur Springs Draw calcrete-type uranium deposit in the Southern High Plains, Texas, USA Microanalysis of samples collected from the Sulfur Springs Draw calcrete-type uranium deposit in the Southern High Plains, Texas, USA
This data release presents the results of microanalysis of 2 samples SSD15_01A (1 thin section and 1 composite chip sample), and SSD15_01B (1 thin section). The samples were collected in 2015 by U.S. Geological Survey geologists Bradley Van Gosen and Susan Hall from surface exposures of uranium mineralization in Sulfur Springs Draw, in Martin County, Texas (Van Gosen and Hall, 2017). The...
