The input and results tables provide a record of the complete input and output values required for the quantitative assessment of water and proppant associated with oil and gas production for the continuous oil and gas resource in a geologically defined Assessment Unit. The same input form template is used for all such assessments. Each USGS water and proppant assessment builds from a...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of the Larsen Basin, Antarctica. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil and gas...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered shale-oil and shale-gas resources in the Berkine, Illizi, Hamra, Murzuq, and Erdis Kufra Basins of northern Africa. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Woodford and Barnett Shales of the Permian Basin Province, Texas and New Mexico. 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...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of the Santos Basin, Campos Basin, and Espírito Santo Basin provinces of Brazil. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment NAGA Project for...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of South America and the Caribbean. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment (NAGA) Project for the assessment of undiscovered oil and gas...

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photos or topographic surveys, as well as contemporary sources like lidar elevation point clouds and digital elevation models (DEMs). These shorelines are compiled and analyzed in the Digital Shoreline Analysis System (DSAS) software to compute rates of...

Accurate age estimation is crucial for understanding fish population dynamics, yet daily age validation for invasive Grass Carp in the Midwestern U.S. is lacking. We validated daily otolith increment deposition in known-age Grass Carp reared in laboratory and pond environments. Larval Grass Carp from captive broodstock were sampled between 6- and 120-days post-hatch. Lapilli otoliths...

This multi-part, muti-scaled dataset summaries information from field sampling of vegetation plots on the structure and composition of vegetation and habitats that were also sampled for bird communities. Estimates are based on standardized assessments methods such as distance sampling, point-intercept methods, and censuses or stem counts that measure basal area, vegetation cover and...

These data were compiled to investigate competitive interactions between Pleurphis jamesii and other herbaceous plants in a semiarid grassland community. The objectives of our study were to determine whether selective mortality of either C3 or C4 herbaceous plants led to changes in (1) soil moisture during the growing season, (2) water use by Pleuraphis jamesii during the growing season...

This data set includes soil sample and vegetation plot sample data for a project examining the ability of composted soil amendments to improve terrestrial ecological restoration outcomes in a post-contaminant setting. Sites in the Missouri section of the Tri-States Mining District that had been restored and treated with varying levels of composted soil amendments were assessed for...

These data were compiled as part of an experimental study investigating alternative methods to dryland reclamation. The objective of our study was to evaluate the effects of conventional vs alternative approaches alone and in combination that included different seeding methods, seed mixes, and biological soil crust (biocrust) inoculation. These data were collected within the footprint of...
