Flynn Creek crater is a 3.8 km diameter, 360-million-year-old impact structure located in north central Tennessee, and is an invaluable terrestrial analog for the study of impact cratering dynamics. The Flynn Creek Crater Sample Collection consists of over two thousand boxes of drill core from 18 drill holes in the crater’s central uplift, floor, and rim. Impact-induced hydrothermal systems are of considerable scientific interest because they may have played a significant role in the origin and evolution of life on early Earth and produced temporary near-surface habitable environments on Mars. Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater. The drilling...
The Climate Adaptation Science Centers (CASCs) partner with natural and cultural resource managers, tribes and indigenous communities, and university researchers to provide science that helps fish, wildlife, ecosystems, and the communities they support adapt to climate change. The CASCs provide managers and stakeholders with information and decision-making tools to respond to the effects of climate change. While each CASC works to address specific research priorities within their respective region, CASCs also collaborate across boundaries to address issues within shared ecosystems, watersheds, and landscapes. These data represent the 9 CASC regions and the national CASC that comprise the CASC network, highlighting...

Parameter ensemble files required to run the Groundwater Nitrate Decision Support Tool for Wisconsin
A groundwater Nitrate Decision Support Tool (GW-NDST) for wells in Wisconsin was developed to assist resource managers with assessing how legacy and possible future nitrate leaching rates, combined with groundwater lag times and potential denitrification, influence nitrate concentrations in wells (Juckem et al. 2024). The GW-NDST relies on an ensemble of calibrated parameters to make nitrate predictions and to estimate the uncertainty of those predictions. This data release contains all of the calibrated parameter files required to run the tool. The files are packaged in a single ZIP file. To run the tool, the ZIP package needs to be downloaded and extracted within the pest/ies_parameter_ensembles/ subdirectory...

A hydro-economic model was developed by coupling a three-dimensional groundwater flow model of the Harney Basin, southeastern Oregon (using MODFLOW 6) with a hedonic agricultural economic model. The hydro-economic model was used to investigate a set of hypothetical future scenarios having different groundwater pumpage conditions. The model looked at conditions 30 years beyond the 2018 conditions at the end of the HBGM transient simulation. This USGS data release contains all of the input and output files and needed Python scripts and JuPyter Notebooks for the simulations described in the associated journal article (https://doi.org/10.1029/2024WRXXXX)

The data in this data release are from an effort focused on understanding social vulnerability to water insecurity, resiliency demonstrated by institutions, and conflict or crisis around water resource management. This data release focuses on definitions and metrics of resilience in water management institutions. Water resource managers, at various scales, are tasked with making complex and time-sensitive decisions in the face of uncertainty, competing objectives, and difficult tradeoffs. To do this, they must incorporate data, tacit knowledge, cultural and organizational norms, and individual or institutional values in a way that maintains consistent and predictable operations under normal circumstances, while...

Because Indiana has significant resources of coal, coal waste, and coal combustion products that are potential resources of critical minerals, this project developed a data preservation strategy for these coal related materials. Rare Earth Elements (REE) are the principal groups of critical minerals considered in this data preservation project, and our strategy for data preservation is to develop databases for individual groups of coal and coal-related materials. When completed, these databases will be combined under an inteactive application that will allow users to quickly locate selected sites and learn which data are available.
Inductively coupled plasma - optical emission spectrometry (ICP-OES) analysis data compiled using sample preparation procedures outlined by ASTM D2013/D2013M-18 and ASTM D6357, and using two independent sets of element standards for instrument calibration. Additional analysis methodologies are described in detail in the resulting publication Rare earth elements and yttrium in Pennsylvanian coals and shales in the eastern part of the Illinois Basin (Mastalerz et al., 2020).

These catalogs serve to identify known locations of mineral extraction and exploration activities discussed for the purpose of eventually discovering these data through the Mines web map application. These tables of information will reduce data entry time through use of queries to generate records. They also help identify properties without a clear location for efficient discussion with the original authors.

The Geospatial Fabric version 1.1 (GFv1.1 or v1_1) is a dataset of spatial modeling units covering the conterminous United States (CONUS) and most major river basins that flow in from Canada. The GFv1.1 is an update to the original Geospatial Fabric (GFv1, Viger and Bock, 2014) for the National Hydrologic Modeling (NHM). Analogous to the GFv1, the GFv1.1 described here includes the following vector feature classes: points of interest (POIs_v1_1), a stream network (nsegment_v1_1), and hydrologic response units (nhru_v1_1), with several additional ancillary tables. These data are contained within the Environmental Systems Research Institute (ESRI) geodatabase format (GFv1.1.gdb).

Jointly managed by multiple states and the federal government, there are many ongoing efforts to characterize and understand water quality in the Delaware River Basin (DRB). Many State, Federal and non-profit organizations have collected surface-water-quality samples across the DRB for decades and many of these data are available through the National Water Quality Monitoring Council's Water Quality Portal (WQP). For this data release, WQP data in the DRB were harmonized, meaning that they were processed to create a clean and readily usable dataset. The harmonization process included the synthesis of parameter names and fractions, the condensation of remarks and other data qualifiers, the resolution of duplicate...

This dataset includes spreadsheets with statistical data (mean and median absolute error) used in deciding which interpolation method best fit the corresponding dataset. All statistical data were paired with a visual inspection of the interpolation prior to determining the final raster product. All spreadsheets were generated using an automated python script (Jahn, 2020).
This data release includes grids representing the depth and thickness of drinking-water withdrawal zones, polygons of hydrogeologic settings, an inventory of sources of well construction data, and summaries of data comparisons used to assess the depth of groundwater used for drinking-water supplies in the United States. Well construction data sources are documented in Table1_DataSources.xlsx. Data comparisons using the Mann-Whitney test to assess similarity between hydrogeologic settings were used to justify combining data where they were sparse (compare_neighbors_all_domestic.txt and compare_neighbors_all_public.txt). Water-supply-well depth varies geographically by water use and the type of well, which illustrates...
