The Arizona Bureau of Mines (and later the Arizona Bureau of Geology and Mineral Technology and the Arizona Geological Survey) maintained a significant collection of primary data on mining districts, deposits, and prospects across Arizona. Some of this data has previously been utilized to contribute to earlier efforts by the U.S. Geological Survey to develop the Computerized Resources Information Bank (CRIB) as a centralized repository of organizing and summarizing data on mineral resources in the 1970’s. However, the primary data sources have previously only been available in person at the Arizona Geological Survey offices. Following the transfer of the Arizona Geological Survey to the University of Arizona in...

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...

Digital datasets were used to develop basin characteristics values that are used in multiple regression equations and tested for the use in predicting flow-duration curves (FDCs) in ungaged areas of Indiana. Several basin characteristics are easily derived from StreamStats basin delineations, such as basin area (https://streamstats.usgs.gov/ss/). Other basin characteristics require ancillary datasets as input. The data provided through this data release are those data that have been collected, tested, and ultimately selected as a basis for FDC development. These include PRISM 3-Month Average Precipitation, Thickness and Coarseness of Quaternary Sediments, and Soil Available Water Capacity. There are 6 continuous...

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...

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States' coasts from both older sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. These shorelines are compiled and analyzed in the USGS Digital Shoreline Analysis System (DSAS), version 5.1 software to calculate rates of change. Keeping a record of historical shoreline positions is an effective method to monitor change over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers understand which areas of the coast are vulnerable to change. This data release, and other associated...

This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species are found in multi-species assemblages suggesting that physical factors influence presence similarly across species. In lotic environments, geomorphic and hydraulic characteristics appear to be important factors for predicting mussel presence. We used maximum entropy (MaxEnt) modeling to evaluate hydrogeomorphic variables associated...

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.

This digital dataset contains groundwater level observations for 364 wells, in addition to well construction information, from 1916 to 2014 in the Central Valley, California. Groundwater level observations are used to create groundwater level contours and to calibrate the groundwater levels for the updated Central Valley Hydrologic Model (CVHM2). Groundwater level observations were collected from five sources (USGS, 2018; SLDMWA, 2018; CADWR, 2004; CRNA, 2018).

Arizona’s long history of exploration and mining has resulted in the development of mineral resources across the state. By convention, individual prospects, deposits, and mines into mining districts as an organizational framework to refer to prospective areas for economic mineralization. However, there are no strict definitions of what constitute a mining district other than evidence of mineral potential. Thus, mining districts reflect areas with known mineralization, have diffuse boundaries, and may change over time as new discoveries are made. Mining districts provide a useful framework for both geologists and hobbyists for organizing information, with the past county reports on mineral resources organized from...

This dataset presents the total monthly water withdrawal and consumption estimates for surface-water and groundwater sourced utility-scale thermoelectric power plants by 12-digit hydrologic unit code (HUC12) in the United States for 2015. The water withdrawal and consumption estimate methods and data are published in USGS Scientific Investigations Report 2019-5103 "Withdrawal and Consumption of Water by Thermoelectric Power Plants in the United States, 2015" available at https://doi.org/10.3133/sir20195103. The data release described by this metadata documents the summation of the monthly water withdrawal and consumption estimates by the HUC12 in which the facilities reside. These monthly estimates by HUC12 support...

This dataset is associated with a USGS publication "Assessment of Undiscovered Oil and Gas Resources in the Eagle Ford Group and Associated Cenomanian-Turonian Strata, U.S. Gulf Coast, Texas, 2018" and summarizes data generated by the author for the publication using IHS Harmony DeclinePlus software. Data includes average estimated ultimate recoveries per square mile for three continuous oil assessment units with location information. Data is derived from IHS Markit data. No proprietary information is contained in this release.

Phillip Anderson conducted a comprehensive study of the Proterozoic geology, tectonics, and mineral deposits of the Southwest, focused on Arizona. He started his studies upon arrival at the University of Arizona in the early 1970s, beginning a PhD in the Department of Geosciences. As part of this expansive project, Phil visited and studied nearly every exposure of Proterozoic rocks in Arizona. These studies ranged from detailed quadrangle-scale mapping of large areas to regional reconnaissance accompanied by air-photo interpretation. Phil also collected and geochemically analyzed samples of key rock units, focusing on Proterozoic volcanic and plutonic rocks and their metamorphosed equivalents. He also collected...

Meteor Crater is a 180 m deep, 1.2 km diameter bowl-shaped impact crater in Northern Arizona, and has long been a terrestrial analog site for planetary exploration. During the 1960’s, Eugene Shoemaker trained NASA astronauts at the crater to prepare for the Apollo missions to the Moon. The Meteor Crater Sample Collection consists of geologic samples from the Meteor Crater ejecta blanket. USGS Astrogeology curates and provides access to the Meteor Crater Sample Collection for the planetary science community. Our goal is to facilitate scientific research on impact melting of sedimentary targets, ejecta distribution and deposition processes, and mineral shock metamorphism. The geologic samples in this collection were...
