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.

Self-potential tomography preconditioned by particle swarm optimization—Self-potential monitoring and streamflow data acquired March 26–September 14, 2023 at East Fork Poplar Creek near Oak Ridge Tennessee, with forward and inverse modeling computer scrip Self-potential tomography preconditioned by particle swarm optimization—Self-potential monitoring and streamflow data acquired March 26–September 14, 2023 at East Fork Poplar Creek near Oak Ridge Tennessee, with forward and inverse modeling computer scrip
This data release contains self-potential (SP) monitoring data measured on the flood plain of East Fork Poplar Creek (East Fork) in Oak Ridge, Tennessee and streamflow data measured at streamgage EFK5.4 about 310 meters upstream from the SP monitoring site. Additionally, forward and inverse numerical modeling scripts used to model the electrical-potential field on the East Fork flood...
82.4-kilometer profiles of waterborne self-potential and water-quality data measured August 28–September 1, 2023, in the Trinity River between the Elm Fork confluence and North Texas Municipal Water District Main Stem Pump Station in Scurry, Texas 82.4-kilometer profiles of waterborne self-potential and water-quality data measured August 28–September 1, 2023, in the Trinity River between the Elm Fork confluence and North Texas Municipal Water District Main Stem Pump Station in Scurry, Texas
This data release contains 82.4-kilometer (km) long spatial profiles of geophysical and water-quality properties data acquired along five semi-continuous segments of the Trinity River that were surveyed August 28 – September 1, 2023. The surveyed reaches start at the Elm Fork confluence in the Dallas, Texas metropolitan area and end at a pump station in Scurry, Texas. The geophysical...
Stable oxygen, hydrogen, sulfur, and carbon isotope analyses of mineral deposits and mineral occurrences in southeast Missouri, Alaska, Arizona, Indonesia, Brazil, and China Stable oxygen, hydrogen, sulfur, and carbon isotope analyses of mineral deposits and mineral occurrences in southeast Missouri, Alaska, Arizona, Indonesia, Brazil, and China
Stable isotope analyses are reported (the ratios deuterium/hydrogen, carbon-13/carbon-12, oxygen-18/oxygen-16, and sulfur-34/sulfur-32) for ores and related rocks from the Pea Ridge, Lower Pilot Knob, Bourbon, Iron Mountain, and Kratz Spring iron oxide-apatite deposits in southeast Missouri; the Boss iron oxide-copper-gold deposit in southeast Missouri; the Gagaryah stratiform barite...
Microfossil Samples from the East Pisco Basin, southern Peru Microfossil Samples from the East Pisco Basin, southern Peru
The East Pisco Basin is one of several forearc basins situated on the coastal plain of Peru between the Andean Cordillera and Peru-Chile Trench. During the Cenozoic, successive marine transgressions across the East Pisco Basin deposited sequences of Paleogene and Neogene age. Biochronologic studies suggest that a hiatus of approximately 12 million years (~32-20 Ma) separates the youngest...
Forecasted water temperature in offshore Lake Michigan from 2041-2049 and 2091-2099 Forecasted water temperature in offshore Lake Michigan from 2041-2049 and 2091-2099
Data files contain simulated mean, daily, offshore, water temperatures for 20 vertical depths (ranging 4 to 159 m below the surface) for 9 years in the 2040s (2041-2049) and nine years in the 2090s (2091-2099) at two sites in Lake Michigan. One site is located in the northern basin where the National Oceanic Atmospheric Administration (NOAA) has been maintaining a weather buoy since 1979...
Geospatial Fabric for National Hydrologic Modeling, Alaska Domain Geospatial Fabric for National Hydrologic Modeling, Alaska Domain
The Geospatial Fabric for National Hydrologic Modeling (Viger and Bock, 2014; Bock and others, 2020) is a dataset of hydrographic features and spatial data designed for use within the National Hydrologic Model that covers the conterminous United States (CONUS), Hawaii, and most major river basins that flow in from Canada. This U.S. Geological Survey (USGS) data release consists of the...
