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.

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...
Tree ring dataset for a regional avalanche chronology in Colorado 1319-2022 Tree ring dataset for a regional avalanche chronology in Colorado 1319-2022
This dataset includes processed tree ring data from avalanche paths throughout Colorado, USA. The data were processed in three distinct phases that resulted in this dataset: collection, processing, and avalanche signal analysis. This dataset consists of samples from 1188 cross-sections and increment cores from 1023 individual trees within 24 avalanche paths across the region. From these...
Simulated snowpack and meteorology at multiple resolutions for three headwater study areas in Colorado, USA, water years 1980-2019 Simulated snowpack and meteorology at multiple resolutions for three headwater study areas in Colorado, USA, water years 1980-2019
This data release includes SnowModel output for three headwater study areas in Colorado at seven spatial resolutions and from two forcing datasets over a 40-year period from water year 1980 to 2019. The resolutions include 30 m, 50 m, 100 m, 150 m, 250 m, 500 m, and 1,000 m. The model was run with a 3-hour temporal resolution from September 1, 1980 to August 31, 2019. Two meteorology...
