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.

Well site and construction data for observation wells in well clusters SF-3, SF-4, and SF-5, Buckman well field, Santa Fe County, New Mexico, 1987 Well site and construction data for observation wells in well clusters SF-3, SF-4, and SF-5, Buckman well field, Santa Fe County, New Mexico, 1987
This dataset provides well-site information and construction data for wells SF-3A, SF-3B, SF-3C, SF-4A, SF-4B, SF-4C, SF-5A, SF-5B, and SF-5C that were installed in the Buckman well field, Santa Fe County, New Mexico. The data include well-site information, borehole diameters and depths, well casing and screen diameters and depths, and annular materials and depths. The data were...
Elemental and Lead-Hafnium-Neodymium-Strontium Isotopic Composition of a Suite of Northwest Hawaiian Ridge Postshield Lavas Elemental and Lead-Hafnium-Neodymium-Strontium Isotopic Composition of a Suite of Northwest Hawaiian Ridge Postshield Lavas
The Hawaiian-Emperor chain, the surface expression of the Hawaiian mantle plume which has been active for at least 81 Ma, is divided into the Emperor Seamounts (81-47 Ma), Northwest Hawaiian Ridge (NWHR, 47-6 Ma), and Hawaiian Islands (
Stillwater Complex, Montana—logs of core drilled by Stillwater Mining Company and Anaconda Copper Corp. in the Stillwater Mine area, 1983 to 1989 Stillwater Complex, Montana—logs of core drilled by Stillwater Mining Company and Anaconda Copper Corp. in the Stillwater Mine area, 1983 to 1989
This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and 12 .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from the...
Gunnison sage-grouse predicted gene flow (conductance) surfaces, Colorado, United States Gunnison sage-grouse predicted gene flow (conductance) surfaces, Colorado, United States
Habitat fragmentation and degradation impacts an organism's ability to navigate the landscape, ultimately resulting in decreased gene flow and increased extinction risk. Understanding how landscape composition impacts gene flow (i.e., connectivity) and interacts with scale is essential to conservation decision-making. We used a landscape genetics approach implementing a recently...
Digital database of the previously published bedrock geologic map showing thickness of overlying Quaternary deposits, Grand Island quadrangle, Nebraska and Kansas Digital database of the previously published bedrock geologic map showing thickness of overlying Quaternary deposits, Grand Island quadrangle, Nebraska and Kansas
This digital data release contains geospatial data for the 1:250,000 scale geologic map of the Grand Island 1 degree by 2 degree quadrangle, Nebraska, originally published by Dreeszen and others (1973). The database includes line and polygon features depicting the extent of the Miocene Ogallala Formation and underlying Cretaceous rocks. The original map also included shaded patches...
Digital database of the previously published geologic map of the O'Neill 1x2 degree quadrangle, Nebraska Digital database of the previously published geologic map of the O'Neill 1x2 degree quadrangle, Nebraska
This digital data release contains geospatial data for the geologic map of the O’Neill 1 degree by 2 degree geologic map in Nebraska, originally published in 2008 by R.E. Diffendal and others. The original map consists of a 1:250,000 scale map plate with a “stack unit” structure showing multiple overlying units, as well as several roughly 1:750,000 scale maps in an accompanying pamphlet...
