High resolution earthquake catalogs from the 2018 Kilauea eruption sequence High resolution earthquake catalogs from the 2018 Kilauea eruption sequence
The 2018 Kilauea eruption and caldera collapse generated intense cycles of seismicity tied to repeated large seismic (Mw ~5) collapse events associated with magma withdrawal from beneath the summit. To gain insight into the underlying dynamics and aid eruption response, we applied waveform-based earthquake detection and double-difference location as the eruption unfolded. Here, we...
Videos collected for Image Velocimetry at Boneyard Creek at Urbana, IL from 2017 to 2018 Videos collected for Image Velocimetry at Boneyard Creek at Urbana, IL from 2017 to 2018
The U.S. Geological Survey is testing deployments of continuous Large-Scale particle Image Velocimetry (LSPIV) streamgaging stations in areas with flashy flow regimes to measure streamflow during flood events. Videos were collected for the purpose of LSPIV streamflow analysis at a stage-discharge streamgaging station in a small, flashy urban stream in Urbana, Illinois, USA (Boneyard...
Surface-Water Geochemistry of Mercury, Methylmercury, Nutrients, and other Constituents in Clear Lake, Lake County, California, July 2019 Surface-Water Geochemistry of Mercury, Methylmercury, Nutrients, and other Constituents in Clear Lake, Lake County, California, July 2019
Clear Lake is a 180 km2 freshwater lake located in the California Coast Range, approximately 120 km northwest of Sacramento. The lake supports a wide variety of fish and bird species and is a very popular sport-fishing destination. However, fish consumption advisories associated with mercury (Hg) contamination exist for several popular recreational species. The lake is comprised of three...
Geochemical and X-ray diffraction analyses of drill core samples from the Canyon uranium-copper deposit, a solution-collapse breccia pipe, Grand Canyon area, Coconino County, Arizona Geochemical and X-ray diffraction analyses of drill core samples from the Canyon uranium-copper deposit, a solution-collapse breccia pipe, Grand Canyon area, Coconino County, Arizona
This data release compiles the major and trace element analytical results of drill core samples that typify the uranium-copper ore bodies of the Canyon deposit, located about 6.1 miles (10 km) south-southeast of Tusayan, Arizona. The Canyon deposit lies from about 750 to 2,000 ft (230 to 610 m) below the surface at latitude 35.88333 North, longitude -112.09583 West (datum WGS 1984)...
Hilaria jamesii data for the Colorado Plateau of the southwestern United States Hilaria jamesii data for the Colorado Plateau of the southwestern United States
These data were compiled to investigate the demographic, phylogeographic, and adaptation history of Hilaria jamesii. The data release consists of three tab delimited text files that may be used to infer population structure or putative adaptive loci (hija_adaptation_dataset.stru), relationships among sampling localities (hija_phylogeny_dataset.phylip), or genetic diversity statistics...
SUTRA model used to evaluate groundwater availability in central Molokai, Hawaii SUTRA model used to evaluate groundwater availability in central Molokai, Hawaii
A three-dimensional, variable-density solute-transport model (SUTRA) was developed to evaluate the effects of nine selected withdrawal/recharge scenarios on salinity of groundwater and discharge of freshwater to the nearshore environment of central Molokai, Hawaii. The model was constructed using water-level and salinity data available for the period from 1940 to 2012. Groundwater...
FLASH-R (Flow-Log Analysis of Single Holes) FLASH-R (Flow-Log Analysis of Single Holes)
FLASH-R (Flow-Log Analysis of Single Holes) is an R app for the analysis of borehole vertical flow logs to estimate fracture (or layer) transmissivities and far-field hydraulic heads. This app is a new version of the FLASH spreadsheet tool by Day-Lewis et al. (2011) . The program is written in R, an open-source environment. All previous features have been retained and new features...
Estimates of mineral abundances based on Rietveld refinement of X-ray diffraction data from mill tailings and other ore processing materials Estimates of mineral abundances based on Rietveld refinement of X-ray diffraction data from mill tailings and other ore processing materials
This worksheet displays the results of mineral abundance estimates based on Rietveld refinement of X-ray diffraction (XRD) analyses of mill tailings and other ore processing materials from worldwide localities. Data are also provided to show variation in mineral abundance estimates for subsplits in individual samples. Samples were analyzed using a PANalytical X'Pert Pro diffractometer...
Fire Danger Products for the Conterminous United States during 2019 Fire Danger Products for the Conterminous United States during 2019
FGDC Metadata templates for 5 product areas during 2019 have been created to programmatically generate metadata for the products that are produced daily or weekly on the FireDanger production system. Fire Danger products are broken into 5 product areas (Fire Potential Index, Large Fire Probability, Predictive Service Area (provisional), Relative Greenness (weekly), and NDVI Greenness...
Data and regression models describing biofilms and water quality in streams surrounding Milwaukee Mitchell International Airport, Milwaukee, Wisconsin (2009-2014) Data and regression models describing biofilms and water quality in streams surrounding Milwaukee Mitchell International Airport, Milwaukee, Wisconsin (2009-2014)
Heterotrophic biofilm growths were monitored in sites upstream and downstream of Milwaukee Mitchell International Airport, in Milwaukee, Wisconsin; samples were collected primarily during and surrounding the 2009-2010 and 2010-2011 deicing seasons, with additional sample collection occurring in 2014. Biofilms were assessed using both field surveys and modern genetic approaches, and...
Pallid sturgeon seasonal habitat selection in a large free-flowing river, the lower Mississippi River, 2009-2015-Data Pallid sturgeon seasonal habitat selection in a large free-flowing river, the lower Mississippi River, 2009-2015-Data
The data was collected at two lower Mississippi River sites and consists of year round pallid sturgeon Scaphirhynchus albus capture attributes (including habitat type at capture location) from 116 telemetry-tagged fish and habitat area estimation for the sites.
Compilation of data not available in the National Water Information System for domestic wells sampled by the U.S. Geological Survey in Clinton County, Pennsylvania, May-September 2017 Compilation of data not available in the National Water Information System for domestic wells sampled by the U.S. Geological Survey in Clinton County, Pennsylvania, May-September 2017
This dataset contains the lithologic class and topographic position index information and quality-assurance and quality-control data not available in the online National Water Information System for 54 domestic wells sampled by the U.S. Geological Survey in Clinton County, Pennsylvania, May-September 2017. The topographic position index (TPI) for each well location was computed on the...
