In August 2017, the U.S. Geological Survey acquired high-resolution P- and S-wave seismic data near six Southern California Seismic Network (SCSN) recording stations in southern California: CI.OLI Olinda; CI.SRN Serrano; CI.MUR Murrieta; CI.LCG La Cienega; CI.RUS Rush; and CI.STC Santa Clara (Figure 1). These strong-motion recording stations are located inside Southern California Edison electrical substations, critical infrastructures that provide essential services to millions of customers. The primary goals of the seismic survey were to understand the potential for amplified ground shaking and to evaluate lateral variability in shear-wave velocity at these sites. We deployed up to 88 geophones at 2-m or 4-m...
Atlas of Wood Pellet Components features compilation of over 300 photographs taken between 2019 and 2021 while the authors (Agnieszka Drobniak, Zbigniew Jelonek, Maria Mastalerz and Iwona Jelonek) were developing methodology of using reflected light microscopy in identification of pellet fuels constituents. These photomicrograps provide documentation of the composition of wood pellets and demonstrate the array of impurities that can be present. As such, this atlas is a valuable source of information for anyone interested in pellet fuels, optical microscopy, and quality assessment techniques.

Inductively coupled plasma - optical emission spectrometry (ICP-OES) analysis data compiled using sample preparation procedures outlined by ASTM D2013/D2013M-18 and ASTM D6357, and using two independent sets of element standards for instrument calibration. Additional analysis methodologies are described in detail in the resulting publication Rare earth elements and yttrium in Pennsylvanian coals and shales in the eastern part of the Illinois Basin (Mastalerz et al., 2020).

Jointly managed by multiple states and the federal government, there are many ongoing efforts to characterize and understand water quality in the Delaware River Basin (DRB). Many State, Federal and non-profit organizations have collected surface-water-quality samples across the DRB for decades and many of these data are available through the National Water Quality Monitoring Council's Water Quality Portal (WQP). For this data release, WQP data in the DRB were harmonized, meaning that they were processed to create a clean and readily usable dataset. The harmonization process included the synthesis of parameter names and fractions, the condensation of remarks and other data qualifiers, the resolution of duplicate...
This atlas features compilation of over 600 microscopic images taken between 2019 and 2021 while the authors were developing methodology of using reflected light microscopy in identification of charcoal-based grilling fuels constituents. These photomicrographs provide documentation of the composition of the fuels and demonstrate the array of impurities that can be present. As such, this atlas is a valuable source of information for anyone interested in grilling, pellet fuels, optical microscopy, and quality assessment techniques.

Open pit uranium mining in Atascosa, Karnes, and Live Oak Counties in the Texas gulf coast region was active during the second half of the 20th century. Understanding the history of these mining operations is important for proper management and restoration. Although some mines have extensive records documenting the locations and extents of mining pits and mine waste-rock piles, and provide descriptions of reclamation activities, abandoned mines with little to no such documentation are present on the landscape. A multiple lines of evidence approach using lidar derivatives and multispectral remote sensing temporal analysis (Stengel, 2022) was developed to (1) identify uranium mine waste-rock, wastewater, and land...
The Indiana Geological and Water Survey received support from the National Geological and Geophysical Data Preservation Program to inventory, reduce, and rehouse 794.7 linear feet of petroleum and water well borehole records into archival-quality boxes, create a dedicated and functional Records Center at its renovated home on IU’s Bloomington campus by installing a high-density mobile shelving unit, and cull resources from 26,000 files housed on its internal server to incorporate usable records into the public-facing IGWS Digital Collections website. These tasks represent ongoing efforts to centralize, consolidate, and enhance public and research access to the physical records displaced during renovation and digital...
CollectiveAccess and ResourceSpace Tandem (CARST) is a novel cyberinfrastructure and standards-based data framework built from free and open-source platforms linked via plugin to promote inter-domain discoverability. The CollectiveAccesss installation schema augments a PastPerfect Museum Software variant developed by Whirl-i-Gig, Inc. with field elements from Darwin Core and Access to Biological Collection Data’s Extension for Geoscience to better support geological and paleontological collections. The tandem plugin was developed in conjunction with AVP. This collections management environment will be made available for reuse by other state geological surveys and the USGS.

Note: This data release is currently under revision and is temporarily unavailable. These produced datasets include water-quality and quality assurance results collected by the USGS and other entities from 1952 to 2016 near the City of Poplar as well as throughout the East Poplar oil field, leachate results collected from drilling core within the Cretaceous Bearpaw Formation and Monoammonium phosphate (MAP) fertilizer results collected by the USGS in 2012. The handling and disposal of the brine has resulted in contamination of not only the shallow aquifers in the East Poplar oil field, but also the Poplar River (Thamke and Craigg, 1997; Thamke and Smith, 2014). The shallow aquifers are the only available source...
In 1926, twenty-four companies from Indiana's Monroe and Lawrence counties joined their limestone quarrying and milling businesses to form the Indiana Limestone Company, or ILCO, that is still in operation today. Indiana Limestone refers to the building-stone facies of the Salem Limestone, later trademarked as “The Nation’s Building Stone,” and has been used extensively in building projects across the United States. Deposited approximately 340–335 million years ago in the middle Mississippian Period, it is exceptionally pure, well sorted, and occurs in thick beds that outcrop at or near the surface in Owen, Monroe, and Lawrence counties making the area especially well suited for profitable quarrying. In 2012,...

The shallow aquifers are the only available source of potable groundwater in the area, and had provided water for more than 100 residents...
