Borehole geophysical logs near an irrigated field in Fort Irwin National Training Center, San Bernardino County, California, 2018-2020

The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 miles north-northeast of Barstow, California, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle Basins) within the NTC boundaries.  In these basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, managed aquifer recharge using treated wastewater has offset water-level declines in Irwin Basin. Additionally, localized water-quality changes have occurred in some parts of Irwin Basin as a result of human activities (for example, wastewater disposal practices, landscape irrigation, and (or) leaking pipes). 
As part of a research study in cooperation with the U.S. Environmental Protection Agency (EPA), the U.S. Geological Survey (USGS) collected geophysical data to do a site characterization of an irrigated field (Four-plex baseball field) in the Irwin Basin. To aid in the understanding of the subsurface near the Four-plex baseball fields the USGS collected borehole geophysical data during 2018–2020. Natural gamma and neutron geophysical logs were collected in two monitoring wells that were installed by the EPA during 2018–19. Fluid resistivity, natural gamma, and electromagnetic induction logs were repeated in one of the EPA monitoring wells in February 2020; these types of geophysical logs also were collected at a nearby monitoring well on the eastern side of the Four-plex baseball field.

Electrical resistivity tomography data on irrigated fields, Fort Irwin National Training Center, California, 2019-2020

The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 miles north-northeast of Barstow, California, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle Basins) within the NTC boundaries. In these basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, managed aquifer recharge using treated wastewater has offset water-level declines in Irwin Basin. Additionally, localized water-quality changes have occurred in some parts of Irwin Basin as a result of human activities (for example, wastewater disposal practices, landscape irrigation, and (or) leaking pipes). As part of a research study in cooperation with the U.S. Environmental Protection Agency (EPA) and the U.S. Army, the U.S. Geological Survey (USGS) collected eight electrical resistivity tomography (ERT) surveys on five irrigated fields in Irwin Basin in July 2019 and February 2020. The ERT geophysical technique injects direct-current electricity with known voltage and current into the earth using a series of electrodes and measures the resulting resistivity. This technique is generally limited to investigations of aquifer properties that are less than 100 meters below land surface.

Selected products of the scenario HayWired earthquake sequence Hazus analyses for 17 counties in the San Francisco Bay region, California

These data are damage and loss estimates obtained from various Hazus outputs covering all census tracts in 17 counties in and around the San Francisco Bay region in California, for the HayWired earthquake scenario and sixteen M5 or greater aftershocks occurring in the region during the two years following the HayWired mainshock. The HayWired earthquake scenario is a magnitude 7.0 earthquake hypothesized to occur on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. The estimates contained in this dataset are a subset of the many results products generated by FEMA's Hazus-MH 2.1 application, and reflect potential damage due to the HayWired earthquake scenario mainshock and its aftershocks.
The data included in this data release were obtained directly from Hazus or by using Hazus outputs to create derivative results. Products include: Hazus building inventory replacement value estimates, Hazus building contents value estimates, estimates of injuries and fatalities (mainshock and three aftershocks), estimates of displaced households and population requiring short-term shelter (mainshock and three aftershocks), value of building damage estimates (mainshock and sum of mainshock and 16 M5 or greater aftershocks), damage ratio estimates (mainshock and sum of mainshock and 16 M5 or greater aftershocks), estimates of damaged square footage by damage state (mainshock), and direct economic losses (mainshock and 16 M5 or greater aftershocks). For additional information on each dataset, please refer to the metadata accompanying the specific dataset of interest.
These tab-delimited .TXT datasets were developed and intended for use in standalone spreadsheet or database applications (such as Microsoft Excel or Access). Please note that some data included in this data release are not optimized for use in GIS applications (such as ESRI's ArcGIS software suite) as-is--census tracts are repeated (the data are not "one-to-one"), so not all information belonging to a tract would necessarily be associated with a single record. Separate preparation is needed in a standalone spreadsheet or database application like Microsoft Excel or Microsoft Access before using these data in a GIS.
These data support the following publication: Seligson, H.A., Wein, A.M., and Jones, J.L., 2018, HayWired scenario--Hazus analyses of the mainshock and aftershocks, chap. J of Detweiler, S.T., and Wein, A.M., eds., The HayWired earthquake scenario--Earthquake implications: U.S. Geological Survey Scientific Investigations Report 2017-5013-I-Q, 41 p., https://doi.org/10.3133/sir20175013.

Repeat microgravity data from Tucson Basin and Avra Valley, Arizona, 2016-2019 (ver. 2.0, August 2019)

This dataset supercedes an earlier data release and includes all previous data in addition to data from 2019. These data represent the network-adjusted results of relative- and absolute-gravity surveys. Relative-gravity surveys were carried out using a Micro-g LaCoste D-series relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. Vertical gradients between the different measuring heights of the absolute- and relative-gravity meters were measured using a relative-gravity meter and fully-adjustable tripod, and used to correlate the measurements between the two instruments. Relative-gravity differences and absolute-gravity data were combined using a least-squares network adjustment, as implemented in the software Gravnet (Hwang, C., Wang, C., Lee, L., 2002. Adjustment of relative gravity measurements using weighted and datum-free constraints. Comput. Geosci. 28, 1005–1015). Additional information about the network adjustment is provided under Data Quality. Data pre- and post-processing were carried out using GSadjust (https://github.com/usgs/sgp-GSadjust).

Dry Weight, Volume and % Organic Carbon in Mangrove Sediment Cores Collected in September 2018 in J.N. "Ding" Darling National Wildlife Refuge, Sanibel Island, Florida, United States

Sediment cores (1 m in depth) were collected at each of three mangrove sites at J.N. Ding Darling National Wildlife Refuge on Sanibel Island, Florida.  At each site, one core was collected in the hydrogeomorphic zone called the fringe, which is the area directly adjacent to the ocean.  The other core was collected in the zone called the basin, which is the large area, often behind a small berm, that receives less direct tidal energy.  All cores were sectioned and measured for sectional volume, dry weight and % organic carbon (OC) by weight.

Blank results for trace-element data collected for the California Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project, October 2009–October 2018

Groundwater samples have been collected in California as part of statewide investigations of groundwater quality conducted by the U.S. Geological Survey for the Groundwater Ambient Monitoring and Assessment (GAMA) Priority Basin Project (PBP). Quality-control samples are routinely collected as part of the GAMA-PBP quality assurance plan. Olsen and others (2010) and Davis and others (2014) previously determined study reporting levels (SRLs) for trace-element results based primarily on field blanks collected in California from May 2004 through March 2013. SRLs are raised reporting levels used to reduce the likelihood of reporting false detections attributable to contamination bias. Davis and others (2014) reevaluated SRLs defined by Olsen and others (2010) by looking for changes in the pattern or magnitude of field blank detections following the implementation of SRLs by Olsen and others (2010).  Based on a consistent pattern of decreasing cobalt and manganese concentrations in field blanks from 2009 to 2013 the GAMA-PBP decided to reevaluate all trace element study reporting levels (SRLs) defined by Davis and others (2014). Trace element data from 167 field blanks, 19 source-solution blanks, and 8 equipment blanks collected from October 2009 through October 2018 by the GAMA-PBP were compiled as part of the reevaluation and are presented here. The results of the effort to update the SRLs previously defined by Davis and others (2014) are presented here:

Attributes for NHDPlus Version 2.1 Flowlines for the Conterminous United States: 2012 Source Sector Deposition from Community Multiscale Air Quality modeling system (CMAQ)

This metadata record describes 4 tabular data sets that estimate fraction of the total dry or wet deposition due to emissions from fertilizer and animal manure based on output from the Community Multiscale Air Quality modeling system (CMAQ, Zhang and others, 2019) compiled for two spatial components of the NHDPlus version 2.1 data suite (hereto referred as NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2.1 data suite by the unique identifier COMID. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions. Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlusv2 reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).

Discrete and high-frequency chloride (Cl) and specific conductance (SC) data sets and Cl-SC regression equations used for analysis of 93 USGS water quality monitoring stations in the eastern United States

High frequency estimated chloride (Cl) and observed specific conductance (SC) data sets, along with response variables derived from those data sets, were used in an analysis to quantify the extent to which deicer applications in winter affect water quality in 93 U.S. Geological Survey water quality monitoring stations across the eastern United States. The analysis was documented in the following publication: Moore, J., R. Fanelli, and A. Sekellick. In review.  High-frequency data reveal deicing salts drive elevated conductivity and chloride along with pervasive and frequent exceedances of the EPA aquatic life criteria for chloride in urban streams. Submitted to Environmental Science and Technology. 
This data release contains five child items:
1) Input datasets of discrete specific conductance (SC) and chloride (Cl) observations used to develop regression models describing the relationship between chloride and SC
2) The predicted chloride concentrations generated by applying the sites-specific and regional regression models to high-frequency SC datasets
3) The regression equations for 56 USGS water quality monitoring stations across the eastern Unite States, as well as three regions
4) Response variables describing temporal patterns in SC and chloride, calculated by using the estimated high-frequency chloride time series datasets and high-frequency SC datasets
5) Watershed characteristics describing the land use, geology, climate, and deicer application rates for the 93 watersheds included in the Moore et. al (in review) study.

Nanoscale Molecular Fractionation of Organic Matter within Unconventional Petroleum Source Beds (2019)

Fractionation of petroleum during migration through sedimentary rock matrices has been observed across lengths of meters to kilometers. Selective adsorption of specific chemical moieties at mineral surfaces and/or the phase behavior of petroleum during pressure changes are typically invoked to explain this behavior. Given the current emphasis on unconventional (continuous) resources, there is a need to understand petroleum fractionation occurring during expulsion and migration at the nanometer to micron scale, due to the fine-grained nature of petroliferous mudrocks. Here organic matter compositional differences observed within kukersite petroleum source beds (containing acritarch Gloeocapsomorpha prisca) from the Ordovician Stonewall Formation are explored using a suite of optical and spectroscopic methods, most notably through a combined atomic force microscopy - infrared spectroscopy (AFM-IR) approach. The AFM-IR technique is capable of providing spatial resolutions approaching 50 nm and allows for an assessment of the molecular fingerprint of kukersite organic matter across transition zones from organic-rich ‘source’ layers into adjacent carbonate ‘reservoir’ layers ~150 μm away. Our results indicate that the composition of kukersite organic matter begins to vary immediately following expulsion from source layers, with loss of carbonyl groups and a concomitant increase in the CH3/CH2 ratio, indicating alkyl chain-length decrease, as migration distance increases. These chemical transitions correlate with fluorescence decrease, reflectance increase, and an increase in Raman proxies for aromaticity in the organic matter. These data are consistent with the retention of polar compounds onto mineral grains during expulsion and migration, and primacm-1ry cracking and bituminization of the Gloeocapsomorpha prisca kerogen, respectively.

Lithogeochemistry of selected surface and drill core samples from the Chrome and Iron Mountain areas of the Stillwater Complex, Montana

Sulfide- and chromite-bearing samples of the Basal and Ultramafic series of the Stillwater Complex are known to contain elevated concentrations of chromium, nickel, copper, cobalt, gold, and platinum-group elements (PGE). Drill core and surface samples were collected from the Chrome and Iron Mountain areas for whole rock geochemical analysis, with specific interest in PGE, cobalt, and gold concentrations. Core samples are from exploration drilling programs by AMAX in the 1960s and 1970s and Beartooth Platinum in 2004-2007. Reported whole rock data were measured using the following methods: major elements by wavelength dispersive X-ray fluorescence (WDXRF), 60 trace elements by inductively coupled plasma—optical emission spectrometry (ICP-OES), total sulfur and carbon by combustion and infrared detection, ferrous oxide by titration, essential and non-essential water by gravimetric analysis, and gold, platinum, and palladium by lead-fusion fire-assay. Chromitite samples, with greater than 20 wt% Cr2O3, were also analyzed for the full suite of PGE by nickel sulfide fire assay and instrumental neutron activation.
Data are reported in a comma-separated values (CSV) file (Chrome_Iron_Stillwater_Geochemistry) that lists the samples that were analyzed, drill hole identification number and depth (if applicable), latitude/longitude location information, and brief sample descriptions.  All column headings and abbreviations are explained in the accompanying data dictionary (Chrome_Iron_Geochem_DataDictionary).
