Simulated groundwater residence times in two principal aquifers of the Mississippi embayment physiographic region

Groundwater residence times and flow path lengths were simulated for two major aquifers of the Mississippi embayment region using particle tracking (Pollock, 2012; Starn and Belitz, 2018) in a regional groundwater-flow model (Haugh and others, 2020). The Mississippi embayment physiographic region includes two principal aquifer systems: the surficial aquifer system, which is dominated by the Quaternary Mississippi River Valley alluvial aquifer (MRVA), and the Mississippi embayment aquifer system, which includes deeper Tertiary aquifers and confining units. The groundwater residence time simulation focused on the MRVA and two hydrogeologic units of the Claiborne Group (CLBG) from the deeper system, including the middle Claiborne aquifer (MCAQ) and lower Claiborne aquifer (LCAQ). A previously published groundwater flow model of the Mississippi embayment regional aquifer system provided the flow field for this analysis (Clark and Hart, 2009; Clark and others, 2011; and Haugh and others, 2020). Raster files were produced for seven model layers following the hydrogeologic framework for the MODFLOW groundwater-flow model of the Mississippi embayment from Clark and Hart (2009): one for the MRVA and six for the middle and lower Claiborne aquifers including four representing the MCAQ (layers 5 – 8) and two representing the LCAQ (layers 9 and 10). To determine the groundwater residence time, particles were distributed in model layers representing these aquifers using a volume-weighted algorithm then back-tracked until the particles exited the aquifer system, usually at the water-table surface. Particles were tracked under transient hydrologic conditions from March 31, 2014 backwards to January 1, 1870, then under steady-state conditions until they exited the aquifer system. The simulated residence time of each particle is the time the particle took to travel backwards from its initial location in the aquifer to its source of origin. Groundwater-residence time metrics were generated by statistically summarizing individual particles that started within each model cell. The flow-model grid resolution of one square mile was used to simulate groundwater residence times. The data were then resampled to a 1-square kilometer resolution of the National Hydrologic Grid (Clark and others, 2018). Computed metrics included the minimum, mean, maximum, standard deviation, as well as the 10th-, 20th-, 30th-, 40th-, 50th-, 60th-,70th-, 80th-, and 90th-percentiles along with the minimum, median, and maximum flow path length. Additionally, the portion of young groundwater (&lt; 65 years old) and the mean residence time of the young portion were computed.

Airborne electromagnetic and magnetic survey, western Hualapai Indian Reservation near Grand Canyon West and Peach Springs, Arizona, 2018: Processed AEM data

Airborne electromagnetic (AEM) and magnetic survey data were collected during March 2018 along 1,637 line kilometers over the western Hualapai Reservation and surrounding areas.  The survey was conducted as part of a study of the groundwater resources of the Truxton basin and Hualapai Plateau. The survey was designed to improve our understanding of the geometry the major hydrostratigraphic contacts and regional-scale geologic structures of the study area. 
Minimally processed binary AEM data received from the contractor were imported into the Aarhus Workbench software (Aarhus Geosoftware, Aarhus, Denmark) and processed. Filters were applied to inclinometer and spatial positioning data to smooth raw data and remove sensor drop outs. Altimeter data were filtered, smoothed, and manually edited to correct false altitudes associated with trees and other obstacles, resulting in processed altitude representative of the distance between the AEM sensor airframe and bare earth. Ground surface elevations were imported from the 1 arc second USGS National Elevation Dataset. Raw electromagnetic data were visually examined for couplings and noise associated with infrastructure and considered in the context of the locations of known or suspected infrastructure (power lines, pipe lines, etc...) and magnetic anomalies; impacted data were manually removed. Additional soundings were culled where induced polarization effects were suspected. Culled electromagnetic data were spatially averaged using a sounding distance of 1.5 seconds and trapezoidal filter widths of 6 and 8 seconds applied after gate time 1e-5 and 1e-4 seconds (low moment data) and 6 and 8 seconds applied after 1e-4 and 1e-3 seconds (high moment data). Low-signal data were removed from the averaged data through a combination of filters and manual culling. 
The data provided include fully processed electromagnetic data produced from minimally processed contractor-delivered data, also provided with this data release. The digital data are described in the data dictionary, additional details regarding processing steps are described in the metadata.

Principal components of climate variation in the Desert Southwest

Five principal components are used to represent the climate variation in an original set of 12 climate variables reflecting precipitation and temperature gradients. The dataset provides coverage for four regions (the Sonoran Desert, Mojave Desert, Colorado Plateau, and Southern Great Basin) and three time periods including current climate (defined as the 1980-2010 normal period) and future climate (2010-2040 and 2040-2070 normal periods) under the RCP4.5 and RCP8.5 emission scenarios. Climate variables were chosen based on their known influence on local adaptation in plants, and include: mean annual temperature, summer maximum temperature, winter minimum temperature, annual temperature range, temperature seasonality (coefficient of variation in monthly average temperatures), mean annual precipitation, winter precipitation, summer precipitation, proportion of summer precipitation, precipitation seasonality (coefficient of variation in monthly precipitation totals), long-term winter precipitation variability, and long-term summer precipitation variability. The conversion to principal components both standardizes and accounts for covariation in climate variables, while emphasizing the most important climate gradients across the landscape. 
Raster layers representing each principal component form the input to Climate Distance Mapper (https://usgs-werc-shinytools.shinyapps.io/Climate_Distance_Mapper/), an interactive R Shiny application for matching seed sources with restoration sites. Plant populations are commonly adapted to local climate gradients and frequently exhibit a home-site advantage. For this reason, climate information may serve as a proxy for local adaptation in restoration designs. Climate Distance Mapper allows users to rank the suitability of seed sources for restoration sites by displaying multivariate climate distances (incorporating climate principal components) from user-supplied input points to the surrounding landscape. The application provides functions to match seed sources with current or future climate, guide sampling effort for large scale seed collections, and partition the landscape into suitable areas for different seed sources.

Airborne electromagnetic and magnetic survey, southwestern San Joaquin Valley near Lost Hills, California, 2016: Processed AEM data

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2016 along 1,443 line kilometers in the southwestern San Joaquin Valley near Lost Hills, California. These data were collected in support of groundwater salinity mapping and hydrogeologic framework development as part of the U.S. Geological Survey California Oil, Gas, and Groundwater program and the California State Water Resources Control Board’s Program of Regional Monitoring of Water Quality in Areas of Oil and Gas Production.
Minimally processed binary AEM data received from the contractor were imported into the Aarhus Workbench software (v. 5.6.3.0, Aarhus Geosoftware, Aarhus, Denmark) and processed. Filters were applied to inclinometer and spatial positioning data to smooth raw data and remove sensor drop outs. Altimeter data were filtered, smoothed, and manually edited to correct false altitudes associated with trees and other obstacles, resulting in processed altitude representative of the distance between the AEM sensor airframe and bare earth. Ground surface elevations were imported from the 1/3 arc second USGS National Elevation Dataset (U.S. Geological Survey, https://www.usgs.gov/core-science-systems/ngp/3dep/3dep-product-metadata). The elevations were extracted using bilinear interpolation at the intersection of the AEM measurement points and the 1/3 arc second digital elevation model. Raw electromagnetic data were visually examined for couplings and noise associated with infrastructure and considered in the context of the locations of known or suspected infrastructure (power lines, pipe lines, etc...) and magnetic anomalies; impacted data were manually removed. Culled electromagnetic data were averaged using a filter width of 4 seconds applied to high moment and low moment data. Low-signal data were removed from the averaged data through a combination of filters and manual culling. 
The data provided include fully processed electromagnetic data produced from minimally processed contractor-delivered data, also provided with this data release. The digital data are described in the data dictionary, additional documentation is provided in the metadata.
