title: Geospatial data supporting assessments of streamflow alteration to support bay and estuary restoration in the Gulf States

description: The state-of-the-science for implementing restoration of flows for freshwater and estuarine ecosystems health has improved markedly. Many successful examples now exist for improving the timing and delivery of freshwater flows through collaborative processes such as modification of flow regimes through operational changes made through dam re-regulation, dam removal, conservation and efficiency, improved placement and operation of surface and groundwater withdrawals or green infrastructure. Numerous federal, state and local partnerships have already identified such remedies as a high priority for ecosystem restoration1. However, these efforts can often be hampered by the lack of readily available data on stream flows, available gages, and the historical changes in timing and delivery of flow over time, as well as the complex nature of the data and the models needed to interpret the data for decision-making. To address this foundational science and accessibility gap and to facilitate economically and ecologically critical restoration projects, the USGS and the EPA conducted a comprehensive assessment of gages and streamflows for state and local decision-makers to facilitate restoration projects in all five Gulf States and begin a process to install new or restore decommissioned gages.

title: Runtimes for Tests of Array-Processing Speed -- Factorial Tests Using C and C++ Under Windows and Linux

description: The dataset is provided as a .zip archive containing two .csv data files. These two data files contain the results of a series of timing runs made with a suite of 28 C test programs and 20 C++ test programs using three different computers and two operating systems (Windows and Linux). All 48 test programs carry out processing of two-dimensional arrays. One of the files, "C_CppTimeTestsAllRecords.csv", contains three replicated times for each of 960 combinations of factor levels that potentially might have affected the time required to process two-dimensional arrays. The other file, "C_CppTimeTestsAverages.csv", contains the average of the three replicated times for each of the 960 combinations of factor levels. Both files have the same column headers and data formats, and the meaning of the data fields (columns) is the same in both files, with one exception. The exception is that the file for all records contains actual runtimes (in seconds) in the "ProcTime" field, whereas the other file contains averaged runtimes in the "ProcTime" field.

title: Arsenic and Iron data for mass balance calculations to investigate arsenic cycling in a petroleum plume

description: Natural attenuation of organic contaminants in groundwater can give rise to a series of complex biogeochemical reactions that release secondary contaminants to groundwater. In a crude oil contaminated aquifer, biodegradation of petroleum hydrocarbons is coupled with the reduction of ferric iron (Fe(III)) hydroxides in aquifer sediments. As a result, naturally occurring arsenic (As), adsorbed to Fe(III) hydroxides in the aquifer sediment, is mobilized from sediment into groundwater. However, Fe(III) in sediment of other zones of the aquifer has the capacity to attenuate dissolved As via re-sorption. To better evaluate how long-term biodegradation coupled with Fe-reduction and As mobilization can redistribute As mass in contaminated aquifer, we quantified mass partitioning of Fe and As in the aquifer based on field observation data. Results show that Fe and As are spatially correlated in both groundwater and aquifer sediments. Mass partitioning calculations demonstrate that 99.9% of Fe and 99.5% of As are associated with aquifer sediment. The sediments act as both sources and sinks for As, depending on the redox conditions in the aquifer. Calculations reveal that at least 78% of the original As mass in sediment near the oil has been mobilized into groundwater over the 35-year lifespan of the plume. However, the calculations also show that only a small percentage of As mass (~0.5%) remains in groundwater, due to resorption onto sediment. At the leading edge of the plume, where groundwater is suboxic, sediments sequester Fe and As, causing As to accumulate to concentrations 5.6 times greater than background concentrations. However, current arsenic sinks can serve as future sources of arsenic as the plume evolves over time. The mass balance approach used in this study can is applicable to As cycling in other aquifers where groundwater As results from biodegradation of an organic carbon point source coupled with Fe reduction.

title: Bathymetric survey of Rock Run Rookery Lake, Will County, Illinois

description: The bathymetric data set was collected in Rock Run on Dec. 10, 2015 by USGS ILWSC staff Clayton Bosch and Louis Pappas. The bathymetric data were collected with an RD Instruments 1200 kHz ADCP (S/N 8617) and Trimble Ag 162 GPS mounted on the M/V La Moine. A temporary reference point (TRP) was established on the north side of the footbridge over the connecting channel to the Des Plaines River. The mean water surface elevation (504.97 feet, WGS 84) during the survey was established from a temporary reference point whose elevation was later established by GPS survey. The measured depths were then converted to a lake bed elevation. The location and depth data were compiled into a bathymetry dataset (Rock Run Bathymetry Data.csv). The dataset was imported as a shapefile into ArcMap (ArcGIS software 10.3.1). A shape file of lake boundary elevation was developed based on imagery from September 16, 2015 (U.S. Department of Agriculture Farm Services Agency National Agriculture Imagery Program (NAIP)) (point data can be found in Rock Run Lake Boundary.csv). This shape file was merged with the elevation shape file to enforced the lake and island edges in the final bathymetry. This elevation shape file was then contoured using Geostatistical Analyst/Deterministic methods/Radial Basis Functions with Completely Regularized Spline (defaults were used except Sector type: 4 Sectors, Angle: 42, Major semiaxis: 800, Minor semiaxis: 500). The raster was then exported to a GeoTIFF file with a resulting raster cell size of 1 foot.
