Slab2 - A Comprehensive Subduction Zone Geometry Model, Makran Region

Subduction zones are home to the most seismically active faults on the planet. The shallow megathrust interface of subduction zones host our largest earthquakes, and are the only faults capable of M9+ ruptures. Despite these facts, our knowledge of subduction zone geometry - which likely plays a key role in determining the spatial extent and ultimately the size of subduction zone earthquakes - is incomplete. Here we calculate the three- dimensional geometries of all active global subduction zones. The resulting model - Slab2 - provides for the first time a comprehensive geometrical analysis of all known slabs in unprecedented detail.

Model Archive: Simulation of Rhodamine Dye Concentration and Larval Drift, Kootenai River, Idaho

1: Model Archive: Simulation of Rhodamine Dye Concentration and Larval Drift, Kootenai River, Idaho. This archive contains results of lagrangian particle-tracking (LPT) simulations of both the dispersal of rhodamine dye and larval drift.  The LPT model is a research effort and the simulations here provide some of the first experimental validation of the results for dispersal of a conservative constituent (Rhodamine WT-20).  The larval drift simulations however have not been validated and the results should be viewed in this context.  The simulations may contain 20 - 30 Gb of results.  The archive is split into child-items to help distinguish the individual components of the archive and make downloading of large files more manageable in terms of data size.

Data Release for "Role of Fault Gouge during Interaction between Hydraulic Fracture and a Preexisting Fracture"

Enhanced reservoir connectivity generally requires maximizing the intersection between hydraulic fracture (HF) and preexisting underground natural fractures (NF), while having the hydraulic fracture continue to propagate across the natural fractures. Observations of downhole core samples suggest that these natural fractures are in fact veins filled with minerals such as calcite (Mighani et al., 2016). We study this interaction during the approach of a hydraulic fracture to a smooth saw-cut fracture under triaxial stress conditions. The specimen is Solnhofen limestone, a fine-grained (&lt;5 µm grain), low permeability (&lt;10 nD) carbonate. The differential stress (1-20 MPa) and inclination of the fault which determines the approach angle, θ (30, 60°) are the experimental variables. We conduct the experiments on both bare surface and gouge-filled fault surfaces. The gouge is a 1 mm thick crushed powder of Solnhofen limestone with &lt;106 µm grain size. During the hydraulic fracture, acoustic emissions (AE), inferred slip velocity, axial stress and pore pressure are recorded at a 5 MHz sampling rate. 
The hydraulic fracture was able to cross the bare surface fault with small induced fault slip. The fault gouge increased the coefficient of friction significantly from 0.12 (bare, polished surface) to &gt; 0.44 (gouged layer). However, the gouge-filled fault arrested the hydraulic fracture and generated a slip event with different characteristics: 1- The stress drop was larger while the generated AE signals had lower magnitude. 2- Slip velocity recorded by the vibrometer was of the same order of magnitude for the bare and gouge-filled faults, but the slip duration increased from 29 µsec for bare surface to ~2.5 msec (~90 times longer rise time) for the gouge-filled fault. The experiments suggest that the gouge-filled fault can accommodate much larger displacement while promoting slow slip on the fault which is harder to detect as AE signals. The observed long duration slip events are similar to the field observations of the long period and long duration (LPLD) events during the stimulation of clay-rich shale formations (Zoback et al., 2012). While the intrinsic low strength, high ductility, and unfavorably oriented natural fractures in shale formations are expected to reduce the occurrence of induced seismicity, our experiments suggest an additional mechanism for the observed LPLD events, i.e. the role of fault gouge. They also suggest that the microseismic detection techniques may under-predict the stimulated volume as the activation of natural gouge-filled fractures may proceed aseismically.

Quality-control equipment blanks, field blanks, and field replicates for baseline surface-water quality of an area undergoing shale-gas development in the Muskingum River watershed, Ohio, 2015-16.

In 2015-16, the U.S. Geological Survey (USGS), in cooperation with the Muskingum Watershed Conservancy District, conducted a study to assess baseline (2015-16) surface-water quality in six lake basins within the Muskingum River watershed that are in the early years of shale-gas development. Six samples were collected at each of 30 sites to characterize surface-water chemistry over a range of hydrologic conditions. Quality-control (QC) samples collected before and during sampling included blanks and replicates. Blank samples were used to check for contamination during sample collection, processing, equipment cleaning, and/or analysis. Replicate samples were used to determine the reproducibility/variability in the collection and analysis of environmental samples. All QC samples were collected and processed according to protocols described in the USGS National Field Manual for the Collection of Water-Quality Data (U.S. Geological Survey, variously dated). Major ion, nutrient, organic, volatile organic compound (VOC), and radiological results of quality-control analyses for 12 equipment blanks, 22 field blanks, and 19 replicate samples from Muskingum River Watershed, Ohio, 2015-2016. This data set includes one table of Non-Volatile Organic Compounds equipment blank samples, one table of Non-Volatile Organic Compounds field blank samples, one table of Non-Volatile Organic Compounds field replicate samples, one table of Volatile Organic Compounds equipment blank samples, one table of Volatile Organic Compounds field blank samples, and one table of Volatile Organic Compounds field replicate samples.

Acoustic backscatter—Data and Python Code

These data were compiled for investigating the relationship between acoustic backscattering by riverbeds composed of various riverbed substrates (bed sediment), and for developing and testing a probabilistic model for substrate classification based on high-frequency multibeam acoustic backscatter. The model is described in Buscombe et al. (2017). The data consist of various quantities on coincident grids, from various sites along the Colorado River in Grand Canyon, including water depth, bed roughness, the area (or footprint) of the acoustic beam, unfiltered and filtered backscatter magnitude, sediment classification (for each location, 1 of 5 sediment classes in a categorical scheme), and the probabilities for each of 5 classes considered by the model. Files are organized by site, themselves denoted by river mile (RM) which is the linear distance downstream of Lees Ferry, Arizona. The so-called unfiltered backscatter has been corrected for various water, sediment and acoustic variables that might cause backscatter to vary independent of bed sediment, but has not been corrected for the effects of topography. It is shown by Buscombe et al. (2017) that topography has a major influence of the relationship between backscatter magnitude and substrate. Therefore, the topographic effects on backscatter are filtered out, resulting in filtered, or 'compositional' backscatter which is more strongly related to substrate type, and therefore serves as the basic and input to the probabilistic substrate classification model.

Ethanol and sodium acetate as a preservation method to delay degradation of environmental DNA: Data

This data contains environmental DNA (eDNA) sample assay results that were collected from water samples taken from a tank housing Asian carp and placed either on ice or at room temperature. At both treatment temperatures, water samples were left untreated or were treated with an ethanol and sodium acetate solution (EtOH-NaAc). This was done to evaluate an ethanol and sodium acetate solution to maintain the integrity of the DNA samples for the time between collection and lab testing. Every day for 6 days following collection, a subset of the samples was removed from each treatment and DNA was extracted and nuclear and mitochondrial markers were assayed with qPCR. Results showed comparable persistence of DNA between untreated iced samples and samples that received EtOH-NaAc treatment that were kept at room temperature. The data showed that DNA can be amplified from samples preserved using an EtOH-NaAc solution after at least seven days at room temperature.

Soil-Water-Balance (SWB) model data sets for Fauquier County, Virginia, 1996 - 2015

A Soil-Water-Balance (SWB) model was developed to estimate annual recharge and evapotranspiration (ET) for Fauquier County, Virginia, for the period 1996 through 2015. The model was developed as part of a study to assess groundwater availability in the fractured-rock aquifers underlying Fauquier County. The model is documented in the associated report, U.S. Geological Survey (USGS) Scientific Investigations Report 2019-5056. The model was calibrated by comparing annual base-flow estimates from the hydrograph separation technique PART to annual recharge estimates from the SWB model for available years of streamflow record at two sites (01643700 and 01656000) within the model area. Selected SWB model parameters were adjusted to improve model fit. The calibration procedure is documented in USGS Scientific Investigations Report 2019-5056, and calibration results are included in the calibration.xlsx spreadsheet included in this archive.
