Microbial Source Tracking Marker Concentrations in Congaree National Park in 2017-2019, South Carolina, USA Microbial Source Tracking Marker Concentrations in Congaree National Park in 2017-2019, South Carolina, USA
The dataset contains quantitative polymerase chain reaction data for microbial source tracking markers screened on water samples collected from streams and rivers within and bounding Congaree National Park from samples collected throughout the year from December 2017 through June 2019. The number of samples collected per event ranged from 4-16 over the span of 11 sample events.
Microbiology of the Utica Shale Microbiology of the Utica Shale
In order to determine the innate microbial community of shale gas reservoirs and how they are impacted by hydraulic fracturing, this study analyzed biomass collected from produced water and rock from hydraulically fractured wells in the Utica Shale. The samples include rock chips from a drill core from one Utica well, produced water from that same Utica well, and produced water from 12...
Microsatellite genotypes and DNA yield of artificially produced larval pallid sturgeon, Scaphirhynchus albus Microsatellite genotypes and DNA yield of artificially produced larval pallid sturgeon, Scaphirhynchus albus
Data consist of genotypes for pallid sturgeon and paddlefish broodstock and artificially-produced larvae at 19 sturgeon microsatellite loci and four paddlefish loci. Microsatellite genotypes allowed confirmation of homozygous sturgeon DNA and absence of paddlefish DNA in haploid gynogens. Data also consist of DNA yield estimates for haploid gynogens for proof of concept that haploid...
Mineralogical and Chemical Data for Heavy-Mineral Concentrate Samples Collected in the Taylor Mountains Quadrangle, Alaska, 2004-2008 Mineralogical and Chemical Data for Heavy-Mineral Concentrate Samples Collected in the Taylor Mountains Quadrangle, Alaska, 2004-2008
Data for 819 pan concentrated stream-sediment samples, nonmagnetic heavy-mineral concentrate (HMC) samples, and chemical data for 93 of HMC samples. The samples were collected in 2004-2008 as part of a reconnaissance geochemical geological survey of drainage basins mostly in the Taylor Mountains 1:250,000-scale quadrangle in southwestern Alaska. Samples were collected from first- or...
Mineralogy, rare earth elements, and strontium isotopic composition of phosphorites and phosphatized rocks from the Rio Grande Rise, south Atlantic Ocean Mineralogy, rare earth elements, and strontium isotopic composition of phosphorites and phosphatized rocks from the Rio Grande Rise, south Atlantic Ocean
Phosphorites and phosphatized rocks from the summit of the Rio Grande Rise were collected via dredge during the oceanographic research cruise RGR1 to the western RGR. The location (latitude, longitude, depth), mineralogy, concentrations of phosphorus and rare earth elements, and 87Sr/86Sr ratios of phosphorites and phosphatized FeMn crusts, ironstones and carbonates from 10 dredge sites...
Mississippi National River and Recreation Area (MISS): Sonar Data Mapping to Assess Native Mussel Habitat Mississippi National River and Recreation Area (MISS): Sonar Data Mapping to Assess Native Mussel Habitat
The National Park Service (NPS) partnered with the U.S. Geological Survey (USGS) to collect hydroacoustic data of the Mississippi River for the development of high-resolution bathymetry and sidescan imagery. The combined datasets will provide key components to characterizing benthic habitat. These information needs were highly desired by the NPS to more accurately assess environmental...
Model archive for Assessing long-term annual yields of highway and urban runoff in selected areas of California with the Stochastic Empirical Loading Dilution Model (SELDM) Model archive for Assessing long-term annual yields of highway and urban runoff in selected areas of California with the Stochastic Empirical Loading Dilution Model (SELDM)
Municipal Separate Storm Sewer System (MS4) permitees including the California Department of Transportation need information about potential loads and yields (loads per unit area) of constituents of concern in stormwater runoff. These entities also need information about the potential effectiveness of stormwater best management practices (BMPs) used to mitigate the effects of runoff...
Model Archive Summary for acoustic derived suspended-sediment concentration at 14144700 Columbia River at Vancouver, WA Model Archive Summary for acoustic derived suspended-sediment concentration at 14144700 Columbia River at Vancouver, WA
Model archive summary describing the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Columbia River at Vancouver site - USGS site ID# 14144700. The time series suspended sediment data will help determine the suspended sediment concentration at the site in...
Model Archive Summary for Surrogate Regression of Fine-Sediment Particles for Lake Tahoe Tributaries Model Archive Summary for Surrogate Regression of Fine-Sediment Particles for Lake Tahoe Tributaries
This USGS data release presents Model Archive Summaries (MAS) and tabular calibration data used to develop surrogate regressions to estimate fine sediment particles flowing into Lake Tahoe. Fine sediment particles in the size range of 0.5 to 16.0 micrometers (μm) represent the primary size range of suspended sediment responsible for clarity reduction in Lake Tahoe. Models will be used to...
Model Inputs and Outputs for Simulating and Predicting the Effects of Climate and Land-Use Changes on Thermal Springs Recharge: A System-Based Coupled Surface-water and Groundwater Model for Hot Springs National Park, Arkansas Model Inputs and Outputs for Simulating and Predicting the Effects of Climate and Land-Use Changes on Thermal Springs Recharge: A System-Based Coupled Surface-water and Groundwater Model for Hot Springs National Park, Arkansas
This data release contains model input and output files for simulating and predicting thermal spring flows at Hot Springs National Park (HOSP), Hot Springs, Arkansas. A three-dimensional hydrogeologic framework of the Hot Springs anticlinorium beneath Hot Springs National Park was constructed to represent the complex hydrogeology of HOSP and surrounding areas to depths exceeding 9,000...
Model of groundwater flow, gas migration, and reactive transport in the Virgin River Basin, SW Utah Model of groundwater flow, gas migration, and reactive transport in the Virgin River Basin, SW Utah
To better understand the possible risks posed to shallow groundwater resources by geologic carbon sequestration (GCS), a multi-scale numerical modeling approach was invoked using the TOUGHREACT code from Lawrence Berkeley National Laboratory. The code solves coupled equations representing conservation of mass and energy on a finite difference grid to simulate multiphase, multicomponent...
Model Output Tabular Summaries for Central Valley Water and Land Use Futures: Land Use Change, Flooded Area, and Flooded Habitat Change Model Output Tabular Summaries for Central Valley Water and Land Use Futures: Land Use Change, Flooded Area, and Flooded Habitat Change
To support coordinated conservation, wetland restoration, and climate adaptation planning, we have developed five future scenarios of the Central Valley's seasonally flooded cropland and wetland waterbird habitat based on the State's most recent climate and land use projections (Wilson et al. 2021).The USGS Western Geographic Science Center and Point Blue Conservation Science modeled a...
