This Benthic Invertebrate Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the benthic invertebrates sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), the invertebrate samples were taken from sediments remaining from the sediment analysis. Identification of the invertebrates was completed by the same invertebrate taxonomist for both the 1998-2000 evaluation and 1986-87 historical evaluation (Smith et al. 1994) for increased consistency. Oligochaetes were identified to species if possible, chironomids were identified to genus, as adult specimens are needed for specific identification, and other taxa...

This dataset includes audio-magnetotelluric (AMT) sounding data collected in August 2017 in the Buffalo River watershed of northern Arkansas by the U.S. Geological Survey (USGS). Along with geologic mapping, the USGS used AMT data at 6 sites along a southwest-northeast profile of about 7 kilometers across the inferred northeastern margin of the Bear Creek uplift within the southern Ozark Dome to better constrain the buried, northeastern margin of the Bear Creek uplift.

This data release pertains to a seepage investigation and dye tracing study conducted in the Big Creek watershed of Newton County, Arkansas. The seepage dataset includes geospatial files of discharge measurement points and zero-flow observations along with vector lines delineating losing and gaining stream reaches. The dye tracing dataset consists of geospatial files of monitoring sites, dye injection location, and dye flow paths. Hydrologic systems in karst environments have a high degree of interconnectivity between surface water and groundwater systems. Because of this interconnectivity, activities which occur on the surface in karst environments have a direct impact on the water quality and quantity of karst...

Background: The New York State Department of Environmental Conservation (NYSDEC) and the U.S. Geological Survey (USGS) plan to obtain data on chemical contaminants in fish from multiple Areas of Concern (AOCs) in New York State and use this information to evaluate fish consumption advisories, which are a critical component of most removal criteria for “Restriction on Fish and Wildlife Consumption” beneficial use impairments (BUI). The first project in the Buffalo River AOC will help determine if current fish consumption advisories are appropriate, if they can be modified, and if they support or do not support BUI removal as recommended in the June 2014 “Buffalo River AOC: A Monitoring Plan for the Delisting of...
This data release contains numerous shapefiles that describe baseline characterization of the physical attributes of the riverine ecosystems in two national parks – Ozark National Scenic Riverways (ONSR), Missouri, and Buffalo National River (BNR), Arkansas. The individual metadata associated with each shapefile describe in detail the specific process steps, source inputs for the data, and the specific river the data characterizes.

This Sediment Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the sediments sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), sediment collections were a composite of at least five randomly selected samples collected from each site. Per an internal summary report, sediment samples were collected using a stainless steel Eckman dredge. Analytical methods and QA/QC were directed by the Patuxent Analytical Control Facility (PACF) of the US Fish and Wildlife Service. Per Dora Passino-Reader, the Geochemical & Environmental Research Group at Texas A&M University, College Station performed the analytical chemistry...

Background : Contaminated bed sediments in much of the Buffalo River AOC (Figure 1A, 1B) were removed (dredged) between 2011 and 2015. Plans to monitor and assess the effectiveness of this management action on 8 of 9 beneficial-use-impairments (BUI), included the benthic macroinvertebrate (benthos) BUI, were revised by the Buffalo Niagara Riverkeeper (Riverkeeper, 2014). Funds needed to implement various monitoring efforts proposed in this plan, however, were not available at that time. The USGS-New York Water Science Center (NYWSC) and the NYSDEC propose a collaborative study to evaluate multiple lines of evidence (toxicity of sediments and the condition of benthic macroinvertebrate communities) to determine...

This dataset consists of select contaminants of emerging concern (CEC) including pesticides and transformation products, pharmaceuticals and transformation products, and wastewater indicator compound results measured in 131 surface water, 129 bottom sediment, 7 field replicate, and 6 field blank samples collected from 131 sites located on 27 tributaries of the Great Lakes during the summer of 2019. Samples were analyzed at the U.S. Geological Survey National Water Quality Laboratory (NWQL). Surface water samples were collected and analyzed for 238 pesticides, pesticide transformation products, and surrogate compounds (NWQL laboratory schedule 2437; Sandstrom and others, 2015), 152 pharmaceuticals, pharmaceutical...

This dataset includes the locations for audio-magnetotelluric (AMT) sounding data collected in August 2017 in the Buffalo River watershed of northern Arkansas by the U.S. Geological Survey (USGS). The sites were mostly alongside Osage Creek and its intermittent tributaries. Along with geologic mapping, the USGS used AMT data at 6 sites along a southwest-northeast profile of about 7 kilometers across the inferred northeastern margin of the Bear Creek uplift within the southern Ozark Dome to better constrain the buried, northeastern margin of the Bear Creek uplift.
This data set is a compilation of data from two sampling efforts (2010 and 2014), focused on determining the presence and distribution of organic contaminants throughout the United States portion of the Great Lakes watershed. Water-borne contaminants were monitored in 69 tributaries of the Great Lakes using semipermeable membrane devices (SPMDs), and polar organic chemical integrative samplers (POCIS). Analyses included 185 chemicals (143 detected) including polycyclic aromatic hydrocarbons (PAHs), legacy and current-use pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ether (PBDE) and organophosphate fire retardants, pharmaceuticals, fragrances, industrial chemicals, surfactants, and others.

Multispectral satellite images from two reaches of the Buffalo National River in northern Arkansas were acquired between August 6, 2021, and September 15, 2021, to support research on remote sensing of benthic algae. The images included in this data release were obtained by the WorldView3 and Planet SkySat sensors. The original images were cropped to produce smaller subset images focused on each of the two primary study reaches. In addition, the WorldView3 images were geo-referenced and warped to improve alignment with field measurements. This data release includes a comma-delimited (*.csv) text file with a listing of the satellite images with columns: River, Reach, AcquisitionDate, Sensor, PixelSizeMeters, Projection,...

Digital aerial photographs of the Buffalo National River in northern Arkansas were acquired on August 24, 2021 to support research on remote sensing of benthic algae. The images included in this data release were obtained by the U.S. Fish and Wildlife Service using the following key pieces of equipment: Quest Kodiak K100 aircraft, PhaseOne iXURS-1000 4-band (RGB and NIR) 100 mega-pixel medium format digital camera, SOMAG gyro-stabilized/vibration isolation sensor mounting, and POS AV510 GNSS/IMU navigational system. The original images were processed using photogrammetry software to generate orthophotos for the entire project area, delivered as GeoTIFF tiles. The tiles covering each of the two primary study reaches...

Field measurements of water depth and percent cover of benthic algae were acquired from two reaches of the Buffalo National River in northern Arkansas August 24-25, 2021, to support research on remote sensing of benthic algae from aerial photographs and satellite images. The depth measurements included in this data release were obtained by wading the channel and measuring water depth with a stadia rod. Percent of algae cover on the streambed at each sample point was estimated visually to the nearest 10% on a scale from 0.0 to 1.0. The spatial location of each measurement was obtained using a Leica Zeno GG04 RTK GPS receiver. The map projection and datum for these data are UTM Zone 15 N and WGS84, respectively. This...
