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 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...

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.

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 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...

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.

Data from 10-day sediment toxicity tests of bed sediments from the Buffalo River Area of Concern (AOC) and reference reaches on the Buffalo River upstream of the AOC, Erie County, New York, respectively. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment exposures of two test species, Chironomus dilutus and Hyalella azteca. Sediment samples were collected from 8 sites within the AOC and from 6 reference sites upstream of the AOC. Bed-sediments were collected from depositional areas using a petite Ponar (0.03 square meter) dredge. At each site, approximately five grabs were composited...

The Lake Erie Ecological Investigations (LEEI) dataset, housed at the Great Lakes Science Center (GLSC) was developed during a reevaluation of Lake Erie Areas of Concern (AOCs) from 1998-2000. These AOCs were recognized as such by the International Joint Commission (IJC) of the United States and Canada due to their severe water pollution problems. The dataset includes data from both the 1998-2000 reevaluation as well as data from other historical evaluations from the 1980’s to mid-1990’s for comparison where available. Data Description: Rivers and harbors of the Great Lakes have been impacted for decades by heavy industrialization, densely populated areas, and agriculture resulting in contamination, eutrophication,...

This Fish Community Analysis dataset, a conceptual subgroup of the Lake Erie Ecological Investigations (LEEI) dataset, focuses on the fish communities sampled at Areas of Concern (AOCs) on Lake Erie. Per the Quality Assurance Project Plan (QAPP), fish were sampled for identification and measurement of length and weight. Identification of fish were done by the same biologists for both the 1998-2000 data and the 1986-87 historical data (Smith et al. 1994). Any fish difficult to identify were preserved in buffered formalin for later identification. If large numbers of a particular species were collected the first thirty fish were measured and weighed; remaining fish were individually measured and group weighed. All...
