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 data release includes field measurements and remotely sensed data from two reaches of the Buffalo National River in northern Arkansas acquired in August and September of 2021 to support research on remote sensing of benthic algae from aerial photographs and satellite images. This landing page has links to child items where each type of data can be accessed: Field measurements of water depth and percent cover of benthic algae acquired August 24-25, 2021. This ground-based data set was used to calibrate spectrally based models for inferring water depths from passive optical image data, assess the accuracy of image-derived depth estimates, and train classifications of benthic algal coverage. Digital aerial photographs...

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,...

This dataset has been archived; it has been superceded by version 2.0 (September 2021) which can be found at https://doi.org/10.5066/P9RUUR4L Data from 10-day sediment toxicity tests of bed sediments from the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...

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...

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...
