Ashtabula habitat restoration orthomosaic and elevation products, September 2021 Ashtabula habitat restoration orthomosaic and elevation products, September 2021
The orthoimagery, digital surface model and point cloud presented here document conditions at the Ashtabula River Area of Concern in Ashtabula, Ohio in September 2021. Imagery documents the result of in-stream and terrestrial habitat restorations that had occurred in 2012. Aerial images were collected using a DJI Phantom with FC6310 sensor flying at a nominal elevation of approximately...
Cuyahoga Gorge pre-restoration orthomosaic and elevation products, Cuyahoga Falls, Ohio, September 2022 Cuyahoga Gorge pre-restoration orthomosaic and elevation products, Cuyahoga Falls, Ohio, September 2022
The orthomosaic, digital surface model and point cloud presented here document conditions at Cuyahoga Gorge Reservoir in Cuyahoga Falls, Ohio in September 2022, prior to planned ecological restoration. Images were collected using a 3D Robotics Solo aircraft with GNSS GPS upgrade, Mission Planner software, and a Pentax Ricoh GRII 3-band digital camera sensor. Imagery acquisition flights...
Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in the Lamine River and Blackwater River, Missouri, 2015 Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in the Lamine River and Blackwater River, Missouri, 2015
In March and September of 2015, the USGS demonstrated the utility of side-scan sonar to image large densities of invasive carp and estimate water volume on the Lamine and Blackwater Rivers, Cooper County, Missouri, USA. A 30-kilometer reach of the Lamine River and 20-kilometer reach of the Blackwater River were surveyed using a Humminbird 1198c sonar system. Fish sampling was conducted...
Plot locations and plant species observed in restored grassland sites at Fernald Preserve, Hamilton, Ohio USA, 2017 Plot locations and plant species observed in restored grassland sites at Fernald Preserve, Hamilton, Ohio USA, 2017
This data set provides lists of plant species observed in 2017 at Fernald Preserve in southwest Ohio, USA using two different survey methods. “Tier1_species.txt” provides a list of plant species observed in a cursory walk-through survey at 8 restored grassland sites. “Tier3_3pecies.txt” provides a list of plant species observed in 44 circular plots (18.5 ft radius or 0.025 acres each)...
Per- and polyfluoroalkyl substance concentrations in water, sediment, particulates, and biota in stream and riparian food webs in the Farmington River watershed (Connecticut, USA), 2020-2023 Per- and polyfluoroalkyl substance concentrations in water, sediment, particulates, and biota in stream and riparian food webs in the Farmington River watershed (Connecticut, USA), 2020-2023
This dataset includes a collection of files related to a project investigating concentrations of per- and polyfluoroalkyl substances (PFAS) in biotic and abiotic compartments of five stream food webs in the Farmington River watershed, Connecticut, USA. The dataset contains aqueous, sediment, and tissue concentrations of 28 PFAS compounds, 19 of which were detected at least once. Aqueous
Condition of invasive and native aquatic plants exposed to varied water temperature, chlorine concentration and exposure time Condition of invasive and native aquatic plants exposed to varied water temperature, chlorine concentration and exposure time
Data include treatment water chemistry data (Chlorine concentration, Dissolved oxygen, water conductivity, pH, alkalinity, and hardness) and condition of test plants evaluated 24 hours after testing and then every 4 days for 30 days. Treatment water chemistry data was collected at the beginning and end of the plant treatment period and a subset of times during the treatment period. Plant...
Response of grass carp eggs to turbulence Response of grass carp eggs to turbulence
We examined enhanced turbulence levels as an alternative grass carp (Ctenopharyngodon idella) control strategy through turbulence-induced mortality at embryonic stages. We exposed pre-water-hardened and water-hardened grass carp eggs to increased levels of turbulence in a grid-stirred turbulence tank to find threshold values of turbulence parameters and shear stresses that have lethal...
Acute and chronic toxicity of uranium mine water on the mayfly (Neocloeon triangulifer) before and after zero-valent iron treatment Acute and chronic toxicity of uranium mine water on the mayfly (Neocloeon triangulifer) before and after zero-valent iron treatment
Acute (96-h) and chronic (14-d) toxicity of uranium pond water, before and after zero-valent iron treatment, was evaluated using the mayfly Neocloeon triangulifer. Water chemistry data characterizing the laboratory-synthesized waters used in the experiment include specific conductance, pH, alkalinity, major-ion, and metal concentrations. Water quality data collected from the test waters...
Data from Ammonia Toxicity exposures with Threatened, Endangered, and At-Risk Freshwater Mussels with a Co-stressor of an Elevated Temperature or Metal Mixture (ver. 1.1, October 2026) Data from Ammonia Toxicity exposures with Threatened, Endangered, and At-Risk Freshwater Mussels with a Co-stressor of an Elevated Temperature or Metal Mixture (ver. 1.1, October 2026)
This dataset provides water-quality measurements and biological response data from 96-hour acute and 7-day chronic laboratory toxicity tests evaluating the effects of ammonia on juvenile freshwater mussels under multiple environmental stressors. Tests were conducted with Green Floater (Lasmigona subviridis), Neosho Mucket (Lampsilis rafinesqueana), and Fatmucket (Lampsilis siliquoidea)...
Respiration and Clearance Rate Data from Subadult Fatmucket (Lampsilis siliquoidea) at Two Different Temperatures Respiration and Clearance Rate Data from Subadult Fatmucket (Lampsilis siliquoidea) at Two Different Temperatures
This data release contains respiration and clearance rate data collected from laboratory experiments. Fatmucket mussels (Lampsilis siliquoidea) were placed in sealed containers to determine their oxygen consumption and excretion rates at two different environmentally relevant temperatures. Mussels were then placed into containers with food to determine how quickly they consume 2-60...
Pre-restoration orthomosaic and elevation products for Erie Ponds at Duluth, Minnesota, August 2020 Pre-restoration orthomosaic and elevation products for Erie Ponds at Duluth, Minnesota, August 2020
The orthoimagery, digital surface model and point cloud presented here document conditions at Erie Ponds of the St. Louis River Area of Concern in Duluth, Minnesota in August 2020, prior to planned ecological restoration. Aerial images were collected using a DJI Phantom with FC6310 sensor at a nominal elevation of approximately 100 meters above the surface of the lake water. Data were...
Known age, pond-spawned Gray Redhorse (Moxostoma congestum) length data Known age, pond-spawned Gray Redhorse (Moxostoma congestum) length data
