Data sets containing: (1) sample collection and influenza A virus (IAV) screening information for wild ducks, (2) water temperature data from four wetlands within the Izembek National Wildlife Refuge in Alaska, USA (3) water quality measurement from four wetlands within the Izembek National Wildlife Refuge in Alaska, USA, (4) genetic sequence data for IAVs recovered from replicate samples of wild ducks.

This dataset is three tables with details of samples and aliquots of waterfowl feces deposited in filtered surface water collected from an urban waterbody in Anchorage, Alaska in 2018-2019. Sample vials were submerged underwater in the same waterbody from which the samples were collected and the samples were tested for the presence and viability of influenza A virus. Temperature data and water chemistry measurements were also collected over time.

"In Great Smoky Mountain National Park, it has long been held drinking water should be treated for the water to be drinkable. This research project will focus on water samples from a number of popular Appalachian Trail shelters, as well as more remote areas, after the spring through-hiker season and at the end of fall hiking season. The levels and species of fecal coliform organisms that can cause infectious diarrhea will be determined, which will increase awareness of waterborne illness threats for visitors of the park, and perhaps promote more consistent water purification by backcountry travelers. 7/10 springs were positive for coliforms, 6/10 with E. coli. Coliform counts ranged from 0 - 489 CFU / 100 mL and E coli ranged from 0 - 123 CFU / 100 mL. Spence had the most coliforms, but Silers had the most E. Coli."

Non-biological data (habitat assessment, logger information, water quality data) for spring macroinvertebrate inventory sites at Shenandoah National Park. Dataset as delivered.

This dataset includes microsomal ERDO data from an assay done with liver samples from several fish species that are found in Arizona at sites that are being assessed for PBDE contamination. The data was created in September and October 2016.

Data sets containing: (1) sample collection and influenza A virus (IAV) screening information for wild ducks, (2) water temperature data for six North American wetlands, (3) water quality measurement from those wetlands, (4) laboratory-based study of viral viability using Minnesota wetland water, (5) naive mallards challenged experimentally with IAVs identified from the field experiment, and (6) genetic sequence data for IAVs recovered from the challenge study.

Spatial reconnaissance of fluvial microcystins (MC) concentrations and select water-quality parameters, including nutrients and periphyton biomass, in 75 wadeable streams in the Piedmont region of the southeastern USA during 2014. Data set includes only those data specifically discussed in the associated journal article: Loftin, K.A., Clark, J.M., Journey, C.A., Kolpin, D.W., Van Metre, P.C., and Bradley, P.M., 2016, Spatial and temporal variation in microcystins occurrence in wadeable streams in the southeastern USA: Environmental Toxicology and Chemistry, http://dx.doi.org/10.1002/etc.3391.

This data set is comprised of four files related to the biosurveillance of low pathogenic avian influenza viruses (LPAIV) in migratory waterfowl at 20 locations in the Delmarva Peninsula in fall/winter of 2013-2014. Two files contain data related to the species, age, and AIV prevalence for all birds sampled (1 data file, 1 definitions file). The other two files contain data related to the primers and standards used in bioassays for AIVs (1 data file, 1 definitions file).

A data release containing information on macroinvertebrate communities and sediment toxicity in the Niagara River and adjacent areas collected during a sampling effort conducted between 2019 and 2020, and a sampling effort conducted in 2022. During the first sampling effort, bed sediments were collected at 60 sites in the Niagara River, 5 sites on lower Smoke Creek, and 6 sites on Hoyt Lake for use in sediment toxicity testing and determination of grain size distribution and total organic carbon concentration. Additionally, macroinvertebrate samples were collected from the 60 sites on the Niagara River. During the second sampling effort, bed sediments were collected at 10 sites on lower Smoke Creek (5 of which were repeated from the first sampling effort), 5 reference sites on upper Smoke Creek, and 6 sites on Hoyt Lake (all of which were repeated from the first sampling effort) for toxicity testing, macroinvertebrate community assessment, and and determination of grain size distribution and total organic carbon concentration. Additionally, sediments were collected at 10 sites in the Black Rock Canal, 5 reference sites in the upper Black Rock Canal, and 5 sites in Erie Basin Marina for macroinvertebrate community assessment. The selection of site locations and analyses was done by the U.S. Army Corps of Engineers and the New York State Department of Environmental Conservation based on existing data gaps and prior sediment chemistry data. For both sampling efforts, in situ habitat measurements were taken at the time of sample collection at all sites. All sediment samples were collected using a petite Ponar dredge. Ten-day sediment toxicity tests were performed using two test species, Chironomus dilutus and Hyalella azteca, following standard USEPA test methods. Macroinvertebrates were identified to the lowest practical taxonomic resolution and used to calculate metrics of biological integrity following standard New York State Department of Environmental Conservation procedures. A morphological deformity analysis was also conducted on the mentum mouthpart of midge larvae in the genus Chironomus as an additional measure of toxicity following standard New York State Department of Environmental Conservation procedures. The data release has five separate tables: one containing site locations and habitat information, one containing the results of sediment toxicity tests, one containing macroinvertebrate identifications, one containing standard New York State Department of Environmental Conservation metrics of macroinvertebrate community integrity calculated from the macroinvertebrate identifications, and one containing the results of the morphological deformity analysis.
