Data on 17 metrics of shale gas development in the Pennsylvania portion of the Upper Susquehanna River basin that was collated from a variety of sources and summarized at the upstream catchment scale. Data were also standardized by upstream area and transformed into rank scores based on metric distribution and then summarized into a Disturbance Intensity Index (DII). See Maloney et al. 2018 for detailed descriptions of each data sets and limitations of data. (Maloney, K. O., J. A. Young, S. P. Faulkner, A. Hailegiorgis, E. T. Slonecker, and L. E. Milheim. 2018. A detailed risk assessment of shale gas development on headwater streams in the Pennsylvania portion of the Upper Susquehanna River Basin, U.S.A. Science...

Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geo­logical Survey has developed the Sediment-Bound Contaminant Resiliency and Response (SCoRR) strategy to define baseline and post-event sediment-bound environmental health (EH) stressors. These data document toxicity measured by reduction of the light emission of Aliivibrio (formerly Photobacterium) fischeri and the inhibition of polymerase chain reactions caused by environmental...

We measured the response of plants to disturbance across a gradient in inundation times by transplanting tussocks of Schoenoplectus americanus into mesocosms of different elevation in two marsh organ platforms. Both organs were planted on April 11, 2012 and harvested on August 21, 2012. Plants in one organ were disturbed by clipping all above ground vegetation on June 20 2012 (62 days), and left undisturbed in a control organ. Plant stems were clipped at the soil surface to isolate standing above ground material, and sorted into live and dead fractions by species. Above ground biomass was washed and dried at 70°C to a constant weight.

This database contains aquatic benthic macroinvertebrate abundance data derived from samples collected from 33 75-meter stream site locations within the Delaware Water Gap National Recreation area in September of 2006. The database contains two separate table files (i.e., entities) in csv format: 1) Macroinvertebrate site abundance data and 2) site location data. For macroinvertebrate data, six samples were collected within 2-3 riffle areas within each site location with Portable Invertebrate Box Samplers (0.1-m2 sample area, 350 micron mesh collecting nets). Where possible, organisms were identified to the genus taxonomic level using a stereoscope except for organisms of the family Chironomidae and class Oliogochaeta,...

Brook trout is a species of conservation concern in the eastern US. In 2016, we evaluated brook trout movement patterns in response to food and cover treatments in an experimental stream system using RFID monitoring techniques at the USGS Leetown Science Center in Kearneysville, WV. Brook trout were tagged with 12mm HDX Passive Integrated Transponder (PIT) tags and monitored with Multi-Antenna HDX Readers within each experimental stream riffle. We collected associated data on stream temperature using HOBO temperature loggers (Onset Pro V2) and water quality parameters such as dissolved oxygen, conductivity and pH (YSI Professional Plus multiparameter instrument).

The North American Amphibian Monitoring Program (NAAMP) was a collaborative citizen science effort between the US Geological Survey (USGS) and 26 Partners (state agencies, universities, and nonprofits) for monitoring calling amphibian populations over much of the eastern and central United States. Initiated in 1997 in response to needs set forth by the Declining Amphibian Populations Task Force in 1994 regarding increased anecdotal observations of global amphibian declines, NAAMP was designed to provide scientifically and statistically defensible, long-term distribution and trends data for calling amphibian populations at the state and regional level in the United States. The USGS discontinued coordination of the...

A breach in the White Dam has been proposed to facilitate fish passage. As a Technical Assistance project, the U.S. Geological Survey provided toxicity assessments of sediment samples collected by USEPA personnel. These data describe water-quality conditions in exposure chambers during 42-d sediment exposures using the freshwater amphipod, Hyalella azteca.
This is an antiquated version of the North American Breeding Bird Survey (BBS) dataset that has been superseded by a more recent release. Unless visitors have a specific need for these archived data, they should return to the Main BBS Dataset Page and choose the most recent data release, as that one will include all BBS data released to date. The 1966-2018 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes...

This data set includes metal concentrations measured in a species of earthworm (Eisenoides lonnbergi) collected at various locations on the Patuxent Wildlife Research Center.
Wastewater-based epidemiology (WBE) is used to determine the consumption of, or exposure to, chemicals or pathogens in human populations, and is conducted by collecting representative samples of untreated wastewater (influent) to quantify pathogens shed in the population served by the sampled wastewater system. The Centers for Disease Control and Prevention (CDC) and the US Department of Health and Human Services (HHS), in collaboration with the United States Geological Survey (USGS) and other agencies throughout the federal government, initiated the National Wastewater Surveillance System (NWSS) in response to the COVID-19 pandemic to conduct WBE using analytical methods for the collection and analysis of SARS-CoV-2...

Data are modeled estimates of flow status (inclined, diminished, or indeterminant) for 12 published hydrologic metrics (HMs) that characterize main components of flow regimes (duration, frequency, magnitude, timing, and rate of change). Model estimates came from random forest models independently built for each HM that predict flow status category using drainage area and previously summarized upstream catchment accumulated values (NHDPlus v2.1, 1:100,000 scale) for 15 landscape variables that describe anthropogenic stress related to urban development, agriculture, water usage and augmentation, and drainage area. HM observed data came from Eng et al. (2019) who published quantitative and categorical estimates of...

The exposure of white-footed mice (Peromyscus leucopus) to lead and cadmium and the potential associated toxic effects were examined at three sites contaminated with lead in the Southeast Missouri Lead Mining District and at a reference site. Mice from the contaminated sites showed evidence of oxidative stress and red-blood cell δ-aminolevulinic acid dehydratase (ALAD) activity was depressed by an average of 68% at the most contaminated site. However, histological examinations of the liver and kidney, cytologic examination of blood smears and biomarkers of lipid peroxidation and DNA damage failed to show evidence of toxic effects from lead. The biomagnification ratio of cadmium (hepatic concentration/ soil concentration)...

Data are included for two types of field surveys conducted for freshwater mussels throughout the Susquehanna River Basin (and one site in the Potomac River Basin) in the Mid-Atlantic region of the United States from 2008-2010. Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river (at least 8 in each stream). The number of mussels of each species and associated search time were recorded for each survey section to determine a catch per unit effort (CPUE; number of individuals found per person hour). Within qualitatively surveyed areas, one ~200 meter section of stream was selected in which to conduct quantitative surveys to estimate mussel abundance, assess presence of juvenile...
