Note: this data release has been deprecated. Please see new data release here: https://doi.org/10.5066/P1EHZNHN. The U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), has compiled Geographic Information Systems (GIS) datasets to assess the vulnerability of streams and stream crossings to erosion and flooding within Acadia National Park, Maine. Erosion

This dataset includes details of 2,745 tracking devices (hereafter "trackers") deployed on shorebirds, including traits of the tags, traits of the shorebirds, and locations of the field sites. The dataset was used in the accompanying paper to evaluate how factors affected "success" of each tag package (tracker + attachment to the bird), where "success" was defined as whether the tag...

These data were compiled to support ecosystem monitoring and management and to inform ecological transition probabilities and drivers. Objective(s) of our study were to produce maps of ecological states each year during 1986-2022 within two dominant ecological site groups (ESGs) in our study area. These data represent annual time series digital maps of ecological states in the Semiarid...

This dataset provides groundwater age estimates for 257 wells used as domestic supply in six selected areas of California. Groundwater ages were estimated by calibration of environmental tracers (tritium, tritiogenic helium-3, sulfur hexafluoride, carbon-14 and radiogenic helium-4) to lumped parameter models (LPMs). Calibrated lumped parameter models provide the optimal mean age and...

This data set describes results for laboratory experiments to determine the efficacy of environmental DNA quantitative PCR assays for four fish species when applied to filtered water samples containing metals mobilized from thawing permafrost.

Data for Figure 2 of U.S. Geological Survey Open-File Report 2021-1045 titled "Methodology and Technical Input for the 2021 Review and Revision of the U.S. Critical Minerals List." The data include the disruption potential, economic vulnerability, trade exposure, and overall supply risk for various mineral commodities in 2018. For some commodities, indicator scores are rounded to avoid

This data release includes information and metrics for evaluating the geomorphic state of barrier islands and headlands along coastal Louisiana. Specifically, these data are: 1) subaerial land coverage; 2) vegetated area coverage; 3) subaerial volume to area ratio from publicly available light detection and ranging (lidar) elevation data; 4) inundation extent (i.e., maps) for high tide...

This data set describes the assessment of surface waters in Denali National Park and Preserve and Wrangell St. Elias National Park and Preserve for antimicrobial resistance genes during four summer months (May - August).

Acoustic telemetry data (Innovasea, Inc.) were collected on invasive Silver Carp (Hypophthalmichthys molitrix) in the lower reaches of the Tennessee and Cumberland river systems to determine timing and environmental conditions associated with dam passages by Silver Carp during 2016–2019. Data also include water level. dam discharge, and lock use data for three dams within these river...

This dataset describes the number and detection of Giardia cysts and Cryptosporidium oocysts in water samples collected from creeks and lakes in Anchorage, Alaska during 2021.

The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Energy and Environmental Protection and the Connecticut Department of Transportation, calculated select streamflow statistics and basin characteristics. This U.S. Geological Survey (USGS) data release provides select streamflow statistics and basin characteristics for 118 streamgages in Connecticut and...

Concentrations of Total40 per- and polyfluoroalkyl substances (PFAS), perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and Total13 PFAS were consistently higher at the AFFF sites compared to the two East Coast reference sites in tree swallow eggs, nestlings, and diet by as much as a factor of 40 times higher. Sites in the Upper Midwest with other PFAS sources also had...
