Data

Locations of hair snares that recorded at least one black bear in western Massachusetts from 2019 and 2021. Sites were located east and west of the Connecticut River.

The table contains observations of American black bears reported by community members to the website: https://massbears.wordpress.amherst.edu from 2019-2023. To preserve the privacy of the contributors, locations were rarefied by 1000 m.

Mercury is a prevalent pollutant and neurotoxin in south San Francisco Bay that forms strong associations with suspended sediments and dissolved organics. Changes in surface water mercury levels have implications for water quality and scale via bioaccumulation to toxicity on higher trophic levels. This dataset includes GeoTIFF raster maps of estimations of surface water mercury...

This data release provides results from laboratory testing of 49 regolith specimens obtained from landslide-prone terrain in Puerto Rico, USA. Specimens were obtained by hand either from the ground surface or from the subsurface using boreholes and hand-excavated pits to a maximum depth of 110 cm. Specimen depths are reliably indicated in the file “Tests-performed.csv” and less reliably...

This dataset contains summarized climate projection and historical climate statistics for selected extreme event and threshold‑based climate variables across the Southeast United States. Data are derived from downscaled CMIP6‑LOCA2 climate model outputs and observed historical precipitation and temperature data. Values are aggregated by U.S. state within the Southeast CONUS region and by

This landing page hosts the datasets associated with a sediment response study of best management practices in agricultural areas. The study was conducted at various sites along Turtle Creek in Union County, Pennsylvania. Datasets developed for this study include site survey data collected at 9 field sites, and very high resolution (VHR) orthomosaics and digital elevation models (DEMs)...

Measurements of water temperature, tide height, and photosynthetic light (PAR: photosynthetic active radiation within the 400-700 nanometers wave band) are provided in four tables for monitoring the abundance and distribution of eelgrass in Izembek and Kinzarof lagoons of Izembek National Wildlife Refuge. These environmental parameters are crucial to the health of eelgrass ecosystems...

We tested eDNA metabarcoding as a monitoring tool to detect freshwater mussel assemblages at the Bennett Island site on the Clinch River. Sampling occurred seasonally from July 2020 through October 2022. We filtered 1L water samples 100 meters upstream and 100 meters downstream of the known mussel assemblage. We amplified and sequenced data at the ND1 and COI markers (Klymus et al., 2021...

This data release contains major ion geochemistry (B, Ba, Br, Cl, Ca, Fe, K, Li, Mg, Mn, Na, Si, SO4, Sr) and total dissolved solids measurements from produced water samples collected from petroleum wells in the Paradox and Uinta Basins, Utah. Analyses were conducted at the U.S. Geological Survey laboratories in Reston, Virginia. The release comprises two files: one metadata file and one...

These data represent annual presence/absence determinations for northern long-eared bats (Myotis septentrionalis) derived from acoustic, mist netting, and artificial roost surveys with associated temporal, climatic, disease exposure, and spatial covariates for the Central Appalachian Mountains, United States, 2003–2023.

This data release contains digital radiometric flight line data for a high-resolution airborne magnetic and radiometric survey over an area of northwest Arkansas (version 2.0, May 2026). Data and documentation for the original version, including associated airborne magnetic data, can be found at https://doi.org/10.5066/P91O2Y8W. The airborne geophysical survey was jointly funded by the...

This data release contains porewater oxygen microprofiling data from abyssal sediment cores collected from the Samoa Basin in the South Pacific Ocean within the American Samoa Exclusive Economic Zone. Sediment cores were collected from 35 locations using a box core that was subsampled with push cores. Push cores were immediately transferred to a cold laboratory van, and oxygen was...
