Data

Groundwater, surface-water, and associated quality assurance samples were collected across western Cape Cod, Massachusetts and analyzed for per- and polyfluoroalkyl substances (PFAS) from September 2019 through November 2024. Water-quality properties measured at the time of sample collection included pH, specific conductance, temperature, and dissolved oxygen. Samples were also analyzed...

Observations of irrigated agricultural land within the Douglas Active Management Area Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on May 28th and again on Aug 9th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and...

Geospatial datasets related to 6PPD-quinone, a compound intended to increase the life span of tires, were acquired and integrated into a relative heat index framework across the conterminous United States. 6PPD-quinone is known to be the cause of Coho Salmon kills following storm events, and more is being learned about the impacts it may have on other species. Sources and influential...

This dataset provides information on aquatic invertebrate composition from ponds (n = 16; surface area 0.02 km2) and lakes (n =16, surface area > 0.10 km2) on the central Arctic Coastal Plain of Alaska. Ponds and lakes were selected for sampling as part of a larger study of Arctic water body food webs. Details on the study area and findings are published in Laske et al. 2018 and Laske et...

Observations of irrigated agricultural land within the Hualapai Valley Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on Jun 6th and again on Aug 13th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for...

Observations of irrigated agricultural land within the Ranegras Plain Groundwater Basin in Arizona. Crops were verified in situ twice in 2024, first on May 15th and again on Sep 10th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with...

Observations of irrigated agricultural land within the Butler Valley Groundwater Basin in Arizona. Crops were verified in situ once in 2024 on May 15th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with the Sentinel2 imagery collection...

Customized products were created for fire management partners in Alaska by leveraging projected Canadian Forest Fire Danger Rating System metrics produced by Young et al. (2025). This input dataset contains daily projections from 1980 through 2099 for key fire danger metrics including Buildup Index, Drought Code, Duff Moisture Code, Fine Fuel Moisture Code, Fire Weather Index, and...

Observations of irrigated agricultural land within the Sacramento Valley Groundwater Basin in Arizona. Crops were verified in situ once in 2024 on Jun 6th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with the Sentinel2 imagery...

This dataset contains 17 fluvial and hillslope planforms for a 2.25 km section of the Nooksack River and adjacent Clay Banks landslide complex in northwestern Washington State spanning 1933-2022. Data include polygon and line features of river and hillslope planform structures for each year including landslides, the active river channel, the floodplain corridor, and vegetated floodplain...

This data release documents five tables and one geographic information systems shapefile feature used to evaluate groundwater quality and concentration trends for groundwater basins in the Gilroy-Hollister Valley and northern San Joaquin Valley, California. This dataset provides a framework for evaluating groundwater quality data at the spatial scale of groundwater basins and the...
