The data provided are same-day matchups between in-situ, sonde-based phycocyanin measurements collected across the contiguous United States (CONUS) and Sentinel-2 Level-2A MSI data from 2015 to 2024. The in-situ data are composed of EXO sonde-based phycocyanin measurements, with other optically active water quality constituents included where available. These data are designed for...

This dataset contains ice thickness interpretations made from a radar survey conducted on Gulkana Glacier as part of the USGS Benchmark Glacier Monitoring Program on April 19th and 20th, 2024. The dataset contains a CSV file with the complete set of radar interpretations from the Spring 2024 Gulkana field campaign. The data includes a total of 36,378 observations. Radar interpretations...

The terminal Zuñi Salt Lake is in a broad, low relief volcanic crater, or maar, in west-central New Mexico and contains hypersaline water that has long been used by Native Americans for religious purposes and the collection of salt. In 1986, ownership of the Zuñi Salt Lake was transferred to the Zuni Tribe of the Zuni Reservation, New Mexico, which has managed it as a natural and...

Steep landscapes shaped by glaciers, particularly areas where ice has recently retreated, often experience gravitationally driven slope deformation. We refer to hillslopes that show evidence of such deformation as bedrock instabilities. These deep-seated instabilities may or may not develop into coherent landslides with through-going basal sliding surfaces. In coastal environments...

This U.S. Geological Survey (USGS) data release contains groundwater quality data for twelve wells in Suffolk County, New York and associated quality assurance results. Samples were collected between 2021 and 2023 and analyzed for per- and polyfluoroalkyl substances (PFAS), pesticides, and pharmaceuticals. Measurements of pH, specific conductance, dissolved oxygen, water temperature and...

These datasets provide nest-level and vegetation data collected during a study evaluating the response of upland-nesting waterfowl to habitat management treatments at Grizzly Island Wildlife Area, Suisun Marsh, California, USA, from 2008 to 2013. The study used a Before-After-Control-Impact (BACI) design to assess the effects of upland vegetation treatments (dense nesting cover, native...

This dataset consists of lead concentrations of liver, anterior bone, and posterior bone from gophersnakes (Pituophis catenifer) and Great Basin rattlesnakes (Crotalus oreganus lutosus) found dead along roads in The Morley Nelson Snake River Birds of Prey National Conservation Area in southwestern Idaho, U.S.A. Because this area has been heavily impacted by both military and recreational...

Riparian systems across the southwestern United States are immensely important ecosystems and serve as biodiversity hotspots for a number of plant and animal species. However, recent challenges including non-native vegetation expansion, increased wildfire activity, and widespread vegetation die-offs, have substantially impacted the conditions of these ecosystems. This study was...

Data supporting the journal article titled "Influence of modeling assumptions on pedestrian evacuation success for non-eruptive lahar hazards at Mount Rainier, Washington" as described in the abstract: Previous efforts to characterize lahar threats posed to communities downstream of volcanoes have focused primarily on delineating hazard zones that lack information on lahar-arrival times...

    This data release presents geologic map data for the surficial geology of the Wheeler Peak, Raton, Springer, and Taos 30-minute by 60-minute quadrangles, New Mexico. This 1:100,000 scale geologic mapping incorporates new interpretive contributions and compilation from 1:24,000 to 1:250,000 scale published geologic map data sources. Much of the geology incorporated from previous...

This data release consists of 2 files: 1. MAP_DO.csv contains continuous sensor readings for dissolved oxygen, temperature, conductivity, and pH from 58 stream monitoring locations in the Mississippi Alluvial Plain (MAP) ecoregion in Mississippi, USA. Readings were recorded at 30 minute intervals for a single 24-hour period per monitoring location. The data was collected between 2007 and...
