Data

This data release contains borehole geophysical data (natural gamma, electromagnetic induction (EMI), fluid electrical conductivity, and fluid temperature) and driller's log information (soil texture and descriptions) from several wells and borings at the Havasu Landing marina and hardware store (Chemehuevi Tribe Territory) site. Thirteen wells have both geophysical logging data and...

This data release contains near surface geophysical data (frequency domain electromagnetics [FDEM], direct current electrical resistivity tomography [ERT], ground penetrating radar [GPR], magnetometry [MAG], and passive seismic horizontal to vertical spectral ratio [HVSR]) data collected at the Havasu Landing marina and hardware store (Chemehuevi Tribe Territory) in March 2022. Raw data...

This data release contains Adirondack stream chemistry data collected by the New York State Department of Environmental Conservation Rome, NY field station between 1979 and 2001. These data were previously unpublished or only summarized in associated New York State reports and peer-reviewed journal articles.

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...

This data release contains geospatial data compiled from an investigation into the hydrology of Moreau Lake, in Moreau Lake State Park, Town of Moreau, Saratoga County, New York (Heisig, 2026). This compilation included well logs, seismic measurements, and measurements of water levels in the area to define the hydrogeologic framework and groundwater flow system around the lake...

This data release contains hydrologic and water quality data collected as part of an investigation into the hydrology of Moreau Lake, in Moreau Lake State Park, Town of Moreau, Saratoga County, New York (Heisig, 2026). These data include: 1) discrete and 2) continuous comparison measurements of lake-water levels adjacent groundwater levels at well SA1305, 3) measurements of groundwater...

This data release contains Horizontal-to-Vertical Spectral Ratio (HVSR) data collected between 2017 and 2020 from 73 locations in the area surrounding Moreau Lake, Saratoga County, New York. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and...

This data release contains near-surface geophysical and hydrological datasets collected along a historic coal-mining impacted reach of Nanticoke Creek near Wilkes-Barre, Pennsylvania, which is completely dry at its terminus during baseflow conditions. The release includes specific conductance data from a series of sodium chloride tracer slug injection experiments conducted on June 11...

This data release contains 6PPD-quinone (6PPDQ, 2-anilo-5-[(4-methylpentan-2- yl)amino]cyclohexa-2,5-diene-1,4-dione) concentration data from 14 water samples collected from four stream locations in New York and Pennsylvania. Samples were collected from 2025 to 2026 during storm runoff events (n = 3 - 4 per site), with detected concentrations ranging from 0.29 to 36.49 ng/L. Four samples...

This dataset contains vertical water-quality profiles of the Hudson River collected over two field seasons from May through October 2023 and May through September 2024. Data were collected at 27 equidistant transects along the lower Hudson River from Troy to Riverdale, NY using a stratified random sampling design. Each month, a single sampling location was randomly selected along each...

This data release contains field measurements and discrete surface water sample results for parameters related to the assessment of harmful algal blooms. Field measurements include fluorescent chlorophyll, phycocyanin fluorescence, and photosynthetically active radiation (PAR). Discrete water samples were analyzed for extracted chlorophyll-a and pheophytin-a concentrations, total...

This data release contains data used to characterize the near-surface hydrogeology in the Tully Valley, NY mudboil area. Datasets include: (1) Surface geophysical data (Geophysical.zip) to infer different textures of unconsolidated deposits and zones of anomalously high groundwater specific conductance. These data include valley-wide surveys using two frequency domain electromagnetic
