Data

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

This data release contains raster representations of air temperature, precipitation, and soils across New York State. The environmental data represented by the rasters were identified by Stagnitta and others (2025) as being significant input variables for the computation of low flow statistics across New York State excluding Long Island. The USGS StreamStats application (https://www.usgs...

This data release contains the input data and R scripts to compile streamflow and stream temperature trend outputs (Hecht and others, 2024; Johnson, 2025), calculate Mann-Kendall and Theil-Sen slope trends for driver datasets (Konrad, 2020; PRISM Climate Group, 2014; USGS, 2024), and determine trend likelihood categories and associated driver correlations. The dataset includes 7,655...

This data release contains turbidity and suspended-sediment concentration data used to develop regression models of suspended-sediment concentration at sites in the Esopus Creek watershed in New York. Also included are model summaries describing data-collection methods, application of cross-section coefficients, model development, summary statistics, and related information.

This data release contains site location information, environmental DNA (eDNA) data, and fish capture data from round goby (Neogobius melanostomus) surveys conducted on parts of the Schoharie Creek, New York, during 2024 and 2025. Data were collected in two phases. During Phase 1 (March–July 2024), a rapid assessment of the round goby invasion front (furthest upstream extent of the...

This data release contains frequency domain electromagnetic (FDEM) and passive seismic horizontal to vertical spectral ratio (HVSR) geophysical data collected over and in the vicinity of the Dolores River in Paradox Valley, Colorado. The data collection area is comprised of an approximate 7-kilometer reach of the river and surrounding 100-meter buffer zone on both banks. Water depth and...

This data release contains nutrient, metal, hormone, pharmaceutical, dioxin, and furan concentration data and field readings associated with surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected from April 2023 through October 2023 at nearshore, embayment, and tributary sites from Niagara River...

This data release contains per- and polyfluoroalkyl substances (PFAS) concentration data from surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected monthly from July 2023 through September 2023 at nearshore, embayments, and tributaries from Niagara River to Chaumont Bay. Nearshore and embayment...

This data release contains phytoplankton identification and enumeration data from the analysis of water samples collected from 18 lakes within the Adirondack Park, New York State. Samples were collected as part of the Adirondack Long-Term Monitoring (ALTM) program (for more information, refer to: New York State Energy Research and Development Authority, 2015). The ALTM has monitored...

This data release contains results from the analysis of streambank and adjacent hillslope sediment samples collected from the Stony Clove and Woodland Creek watersheds in the Catskill Mountain region of New York State from July to October 2024. Fourteen or fifteen samples were collected from each of three depositional units ­­— alluvium, glaciolacustrine clay, and glacial till. Results...
