Data

This data release contains input and output files for fifteen (15) MODFLOW 6 models that simulate future groundwater nitrogen transport under potential nitrogen management decisions. The development approach for the flow and transport models is described in Jahn and Walter (2026). Each scenario adjusts nitrogen inputs (Monti and others, 2024) based on communication with local...

This data release contains time-series data sets from two Next Generation Water Observing Systems (NGWOS) innovation test beds (USGS site numbers 01434498 and 01435000) within the Neversink River watershed, New York. These datasets are organized by station-specific child items which include the following components: Piezometer Records – Continuous measurements of specific conductance...

This data release contains analytical results from an experiment examining biofouling of solid phase adsorption toxin tracking (SPATT) samplers deployed between July and September 2024 in two lakes in Central Park (The Lake and Turtle Pond) in New York City, New York, and at an urban wetland in Nashville, Tennessee (Tennessee State University [TSU] wetland). At each site, SPATT samplers...

This data release contains geospatial datasets that map and characterize the hydrogeologic conditions of the Lower Fall Creek unconsolidated aquifer system in Tompkins County, New York. The release includes ten datasets. Nine are shapefiles: the extent of the study area, the aquifer boundary divided into hydrogeologic sections, the stratified-drift aquifer boundary, surficial geology...

This data release contains horizontal-to-vertical spectral ratio (HVSR) passive-seismic sounding data and associated depth-to-bedrock estimates collected at sites in Tompkins and Cortland Counties, New York, between September 2021 and May 2023. The release includes (1) a comma-separated values (CSV) file summarizing each survey, including site name and location, date, land-surface...

This data release contains geospatial data for a region of karst terrain in northern New York State that extends from eastern Lake Ontario and the Mohawk Valley to the state border with Vermont and the United States-Canada border. These geospatial datasets include the location and extent of karstic rock; bedrock geology and elevation; average water-table configuration; surficial geology...

This data release contains continuous (1-hour frequency) groundwater elevation measurements from 48 wells in High Falls and Wawarsing, New York from March 2019 to September 2024. Water depth was automatically recorded using a vented pressure transducer set at a known elevation above NAVD88.

This data release contains training data, digital elevation models, and validation data used to generate and validate deep learning models of surficial geology in two physiographic regions of upstate New York. The two regions are the high-relief Allegheny Plateau and the low-relief Erie-Ontario Lowlands. All deep learning preparation and model creation was conducted with deep learning...

This dataset provides environmental DNA (eDNA) data from samples collected by an autonomous eDNA sampler on northern Lake Champlain at Rouses Point, New York. The sampler was located less than one mile south of the U.S.-Canadian border. The sampler was operated from May 12, 2026 through July 23, 2026 and collected 24 samples and 4 field controls. The samples were analyzed with...

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.
