Frequency domain electromagnetic induction (FDEM) data were collected in September 2016 near the Agashashok River and its tributaries, within the Noatak National Preserve near Kotzebue, AK to aid in local permafrost mapping. Data were collected with a GEM-2 instrument (1.6 m coil separation, Geophex, Ltd.); a broadband sensor that measures the bulk conductivity and magnetic susceptibility of the subsurface to approximately 5-10 meters depth. The instrument is hand carried by a single operator and data are collected at walking speeds.
The upper Esopus Creek is the primary tributary to the Ashokan Reservoir, part of the New York City (NYC) water supply system. Suspended-sediment concentration (ssc) and turbidity are primary water-quality concerns in the NYC water-supply system, particularly in the upper Esopus Creek watershed. In 2016 the NYC Department of Environmental Protection and U.S. Geological Survey entered into a collaborative agreement to conduct a comprehensive study of suspended sediment and turbidity in the upper Esopus Creek watershed. Objectives included ssc, streamflow, and turbidity monitoring, and development of turbidity-ssc regression equations to estimate ssc from continuous turbidity measurements. Cross-section and point...

This data release contains the output from a Soil-Water-Balance (SWB) model (Westenbroek and others, 2010), used to estimate potential recharge to the Long Island regional aquifer system from 1900-2019. Output data for two SWB simulations are included. The first simulation uses available land-use/land-cover datasets to estimate recharge with changing land use from 1900-2019 (referred to as the post-development simulation). The second simulation assumed a forested, undeveloped (predevelopment simulation) condition across Long Island for the same period. The same soil coverages and time-series climate data were used throughout both simulations. Potential recharge was spatially distributed as gridded output across...
This U.S. Geological Survey data release provides surface-water quality, streamflow, and groundwater-elevation data collected within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2020 through September 30, 2021. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a five-year comprehensive water-resources monitoring program. Water quality and quality-assurance data from seven sites on two rivers (Carmans River- five sites and Peconic River- two sites) in the CPB are included. Carmans River sites were sampled four times throughout the year (fall, winter, spring, and summer) and Peconic River sites were sampled twice...

This data release contains results of a high-water mark survey across Upstate New York following flash flooding during July 9-10, 2023. The survey was conducted between July 12 and September 20, 2023 by U.S. Geological Survey (USGS) personnel, and is based on surveyed elevations of mud, debris, and seed lines (Koenig and others, 2016) left by the flooding. Real-time and static Global Navigation Satellite System (GNSS) surveying (Rydlund and Densmore, 2012), combined with differential leveling (Kenney, 2010), were used to determine high-water mark elevations at 186 locations. Additional data associated with the July 2023 flooding, such as photos of the survey locations, can be found in the USGS Flood Event Viewer,...

This dataset contains a comparison of chemical analysis results obtained by the U.S. Geological Survey (USGS) New York Water Science Center Soil and Low-Ionic Strength Water Quality Laboratory and the Adirondack Lake Survey Corporation (ALSC) Laboratory. Duplicate samples were collected biweekly from Buck Creek and the North and South Tributaries of Buck Creek from September 5, 2006, through September 2, 2008, to be analyzed in each laboratory. The 155 pairs of samples collected over 2 years enabled comparisons to be made under a variety of flows and seasons, using the markedly different chemical characteristics of the three streams. An additional 6 duplicate samples collected in 2016-2017 from Buck Creek were...

This data release contains digital hydrogeologic datasets compiled for eight valley-fill aquifer systems in upstate New York. The data sets include input data necessary to create and interpolate the hydrogeologic framework of the aquifers and surrounding till-covered uplands. Input data is provided as point feature classes and georeferenced files of previously published reports along with the digitized data as line or polygon feature classes. Feature class datasets are provided for convenience and may contain subtle differences to shapefiles due to inherent differences in file types. The data release is composed of eight child items, one for each valley-fill area. Each child item contains the data pertaining...
Near-surface geophysical data from within the Bonita Peak Mining District in Silverton, Colorado, USA are presented. These data were collected in 2019. The data include fiber optic distributed temperature sensing (FO-DTS) and frequency domain electromagnetic induction (FDEM) data collected in and around roughly 1 km reaches of Cement Creek and California Gulch. Additional data, including ground penetrating radar (GPR) and self potential (SP), were gathered from a peatland that intercepts acid mine drainage from Mogul Mine into Cement Creek. The peatland is located off the eastern bank of Cement Creek in the northern portion of the reach surveyed with FO-DTS and FDEM. In 2021, an FO-DTS, FDEM, and magnetometer (MAG)...

A total of 119 passive seismic soundings were collected with Tromino (MoHo s.r.l.) 3-axis seismometers in the Fountain Creek area to partially refine alluvial aquifer thickness (depth to bedrock) estimates, particularly over known or suspected paleochannels. Data were collected during June 21-24, 2021 with a team of 4-5 people, each equipped with a Tromino Blu or Tromino 3G passive seismometer. A subset of the data included measurements made for shear velocity calibration; this included data collected at 10 well sites where depth to bedrock was available from driller's logs, and 3 sites above cutbanks where bedrock outcropped and the thickness of alluvial sediments could be directly measured. Data were processed...
Twenty-six time-domain electromagnetic (TDEM) soundings were collected on Shelter Island, New York between March of 2017 and October of 2018. Soundings were collected using the Geonics ProTEM and ABEM WalkTEM acquisition systems. Depending on the size of the site, one of the following square-loop transmitter geometries was used: 1) 20 by 20 meter, 2) 40 by 40 meter, or 3) 100 by 100 meter. A high-frequency receiver with an effective area of 31.4 m^2 was used with the Geonics ProTEM system. With the ABEM WalkTEM system, a central induction array was used with two square receiver loops (0.5 by 0.5 meters and 10 by 10 meters) setup within the transmitter loop; the two receiver loops created effective receiver areas...
In 2015, the U.S. Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), began an appraisal of the sand and gravel aquifers within the Owasco Inlet watershed, which covers about 117 square miles (mi2) and drains north directly to Owasco Lake, one of New York’s Finger Lakes. About three-quarters of the watershed is within Cayuga County; the remaining area (southern end) is in Tompkins County. The Owasco Inlet valley stretches about 18 miles (mi) from Owasco Lake south to the divide at Freeville. Major tributaries include Hemlock Creek on the west side of the watershed and Dresserville and Decker Creeks on the east side. A variety of data were compiled,...
