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; t

In 2016, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected horizontal-to-vertical seismic soundings at 31 locations in the Owasco Inlet valley, Cayuga and Tompkins Counties, New York to help determine thickness of the unconsolidated deposits. The HVSR technique, commonly referred to as the passive-seismic method, is used to estim

From 2010 through 2019, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected horizontal-to-vertical seismic soundings at 100 locations in upstate New York and 1 location in Susquehanna County, Pennsylvania to evaluate the technique (control-point measurements) and to support aquifer-mapping projects (Heisig, 2012, 2015). The HVSR te

From 2016 to 2018, the U.S. Geological Survey, in cooperation with The New York State Department of Environmental Conservation, conducted a study of the glacial geology and hydrogeology of valley-fill (sand and gravel) aquifers and surrounding uplands within a 112-square-mile area in southern Otsego and northwestern Delaware Counties, New York, centered around the city of Oneonta. The major valley

This data release contains time domain electromagnetic (TDEM) surveys collected at three different sites in Dering Harbor, Shelter Island, New York. The TDEM surveys were collected in 2018, 2022, and 2023.

From 2016 through 2018, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected horizontal-to-vertical seismic soundings at 71 locations in the major valleys in the Oneonta area, Otsego and Delaware Counties, New York to help determine thickness of the unconsolidated deposits and the bedrock surface elevation. The HVSR technique, commo

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data for samples collected from twelve large river sites throughout the United States, from June through October 2019. All data are reported as raw calculated values and are not rounded to USGS significant figures. The dataset includes all routine and quality assurance/quality control samples collected as part of a National Wat

This data release contains the input, output, and model code used to run a transient simulation of a previously published (Walter and others, 2020) steady-state regional model of Long Island, N.Y. The original model code was updated to MODFLOW 6 (version 6.3.0) and incorporates monthly transient stress periods to simulate conditions from 2005-2019 following methods described in Walter and others (

This U.S. Geological Survey (USGS) data release provides surface water quality and groundwater elevation data collected by USGS personnel within the Central Pine Barrens (CPB) Region of Suffolk County, New York, from October 1, 2021 through September 30, 2022. The data were collected in cooperation with the Central Pine Barrens Commission and the Town of Brookhaven as part of a comprehensive water

This data release contains measurements of acid-neutralizing capacity, conductance at 25 degrees Celsius, and Ca concentrations for headwater stream samples collected from 1988 to 2022 in the Adirondack region of New York. Sample analyses were performed by the Adirondack Lake Survey Corporation (ALSC) laboratory and are adjusted here to be consistent with measurements made in the USGS New York Wat

This dataset enumerates the type, size, and color of microplastic particles collected every two weeks from the Alplaus Kill at Glenridge Road in Schenectady, NY (01355470) between November 2018 and December 2019. Ancillary data include stream discharge, sampling net dimensions, and stream velocity. Sampling and analytical methodology are described in the metadata. 

This data set contains continuous water-surface elevation and water-quality (temperature, specific conductance, salinity, and turbidity) data recorded at 6- and 15-minute intervals, respectively, from two sites in the Bronx on the Harlem River -- Roberto Clemente State Park and Mill Pond Park. Water elevation was monitored every second to detect changes indicative of boat wakes expected to resuspe
