Data

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

From August 2018 to October 2019, the U.S. Geological Survey collected spatially high-resolution water quality data as part of five shoreline synoptic surveys around the perimeters of Owasco, Seneca, and Skaneateles Lakes within the Finger Lakes Region of New York. Water-quality data were collected just below water surface utilizing YSI EXO2 multiparameter sondes and portable nitrate sensors paire

This data release contains motorboat-towed floating transient electromagnetic data collected from the Columbia River near Hanford WA.  Data were collected using a ~16 foot (4.9 meters) outboard motorboat during two field campaigns: July 2021 and April 2022. In total, several hundred linear kilometers of data were collected from a reach of the Columbia that extends from approximately Vernita Bridge

This data release contains geospatial data defining estimates of the depth to water and water-table altitude in the upper glacial and Magothy Aquifers, the potentiometric surface of the confined Magothy and Jameco Aquifers, and the potentiometric surface of the Lloyd and North Shore Aquifers on Long Island, New York. Estimates are based on 502 water-level measurements made in wells across Long Isl

This data release contains modeled daily chlorophyll concentration for 82 streams and rivers across the conterminous United States. Estimates of daily chlorophyll concentration were generated using an extreme gradient boosting (XGBoost) (Chen & Guestrin, 2016) machine learning model and various measures of water quality, reach characteristics, and meteorology.
