Data

This data release contains acoustic Doppler current profiler (ADCP) data collected in 2023 from two uplooking tripods in bays of Lake Ontario in Central New York. Data were collected at Irondequoit Bay (USGS station number 431314077315901) and at Sodus Bay (USGS station number 431533076582101). Data are organized by bay in child item datasets containing the raw binary data files from the...

This data release contains modeled estimates of chlorophyll a concentration and cyanoHAB occurrence for a subset of lakes in New York State. Estimates of chlorophyll a concentration were generated using a random forest model. Estimates of cyanoHAB occurrence were generated based on thresholds derived from bootstrapped logistic regression. All analysis was done in R 4.4.1 (R Core Team...

This data release contains 22 horizontal-to-vertical spectral ratio (HVSR) seismic measurements at 21 sites in Franklin County, New York. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective technique for estimating the thickness of unconsolidated sediments over bedrock. This technique uses a single broadband three...

This data release contains 43 horizontal-to-vertical spectral ratio (HVSR) seismic measurements in Erie, Cattaraugus, and Wyoming Counties, New York collected between 2019 and 2023, in cooperation with the New York State Department of Environmental Conservation. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective...

This data release contains electrical resistivity tomography (ERT) and frequency domain electromagnetic (FDEM) data collected in areas of unwalled shoreline at the Bremerton Naval Complex, WA, June 1-5, 2023. Preliminary inverse results from the FDEM data area also included. Two sites were investigated: Charleston Beach and Segment 4. Charleston Beach is a gently sloping pebble beach...

This data release contains lake and reservoir water surface temperature summary statistics calculated from Landsat 8 Analysis Ready Dataset (ARD) images available within the Conterminous United States (CONUS) from 2013-2023. All zip files within this data release contain nested directories using .parquet files to store the data. The file example_script_for_using_parquet.R contains...

This data release contains Mann-Kendall trend results (p-values and Theil-Sen slope values) of water use data in either 8-digit Hydrologic Unit Code (HUC08) or Van Metre hydrologic regions across the conterminous United States (CONUS) for the period 2000-2020. Trends are computed for 7 timesteps: annual, winter (Dec, Jan, Feb), spring (Mar, Apr, May), summer (Jun, Jul, Aug), fall (Sep...

The dataset is composed of two data tables containing information from boat electrofishing surveys conducted during 2021, 2023, and 2024 in sections of the Mohawk River where it runs separately from the New York State Canal System (i.e., is not canalized). The first table contains fish collection data and the second table contains information on the sampled reaches.

In September and November 2023, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected geophysical surveys of 5 karst drainage features (sinkholes) in eastern Genesee County, New York, in order to study the nature of the subsurface fill material, bedrock topography, and karst dissolution features. Sites were surveyed using...

This data release contains two child item datasets including a compilation of available chloride concentration data in groundwater and related isochlors as well as geospatial data defining the hydrogeologic framework for Kings, Queens, and Nassau Counties in Long Island, New York. These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/lisustainabilityphase1viewer/

This data release contains simulation results from fifteen transient, regional-scale numerical models of the Long Island aquifer system that predict aquifer conditions resulting from possible future changes in pumping and recharge stresses and sea level altitude. These models are based on the MODFLOW 6 numerical model that is documented in Walter and others (2024), which simulates...

This data release contains dissolved cyanotoxin concentrations for microcystins (MC), cylindrospermopsins (CYL), anatoxins (ATX), and saxitoxins (STX) assessed using enzyme-linked immunosorbent assays (ELISA) and liquid chromatography-mass spectrometry or tandem mass spectrometry (LC-MS and LC-MS/MS, respectively) in extracts from SPATT (n=95) and DGT samplers (n=10) deployed on three...
