This data release contains coastal wetland synthesis products for the geographic region from Jamaica Bay to western Great South Bay, located in southeastern New York State. Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, and mean tidal range, are calculated for smaller units delineated from a Digital Elevation Model, providing the spatial variability of physical factors that influence wetland health. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing Federal, State, and local managers with...

Introduction In 2012, Hurricane Sandy created an open breach in the barrier island system along the south shore of Long Island, N.Y. This breach formed at a location known as Old Inlet and migrated rapidly westward over the winter storm season following Hurricane Sandy. In response, the National Park Service sought assistance from the USGS New York Water Science Center to help evaluate the hydrodynamics and geomorphology of the breach. The evaluation is centered on measurement of water velocities and depths within the breach, and collection of water levels with the Great South Bay adjacent to the breach. This project is part of a larger ongoing study prepared in coordination with the National Park Service...

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 Water Quality Assessment Project pilot study to describe cyanobacteria and cyanotoxin occurrence in the Nation's large rivers. Phytoplankton were identified to the lowest possible taxonomic level with both abundance (reported as both natural units and cells) and biovolume reported.

From May 2017 to November 2019, the U.S. Geological Survey conducted bathymetry surveys of New York City's East of Hudson Reservoirs. The East of Hudson Reservoirs consist of 16 reservoirs and controlled lakes in Putnam and Westchester County, New York, including Amawalk Reservoir, Bog Brook Reservoir, Boyd Corners Reservoir, Cross River Reservoir, Croton Falls Reservoir, Diverting Reservoir, East Branch Reservoir, Kensico Reservoir, Kirk Lake, Lake Gilead, Lake Gleneida, Middle Branch Reservoir, Muscoot Reservoir, New Croton Reservoir, Titicus Reservoir, and West Branch Reservoir. The East of Hudson Reservoirs form New York City's Croton Water Supply System, and also include parts of the Catskill/Delaware Water...
This dataset provides locations and values of water quality parameters from a four-day survey conducted between August 23, 2016 and August 26, 2016 using an Autonomous Underwater Vehicle (AUV) in Great South Bay, New York. Measured parameters include bottom dissolved oxygen (DO), salinity, specific conductance, water temperature, and pH. During the four day period, data was collected along 15 transects of the Great South Bay, totaling 60,480 observation points. From these point data, rasters showing the spatial distribution of bottom dissolved oxygen were generated using an interpolator in a GIS. A unique raster is provided for each day of the survey. All data files for download are available within 'Child...

This data release contains coastal wetland synthesis products for the geographic region of north shore Long Island, New York. Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, and mean tidal range, are calculated for smaller units delineated from a Digital Elevation Model, providing the spatial variability of physical factors that influence wetland health. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing Federal, State, and local managers with tools to estimate the vulnerability and ecosystem...
This data release contains 1-4 dioxane, per- and polyfluoroalkyl substances (PFAS), chlorofluorocarbons (CFCs), methyl tert-butyl ether (MTBE), and trihalomethanes (THMs) concentration data from groundwater samples collected from 78 monitoring wells in Nassau County New York. Samples were collected from May 2019 through December 2022 at wells ranging in depth from twenty-three feet to 875 feet. All wells were sampled with a submersible pump and a subset of five wells were sampled using a dual membrane passive diffusion sampler for method comparison. Water-quality field parameters (water temperature, pH, turbidity, specific conductance, and dissolved oxygen) were measured during each site visit and are included....

Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the Sediment-Bound Contaminant Resiliency and Response (SCoRR) strategy to define baseline and post-event sediment-bound environmental health (EH) stressors. These data document the location, sampling techniques and field conditions observed while collecting soil and sediment samples from selected stations in the northeastern US during the...

This data release contains spatial datasets of bathymetry, water velocity, water quality, and infrastructure of a 30.8 mile reach of the Old Erie Canal between the Town of DeWitt and its junction with the current Erie Canal of the New York State Canal System in Verona, near Rome, New York during 2018 and 2019, and is released in support of Open-File Report 2021-1125; Wernly, J.F., 2022, Characterization of the bathymetry, hydrodynamics, water quality, infrastructure, and channel condition of the Old Erie Canal from DeWitt to its junction with the current Erie Canal in Verona, near Rome, New York, 2018–19: U.S. Geological Survey Open-File Report 2021–1125, 75 p., https://doi.org/10.3133/ofr20211125
