Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) in Lake Ontario and Surrounding Tributaries, New York, July to September 2023 Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) in Lake Ontario and Surrounding Tributaries, New York, July to September 2023
This data release contains per- and polyfluoroalkyl substances (PFAS) concentration data from surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected monthly from July 2023 through September 2023 at nearshore, embayments, and tributaries from Niagara River to Chaumont Bay. Nearshore and embayment...
Geophysical, geological, hydrological, and geochemical data for aquifer salinity mapping in the Midway Valley, Kern County, California Geophysical, geological, hydrological, and geochemical data for aquifer salinity mapping in the Midway Valley, Kern County, California
The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board (State Water Board) compiled and analyzed data for mapping groundwater salinity, characterizing aquifer systems, and documenting the effects of oil-field water disposal and well integrity issues in the Midway Valley area of San Joaquin Valley, California, associated with the Midway...
Campaign GNSS Measurements Collected at Newberry Volcano by the Cascades Volcano Observatory Campaign GNSS Measurements Collected at Newberry Volcano by the Cascades Volcano Observatory
This data release contains data collected during campaign Global Navigation Satellite Systems (GNSS; formerly only the Global Positioning System or GPS) surveys conducted at Newberry Volcano. A survey in any given year may contain data from a subset of established sites depending on access, personnel, and the condition of the GNSS monument. For each site, we include raw data in binary or...

Future forest habitat conditions in the Adirondack Region: Developing Inputs for the LANDIS-II model Future forest habitat conditions in the Adirondack Region: Developing Inputs for the LANDIS-II model
This data release includes raster and text input files to initialize and run the forest disturbance and succession landscape simulation model, LANDIS-II with the Biomass Succession extension for the study area in the Adirondacks (ADK) National Park, New York, USA. The goal of this project was to develop inputs to forecast future spruce-fir forest extent using the landscape model LANDIS...
Literature rates of measured methane fluxes from tidal wetland soils to the atmosphere Literature rates of measured methane fluxes from tidal wetland soils to the atmosphere
This data release reports a compilation of the literature that included measurements of both methane gas emission fluxes from the soil to atmosphere, and salinity, in different types of tidal wetlands around the globe. Rates were included for in situ measurements of methane flux in natural tidal wetlands but not experimental treatments or restored wetlands.
