Application of a prior-based model discrimination framework using synthetic MODFLOW 6 groundwater models Application of a prior-based model discrimination framework using synthetic MODFLOW 6 groundwater models
A synthetic one-dimensional groundwater flow model was developed using MODFLOW 6 as a test application of the prior-based model discrimination method described in the associated publication (https://doi.org/10.1029/2025WR040323). The model represents a steady-state unconfined aquifer where water flows horizontally between two constant head boundaries (a lake at the lefthand side and...
SWAT Outputs for Baseline Soil and Water Assessment for Los Planes Watershed, Baja California Sur, Mexico SWAT Outputs for Baseline Soil and Water Assessment for Los Planes Watershed, Baja California Sur, Mexico
This data release contains Soil Water Assessment Tool (SWAT) outputs (.shp) for three precipitation scenarios for the Los Planes watershed in Baja California Sur, Mexico. The inputs used are publicly available low-resolution data from international sources to produce uncalibrated baseline model conditions. The outputs for each scenario include annual average surface runoff (mm), sediment...
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.
USGS National and Global Oil and Gas Assessment Project—Gulf Coast Mesozoic Province, Haynesville Formation Water and Proppant Assessment: Assessment Input Tables and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—Gulf Coast Mesozoic Province, Haynesville Formation Water and Proppant Assessment: Assessment Input Tables and Fact Sheet Data Tables
The input and results tables provide a record of the complete input and output values required for the quantitative assessment of water and proppant associated with oil and gas production for the continuous oil and gas resource in a geologically defined Assessment Unit. The same input form template is used for all such assessments. Each USGS water and proppant assessment builds from a...
Sierra Nevada Ecoregion LiDAR and Fuels Data, Collected in 2025 Sierra Nevada Ecoregion LiDAR and Fuels Data, Collected in 2025
Vegetation structure and fuels data are essential for understanding fire behavior following management treatments such as mechanical thinning and prescribed burning. To evaluate these processes, 133 plots were established between July 17 and September 21, 2025 across national forests and parks in the Sierra Nevada. These plots consisted of treated and untreated areas for comparison...
Southern Beaufort Sea Female Polar Bear Blood-Based Analyte Data, 1982-1985 Southern Beaufort Sea Female Polar Bear Blood-Based Analyte Data, 1982-1985
This dataset is one table with data collected and derived from female polar bears sampled in Alaska's southern Beaufort Sea during 1982-1985. Collected data includes demographic information. Derived data includes blood-based analyte values determined from serum samples. Serum samples were analyzed in 1986 by Evergreen Professional Services (Bothell, WA, USA). It is believed that a...
Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska
Loess is the most widespread surficial deposit in the state of Alaska. Although loess of last-glacial age is common in mid-continental North America, records of last-glacial loess in Alaska have been elusive. Here we report a record of last-glacial loess on the Seward Peninsula, along with studies of a transect of loess localities also thought to date to the last glacial period. Highly...
