Sediment grain-size distributions, stable carbon isotope ratios (d13C), total carbon to total nitrogen ratios (C:N), short-lived radionuclides (Beryllium-7, Cesium-137, and Lead-210), concentrations of 76 parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and concentrations of 33 per- and polyfluoroalkyl substances (PFAS) were measured in the northern reach of San Francisco Bay...
Drainage-basin characteristics associated with road and stream intersections in Montana Drainage-basin characteristics associated with road and stream intersections in Montana
This data release presents drainage-basin characteristics for 12,639 road and stream intersections in Montana. The drainage-basin characteristics presented include those computed by the Montana StreamStats application (McCarthy and others, 2016). Statistical analysis of the road and stream intersections was included in the report "Peak-Flow Variability, Peak-Flow Informational Needs, and
Table of Electron Probe Microanalyses of Native Copper and Sulfide Minerals from the White Pine Sediment-hosted Copper Deposit, Michigan Table of Electron Probe Microanalyses of Native Copper and Sulfide Minerals from the White Pine Sediment-hosted Copper Deposit, Michigan
This data release provides electron microprobe geochemical data that was collected as part of a scoping study to evaluate whether unconventional critical element resources may be associated with sediment-hosted copper systems in the Midcontinent Rift. We report abundances of trace elements in native copper and sulfide minerals in 12 thin sections from samples of the Mesoproterozoic lower...
Field data from brief aquifer tests of domestic wells penetrating bedrock in the Appalachian Plateau of New York and best fits to theoretical curves of aquifer properties Field data from brief aquifer tests of domestic wells penetrating bedrock in the Appalachian Plateau of New York and best fits to theoretical curves of aquifer properties
This data release contains observed water-level recovery data in 52 wells, matched to theoretical type curves defined by postulated values of aquifer transmissivity and storage, that together constitute the database for USGS Scientific Investigations Report 2020-5087, "Transmissivity Estimated from Brief Aquifer Tests of Domestic Wells and Compared with Bedrock Lithofacies and Position...
Geochemical analyses of rock samples collected from the Dotson and I and L rare earth element deposits of the Bokan Mountain peralkaline igneous complex, Prince of Wales Island, southeastern Alaska Geochemical analyses of rock samples collected from the Dotson and I and L rare earth element deposits of the Bokan Mountain peralkaline igneous complex, Prince of Wales Island, southeastern Alaska
This data release presents the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) from trenches, channel cuts, test pits, and surface exposures of the Dotson and I and L Zone rare earth element deposits at Bokan Mountain, located in the southern part of Prince of Wales Island, southeastern Alaska. Bokan Mountain was formed by an Early...
Digital Datasets for the Hydrogeology of the Susquehanna River Valley in South-Central Broome County, Towns of Conklin and Kirkwood, New York Digital Datasets for the Hydrogeology of the Susquehanna River Valley in South-Central Broome County, Towns of Conklin and Kirkwood, New York
The U.S. Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), collected and compiled well records to characterize the valley-fill aquifers of south-central Broome County beginning in 2014. The study area is defined by the limits of the Binghamton East quadrangle, which encompasses 55.5 square-miles (mi^2), and includes a 9...
MODFLOW 6 model of two hypothetical stream-aquifer systems to demonstrate the utility of the new Mover Package available only with MODFLOW 6 MODFLOW 6 model of two hypothetical stream-aquifer systems to demonstrate the utility of the new Mover Package available only with MODFLOW 6
Two MODFLOW 6 (version 6.2.1) models of hypothetical stream-aquifer systems are presented for the demonstration and utility of the Water Mover (MVR) Package available only with MODFLOW 6. Using a generalized approach, MVR facilitates the transfer of water among many arbitrary combinations of simulated features (i.e., pumping wells, stream, drains, lakes, etc.) within a MODFLOW 6...
Soil-Water-Balance (SWB) model data sets for the Greater Wake County area, North Carolina, 1981 - 2070 Soil-Water-Balance (SWB) model data sets for the Greater Wake County area, North Carolina, 1981 - 2070
This data release has been deprecated. The new version can be found at https://doi.org/10.5066/P95XKK5V. A Soil-Water-Balance (SWB) model was developed to estimate annual net infiltration below the root-zone for the Greater Wake County Area, North Carolina for the period 1981 through 2019 and project future estimates from 2020 through 2070. The model was developed as part of a study to...
Shorelines from High-resolution WorldView Satellite Imagery, Real-time Kinematic Global Positioning Data, and Aerial Imagery for 2013 to 2020 for Study Sites Within Grand Bay National Estuarine Research Reserve, Mississippi Shorelines from High-resolution WorldView Satellite Imagery, Real-time Kinematic Global Positioning Data, and Aerial Imagery for 2013 to 2020 for Study Sites Within Grand Bay National Estuarine Research Reserve, Mississippi
Shoreline change analysis is an important environmental monitoring tool for evaluating coastal exposure to erosion hazards, particularly for vulnerable habitats such as coastal wetlands where habitat loss is problematic world-wide. The increasing availability of high-resolution satellite imagery and emerging developments in analysis techniques support the implementation of these data...
MODFLOW-NWT and MODPATH6 model use to analyze remedial scenarios affecting plume movement through a sole-source aquifer system, southeastern Nassau County, New York MODFLOW-NWT and MODPATH6 model use to analyze remedial scenarios affecting plume movement through a sole-source aquifer system, southeastern Nassau County, New York
A three-dimensional steady-state groundwater flow model is coupled with the particle-tracking program, MODPATH, to assess the fate and transport of volatile organic compound plumes within the Magothy and upper glacial aquifers in southeastern Nassau County, NY. Knowledge of groundwater-flow patterns and rates is essential for effective management of groundwater resources and for...
MODFLOW-NWT and MODPATH6 Used to Delineate Areas Contributing Groundwater and Travel Times to Receiving Waters in Kings, Queens, Nassau, and Suffolk Counties, New York MODFLOW-NWT and MODPATH6 Used to Delineate Areas Contributing Groundwater and Travel Times to Receiving Waters in Kings, Queens, Nassau, and Suffolk Counties, New York
A previously developed three-dimensional steady-state groundwater flow model (https://doi.org/10.3133/sir20205091) is used to assist resource managers and planners in developing informed strategies to address nitrogen loading to coastal water bodies of Long Island, New York. Coastal water bodies of Long Island are important economic and recreational resources for the region. Therefore...
