U-Pb Ages, Hafnium Isotope Ratios, and Trace Element Concentrations by Laser-ablation Split Stream (LASS) Analysis of Igneous and Metamorphic Zircons from the Yukon-Tanana Upland, Eastern Alaska U-Pb Ages, Hafnium Isotope Ratios, and Trace Element Concentrations by Laser-ablation Split Stream (LASS) Analysis of Igneous and Metamorphic Zircons from the Yukon-Tanana Upland, Eastern Alaska
This dataset contains U-Pb isotopic data and ages, Hf isotope data, and trace element concentrations of zircon from igneous rocks collected from the Yukon-Tanana Upland, eastern Alaska. The sample suite was collected as part of geological mapping and supporting geochemical and geochronological analysis conducted from 2013 to 2019. Zircon was obtained from these igneous rocks to determine...
Geomorphic Habitat Response Units Attributes for the Wisconsin DNR 24k Hydrography Flowline Network in the Milwaukee River Basin, Wisconsin Geomorphic Habitat Response Units Attributes for the Wisconsin DNR 24k Hydrography Flowline Network in the Milwaukee River Basin, Wisconsin
This date release was produced as part of the Milwaukee Area Watercourse Corridor Study in partnership with the Milwaukee Metropolitan Sewerage District (MMSD) to monitor and assess stream water quality within studies of aquatic communities, geomorphology and habitat, water and sediment, and streamflow. This dataset contains two vector datasets of stream geomorphic characteristics, pre...
Survey Results for Temblor Legless Lizards (Anniella alexanderae) in the San Joaquin Valley of California, 2022 and 2023 Survey Results for Temblor Legless Lizards (Anniella alexanderae) in the San Joaquin Valley of California, 2022 and 2023
Locations of sites at which U.S. Geological Survey (USGS) biologists surveyed for Temblor legless lizards (Anniella alexanderae) in 2022 and 2023 and the results of those surveys. At the time of the species description, little was known about the distribution of the Temblor legless lizard beyond a few localities. Surveys were designed to gather information on the distribution of Temblor...
Deep-learning-derived alluvium, shallow-to-exposed bedrock, and surficial sediment thickness map for the upper Neversink River watershed, New York Deep-learning-derived alluvium, shallow-to-exposed bedrock, and surficial sediment thickness map for the upper Neversink River watershed, New York
This dataset consists of a raster and surficial shapefiles for the Neversink River watershed, NY, that were generated using ArcGIS Pro's deep learning functionality. The shapefiles contain polygons that show the locations of shallow-to-exposed bedrock and alluvium-filled valleys, while the raster provides estimated minimum sediment thicknesses in the areas between the shallow/exposed...
Soil-Water-Balance (SWB) model archive used to simulate potential annual recharge for the former Badger Army Ammunition Plant study area, Prairie du Sac, Wisconsin, 1980 to 2020 Soil-Water-Balance (SWB) model archive used to simulate potential annual recharge for the former Badger Army Ammunition Plant study area, Prairie du Sac, Wisconsin, 1980 to 2020
This model archive makes available the U.S. Geological Survey Soil-Water-Balance (SWB) model created in support of a groundwater flow model of the former Badger Army Ammunition Plant in Sauk County, Wisconsin. The SWB model provides initial estimates of potential recharge to the groundwater system in the study area, which are used in a calibrated 3-dimensional MODFLOW (modular finite...
Estimated bedload transport rates at Rio Vista and Jersey Point, California, 2011-2020 Estimated bedload transport rates at Rio Vista and Jersey Point, California, 2011-2020
This data set contains estimates of bedload transport entering San Francisco Bay from the Sacramento-San Joaquin Delta. Bedload was estimated following the methods of van Rijn (1984) for the Sacramento River at Rio Vista (USGS 11455420) and the San Joaquin River at Jersey Point (USGS 11337190). The inputs the van Rijn (1984) equations included:bed-material particle size, bed-form...
