Loch Vale Watershed hydroclimate and isotopes of tree-ring cellulose and source-water isotope model Loch Vale Watershed hydroclimate and isotopes of tree-ring cellulose and source-water isotope model
Stable isotopes of water preserved in geologic archives, primarily as oxygen (d18O), have proven critical for documenting Earth’s climatic and hydrologic systems past and present. However, timescale differences of water isotope inputs to proxy systems and the signal embedded in long paleorecords often confound translation to observed hydroclimatic metrics. Here, a unique 20-year dataset...
Lake Michigan Gillnet Lake Trout Assessment 1998-2003 Lake Michigan Gillnet Lake Trout Assessment 1998-2003
Annual spring (May) and fall (late October through early November) gillnet assessment surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in northern Lake Michigan, including the Northern Refuge, between 1998-2023. Total length, weight, sex, maturity, and sea lamprey wounds were recorded for each lake trout and burbot caught in the gill nets. Lake trout...
Petrogenic organic carbon estimates for two Rocky Mountain soils underlain by Cretaceous Mancos Shale Petrogenic organic carbon estimates for two Rocky Mountain soils underlain by Cretaceous Mancos Shale
This dataset contains sample collection details, analytical measurements of carbon content, and estimated petrogenic carbon contents of soil samples and shale samples collected from two locations in the Colorado Rocky Mountains.
Lake Erie Fish Community Data, 2013-2023 Lake Erie Fish Community Data, 2013-2023
Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management, the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western...
Total organic carbon, programmed temperature pyrolysis, vitrinite reflectance, organic carbon isotopes, elemental, and spectral gamma-ray data from the Cretaceous Hue Shale (Jago River outcrop), Arctic Alaska, USA Total organic carbon, programmed temperature pyrolysis, vitrinite reflectance, organic carbon isotopes, elemental, and spectral gamma-ray data from the Cretaceous Hue Shale (Jago River outcrop), Arctic Alaska, USA
Chemostratigraphic signatures were recorded in a 113 m thick outcrop of late Albian to early Campanian (~103–82 Ma) Hue Shale exposed on the bank of the Jago River in the coastal plain (“1002 Area”) of the Arctic National Wildlife Refuge (ANWR), Alaska. Spectral gamma-ray (SGR) data was collected in situ across the Jago River section. A total of 250 samples consisting of predominantly...
Monthly ensemble outputs from the National Hydrologic Model Precipitation-Runoff Modeling System and the Weather Research and Forecasting model hydrologic modeling system for the conterminous United States, Alaska, Hawaii, and Puerto Rico for water years Monthly ensemble outputs from the National Hydrologic Model Precipitation-Runoff Modeling System and the Weather Research and Forecasting model hydrologic modeling system for the conterminous United States, Alaska, Hawaii, and Puerto Rico for water years
The Integrated Water Availability Assessment uses an ensemble of outputs from two hydrologic models to assess water supply conditions. Results from the two models, the National Hydrologic Model Precipitation-Runoff Modeling System (NHM-PRMS) and Weather Research and Forecasting model hydrologic modeling system (WRF-Hydro) were averaged to create a single model ensemble. A unique instance...
