Elevation change in the watershed of Rito de los Frijoles, Bandelier National Monument, New Mexico from 2010 to 2016 Elevation change in the watershed of Rito de los Frijoles, Bandelier National Monument, New Mexico from 2010 to 2016
Intense precipitation following the June 2011 Las Conchas Fire in the Jemez Mountains, New Mexico, led to widespread debris flows in the watershed of Rito de los Frijoles in Bandelier National Monument. Sediment eroded by these debris flows was transported along Rito de los Frijoles during floods in 2011 and 2013. This dataset contains two tabular files and one raster digital file. The...
GIS shapefile and summary tables of the extent of irrigated agricultural land use for 11 counties fully or partially within the St. Johns River Water Management District Florida, 2022–23 GIS shapefile and summary tables of the extent of irrigated agricultural land use for 11 counties fully or partially within the St. Johns River Water Management District Florida, 2022–23
A Geographic Information System shapefile and summary tables of the extent of irrigated agricultural land-use are provided for eleven counties fully or partially within the St. Johns River Water Management District (full-county extents of: Brevard, Clay, Duval, Flagler, Indian River, Nassau, Osceola, Putnam, Seminole, St. Johns, and Volusia counties). These files were compiled through a
Data and rloadest models used to estimate sediment and nutrient loads in selected New York tributaries to eastern Lake Erie Data and rloadest models used to estimate sediment and nutrient loads in selected New York tributaries to eastern Lake Erie
This data release contains data and rloadest models used to estimate sediment and nutrient loads in selected New York tributaries to eastern Lake Erie. Load estimates for suspended sediment and nutrients were calculated using rloadest (Lorenz and others, 2013; Runkel and De Cicco, 2017) models. Included are a zip file with input and output files for selected rloadest models for 13 U.S...
Concentrations of 1,4-Dioxane, Per- and Polyfluorinated Substances (PFAS), Chlorofluorocarbons (CFCs), Methyl Tert-Butyl Ether (MTBE), and Trihalomethanes (THMs) in Groundwater, Nassau County, New York, 2019-2022 Concentrations of 1,4-Dioxane, Per- and Polyfluorinated Substances (PFAS), Chlorofluorocarbons (CFCs), Methyl Tert-Butyl Ether (MTBE), and Trihalomethanes (THMs) in Groundwater, Nassau County, New York, 2019-2022
This data release contains 1-4 dioxane, per- and polyfluoroalkyl substances (PFAS), chlorofluorocarbons (CFCs), methyl tert-butyl ether (MTBE), and trihalomethanes (THMs) concentration data from groundwater samples collected from 78 monitoring wells in Nassau County New York. Samples were collected from May 2019 through December 2022 at wells ranging in depth from twenty-three feet to...
Broadband Ground Motion Simulations for an Earthquake “Doublet” on the Hayward and Calaveras Faults Broadband Ground Motion Simulations for an Earthquake “Doublet” on the Hayward and Calaveras Faults
The occurrence and impact of the February 2023 earthquake doublet in Türkiye, where an Mw 7.8 event was followed roughly 9 hours later by an Mw 7.5 event on an adjacent fault, begs the question: What would be the impact of such a sequence in California? As part of the effort to address this question, this Data Release consists of simulated ground motions for a hypothetical doublet...
Martian Frost Observations from Gullied Locations Derived from 2006-2015 HiRISE Images Martian Frost Observations from Gullied Locations Derived from 2006-2015 HiRISE Images
These data describe observations of frost and related features in alcoves and slopes near Martian gully landforms. The base data are images from the High Resolution Imaging Science Experiment (HiRISE) acquired prior to Ls=0 of Mars Year 33 (June 18, 2015).
