Thin section images, automated mineralogy scans, lithogeochemistry, and Nd-Sr-Pb isotopic analysis of samples from a mostly buried layered mafic intrusion, Wet Mountains, Colorado 2022-2024 Thin section images, automated mineralogy scans, lithogeochemistry, and Nd-Sr-Pb isotopic analysis of samples from a mostly buried layered mafic intrusion, Wet Mountains, Colorado 2022-2024
This dataset includes thin section images, automated mineralogy mineral maps, whole-rock geochemical data, and whole-rock Nd-Sr-Pb isotopic analysis of samples collected from nine mafic-ultramafic outcrops in the Wet Mountains, southern Colorado, during the summer of 2022. These data will accompany an upcoming journal publication and are intended to supplement recently collected airborne...
Eelgrass (Zostera marina) Maps from 2016 and 2020, Izembek Lagoon, Alaska Eelgrass (Zostera marina) Maps from 2016 and 2020, Izembek Lagoon, Alaska
This data package includes 40 geospatial rasters (maps) depicting various metrics about eelgrass (Zostera marina) coverage at Izembek Lagoon, Alaska, during 2016 and 2020. Two maps were produced from two Sentinel-2 satellite images collected on July 1, 2016, and August 14, 2020. Spectral classes derived from each satellite image were annotated and mapped based on data collected in the...
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...
