Digital Elevation Model Hillshade

Bathymetric, topographic, and grain-size data were collected in April 2011 along a 27-mi (43.5 – km) reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach begins at river mile 61.1, about 0.6 -mi (1 –km) above the confluence of the Colorado and Little Colorado Rivers and ends at river mile 88.1 at the upstream boundary of the Bright Angel Rapid (Phantom Ranch boat beach). Channel bathymetry was mapped using multibeam and singlebeam echosounders, subaerial topography was mapped using ground-based total-stations, and bed-sediment grain-size data were collected using an underwater digital microscope system. These data were combined to produce digital elevation models, spatially variable estimates of digital elevation model uncertainty, georeferenced grain-size data, and bed-sediment distribution maps. These data were created by the Southwest Biological Science Center, Grand Canyon Monitoring and Science Center as a component of a larger effort to monitor the status and trends of sand storage along the Colorado River in Grand Canyon National Park. This dataset is the hillshade generated from the 1-meter resolution digital elevation model (DEM_EGC_Apr2011.tif) associated with this data release.

The absolute and relative composition of Holocene reef cores collected between 1976 and 2017 from the Florida Keys reef tract

This data release provides a summary of the absolute percent composition of all recovered material and relative percent composition of coral taxa in the Holocene-aged intervals of 61 coral-reef cores collected throughout the Florida Keys reef tract (FKRT) housed in the USGS Core Archive in St. Petersburg, FL (Estimated ages for distinct depths within each core are also provided; those ages were either measured by radiometric dating of coral samples at those depths or estimated by linear interpolation between measured ages. A complete dataset of all measured ages in the cores is available at https://doi.org/10.5066/F7NV9HJX (Toth and others, 2018).Estimated paleodepths of the equivalent depths observed in the coral cores acquired from 1976 to 2017 were determined by extracting the relative sea level (RSL) for each age in the cores from the model of Holocene RSL in south Florida developed by Khan and others (2017). For further information regarding data collection and analysis methods refer to the associated journal article (Toth and others, 2019). This research is a part of the U.S. Geological Survey (USGS) Coral Reef Ecosystem Studies Project (https://coastal.er.usgs.gov/crest/).

Data release of Three-Dimensional Hydrogeologic Framework Model of the Rio Grande Transboundary Region of New Mexico and Texas, USA and Northern Chihuahua, Mexico

This digital dataset represents the three-dimensional hydrogeologic framework for the Rio Grande Transboundary region of New Mexico, Texas, USA, and Northern Chihuahua, Mexico. The data define the elevation, thickness, extent, and character of the principal hydrostratigraphic units of the region, and faults and igneous intrusive dikes that cut these units. The digital data describe the following five hydrostratigraphic units: RC, river channel alluvium; three informal subdivisions of the Santa Fe Group (USF, Upper Santa Fe Group; MSF, Middle Santa Fe Group; LSF, Lower Santa Fe Group); and BSMT, which includes all pre-Santa Fe Group rocks (basement). All units except BSMT (RC, USF, MSF, LSF) are split into two subunits. In each case, the designation 1 (e.g., USF1) indicates the UPPER subunit and the designation 2 (e.g., USF2) indicates the LOWER subunit.
Most of the three-dimensional hydrogeologic framework data are contained within a single polygon feature class Frmwk_cells, which contains a mesh of polygons that represent model cells that have multiple attributes including X, Y, elevation and thickness of each hydrostratigraphic unit or subunit, and codes that represent sedimentary facies for each hydrostratigraphic subunit. The spatial extent of RC, USF, MSF, and LSF are provided as separate polygon feature classes. Faults and igneous intrusive dikes are provided as separate line features classes.
This digital dataset was created as part of a U.S. Geological Survey study, done in cooperation with the U.S. Bureau of Reclamation, to be used as the digital hydrogeologic input data for numerical simulation of the groundwater system of the Rio Grande transboundary region of New Mexico, Texas, USA and Northern Chihuahua, Mexico. These data are intended as the digital hydrogeologic input for numerical simulation of the groundwater system. Elevation, thickness, and extent of the hydrostratigraphic units define the geohydrologic layering of the digital framework model. Codes that represent sedimentary facies may be used as a lithologic basis for the distribution of hydraulic properties within each hydrostratigraphic unit. The location of faults and igneous intrusive dikes may be used to define the location of potential horizontal flow barriers in numerical simulation of the groundwater system.

Geochemical and spectroscopic data on outcrop samples from the informal Uteland Butte member of the Eocene Green River Formation in Uinta Basin, Utah

The informal Uteland Butte member of the Eocene Green River Formation in the Uinta Basin, Utah is one of the few examples of a continuous petroleum resource play in the world situated in a lacustrine sedimentary basin (Johnson and others, 2015; Birdwell and others, 2016). The datasets compiled here were collected on outcrop samples of the Uteland Butte member with the purpose of better characterizing the geochemical and mineralogical properties and variability through this unit, which represents a period of freshwater conditions in Eocene Lake Uinta in the Uinta Basin. The data have been integrated with outcrop descriptions, geophysical (gamma ray) logs, and interpretations of depositional conditions across geographic and stratigraphic trends as part of a publication (Gall et al., 2022) developed in collaboration with the Utah Geological Survey.

Estimated crop irrigation water use withdrawals in San Simon Valley Subbasin of the Safford Groundwater Basin Groundwater Basin, Arizona for 2023

Observations of irrigated agricultural land within the San Simon Valley Groundwater Subbasin of the Safford Groundwater Basin in Arizona. Crops were verified in situ twice in 2023, first on May 4th and again on Aug 15th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agriculture Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with the Sentinel2 imagery collection accessed via the European Space Agency, Copernicus Browser (https://browser.dataspace.copernicus.eu/). Satellite images were also used to identify the length of the growing season and crop condition. Water withdrawals were calculated using the modified Blaney-Criddle model of calculating consumptive use (U.S. Bureau of Reclamation, 1992 appendix A) using crop coefficients from Doorenbos and Pruitt (1975), the number of acres with active crops, crop condition, and irrigation system efficiency. The withdrawal equation was modified from "Water withdrawals for irrigation, municipal, mining, thermoelectric-power, and drainage uses in Arizona outside of active management areas, 1991-2000" (Tadayon, 2005) to account for variations in water application.

Hydrogeologic framework top-surface altitude rasters for the Virginia Eastern Shore

In support of a groundwater-flow model of the Virginia Eastern Shore, altitudes were determined for the tops of hydrogeologic surfaces, including incised paleochannel surfaces, that compose the framework within the model area. Rasters were generated from the altitude data for the tops of the surficial aquifer, upper confining unit, upper aquifer, middle confining unit, middle aquifer, lower confining unit, lower aquifer, Saint Marys confining unit, paleochannel upper aquifer, paleochannel confining unit, and paleochannel lower aquifer (McFarland and Beach, 2019; McFarland, 2019). 
This data release includes the 11 rasters mentioned above for the Virginia Eastern Shore, in tiff format. Altitude contours from existing shapefiles in McFarland (2019) and Andreasen and others (2013) were the primary sources for unit top altitudes represented by the rasters.  In the northern part of the study area, the surface altitude contours from Andreasen and others (2013) were used to supplement the contours from McFarland (2019). Topobathymetric data (Faunce and Rapp, 2020) were the source for development of the raster representing the top of the surficial aquifer.

Baseline for the South Carolina coastal region, generated to calculate shoreline change rates using the Digital Shoreline Analysis System version 5.1

The U.S. Geological Survey (USGS) has compiled national shoreline data for more than 20 years to document coastal change and serve the needs of research, management, and the public. Maintaining a record of historical shoreline positions is an effective method to monitor national shoreline evolution over time, enabling scientists to identify areas most susceptible to erosion or accretion. These data can help coastal managers and planners understand which areas of the coast are vulnerable to change. 
This data release includes two new mean high water (MHW) shorelines extracted from lidar data collected in 2010 and 2017-2018. Previously published historical shorelines for South Carolina (Kratzmann and others, 2017) were combined with the new lidar shorelines to calculate long-term (up to 166 years) and short-term (up to 18 years) rates of change. Files associated with the long-term and short-term rates are appended with "LT" and "ST", respectively. A proxy-datum bias reference line that accounts for the positional difference in a proxy shoreline (e.g. High Water Line (HWL) shoreline) and a datum shoreline (e.g. MHW shoreline) is also included in this release.

Milwaukee Metropolitan Sewerage District nutrient connections project—In-stream nutrient cycling, 2022 data

Understanding sediment nutrient dynamics in the Milwaukee River Basin is important for assessing water quality and stream habitat. The Milwaukee River is a major tributary to Lake Michigan that provides clean drinking water for over one million people. Urban and agricultural runoff are linked to elevated loads of phosphorus, nitrogen, and sediment in the river. Excessive nutrients can impair water quality and cause excessive phytoplankton and cyanobacteria growth which in-turn can reduce oxygen levels affecting invertebrates and fish, as well as produce toxins harmful to humans and aquatic organisms. In-stream nutrient cycling can lower water column nutrient concentrations and improve water quality; stream sediments can store phosphorus long term and remove nitrogen permanently through microbially-mediated denitrification. However, stream sediments may also release phosphorus to the water column if they are saturated with phosphorus. This study quantified rates of biogeochemical processes in 24 sites within the Milwaukee River Basin and 8 sites outside the Milwaukee River Basin but within the Milwaukee River metropolitan area. Data from this study will provide baseline information about sediment nutrient dynamics in the Milwaukee River Basin and help assess the effectiveness of stream rehabilitation to retain phosphorus and remove nitrogen prior to the water reaching Lake Michigan.
