Borehole geologic-unit top-surface altitude and aquifer-component test data for the Piney Point aquifer, Virginia from 2009 through 2015
This USGS data release contains (1) geologic-unit top-surface altitudes in boreholes and (2) aquifer-test time-series water-level drawdowns, recoveries, and supporting data from the Piney Point aquifer in Virginia from 2009 through 2015. Extents, compositions, configurations, and geologic relations of six geologic units that compose the Piney Point aquifer were determined from geologists logs of s
Geochemical Data Release for Gospel-Hump Wilderness Area, Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana
The data release for Gospel-Hump Wilderness Area and the Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana, contains a subset of previously unpublished geochemical data from the 1979-1984 projects. In the case of Gospel-Hump Wilderness Area study (Lund and Esparza, 1990), the purpose of the pr
Bedrock well yield, lineaments, and ancillary data in the Nashoba Terrane, central and eastern Massachusetts
This data release contains well yield and ancillary data for 7,287 bedrock wells used in an analysis of bedrock well yield in the Nashoba Terrane and surrounding area in eastern and central Massachusetts. The data release also contains Geographic Information System (GIS) data layers of lineaments delineated from aerial photographs and digital elevation data for a part of the Nashoba Terrane study
EAARL Coastal Topography-Eastern Louisiana Barrier Islands, 09 March 2008
These datasets, prepared cooperatively by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center and the National Park Service (NPS), provide lidar-derived first-surface and bare-earth topography for a portion of eastern Louisiana. Elevation measurements were acquired by the Experimental Advanced Airborne Research Lidar (EAARL) on March 9, 2008.
Post Hurricane Sandy Beach Profile Survey-Fire Island Inlet to Moriches Inlet 2013
The U.S. Army Corps of Engineers contracted a beach survey of Fire Island, New York from September 17-October 6, 2013 for the purpose of planning of a beach reconstruction project following Hurricane Sandy. This dataset contains elevation data of subaerial morphology and nearshore bathymetry collected using real time kinematic global positioning system (RTK-GPS) and hydrography techniques. The dat
Ground-based lidar beach topography of Fire Island, New York, January 2012
The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS-SPCMSC) and the U.S. Army Corps of Engineers Field Research Facility (USACE-FRF) of Duck, NC collaborated to gather alongshore ground-based lidar beach topography at Fire Island, NY. This high-resolution elevation dataset was collected on January 30, 2012 and extends along 31 kilometers (km) of Fire Island, NY beach
Summary Statistics Data for Greater Sage-Grouse (Centrocercus urophasianus) Nesting and Brood-Rearing Microhabitat in Nevada and California-Spatial Variation in Selection and Survival Patterns, 2009-16
This dataset provides summary statistics of multiple sage-grouse microhabitat characteristics of the Great Basin.
These data support the following publication: Coates, P.S., Brussee, B.E., Ricca, M.A., Dudko, J.E., Prochazka, B.G., Espinosa, S.P., Casazza, M.L., and Delehanty, D.J., 2017, Greater sage-grouse (Centrocercus urophasianus) nesting and brood-rearing microhabitat in Nevada and Califo
Geospatial data for Luquillo Mountains, Puerto Rico: Mean annual precipitation, elevation, watershed outlines, and rain gage locations
These geospatial data sets were developed as part of a new analysis of all known current and historical rain gages in the Luquillo Mountains, Puerto Rico published in the journal article Murphy, S.F., Stallard, R.F., Scholl, M.A., Gonzalez, G., and Torres-Sanchez, A.J., 2017, Reassessing rainfall in the Luquillo Mountains, Puerto Rico: Local and global ecohydrological implications: PLOS One 12(7):
Channel Cross-section Data for Powder River between Moorhead and Broadus, Montana from 1975 to 2016
This data release consist of 34 channel cross sections of Powder River measured from 1975 through 2016 along a 90-kilometer reach from Moorhead to Broadus, Montana. Most channel cross sections were measured annually from 1975 through 1998 and then intermittently through 2016. In 1978, after all cross sections had been established, there was a extreme flood with an approximate 50-year recurrence in
Streamflow statistics calculated from daily mean streamflow data collected during water years 19012015 for selected U.S. Geological Survey streamgages
In 2016, non-interpretive streamflow statistics were compiled for streamgages located throughout the Nation and stored in the StreamStatsDB database for use with StreamStats and other applications. Two previously published USGS computer programs that were designed to help calculate streamflow statistics were updated to better support StreamStats as part of this effort. These programs are named GNW
Estimated county level domestic well population with arsenic greater than 10 micrograms per liter based on probability estimates for the conterminous U.S.
Arsenic concentrations from 20,450 domestic wells in the U.S. were used to develop a logistic regression model of the probability of having arsenic > 10 g/L (high arsenic). We use only domestic well arsenic data and a national-scale modeling approach. This approach expands our understanding of potential exposure to arsenic in drinking water to a national scale and allows inter-regional comparisons
