A digital model of the sedimentary Northern Atlantic Coastal Plain aquifer system is composed of 20 rasters and hydrogeologic unit extent polygons. Rasters describe the top elevations of regional aquifers and confining units at a resolution of 2640 feet (1/2 mile). The rasters are clipped to the extent polygons, which represent the spatial extents of the hydrogeologic units onshore and several miles offshore. This three-dimensional hydrogeologic model was constructed as part of a U.S. Geological Survey Groundwater Resources Program study of groundwater availability in the Northern Atlantic Coastal Plain (NACP) aquifer system, including parts of New York, New Jersey, Delaware, Maryland, Virginia, and North Carolina....

This release contains geophysical data from the Kuparuk aufeis associated with the manuscript "Seasonal thaw dynamics of an aufeis feature inferred from surface geophysical methods." Data were collected in two campaigns in September 2016 and April 2017 with the purpose of investigating freeze-thaw dynamics below the aufeis feature during maximally frozen and maximally thawed conditions. Ground penetrating radar common offset data from both campaigns (160MHz and 80MHz) is presented, including interpreted depths to interfaces (permafrost, ice-frozen ground interface, and talik surface). Surface nuclear magnetic resonance data and inverse results are also included from April 2017 as well as interpreted talik thicknesses....
This dataset includes example data used for demonstration of the moisturEC program. This includes inverted electrical resistivity data, model resolution from the inversion, point moisture information, and conductivity-saturation calibration information. The data are from a field site in Coventry, CT outfitted with five, Decagon 5TE moisture probes, arranged along a 28 m transect at different depths. The data represent a slice in time after irrigating the soil for 12 hours.

Three streamflow measurements are used to demonstrate the use of equations developed in Mueller (in review). All three measurements are from various locations on the Mississippi River. These data were not collected for the purpose of this paper but provide practical examples of the effect of heading errors. The use of data from the Mississippi River allows the collection of 500 or more ensembles in each transect which reduce the overall effect of random errors that could complicate the identification of effects due to heading errors. In addition, by using wide cross sections, the effect of GPS errors due to vegetation near the boundaries of the river are minimized. All measurements were collected with WinRiver II...
