In 2006, a cooperative study was established to compile reliable data describing groundwater and surface-water interactions in the Elkhorn and Loup River Basins. The purpose of the study was to...
-
Water level altitudes were measured at 334 observation wells and 1 supply well screened in the upper glacial and Magothy aquifers during April and May of 2013. This shapefile consists of the...

A three-dimensional (3D) groundwater flow model of the glaciated sediments around Elkhart, Indiana was constructed as part of the U.S. Geological Survey Groundwater Resources Program using...
-
Cores collected from recent drilling in western Cape Cod, Massachusetts provide insight into the topography and petrology of the underlying bedrock. Cores from 64 drill sites spread over a...
-
Determining how much methane and carbon dioxide cross the sea-air interface is critical when assessing marine greenhouse gas fluxes. This assessment is particularly important on Arctic Ocean...
-
This digital GIS dataset and accompanying nonspatial files synthesize model outputs from a regional-scale volumetric 3D geologic model that portrays the generalized subsurface geology of the...

-
Recent studies have shown the oxygen isotopic composition (δ18O) of modern terrestrial gastropod shells is determined largely by the δ18O of precipitation. This implies that fossil shells could be...

A digital representation of a glacial aquifer map for the northeastern United States (Kontis and others, 2004; http://pubs.er.usgs.gov/publication/pp1415C; Plate 3) has been prepared by staff of...
-
Using iTOUGH2-EOS7C, a simple 1-D model was developed to represent a site in Ontario, Canada which is being considered for nuclear waste disposal. The site exhibits substantially underpressured...

The depth to water table was measured at 335 groundwater monitoring wells (observation and supply) screened in the upper glacial and Magothy aquifers during April and May of 2013. This raster data...
-
This data release consists of data (in four tables) for assessing the time scales of arsenic variability in three production wells in New Hampshire; tables that describe the data fields in the...
