Hydrogeologic framework bottom elevations and thicknesses of Permian, Upper Pennsylvanian, Lower Pennsylvanian, and Mississippian units in the Appalachian Plateaus Physiographic Province

As part of the U.S. Geological Survey Water Availability and Use Science Program study of Appalachian Plateaus aquifers, bottom elevations and thicknesses were determined for Permian, Upper Pennsylvanian, Lower Pennsylvanian, and Mississippian hydrogeologic framework units in the Appalachian Plateaus, covering parts of Pennsylvania, Maryland, Ohio, West Virginia, Kentucky, Virginia, Tennessee, Georgia, and Alabama. Thickness values for these units were compiled at point locations from available sources (Martens, 1945; McKee and Crosby, 1975; Craig and Connor, 1979; Ryder and others, 2008, 2009, 2012, 2015) and used to interpolate surfaces representing thicknesses, contact elevations, and outcrop elevations using...

Mean-annual and mean-seasonal water-budget estimates from a Soil-Water-Balance model of the Appalachian Plateaus, 1980 through 2011

As part of the U.S. Geological Survey Groundwater Resources Program study of Appalachian Plateaus aquifers, mean-annual and mean-seasonal water-budget estimates for the period 1980 through 2011 were determined for a 162,000 square-mile area covering parts of New York, Pennsylvania, Maryland, Ohio, West Virginia, Kentucky, Virginia, Tennessee, North Carolina, Georgia, Alabama, and Mississippi. Mean-annual and mean-seasonal precipitation, recharge, and actual evapotranspiration (ET) estimates were derived from annual and monthly Soil-Water-Balance (SWB) model (McCoy and others, 2015; Westenbroek and others, 2010) output and compiled in a geodatabase. Precipitation estimates from the Appalachian Plateaus SWB model...

Geodatabase of the datasets used to represent the two subunits of the Pennsylvanian aquifer in the Lower Peninsula of Michigan

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This geodatabase includes spatial datasets that represent the Pennsylvanian aquifers in the Lower Peninsula of Michigan. Included are: (1) polygon extents; datasets that represent the entire aquifer extent in the States of Alabama, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia; the entire extent subdivided into subareas or subunits where data exist (Lower Peninsula...
