Hydrogeology, karst, and groundwater availability of Monroe County, West Virginia
Monroe County is in southeastern West Virginia, encompassing an area of 474 square miles. The area consists of karst and siliciclastic aquifers of Ordovician, Silurian, Devonian, and Mississippian age and is in parts of two physiographic provinces: the Valley and Ridge Province to the east of Peters Mountain, and the Appalachian Plateau Province to the west of Peters Mountain. This study was develAuthorsMark D. Kozar, Daniel H. Doctor, William K. Jones, Nathan Chien, Cheyenne E. Cox, Randall C. Orndorff, David J. Weary, Mitchell R. Weaver, Mitchell A. McAdoo, Mercer ParkerGeology and biostratigraphy of the Upper Floridan aquifer in the greater Savannah region, Georgia and South Carolina
The Upper Floridan aquifer (UFA) of South Carolina, Georgia, Alabama, Mississippi, and Florida has been considered a regionally continuous stratigraphic sequence of Eocene to Miocene carbonate strata, with documented unconformities based on lithology and biostratigraphy. As part of an investigation of the regional subsurface geologic framework in the Atlantic Coastal Plain Province, three deep coAuthorsJean Self-Trail, Mercer Parker, John T. Haynes, Arthur P. Schultz, Paul. F. HuddlestonChesapeake Bay impact structure—Development of "brim" sedimentation in a multilayered marine target
The late Eocene Chesapeake Bay impact structure was formed in a multilayered target of seawater underlain sequentially by a sediment layer and a rock layer in a continental-shelf environment. Impact effects in the “brim” (annular trough) surrounding and adjacent to the transient crater, between the transient crater rim and the outer margin, primarily were limited to the target-sediment layer.

Fort Pulaski National Monument is located on Cockspur Island in Chatham County, Georgia, within the Atlantic Coastal Plain province. The island lies near the mouth of the Savannah River, and consists of small mounds (hummocks), salt marshes, and sediment dredged from the river. A 1,017-foot (ft) (310-meter [m])-deep core drilled at Cockspur Island in 2010 by the U.S. Geological Survey revealed sevAuthorsChristopher S. Swezey, Ellen Seefelt, Mercer Parker
