Status of the National Water Data Exchange (NAWDEX) - September 1977
Melvin D. Edwards
1978, Open-File Report 78-154
Major progress in the implementation of the National Water Data Exchange (Nawdex) took place during Fiscal Year 1977--beginning October 1, 1976 and ending September 30, 1977. This report describes the status of the program at the end of this period. Program advancement is reported in the areas of administration, membership,...
Research and development program for outer continental shelf oil and gas operations, report for fiscal year 1978
John B. Gregory
1978, Open-File Report 78-902
This report summarizes the contract research program in support of the Geological Survey's Outer Continental Shelf oil and gas operations. The program is technological, though certain environmental investigations are being conducted as a necessary adjunct. The program manager provides a focal point for communicating with the research community in both...
Ground-water resources of the Cape Lookout National Seashore, North Carolina
M. D. Winner Jr.
1978, Water-Resources Investigations Report 78-52
Fresh groundwater in the Cape Lookout National Seashore in North Carolina occurs in the unconfined aquifer, an upper confined aquifer, and a lower limestome aquifer. The unconfined aquifer beneath dunes on the barrier islands is estimated to yield as much as 30 gallons per minute of freshwater to a horizontal...
Hydrogeology of the karst of Puerto Rico
Ennio V. Giusti
1978, Professional Paper 1012
About one-fifth of Puerto Rico is covered by a tropical karst formed on a series of six limestone formations ranging in age from middle-Oligocene to middle Miocene. These formations strike east to west and crop out over the north coast of the island. Structurally, the rocks form a simple wedge...
Water resources data, Nevada, water years 1977
Water Resources Division, U.S. Geological Survey
1978, Water Data Report NV-77-1
Water resources data for the 1977 water year for Nevada consist of records of discharge and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 120 gaging stations; stage and contents for 20 lakes and...
Reconstruction of crustal blocks of California on the basis of initial strontium isotopic compositions of Mesozoic granitic rocks
Ronald Wayne Kistler, Zell E. Peterman
1978, Professional Paper 1071
Initial 87Sr/ 86 Sr was determined for samples of Mesozoic granitic rocks in the vicinity of the Garlock fault zone in California. These data along with similar data from the Sierra Nevada and along the San Andreas fault system permit a reconstruction of basement rocks offset by the Cenozoic lateral...
Evaluation of the geologic and hydrologic factors related to the waste-storage potential of Mesozoic aquifers in the southern part of the Atlantic Coastal Plain, South Carolina and Georgia
Philip M. Brown, D.L. Brown, M.S. Reid, O. B. Lloyd Jr.
1978, Open-File Report 78-292
This report describes the subsurface distribution of rocks of Cretaceous to Late Jurassic(?) age in the Atlantic. Coastal Plain, South Carolina and Georgia, and examines their potential for deep-well waste storage. For mapping purposes a waste-storage "operational unit" is established and defined. It is a sand or sandstone layer, 20...
