Publication Extents

Not all publications have extents, not all extents are completely accurate
Publication search and retrieval system
Elizabeth A. Winget
1981, Open-File Report 81-1096
The publication search and retrieval system of the Branch of Atlantic-Gulf of Mexico Geology, U.S. Geological Survey, Woods Hole, Mass., is a procedure for listing and describing branch-sponsored publications. It is designed for maintenance and retrieval by those having limited knowledge of computer languages and programs. Because this branch currently...
Proposed observation-well network and ground-water level program for North Carolina
M. D. Winner Jr.
1981, Open-File Report 81-544
An initial system of 223 observation wells is proposed for monitoring ground-water levels in North Carolina. These wells are suggested to replace and upgrade nearly 650 observation wells currently measured in separate State and Federal programs, and are arranged in four groups or networks each having specific objectives. These groups...
Documentation of a dissolved-solids model of the Tongue River, southeastern Montana
Paul F. Woods
1981, Open-File Report 81-479
A model has been developed for assessing potential increases in dissolved solids of the Tongue River as a result of leaching of overburden materials used to backfill pits in surface coal-mining operations. The model allows spatial and temporal simulation of streamflow and dissolved-solids loads and concentrations under user-defined scenarios of...
Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1979
C.M. Wood, H.S. Butler, J.D. Benton
1981, Open-File Report 81-491
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Houston, and San Antonio. The study for the Fort Worth metropolitan area was completed at the end of the 1978 water year, and this report is...
Proceedings of a workshop on clathrates (gas hydrates) in the National Petroleum Reserve in Alaska, July 16-17, 1979, Menlo Park, California
Arthur Leroy Bowsher, editor(s)
1981, Open-File Report 81-1298
Purpose: The purpose of this report is to make available the results of the "Workshop on clathrates (gas hydrates) in the National Petroleum Reserve in Alaska," July 16-17, 1979, Menlo Park, California.Scope: Written reports presented by participants of the workshop, relevant letters generated by this workshop and some "forms" created...
Mathematical model of gamma-ray spectrometry borehole logging for quantitative analysis
Ulrich Schimschal
1981, Open-File Report 81-402
A technique for analyzing gamma-ray spectral-logging data has been developed, in which a digital computer is used to calculate the effects of gamma-ray attentuation in a borehole environment. The computer model allows for the calculation of the effects of lithology, porosity, density, and the thickness of a horizontal layer of...
Description and preliminary interpretation of core CL-80-1, Clear Lake, Lake County, California
John D. Sims, Michael J. Rymer, James A. Perkins
1981, Open-File Report 81-751
Coring operations were conducted in the west basin of Clear Lake during July and August 1980 to produce a regional Quaternary reference section. A 177-m-long core (CL-80-1) was taken, which also augments and extends a previous study of eight shorter cores collected from Clear Lake in 1973. Core CL-80-1 was...
