Computer retrieval of bibliographies using an editing program
G.E. Brethauer, V.L. Brokaw
1979, Open-File Report 79-1433
A simple program permits use of the text .editor 'qedx,' part of many computer systems, to input bibliographic entries and to retrieve specific entries which contain keywords of interest. Multiple keywords may be used sequentially to find specific entries....
Assessment of geothermal resources of the United States: 1978
L.J. Patrick Muffler
1979, Circular 790
The geothermal resource assessment presented in this Circular is a refinement and updating of USGS Circular 726. Nonproprietary information available in June 1978 is used to assess geothermal energy in the ground and, when possible, to evaluate the fraction that might be recovered at the surface. Five categories of geothermal...
Status of surface-water modeling in the U.S. Geological Survey
Marshall E. Jennings, Nobuhiro Yotsukura
1979, Circular 809
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of surface-water problems. Types of problems for which models have been, or are being developed, include categories such as the following: (1)specialized hydraulics, (2)flow routing in streams, estuaries, lakes, and reservoirs,...
A methodology for post-EIS (environmental impact statement) monitoring
Linda Graves Marcus
1979, Circular 782
A methodology for monitoring the impacts predicted in environmental impact statements (EIS's) was developed using the EIS on phosphate development in southeastern Idaho as a case study. A monitoring system based on this methodology: (1) coordinates a comprehensive, intergovernmental monitoring effort; (2) documents the major impacts that result, thereby improving...
A supplement to "Methods for collection and analysis of aquatic biological and microbiological samples"
Phillip E. Greeson, editor(s)
1979, Techniques of Water-Resources Investigations 05-A4
The report contains methods used by the U.S. Geological Survey to collect, preserve, and analyze waters to determine their biological and microbiological properties. It supplements, "Methods for Collection and Analysis of Aquatic Biological and Microbiological Samples" (TWRI, Book 5, Chapter A4, 1977, edited by P. E. Greeson, T. A. Ehlke,...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Big Delta quadrangle, Alaska
Helen Laura Foster, N. R. D. Albert, Andrew Griscom, T. D. Hessin, W. D. Menzie, D. L. Turner, Frederic H. Wilson
1979, Circular 783
The geology, geochemistry, geophysics, and Landsat imagery of the Big Delta quadrangle, 16,335 km 2 in the Yukon-Tanana Upland of east-central Alaska, were investigated, and maps and reports were prepared by an interdisciplinary research team for the purpose of assessing the mineral potential. The quadrangle is dominantly a complex terrane...
The United States Geological Survey in Alaska: Accomplishments during 1978
Kathleen M. Johnson, John R. Williams, editor(s)
1979, Circular 804-B
This circular describes the 1979 programs of the U.S. Geological Survey in Alaska. The mission of the Geological Survey is to identify the Nation 's land, water, energy, and mineral resources; to classify federally-owned mineral lands and water-power sites; to resolve the exploration and development of energy and natural resources...
Initial report of the Petrophysics Laboratory
Graham R. Hunt, G. R. Johnson, G.R. Olhoeft, D.E. Watson
1979, Circular 789
Current national requirements for energy and mineral resources, and for protection of the quality of the environment, have focused attention on the need to develop new methods and interpretation techniques to be used in understanding geologic systems. Geophysical surveys play a significant role in acquiring this information, particularly by providing...
Methods for determination of inorganic substances in water and fluvial sediments
Marvin W. Skougstad, Marvin J. Fishman, Linda C. Friedman, David E. Erdmann, Saundra S. Duncan, editor(s)
1979, Techniques of Water-Resources Investigations 05-A1
Chapter Al of the manual contains methods used by the U.S. Geological Survey to collect, preserve, and analyze water samples for their content of dissolved minerals and gases. Among the topics discussed are selection of sampling sites, frequency of sampling, sampling equipment, sample preservation, laboratory equipment and instrumental techniques, accuracy...
A synoptic approach for analyzing erosion as a guide to land-use planning
William M. Brown III, Walter G. Hines, David A. Rickert, Gary L. Beach
1979, Circular 715-L
A synoptic approach has been devised to delineate the relationships that exist' between physiographic factors, land-use activities, and resultant erosional problems. The approach involves the development of an erosional-depositional province map and a numerical impact matrix for rating the potential for erosional problems. The province map is prepared by collating...
Storm and flood of July 31-August 1, 1976, in the Big Thompson River and Cache la Poudre River basins, Larimer and Weld Counties, Colorado
Jerald F. McCain, R. R. Shroba
1979, Professional Paper 1115-A,B
PART A: Devastating flash floods swept through the canyon section of Larimer County in north-central Colorado during the night of July 31-August I, 1976, causing 139 deaths, 5 missing persons, and more than $35 million in total damages. The brunt of the storms occurred over the Big Thompson River...
The Alaskan Mineral Resource Assessment Program: Guide to information contained in the folio of geologic and mineral resource maps of the Chandalar quadrangle, Alaska
H. N. Reiser, W. P. Brosge, J. H. DeYoung, S.P. Marsh, T. D. Hamilton, J. W. Cady, N. R. D. Albert
1979, Circular 758
The Chandalar quadrangle in east-central Alaska was investigated by a multidisciplinary research group to assess the mineral resource potential of the quadrangle. This circular serves as a guide to and integrates with a folio of 10 miscellaneous field study (MF) maps and 2 open-file (OF) reports (table 1) concerned with...
The magnetic charts of the United States for Epoch 1975
Eugene B. Fabiano, W. J. Jones, Norman W. Peddie
1979, Circular 810
Approximately 24,000 measurements taken from 1900 to 1974 were analyzed by least-squares methods to produce a series of five magnetic charts of the United States for 1975. A feature of the analysis, differing from techniques used for previous editions of the national chart, is that analytic models define the regional...
