The United States Geological Survey in Alaska: Accomplishments during 1977
Kathleen M. Johnson, editor(s)
1978, Circular 772-B
United States Geological Survey projects in Alaska study a wide range of topics of economic and scientific interest. Work done in 1977 includes contributions to economic geology, regional geology, stratigraphy, engineering geology, hydrology, and marine geology. Many maps and reports covering various aspects of the geology and mineral and water...
Rock pushing and sampling under rocks on Mars
H. J. Moore, S. Liebes Jr., D.S. Crouch, L.V. Clark
1978, Professional Paper 1081
Viking Lander 2 acquired samples on Mars from beneath two rocks, where living organisms and organic molecules would be protected from ultraviolet radiation. Selection of rocks to be moved was based on scientific and engineering considerations, including rock size, rock shape, burial depth, and location in a sample field. Rock...
Description of CRIB, the GIPSY retrieval mechanism, and the interface to the General Electric MARK III Service : CRIB, the mineral resources data bank of the U.S. Geological Survey--guide for public users, 1977
James Alfred Calkins, Eleanor K. Keefer, Regina A. Ofsharick, George T. Mason, Patricia Tracy, Mary Atkins
1978, Circular 755-A
The U.S. Geological Survey's Computerized Resources Information Bank (CRIB) is being made available for public use through the computer facilities of the University of Oklahoma and the General Electric Company, U.S.A. The use of General Electric's worldwide information-services network provides access to the CRIB file to a worldwide clientele. This...
Description of individual data items and codes in CRIB
Eleanor K. Keefer, James Alfred Calkins
1978, Circular 755-B

The use of General Electric's worldwide information-services network provides access to the CRIB file to a worldwide clientele. This...
Collection, storage, retrieval, and publication of water-resources data
C. R. Showen (compiler)
1978, Circular 756
This publication represents a series of papers devoted to the subject of collection, storage, retrieval, and publication of hydrologic data. The papers were presented by members of the U.S. Geological Survey at the International Seminar on Organization and Operation of Hydrologic Services, Ottawa, Canada, July 15-16, 1976, sponsored by the...
The Energy Lands Program of the U.S. Geological Survey, fiscal year 1976
John O. Maberry (compiler)
1978, Circular 778
The Energy Lands Program of the U.S. Geological Survey comprises several projects that conduct basic and interpretive earth-science investigations into the environmental aspects of energy-resource recovery, transmission, and conversion. More than half the coal reserves of the United States occur west of the Mississippi River; therefore, the program concentrates mostly...
Estimation of ground motion parameters
David M. Boore, W. B. Joyner, A.A. Oliver, R.A. Page
1978, Circular 795
Strong motion data from western North America for earthquakes of magnitude greater than 5 are examined to provide the basis for estimating peak acceleration, velocity, displacement, and duration as a function of distance for three magnitude classes. A subset of the data (from the San Fernando earthquake) is used to...
Water-quality indices for specific water uses
J.D. Stoner
1978, Circular 770
Water-quality indices were developed to assess waters for two specific uses--public water supply and irrigation. The assessment for a spcific water use is based on the availability f (of (1) a set of limits for each water quality property selected, (2) a rationale for selection, and (3) information that permits...
Computer model of two-dimensional solute transport and dispersion in ground water
Leonard F. Konikow, J.D. Bredehoeft
1978, Techniques of Water-Resources Investigations 07-C2
This report presents a model that simulates solute transport in flowing ground water. The model is both general and flexible in that it can be applied to a wide range of problem types. It is applicable to one- or two-dimensional problems involving steady-state or transient flow. The model computes changes...
A theoretical basis for exploration for native copper in northern Wisconsin
Walter S. White
1978, Circular 769
Exploration for native copper in the Keweenawan lavas of northern Wisconsin has been concentrated in areas of relatively shallow overburden that have sparse to numerous outcrops. Lack of success of this exploration suggests that if large deposits, comparable to those of northern Michigan, are present, they are more likely to...
Program for evaluating stream quality in North Carolina
Hugh B. Wilder, Clyde E. Simmons
1978, Circular 764
The design and objectives of the program for evaluating stream quality in North Carolina are described. Using water-quality and streamflow data collected since the 1940's, a study is underway to define certain variations in water quality, to quantify the effects of man 's activities on water quality, and to determine...
A guide to obtaining information from the USGS 1978
Paul F. Clarke (compiler), Helen E. Hodgson, Gary W. North
1978, Circular 777
For almost 100 years, the USGS (U.S. Geological Survey) has served Federal, State, and local governments and the public by collecting, analyzing, and publishing detailed information about the Nation 's mineral, land, and water resources. This information is released in a variety of map, book, and other formats and is...
Stratigraphic test well, Nantucket Island, Massachusetts
David W. Folger, J.C. Hathaway, R. A. Christopher, P. C. Valentine, C. W. Poag
1978, Circular 773
The U.S. Geological Survey, in cooperation with the Massachusetts Water Resources Commission and the Nantucket Conservation Foundation, continuously cored 514 m of sediment and volcanic rock in a stratigraphic and water-quality test near the geographic center of Nantucket Island. Stratified sediments were divided texturally into three zones: the upper zone...
