Hydrology of the North Cascades region, Washington: 2. A proposed hydrometeorological streamflow prediction method
Wendell V. Tangborn, Lowell A. Rasmussen
1976, Water Resources Research (12) 203-216
On the basis of a linear relationship between winter (October-April) precipitation and annual runoff from a drainage basin (Rasmussen and Tangborn, 1976) a physically reasonable model for predicting summer (May-September) streamflow from drainages in the North Cascades region was developed. This hydrometeorological prediction method relates streamflow for a season beginning...

1976, Report
The U.S. Soil Conservation Service is actively engaged in the implementation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...

Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, August 1974 and chemical monitoring from July 1972 to June 1974
Wilbur C. Ballance, William Thordarson
1976, Report
Radiochemical data from the Arnchitka Island study area were obtained from water samples collected by the U.S. Geological Survey during August 1974. Tritium determinations were made on 18 samples, and gross alpha and gross beta/ gamma determinations were made on 12 samples. No appreciable differences were found between the data...
How did the 1906 San Francisco earthquake occur?
W. Thatcher
1976, Earthquake Information Bulletin (USGS) (8) 8-13
The 1906 earthquake in San Francisco was of magnitude 8.3 and was the most destructive in the history of the United States. Because this part of California is now much more heavily populated, intense studies have been made of the 1906 earthquake in an effort to understand how it occurred...
Radiochemical monitoring of water after the Cannikin event, Amchitka Island, Alaska, May 1974
William Thordarson, Wilbur C. Ballance
1976, Report
During May 1974, the U.S. Geological Survey collected water samples from Amchitka Island, Alaska. Tritium determinations were made on 99 water samples, and dissolved gross alpha and gross beta/gamma determinations were made on 34 water samples, No appreciable differences were found between the data obtained in May 1974 and the...
Interactive computer programs for petrologic modeling with extended Q-mode factor analysis
A.T. Miesch
1976, Computers & Geosciences (2) 439-492
An extended form of Q-mode factor analysis may be used if the row-sums of the data matrix are constant and can be helpful especially in developing and testing petrologic-mixing models for igneous systems. The first step is to represent the sample compositions as unit vectors in M-dimensional space and then...
Concretionary manganese-iron oxides in streams and their usefulness as a sample medium for geochemical prospecting
G.A. Nowlan
1976, Journal of Geochemical Exploration (6) 193-210
Correlation studies of 400 samples of sieved stream sediments and 325 samples of fluvial, concretionary Mn-Fe oxides from Maine resulted in the separation of elements into the following categories: (1) elements not scavenged by Mn-Fe oxides — B, Cr, K, Mg, Rb, Sc, Ti, V, and Zr; (2) elements...
Turbidity distribution in the Atlantic Ocean
Stephen Eittreim, E. M. Thorndike, L. Sullivan
1976, Deep-Sea Research and Oceanographic Abstracts (23) 1115-1127
The regional coverage of Lamont nephelometer data in the North and South Atlantic can be used to map seawater turbidity at all depths. At the level of the clearest water, in the mid-depth regions, the turbidity distribution primarily reflects the pattern of productivity in the surface waters. This suggests that...
Observations of eruption clouds from Sakura-zima volcano, Kyushu, Japan from Skylab 4
J. D. Friedman, G. Heiken, D. Randerson, D.S. McKay
1976, Journal of Volcanology and Geothermal Research (1) 305-329
Hasselblad and Nikon stereographic photographs taken from Skylab between 9 June 1973 and 1 February 1974 give synoptic plan views of several entire eruption clouds emanating from Sakura-zima volcano in Kagoshima Bay, Kyushu, Japan. Analytical plots of these stereographic pairs, studied in combination with meteorological data, indicate that the eruption...
Extended cabfac and Qmodel computer programs for Q-mode factor analysis of compositional data
J.E. Klovan, A.T. Miesch
1976, Computers & Geosciences (1) 161-178
The computer program CABFAC for Q-mode factor analysis of geologic data has been extended for use with data having constant row-sums. Another program, QMODEL, reads an output file from CABFAC and can be used to develop a variety of Q-mode models. The models serve to reproduce estimates of the original...
Progress in remote sensing (1972-1976)
W. A. Fischer, W. R. Hemphill, Allan Kover
1976, Photogrammetria (32) 33-72
This report concerns the progress in remote sensing during the period 1972–1976. Remote sensing has been variously defined but is basically the art or science of telling something about an object without touching it. During the past four years, the major research thrusts have been in three areas: (1) computer-assisted enhancement and...
Instrumental activation analysis of coal and fly ash with thermal and epithermal neutrons and short-lived nuclides
E. Steinnes, J.J. Rowe
1976, Analytica Chimica Acta (87) 451-462
Instrumental neutron activation analysis is applied to the determination of about 25 elements in coals and fly ash by means of nuclides with half-lives of less than 48 h ; thermal and epithermal irradiations are used. The results indicate that epithermal activation is preferable for twelve of the elements (Ga,...

G. A. Desborough, Janet K. Pitman, C. Huffman Jr.
1976, Chemical Geology (17) 13-26
Ten samples from drillcore of two rich oil-shale beds from the Parachute Creek Member of the Eocene Green River Formation, Piceance Creek basin, Colorado, and Uinta Basin, Utah, were analyzed for 37 major, minor, and trace elements. For 23 of these elements, principal mineralogical residence is established or suggested and...
The dissolution of calcite in CO2-saturated solutions at 25°C and 1 atmosphere total pressure
Niel Plummer, T.M.L. Wigley
1976, Geochimica et Cosmochimica Acta (40) 191-202
The dissolution of Iceland spar in CO2-saturated solutions at 25°C and 1 atm total pressure has been followed by measurement of pH as a function of time. Surface concentrations of reactant and product species have been calculated from bulk fluid data using mass transport theory and a model that accounts...
Q-mode factor analysis of compositional data
A.T. Miesch
1976, Computers & Geosciences (1) 147-159
An extended form of the method of Q-mode factor analysis may be used if the rows of the data matrix sum to a constant. The constant row-sum provides a means for scaling the factor model to conform to the units of the original data in such forms as proportions, percentages,...
The national coal-resources data system of the U.S. geological survey
M.D. Carter
1976, Computers & Geosciences (2) 331-340
The National Coal Resources Data System (NCRDS) was designed by the U.S. Geological Survey (USGS) to meet the increasing demands for rapid retrieval of information on coal location, quantity, quality, and accessibility. An interactive conversational query system devised by the USGS retrieves information from the data bank through a standard...
