The U.S. geological survey rass-statpac system for management and statistical reduction of geochemical data
G. VanTrump Jr., A.T. Miesch
1977, Computers & Geosciences (3) 475-488
RASS is an acronym for Rock Analysis Storage System and STATPAC, for Statistical Package. The RASS and STATPAC computer programs are integrated into the RASS-STATPAC system for the management and statistical reduction of geochemical data. The system, in its present form, has been in use for more than 9 yr...

Interpretation of discordant 40Ar/39Ar age-spectra of mesozoic tholeiites from Antarctica
R.J. Fleck, J. F. Sutter, D.H. Elliot
1977, Geochimica et Cosmochimica Acta (41) 15-32
Conventional K-Ar ages of tholeiitic basalts of the Ferrar Group in the central Transantarctic Mountains indicate significant loss of radiogenic 40Ar from this unit over much of its outcrop area. Argon loss varies inversely with amount of devitrified matrix in the basalts, which have not been thermally or tectonically disturbed since...
Earthquake prediction: A perspective for a national program

Earthquakes, December 1976
W. J. Person
1977, Earthquake Information Bulletin (USGS) (9) 28-29
The month of December was seismically quiet compared to the previous months of the year. There were no major earthquakes during the month and only one that caused fatalities. On December 8, the Republic of South Africa was struck by an earthquake that caused deaths and damage. The United States...
Measuring the size of an earthquake
W. Spence
1977, Earthquake Information Bulletin (USGS) (9) 21-23
Earthquakes occur in a broad range of sizes. A rock burst in an Idaho silver mine may involve the fracture of 1 meter of rock; the 1965 Rat island earthquake in the Aleutian arc involved a 650-kilometer lenght of Earth's crust. Earthquakes can be even smaller and even larger. if...
Evaluating the intensity of U.S. earthquakes
R. Simon, C. Stover
1977, Earthquake Information Bulletin (USGS) (9) 24-29
The intensity scale based on the Modified Mercalli Scale of 1931 (MM scale) measures the effects of seismic shaking. Intensity estimations are often the only representation of the size of an earthquake when small shocks occur in areas far removed from seismograph stations that can record them instrumentally. The impossibility...
Earthquakes: August-September 1976
W. J. Person
1977, Earthquake Information Bulletin (USGS) (9) 32-33
Destructive earthquakes continued to strike in many parts of the world during this period. The sparsely populated area of the New Hebrides Islands in the southwest Pacific was struck by a major earthquake (one with a magnitude between 7.0 and 7.9). A great earthquake (magnitude 8.0 or above) struck just...

When an earthquake occurs, we must be ready at the National Earthquake Information Service (NEIS) in Golden, Colo., to provide information as to its magnitude and epicenter as quickly as possible.This information is given to agencies concerned with disaster relief and to the press. A typical scenario for our operations...
Microearthquake--array studies of the seismicity in Southeast Missouri
W. Stauder
1977, Earthquake Information Bulletin (USGS) (9) 8-13
In 1811-12, a series of disastrous earthquakes struck the southeast Missouri region (see "The Mississippi Valley earthquakes of 1811 and 1812" by Otto W. Nuttli in the Earthquake Information Bulletin, March-April 1974). Earthquake activity continues in the area at present, showing that the seismic hazard is still there. We know little about the...

The display flight of The North American Ruddy Duck
M. R. Miller, R.M. McLandress, B.J. Gray
1977, The Auk (94) 140-142
Sexual behavior of the North American Ruddy Duck (Oxyura jamaicensis), as summarized by Johnsgard (1965: 323-327), includes a display variously referred to as the ringing rush (Johnsgard 1965: 325; 1967), ring rush (Johnsgard 1966), and/or display flight (Johnsgard 1966, 1967), which males perform as a short rush across the water...

Energy allocation patterns of a sprouting and nonsprouting species of Arctostaphylos in the California chaparral
Jon E. Keeley, Sterling C. Keeley
1977, American Midland Naturalist (98) 1-10
The r- and K-selection theory was used to generate testable hypotheses about patterns of energy allocation in two chaparral shrubs of different reproductive strategies. Terminal-branchlet vegetative and reproductive biomass of the nonsprouting Arctostaphylos glauca and the sprouting A. glandulosa were sampled in a 23-year-old and a 90-year-old stand of chaparral...
