Lakes of Oregon, Volume 5: Marion County
Joseph F. Rinella
1977, Report
An inventory of lakes and reservoirs of Oregon is essential for a complete evaluation of the total surface-water supply of the State and to provide a basis for answering questions about Oregon's lakes. Much of the information on lakes and reservoirs previously collected by Federal and State agencies has never...

Crater clusters and light mantle at the Apollo 17 site: A result of secondary impact from Tycho
Baerbel K. Lucchitta
1977, Icarus (30) 80-96
The morphologies of Tycho secondary craters and their ejecta deposits were studied using full-Moon, Lunar-Orbiter, and Apollo panoramic photographs. These data were compared with similar data for the secondary craters and light mantle of the Apollo 17 landing site. The results indicate that (1) the central crater cluster and the...
Some Bayesian statistical techniques useful in estimating frequency and density
Douglas H. Johnson
1977, Special Scientific Report - Wildlife 203
This paper presents some elementary applications of Bayesian statistics to problems faced by wildlife biologists. Bayesian confidence limits for frequency of occurrence are shown to be generally superior to classical confidence limits. Population density can be estimated from frequency data if the species is sparsely distributed relative to the size...

Worldwide standardized seismograph network
J. Peterson
1977, Earthquake Information Bulletin (USGS) (9) 36-45
A global network of seismographs is as indispensable to seismologists as telescopes are to astronomers. The network is used to catalog the thousands of earthquakes that occur each year and to provide the data needed for detailed studies of earthquake mechanisms, deep Earth structure, and tectonic processes. Like astronomy, seismology...

Thomas C. Winter
1977, Water Resources Research (13) 753-767
The hydrologic settings of 150 lakes in the north central United States were investigated by principal component analysis as a first attempt to develop a general classification of the hydrologic settings of lakes. Precipitation-evaporation balance and the water quality variables have high loadings on the first principal component. Highest loadings...

Estimation of the probability of success in petroleum exploration
J.C. Davis
1977, Journal of the International Association for Mathematical Geology (9) 409-427
A probabilistic model for oil exploration can be developed by assessing the conditional relationship between perceived geologic variables and the subsequent discovery of petroleum. Such a model includes two probabilistic components, the first reflecting the association between a geologic condition (structural closure, for example) and the occurrence of oil, and...
