Distribution functions for statistics derived from bivariate normal and bivariate two-parameter log-normal populations
James Richard Slack, Nicholas C. Matalas, James R. Wallis
1976, Open-File Report 76-214
The distribution functions for hydrologic statistics that may be used to assess the significance of differences between sample means, standard deviations, coefficients of skewness, and coefficients of variations are obtained by Monte Carlo experiments. The distributions are expressed as functions of sample size, cross correlation, and skewness. In general, the...

Preliminary investigations on computational methods for solving the two-point seismic ray-tracing problem in a heterogeneous and isotropic medium
J.P. Yang, William Hung Kan Lee
1976, Open-File Report 76-707
Two-point seismic ray tracing is an important problem in seismology. In this report, we study this problem by first deriving the differential equations governing seismic wave propagation between two end points in a 3-dimensional heterogeneous and isotropic medium. We then formulate three numerical schemes to solve the two-point ray-tracing problem....
A reconnaissance of the effects of a forest fire on water quality in Kings Canyon National Park, California
Ray J. Hoffman, Rodger F. Ferreira
1976, Open-File Report 76-497
Following two forest fires in the Roaring River drainage basin, Kings Canyon National Park, Calif., water samples were collected from May to July 1974 to determine water-quality changes resulting from the fires. Field measurements included alkalinity , pH, specific conductance, temperature, and discharge. Samples were analyzed in the laboratory for...
Volcanic rocks of the McDermitt Caldera, Nevada-Oregon
Robert C. Greene
1976, Open-File Report 76-753
The McDermitt caldera, a major Miocene eruptive center is locatedin the northernmost Great Basin directly west of McDermitt, Nev. The alkali rhyolite of Jordan Meadow was erupted from the caldera and covered an area of about 60,000 sq km; the volume of rhyolite is about 960 cubic km. Paleozoic and...

Limnological investigation of six lakes in southeast Alaska
George A. McCoy, William W. Wiggins, Artwin E. Schmidt
1976, Water-Resources Investigations Report 76-122
Limnological data were collected from six lakes in southeast Alaska in 1974. The data include concentrations of major inorganic constituents, nutrients, selected trace metals, total organic carbon, and chlorophyll. Vertical profiles of specific conductance, temperature, dissolved-oxygen saturation, and pH were drawn. With the exception of Redoubt Lake, all of the...
Computer simulation model of the Pleistocene valley-fill aquifer in southwestern Essex and southeastern Morris counties, New Jersey
Harold Meisler
1976, Water-Resources Investigations Report 76-25
A finite-difference digital computer model was developed to simulate a buried valley-fill aquifer consisting of outwash sand and gravel deposited in a series of valleys cut into bedrock of Triassic age. Till, clay, silt, and muck function as an overlying semiconfining layer. The bedrock which is represented as an unconfined...
Water resources of south-central Missouri
E. E. Gann, Edward Joseph Harvey, Don E. Miller
1976, Hydrologic Atlas 550
This atlas describes hydrology in an area of approximately 23 ,000 sq mi and includes all or parts of 38 counties in Missouri. The area is bounded on the north by the southern edge of the Missouri River flood plain, on the east by the Mississippi River and the Plateaus-Lowlands...
Chemical characteristics of the major thermal springs of Montana
Robert H. Mariner, T. S. Presser, William C. Evans
1976, Open-File Report 76-480
Twenty-one thermal springs in western Montana were sampled for chemical, isotope, and gas compositions. Most of the springs issue dilute to slightly saline sodium-bicarbonate waters of neutral to slightly alkaline pH. A few of the springs issue sodium-mixed anion waters of near neutral pH. Fluoride concentrations are high in most...
Preliminary summary of the 1976 Atlantic Margin Coring Project of the U.S. Geological Survey

1976, Open-File Report 76-844
The U.S. Geological Survey Atlantic Margin Coring Project, 1976, a 60-day expedition to obtain core samples by drilling beneath the floor of the Continental Shelf and Slope of the eastern United States, was carried out in July, August, and September 1976 aboard D/V GLOMAR CONCEPTION. The coring penetrated as much...

Water resources of northwestern Wyoming
Edward Riley Cox
1976, Hydrologic Atlas 558
This 3-sheet map report describes the hydrologic conditions in northwestern Wyoming. The increasing number of tourists and residents and the shifting of overnight accommodations for tourists from Yellowstone and Grand Teton National Parks to nearby areas may result in the need for development of additional water supplies in northwestern Wyoming....
