Computer program for the calculation of grain size statistics by the method of moments
Michael B. Sawyer
1977, Open-File Report 77-580
A computer program is presented for a Hewlett-Packard Model 9830A desk-top calculator (1) which calculates statistics using weight or point count data from a grain-size analysis. The program uses the method of moments in contrast to the more commonly used but less inclusive graphic method of Folk and Ward (1957). The...

Harold L. Shindel, William Buller, William H. Johnston
1977, Open-File Report 77-525
Basic data on the surface water, ground water, and water quality of Cortland County, New York, are presented with a short explanatory text. Seepage investigations showed that during periods of base flow, the surface-water regime cannot be predicted on the basis of flow-duration figures alone. The investigations also indicate that...

Ground water in the Lajas Valley, Puerto Rico
Henry R. Anderson
1977, Water-Resources Investigations Report 76-68
Lajas Valley is plagued with salinity and waterlogging problems of the soils. Use of brackish (500 milligrams per liter) ground water for irrigation compounded the problem until an irrigation-drainage system was constructed in 1955. Lajas Valley is an alluvium-filled trough between volcanic and limestone highlands. The alluvium, mostly clay and...

Submarine seepage of natural gas in Norton Sound, Alaska
J.D. Cline, M.L. Holmes
1977, Science (198) 1149-1153
Unusual concentrations of dissolved two- to four-carbon alkanes were observed in the waters in Norton Sound in a localized area approximately 40 kilometers south of Nome, Alaska, in 1976. The hydrocarbons were identified in the near-bottom waters downcurrent for more than 100 kilometers from a sea-floor point source. Preliminary dynamic...
Petrology of basalt from the East Pacific Rise near 21 degrees North latitude
James G. Moore, William R. Normark, Gordon R. Hess, Charles E. Meyer
1977, Journal of Research of the U.S. Geological Survey (5) 753-759
Four dredge hauls of fresh tholeiitic basalt lava were recovered from a 3.3-kilometer-wide zone at the axis of the East Pacific Rise. Petrologic and major-element chemical studies indicate that the basalt ranges from moderately fractionated varieties to one sample enriched in iron and titanium. The four samples show no symmetrical...
Geology of the gabbroic complex along the northern border of the Josephine Peridotite, Vulcan Peak area, southwestern Oregon
R. A. Loney, Glen R. Himmelberg
1977, Journal of Research of the U.S. Geological Survey (5) 761-781
The terrane bordering the alpine-type Josephine Peridotite on the north in the Vulcan Peak area, southwestern Oregon, is composed of intrusive hornblende gabbro (Middle Jurassic) and scattered remnants of clinopyroxene-bearing ultramafic rocks and amphibolite. The amphibolite, which preliminary analyses suggest is of andesitic composition, has undergone regional metamorphism to the...
Solution of three-dimensional groundwater flow equations using the strongly implicit procedure
P.C. Trescott, S. P. Larson
1977, Journal of Hydrology (35) 49-60
A three-dimensional numerical model has been coded to use the strongly implicit procedure for solving the finite-difference approximations to the ground-water flow equation. The model allows for: (1) the representation of each aquifer and each confining bed by several layers; and (2) the use of an anisotropic hydraulic conductivity at...
Lunar surface chemistry: A new imaging technique
C.G. Andre, M.J. Bielefeld, E. Eliason, L.A. Soderblom, I. Adler, J.A. Philpotts
1977, Science (197) 986-989
Detailed chemical maps of the lunar surface have been constructed by applying a new weighted-filter imaging technique to Apollo 15 and Apollo 16 x-ray fluorescence data. The data quality improvement is amply demonstrated by (i) modes in the frequency distribution, representing highland and mare soil suites, which are not evident...
A Galerkin, finite-element analysis of steady-state flow and heat transport in the shallow hydrothermal system in the East Mesa area, Imperial Valley, California
R.E. Miller
1977, Journal of Research of the U.S. Geological Survey (5) 497-509
A steady-state simulation model was applied to the shallow hydrothermal system in the East Mesa area of Imperial Valley, Calif. The steady-state equations of flow and heat transport were solved by use of a Galerkin, finite-element method. A solution was obtained by iterating between the temperature and pressure equations, using...

Baculites reduncus, n. sp., is a moderately large ammonite that has a curved shell, a large angle of taper, and a stout ovate cross section. Conspicuous broad, arcuate ribs cross the upper two-thirds of the flank. The suture, which is fairly complex, has a distinctive lateral lobe. All the types...
Seed production, seed populations in the soil and seedling production after fire for two congeneric pairs of sprouting and nonsprouting chaparral shrubs
Jon E. Keeley
1977, Ecology (58) 820-829
A study of seed production, seed storage in the soil, and seedling production after fire was undertaken for a sprouting and a nonsprouting congenerica pair of species of Ceanothus and Arctostaphylos. All species exhibited large fluctuations in annual seed production. There was a significant correlation between fruit production and precipitation...

The Pinellas Peninsula, an area of 750 square kilometres (290 square miles) in coastal west-central Florida, is a small hydrogeologic replica of Florida. Most of the Peninsula's water supply is imported from well fields as much as 65 kilometres (40 miles) inland. Stresses on the hydrologic environment of the Peninsula...

Effects of dredged channels on trace-metal migration in an estuary
Charles W. Holmes
1977, Journal of Research of the U.S. Geological Survey (5) 243-251
Determination of trace-metal levels in the sediments of the Matagorda Bay system revealed anomalously high mercury values. The distribution of the mercury-rich sediment deposits is the result of the sedimentological regime of the bay system produced by the tidal currents in the dredged channel. According to this model, the oxygenated...
High temperature heat content and heat capacity of silicate glasses: experimental determination and a model for calculation
Charles R. Bacon
1977, American Journal of Science (277) 109-135
Knowledge of the thermodynamic properties of silicate melts is fundamental to quantitative characterization of igneous systems. This paper presents new data on one of these properties, heat content, for silicate glasses and supercooled silicate liquids and derives partial molar heat contents for the glasses. The high temperature heat contents of...
Compositional variations of young basalts in the Mid-Atlantic Ridge rift valley near lat 36°49′N
W.B. Bryan, James G. Moore
1977, GSA Bulletin (88) 556-570
Fifty acoustically positioned samples of fresh basalt were collected by the submersible Alvin from the median valley of the Mid-Atlantic Ridge during the French American Mid-Ocean Undersea Study (FAMOUS) in the summer of 1974. The samples show regular compositional variations from the center of the rift valley (central lava flows) out to...
