Interstation correlation of peak-flow estimates
Clayton H. Hardison
1976, Journal of Research of the U.S. Geological Survey (4) 221-222
Equations are given for using the correlation coefficient between annual peaks at a pair of stream gaging stations to estimate the interstation correlation coefficient of estimated T-year peaks, computed standard deviations, and computed skew coefficients at the same pair of stations. The equations are based on statistics computed from samples...
Flameless atomic absorption determination of bismuth in soils and rocks
W. H. Ficklin, F. N. Ward
1976, Journal of Research of the U.S. Geological Survey (4) 217-220
Recent advances in flameless atomic absorption allow determinations of bismuth in concentrations as small as 50 ppb in 0.2 g of rock or soil sample. The sample is fused with sodium bisulfate and the fusion product is leached with hot 2 M hydrochloric acid and treated with ammonium citrate, (ethylenedinitrilo)...
A review of the minerals of the alunite-jarosite, beudantite, and plumbogummite groups
Theodore Botinelly
1976, Journal of Research of the U.S. Geological Survey (4) 213-216
Minerals of the alunite-jarosite, beudantlte, and plumbogummite groups can be divided on the basis of iron or aluminum content into two groups which are consistent in optical and X-ray characteristics. Both chemical and X-ray data are needed for identification....
Definitive X-ray powder data for covellite, anilite, djurleite, and chalcocite
Robert W. Potter II, Howard T. Evans Jr.
1976, Journal of Research of the U.S. Geological Survey (4) 205-212
By using the Guinier-Hägg focusing X-ray powder camera with CrKα1 and CuKα1 radiations, new powder data for covellite (CuS), anilite (Cu7S4, djurleite (Cu1.934S), and low chalcocite (Cu2S) have been obtained from synthetic and natural materials. The powder data were treated by least-squares analysis to obtain the best unit-cell parameters consistent...
The volumetric properties of H2O — A graphical portrayal
James R. Fisher
1976, Journal of Research of the U.S. Geological Survey (4) 189-193
A graphical display of the volumetric properties of H2O is presented as density (0.01 to 1.0 g-cm-3) contoured on pressure-temperature coordinates and pressure (1-10,000 bars) contoured on density-temperature coordinates over the temperature range 0-1,000 °C. Data were obtained from sources published during 1964-1969; several minor inconsistencies are observed and attributed...

Edward W. Wolfe, V. S. Reed
1976, Journal of Research of the U.S. Geological Survey (4) 171-180
The Apollo 17 spacecraft landed in a narrow valley that embays mountainous terrain near the southeastern edge of Mare Serenitatis. Two overlapping basin structures underlie Mare Serenitatis: a larger one to the south and a smaller one to the north. The massifs and sculptured hills in the Taurus-Littrow area and...

Richard F. Madole
1976, Journal of Research of the U.S. Geological Survey (4) 163-169
Radiocarbon dates and stratigraphic cores from bogs, kettle ponds, and former ice-marginal lakes on the east and west sides of the Front Range, Colo., between lat 40°00' and 40°24' N. suggest that (1) valley glaciers of Pinedale age began to recede from their terminal positions between about 14,600 and 13,000...

1976, Journal of Research of the U.S. Geological Survey (4) 151-162
At the head of Turnagain Arm near Anchorage, the major lasting geologic consequence of the Alaska earthquake of 1964 was deposition of the Placer River Silt, an intertidal deposit covering an area of more than 18 km2 and containing more than 20X106 m3 of sediment. This formation, which was derived...

George O. Bachman
1976, Journal of Research of the U.S. Geological Survey (4) 135-149
Sedimentary records of Cenozoic history in southeastern New Mexico begin with the Ogallala Formation of Miocene and Pliocene age. Later records include the Gatuna Formation of early or middle Pleistocene age, Mescalero caliche, an informal term, of middle Pleistocene age, and fluvial deposits of late Pleistocene age but there are...
Geology of central Costa Rica and its implications in the geologic history of the region
Richard D. Krushensky, Enrique V. Malavassi, Rolando M. Castillo
1976, Journal of Research of the U.S. Geological Survey (4) 127-134
The oldest rocks in Costa Rica, the Nicoya Complex, crop out in an arcuate belt along the Pacific coast and outside the mapped area. The complex is an ophiolite assemblage and indicates that a Late Cretaceous arc-trench system, probably a southerly extension of the Middle America Trench, lay along and...
Determination, storage, and preservation of low molecular weight hydrocarbon gases in aqueous solution
D. J. Schultz, J. F. Pankow, D. Y. Tai, D. W. Stephens, R. E. Rathbun
1976, Journal of Research of the U.S. Geological Survey (4) 247-251
A gas chromatograph with a flame ionization detector was used in conjunction with a stripping chamber and cold trap apparatus to measure microgram-per-litre quantities of low molecular weight hydrocarbon gases in water samples. Glass bottles with ground-glass stoppers were used to store the samples. Formalin was added to stop bacterial...
Solute transport and modeling of water quality in a small stream
S. M. Zand, V. C. Kennedy, G. W. Zellweger, R.J. Avanzino
1976, Journal of Research of the U.S. Geological Survey 233-240
An injection of chloride, sodium, and stable strontium was made at a constant rate for 3 hours into Uvas Creek, Santa Clara County, Calif., to determine the mass transport processes in a small stream. Five observation points were selected within a 610-metre reach of the stream below the injection site....
The abundance and diversity of the herpetofaunas of tropical forest litters
Norman J. Scott Jr.
1976, Biotropica (8) 41-58
Quantitative and qualitative samples of amphibian and lizard faunas were taken from forest litter in Costa Rica and compared with similar samples collected in Borneo, the Philippines, and Panama. Animal abundance is about ten times greater in Costa Rican lowland wet forest than in Borneo. Radically different routes and rates...
Differential seed predation on two species of Arctostaphylos (Ericaceae)
Jon E. Keeley, R.L. Hays
1976, Oecologia (24) 71-81
The fire-prone California chaparral contains two sympatric species of shrubs: Arctostaphylos glauca and A. glandulosa. A previous study showed that in a stand where both species had similar amounts of coverage, A. glauca had fewer seeds in the soil. We attempt to answer the questions: 1) Could ground-foraging seed predators produce the lower population of A....

Geochemistry of thermal waters in Long Valley, Mono County, California
Robert H. Mariner, Lawrence M. Willey
1976, Journal of Geophysical Research (81) 792-800
Thermal springs and wells in Long Valley, California, issue sodium bicarbonate‐chloride waters containing 1000–1420 mg/l of dissolved solids. Thermal waters of sodium bicarbonate‐chloride composition are usually associated with hot‐water reservoirs. Chloride concentrations and stable isotope data indicate that the thermal waters have had varied histories. All of the thermal springs...

Terry A. Vaughan, Thomas J. O'Shea
1976, Journal of Mammalogy (57) 19-42
Daytime roosting behavior of pallid bats (Antrozous pallidus) was studied in central Arizona. Bats were present in the area from March or April until November and roosted in cliffs in colonies generally including 20 or more individuals. Pallid bats were highly selective in their choice of roost sites...

1976, AAPG Bulletin (60) 161-183
The virtually featureless Beringian shelf south of St. Lawrence Island is underlain structurally by at least 14 basins. Encompassing a total area of more than 300,000 sq km, most of the basins are either elongate structural sags, grabens, or half (asymmetric) grabens beneath the outer shelf. The regional trend of...

Nitrogen and phosphorus uptake in the Everglades Conservation Areas, Florida, with special reference to the effects of backpumping runoff
Benjamin F. McPherson, Bradley G. Waller, H. C. Mattraw
1976, Water-Resources Investigations Report 76-29
In much of the water pumped into the northern Everglades, Florida, concentrations of inorganic nitrogen and phosphorus are relatively high. These nutrients are transported in the canals or into the peripheral marshes. Concentrations decrease sharply within 330 feet or less of the canals, whereas specific conductance remains essentially unchanged within...
