1983, Earthquake Information Bulletin (USGS) (15) 11-15
At the beginning of the 1970's, a series of programs in seismology were initiated by different Costa Rican institutions, and some of these programs are still in the process of development. The institutions are Insituto Costaricense de Electricidad (ICE)- The Costa Rica Institute of Electricity La Universidad Nacional Autonoma (UNA)- The National...
Chemistry and microbiology of a sewage spill in South San Francisco Bay
J. E. Cloern, R.S. Oremland
1983, Estuaries (6) 399-406
During three weeks of September 1979, the breakdown of a waste treatment plant resulted in the discharge of a large volume (1.5×107m3) of primary-treated sewage into a tributary of South San Francisco Bay, California. Chemical and microbial changes occurred within the tributary as decomposition and nitrification depleted dissolved oxygen. Associated...

Determination of chloride in geological samples by ion chromatography
Stephen A. Wilson, Carol A. Gent
1983, Analytica Chimica Acta (148) 299-303
Samples of silicate rocks are prepared by sodium carbonate fusion and then treated by ion chromatography. The method was tested for geological standards with chloride concentration between 0.003 and 3%. Observed chloride concentrations comparedd favorably with literature values. The relative standard deviation and detection limit for the method were 8%...
Process and rate of dedolomitization: Mass transfer and C14 dating in a regional carbonate aquifer
W. Back, B.B. Hanshaw, Niel Plummer, P.H. Rahn, C.T. Rightmire, M. Rubin
1983, Geological Society of America Bulletin (94) 1415-1429
Regional dedolomitization is the major process that controls the chemical character of water in the Mississippian Pahasapa Limestone (Madison equivalent) surrounding the Black Hills, South Dakota and Wyoming. The process of dedolomitization consists of dolomite dissolution and concurrent precipitation of calcite; it is...
Rb-Sr, Sm-Nd, K-Ca, O, and H isotopic study of Cretaceous-Tertiary boundary sediments, Caravaca, Spain: evidence for an oceanic impact site
D.J. DePaolo, F.T. Kyte, B.D. Marshall, J. R. O’Neil, J. Smit
1983, Earth and Planetary Science Letters (64) 356-373
Isotopic ratios and trace element abundances were measured on samples of Ir-enriched clay at the Cretaceous-Tertiary boundary, and in carbonate and marl from 5 cm below and 3 cm above the boundary. Samples were leached with acetic acid to remove carbonate, and with hydrochloric acid. Leachates and residues were measured....
Land-use planning: One geologist's viewpoint
E-An Zen
1983, Environmental Conservation (10) 97-104
Planning for the best use of land and its resources should take fully into consideration the long-term consequences of each type of use in order to stretch out most beneficially the well-being of society in the future, and to protect the integrity of the land and its...
Statistical evaluation of oil and gas prospects in the outer continental shelf of the U.S. Gulf Coast
J.C. Davis, J.W. Harbaugh
1983, Journal of the International Association for Mathematical Geology (15) 217
Areas of the U.S. Gulf Coast, both onshore and offshore, are among the petroliferous regions of the United States. In offshore Louisiana and Texas, most oil and gas is associated with structurally controlled traps on the crest or flanks of domes created by the diapiric movement of salt. These structures...
Preliminary analysis of shuttle multispectral radiometer data for Southern Egypt
L. C. Rowan, Alexander F.H. Goetz, M.J. Kingston
1983, Advances in Space Research (3) 125-132
The Shuttle Multispectral Infrared Radiometer (SMIRR) is a spectroradiometer covering the region from 0.5 to 2.5 ??m in 10 channels that acquired data from spots 100 m in diameter along the subspacecraft ground track. It was flown aboard the second flight of the space shuttle Columbia, November 12-14, 1981. Data...
Automated determination of bromide in waters by ion chromatography with an amperometric detector
G. S. Pyen, D. E. Erdmann
1983, Analytica Chimica Acta (149) 355-358
An automated ion chromatograph, including a program controller, an automatic sampler, an integrator, and an amperometric detector, was used to develop a procedure for the determination of bromide in rain water and many ground waters. Approximately 10 min is required to obtain a chromatogram. The detection limit for bromide is...
Hydrothermal alteration of graywacke and basalt by 4 m NaCl
R.J. Rosenbauer, J. L. Bischoff, A. S. Radtke
1983, Economic Geology (78) 1701-1710
Separate experiments at 350 degrees C and 500 bars at a rock/fluid ratio of 1/10. Illite, dolomite, and quartz amounting to 67 percent of the original graywacke, were converted to albite and smectite. The rock gained Na and released Ca, K, heavy metals, and CO 2 to solution. In sharp contrast, the...
Use of reflectance spectra of native plant species for interpreting airborne multispectral scanner data in the East Tintic Mountains, Utah
N.M. Milton
1983, Economic Geology (78) 761-769
Representative spectra from three plant species were used to interpret the color components on a color ratio composite image. Most of the vegetation unit coincided with an altered rock unit, but many altered areas were not within the vegetation unit....
Determination of elements in National Bureau of Standards' geological reference materials SRM 278 obsidian and SRM 688 basalt by inductively coupled argon plasma-atomic emission spectrometry
J.G. Crock, F.E. Lichte, Paul H. Briggs
1983, Geostandards Newsletter (7) 335-340
Two new geologic reference materials, issued by the National Bureau of Standards as standard reference materials, have been analyzed by a precise, accurate, and rapid method of analysis for their element content. The described procedure uses a multi‐acid, low temperature digestion in a closed teflon vessel, followed by the simultaneous...
SHALLOW HYDROTHERMAL SYSTEM AT NEWBERRY VOLCANO, OREGON: A CONCEPTUAL MODEL.
Edward A. Sammel
1983, Conference Paper, Transactions - Geothermal Resources Council
Investigations at Newberry Volcano, Oregon, have resulted in a satisfactory account of the shallow hydrothermal system, but have not indicated the nature of a possible geothermal reservoir. Hot springs in the caldera probably represent the return of circulating meteoric water, warmed at shallow depths by high conductive heat flow and...
Euler-Lagrangian computation for estuarine hydrodynamics
Ralph T. Cheng
1983, Conference Paper, Numerical Methods in Laminar and Turbulent Flow, Proceedings of the International Conference
The transport of conservative and suspended matter in fluid flows is a phenomenon of Lagrangian nature because the process is usually convection dominant. Nearly all numerical investigations of such problems use an Eulerian formulation for the convenience that the computational grids are fixed in space and because the vast majority...

The fledging of common and thick-billed murres on Middleton Island, Alaska
Scott A. Hatch
1983, Journal of Field Ornithology (54) 266-274
Three species of alcids, Common and Thick-billed murres (Uria aalge and U. lomvia) and the Razorbill (Alca torda), have post-hatching developmental patterns intermediate to precocial and semi-precocial modes (Sealy 1973). The young leave their cliff nest sites at about one quarter of adult weight and complete their growth at sea....
