Clarifications and corrections of the dates of issue of some publications containing descriptions of North American birds
M. Ralph Browning, Burt L. Monroe Jr.
1991, Archives of Natural History (18) 381-405
The date of issue of a work containing a new scientific name determines the date the name is available and, therefore, the priority of the name with respect to other applied to the same taxon. Differences between the dates printed in publications and the actual dates of issues often...

G. L. Patterson
1990, Water-Resources Investigations Report 89–4129
During 1984, above-normal ground-water levels flooded the fields and basements in the vicinity of the Crex Meadows Wildlife Area. In response to concerns of neighboring farmers and homeowners, the Wisconsin Department of Natural Resources and the U.S. Geological Survey began a cooperative study to assess ground-water conditions in the area...
Hydrologic effects of well-field operations in a wetland, Dade County, Florida
R.S. Sonenshein, Ronald H. Hofstetter
1990, Water-Resources Investigations Report 90-4143
Water-level, canal stage and discharge, and rainfall data collected in a wetland in Dade County, Florida, were analyzed to determine the effects of pumping at the Northwest Well Field on water levels in the wetland. The Northwest Well Field is the first major well field in south Florida to be...
Water-resources potential of the freshwater lens at Key West, Florida
D.J. McKenzie
1990, Water-Resources Investigations Report 90-4115
The island of Key West lies at the end of the Florida Keys, about 150 miles southwest of Miami. The public-water supply for the island is provided by the Florida Keys Aqueduct Authority Well Field near Miami. However, there are many privately owned wells on the island that tap the...
A method to estimate canal leakage to the Biscayne Aquifer, Dade County, Florida
D.A. Chin
1990, Water-Resources Investigations Report 90-4135
The leakage characteristics of channels that partially penetrate the Biscayne aquifer and have reduced bed permeability were studied. Leakage characteristics were described in terms of a reach transmissivity-defined as the volume flow rate out of the channel per unit length of the channel per unit drawdown, where drawdown is defined...

Economic implications of petroleum field size distributions
Emil D. Attanasi, Lawrence J. Drew
1990, Energy Exploration & Exploitation (8) 245-257
The unprecedented natural gas price increases in the late 1970's and early 1980's allowed a glimpse of part of the in-situ distribution of natural gas fields that had been hidden by economic truncation. Analysis of those discoveries shows the distribution to be characterized by progressively larger numbers of fields as...

Underwater research methods for study of nuclear bomb craters, Enewetak, Marshall Islands
E.A. Shinn, R.B. Halley, J. L. Kindinger, J.H. Hudson, R.A. Slate
1990, Conference Paper
Three craters, created by the explosion of nuclear fusion devices, were mapped, sampled, core drilled and excavated with airlifts at Enewetak Atoll in the Marshall Islands by using scuba and a research submersible. The craters studied were Mike, Oak, and Koa. Tests took place near sea level at the transition...
Pesticide and PCB residues for loggerhead shrikes in the Shenandoah Valley
A. K. Blumton, J.D. Fraser, R.W. Young, S. Goodbred, S.L. Porter, D.L. Luukkonen
1990, Bulletin of Environmental Contamination and Toxicology (45) 697-702
The decline in loggerhead shrike (Lanius ludovicianus) populations is widespread and coincides with the use of organochlorines that began in the late 1940's and increased until the 1970's (Morrison 1981; Robbins et al. 1986; Tate 1986). An inhabitant of farmland areas, loggerhead shrikes prey on invertebrates and small vertebrates (Bent...
Solving groundwater flow problems by conjugate-gradient methods and the strongly implicit procedure
Mary C. Hill
1990, Water Resources Research (26) 1961-1969
The performance of the preconditioned conjugate-gradient method with three preconditioners is compared with the strongly implicit procedure (SIP) using a scalar computer. The preconditioners considered are the incomplete Cholesky (ICCG) and the modified incomplete Cholesky (MICCG), which require the same computer storage as SIP as programmed for a problem with...
Toxicity of inorganic and organic selenium to Daphnia magna (cladocera) and Chironomus riparius (diptera)
Christopher G. Ingersoll, F.J. Dwyer, T.W. May
1990, Environmental Toxicology and Chemistry (9) 1171-1181
Elevated concentrations of selenium (Se) have been previously measured in biota sampled from the Kesterson National Wildlife Refuge (KNWR) in the San Joaquin Valley of central California. We conducted acute and chronic toxicity tests with the cladoceran Daphnia magna and the midge Chironomus riparius to determine the toxicity or bioaccumulation...
Toxicity of organic selenium in the diet to chinook salmon
Steven J. Hamilton, Kevin J. Buhl, Neil L. Faerber, Fern A. Bullard, Raymond H. Wiedmeyer
1990, Environmental Toxicology and Chemistry (9) 347-358
The toxicity of two organoselenium diets was evaluated in 90- to 120-d partial life cycle tests with two life stages of chinook salmon (Oncorhynchus tshawytscha Walbaum). One of the diets contained fish meal made from high-selenium mosquitofish (Gambusia affinis Baird and Girard) collected from the selenium-laden San Luis Drain, California...

Ground-water hydrology of Pahvant Valley and adjacent areas, Utah
1990, Technical Publication 98
The primary ground-water reservoir in Pahvant Valley and adjacent areas is in the unconsolidated basin fill and interbedded basalt. Recharge in 1959 was estimated to be about 70,000 acre-feet per year and was mostly by seepage from streams, canals, and unconsumed irrigation water and by infiltration of precipitation. Discharge in...

Ground-water resources and simulated effects of withdrawals in the East Shore area of Great Salt Lake, Utah
David W. Clark, Cynthia L. Appel, Patrick M. Lambert, Robert L. Puryear
1990, Technical Publication 93
The ground-water resources in the East Shore area of Great Salt Lake, Utah, were studied to better define the ground-water system; to document changes in ground-water levels, quality, and storage; and to simulate effects of an increase in ground-water withdrawals. The East Shore aquifer system is in basin-fill deposits, and...
Base of moderately saline ground water in San Juan County, Utah
Lewis Howells
1990, Technical Publication 94
The base of moderately saline ground water (water that contains from 3,000 to 10,000 milligrams per liter of dissolved solids) was delineated for San Juan County, Utah, based on water-quality data and on formation-water resistivities determined from geophysical well logs using the resistivity-porosity, spontaneous-potential, and resistivity-ratio methods. These data and...
