Exact Scheffé-type confidence intervals for output from groundwater flow models: 1. Use of hydrogeologic information
Richard L. Cooley
1993, Water Resources Research (29) 17-33
A new method is developed to efficiently compute exact Scheffé-type confidence intervals for output (or other function of parameters) g(β) derived from a groundwater flow model. The method is general in that parameter uncertainty can be specified by any statistical distribution having a log probability density function (log pdf) that can...
Status of Pacific Black Brant Branta bernicla nigricans on Wrangel Island, Russian Federation
David H. Ward, Dirk V. Derksen, Sergei Kharitonov, Mikhail Stishov, Vasily V. Baranyuk
1993, Wildfowl (44) 39-48
Abundance, distribution, and habitat selection of breeding and moulting Pacific Black Brant were studied on Wrangel Island in 1989-91. Two nests and <10 family flocks of Brant were found during ground searches in previously known nesting areas. The breeding population has declined from 1000-2000 pairs to probably <100 pairs. An...
Family stability in greater white-fronted geese
Craig R. Ely
1993, The Auk (110) 425-235
I investigated the stability of parent-offspring bonds, and sibling-sibling bonds of neck-banded Greater White-fronted Geese (Anser albifrons frontalis) during winters (September-May) in California and southern Oregon from 1979 to 1989. Geese captured at feeding sites were more likely to be in social groups than those captured at roosting sites. Offspring...
Crude oil in a shallow sand and gravel aquifer—I. Hydrogeology and inorganic geochemistry
P.C. Bennett, D.E. Siegel, M.J. Baedecker, M. F. Hult
1993, Applied Geochemistry (8) 529-549
Changes in the distribution of inorganic solutes in a shallow ground water contaminated by crude oil document a series of geochemical reactions initiated by biodegradation of the oil. Upgradient of an oil body floating on the water table, oxidation of oil to carbonic acid dissolves carbonate minerals in the aquifer...
Water resources data, Connecticut, water year 1992
M.A. Cervione Jr., B.S. Davies III, J.R. Bohr, B.W. Hunter
1993, Water Data Report CT-92-1
Water resources data for the 1992 water year for Connecticut consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels of ground-water wells. Specifically, it contains: (1) discharge records for 44 streamflow-gaging stations, and for 1 tidal...

Brown coal maceral distributions in a modern domed tropical Indonesian peat and a comparison with maceral distributions in Middle Pennsylvanian–age Appalachian bituminous coal beds
William C. Grady, Cortland F. Eble, Sandra G. Neuzil
1993, Special Paper of the Geological Society of America (286) 63-82
Analyses of modern Indonesian peat samples reveal that the optical characteristics of peat constituents are consistent with the characteristics of macerals observed in brown coal and, as found by previous workers, brown-coal maceral terminology can be used in the analysis of modern peat. A core from the margin and...

Cleat development in coals of the Upper Cretaceous Mesaverde Formation, Pilot Butte area, Wind River Reservation, Wyoming
R. C. Johnson, A.C. Clark, R.J. Szmajter
1993, Conference Paper, Oil and gas and other resources of the Wind River Basin, Wyoming; Special symposium
The cleat system developed in low-rank (mean viltrinite reflectance of 0.43 to 0.5 percent) coal beds in the Upper Cretaceous Mesaverde Formation was studied in outcrop and in coreholes drilled for coalbed methane evaluation near Pilot Butte in the central part of the Wind River Reservation. Cleats are the...

1:100,000-scale Counties of the United States
U.S. Dept of Commerce Bureau of Census
1993, Report
This is a coverage of the county boundaries of the conterminous United States (AK, HI and Puerto Rico are available separately). The lines were extracted from U.S. Census TIGER/line files using an AML program (see 4.), written by Doug Nebert and Mark Negri, running on two Data General 6220 servers....
Response of a 42-storey steel-frame building to the Ms = 7.1 Loma Prieta earthquake
E. Safak
1993, Engineering Structures (15) 403-421
A set of 14 acceleration records was obtained from a 42-storey steel-frame building, the Chevron Building, in San Francisco during the Ms= 7.1">Ms= 7.1 Loma Prieta earthquake of 17 October 1989. Data were analysed using a system identification method based on the discretetime linear filtering, and...
Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in the Pine River Project area, Southern Ute Indian Reservation, southwestern Colorado and northwestern New Mexico, 1988-89
D. L. Butler, R. P. Krueger, B. C. Osmundson, A. L. Thompson, J. J. Formea, D. W. Wickman
1993, Water-Resources Investigations Report 92-4188
During 1988-89, water, bottom sediment, biota, soil, and plants were sampled for a reconnaissance investigation of the Pine River Project area in southwestern Colorado. Irrigation drainage does not seem to be a major source of dissolved solids in streams. Concentrations of manganese, mercury, and selenium exceeded drinking-water regulations in some...

Corrosiveness of ground water in the Kirkwood-Cohansey aquifer system of the New Jersey Coastal Plain
J. L. Barringer, G. R. Kish, A. J. Velnich
1993, Water-Resources Investigations Report 90-4180
Ground water from the unconfined part of the Kirkwood-Cohansey aquifer system in the New Jersey Coastal Plain typically is corrosive-- that is, it is acidic, soft, and has low concentrations of alkalinity. Corrosive ground water has the potential to leach trace elements and asbestos fibers from plumbing materials used...

A model of the productivity of the northern pintail
J.D. Carlson Jr., W.R. Clark, Erwin E. Klaas
1993, Biological Report 7
We adapted a stochastic computer model to simulate productivity of the northern pintail (Anas acuta). Researchers at the Northern Prairie Wildlife Research Center of the U.S. Fish and Wildlife Service originally developed the model to simulate productivity of the mallard (A. platyrhynchos). We obtained data and descriptive information on the...
Patterns of orographic uplift in the Sierra Nevada and their relationship to upper-level atmospheric circulation
Edward Aguado, Daniel R. Cayan, Brian D. Reece, Larry Riddle
1993, Conference Paper, Proceedings of the ninth annual pacific climate (PACLIM) workshop
We examine monthly and seasonal patterns of precipitation across various elevations of the eastern Central Valley of California and the Sierra Nevada. A measure of the strength of the orographic effect called the “precipitation ratio” is calculated, and we separate months into four groups based on being wet or dry...
Restoration ecology: longterm evaluation as an essential feature of rehabilitation
John E. Gannon
1993, Buffalo Environmental Law Journal (1) 267-277
In its brief existence as a recognized scientific discipline, restoration ecology has focused almost exclusively on terrestrial and wetland habitat. As a consequence, aquatic restoration and rehabilitation, an important component of restoration ecology is a relatively new discipline. This article examines the ecosystem approach to rehabilitation of the...
