Pacific Coast Caspian Terns: Dynamics of an expanding population
Robert E. Gill Jr., L. Richard Mewaldt
1983, The Auk (100) 369-381
Nesting distribution, age-related seasonal movements, survivorship, and mechanisms of population expansion in Pacific Coast Caspian Terns (Sterna caspia) were examined primarily through analysis of 412 recoveries of birds banded as juveniles between 1935 and 1980. Since the beginning of this century, the population has shifted from nesting in numerous small...

Aspergillosis in a red-crowned crane
R. K. Stroud, R. M. Duncan
1983, Journal of the American Veterinary Medical Association (183) 1297-1298
An unusual form of pulmonary aspergillosis in a red-crowned crane (Grus japonensis) is described in this report. The major lesion is unique because it closely resembles a lesion referred to as an aspergilloma. An aspergilloma is a single large granulomatous lesion that resembles a tumor and is caused by fungi...
Inclusion body disease of cranes: A serological follow-up to the 1978 die-off
D. E. Docherty, Renee I. Romaine
1983, Avian Diseases (27) 830-835
A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality...

R. M. Windingstad, R. M. Duncan, D. Thornburg
1983, Journal of Wildlife Diseases (19) 95-97
Avian cholera is reported for the first time in Canada geese, Branta canadensis, of the Mississippi Valley population. The disease was detected in weekly surveillance transects and was responsible to the loss of about 850 geese during the winter of 1978–1979 at localized areas in southern Illinois. Necropsies performed on 480...
Waterbird mortality from botulism type E in Lake Michigan: An update
Christopher J. Brand, Ruth M. Duncan, Scott P. Garrow, Dan Olson, Leonard E. Schumann
1983, The Wilson Bulletin (95) 269-275
Three outbreaks of botulism type E occurring in waterbirds on Lake Michigan since autumn 1976 are discussed. Natural ingestion of food containing type E toxin by Ring-billed Gulls (Larus delawarensis) and the presence of type E toxin in blood from moribund gulls were demonstrated. Concurrent presence of type C and...
Foraging dives by post-breeding northern pintails
Michael R. Miller
1983, The Wilson Bulletin (95) 294-296
Dabbling ducks (Anatini), including Northern Pintails (Anas acuta), typically feed by “tipping-up” (Bellrose, Ducks, Geese, and Swans of North America, Stackpole Books, Harrisburg, Pennsylvania, 1976) in shallow water. Pintails are not as adapted for diving as members of Aythyini or Oxyurini (Catlett and Johnston, Comp. Biochem. Physiol. 47A:925-931, 1974); however,...
Surveyors, cartographers, photogrammetrists; identification friends or foes
Frederick J. Doyle
1983, Cartography (13) 88-95
Largely because of historical developments, the disciplines of geodesy, surveying, photogrammetry, cartography and remote sensing which make up the profession of cartographic science are organised into numerous societies at both the national and international levels. Partly as a consequence of this separatism, an effective education system for the profession is...
Anaerobic oxalate degradation: Widespread natural occurrence in aquatic sediments
Richard L. Smith, Ronald S. Oremland
1983, Applied and Environmental Microbiology (46) 106-113
Significant concentrations of oxalate (dissolved plus particulate) were present in sediments taken from a diversity of aquatic environments, ranging from 0.1 to 0.7 mmol/liter of sediment. These included pelagic and littoral sediments from two freshwater lakes (Searsville Lake, Calif., and Lake Tahoe, Calif.), a hypersaline, meromictic,...

The paleoclimatic and paleoceanographic history has been studied in a N-S transect encompassing DSDP Site 173, the Newport Beach surface section, and DSDP Site 470, based on quantitative diatom and planktic foraminiferal analyses. Fourteen cold and 12 warm events that show close agreement with other microfossil studies as well as...
Eruptive history of Mount Mazama and Crater Lake Caldera, Cascade Range, U.S.A.
C. R. Bacon
1983, Journal of Volcanology and Geothermal Research (18) 57-115
New investigations of the geology of Crater Lake National Park necessitate a reinterpretation of the eruptive history of Mount Mazama and of the formation of Crater Lake caldera. Mount Mazama consisted of a glaciated complex of overlapping shields and stratovolcanoes, each of which was probably active for a comparatively short...
Dual extraction of R-mode and Q-mode factor solutions
D. Zhou, T. Chang, J.C. Davis
1983, Journal of the International Association for Mathematical Geology (15) 581-606
It is mathematically possible to extract both R-mode and Q-mode factors simultaneously (RQ-mode factor analysis)by invoking the Eckhart-Young theorem. The resulting factors will be expressed in measures determined by the form of the scalings that have been applied to the original data matrix. Unless the measures for both solutions are...
Analysis of spurious oscillation modes for the shallow water and Navier-Stokes equations
Roy A. Walters, G. F. Carey
1983, Computers and Fluids (11) 51-68
The origin and nature of spurious oscillation modes that appear in mixed finite element methods are examined. In particular, the shallow water equations are considered and a modal analysis for the one-dimensional problem is developed. From the resulting dispersion relations we find that the spurious modes in elevation are associated...
Tuffaceous sediments as source rocks for uranium: A case study of the White River Formation, Wyoming
R. A. Zielinski
1983, Journal of Geochemical Exploration (18) 285-306
Fine-grained tuffaceous sediments of the White River Formation (Oligocene) are evaluated as a possible source of uranium for the sedimentary uranium deposits of Wyoming. The evaluation is based upon a model in which volcanic glass is considered to be a major host of uranium and thorium and in which uranium...
Isotopic and chemical composition of Parbati Valley geothermal discharges, north-west Himalaya, India
W.F. Giggenbach, R. Gonfiantini, B.L. Jangi, A.H. Truesdell
1983, Geothermics (12) 199-222
The isotopic compositions of the waters discharged from Parbati Valley geothermal areas indicate a higher altitude meteoric origin, with discharge temperatures reflecting variations in the depth of penetration of the waters to levels heated by the existence of a ‘normal’ geothermal gradient. On the basis of mixing models involving silica,...
Distribution of mineral deposits in accreted terranes and cratonal rocks of western United States
J. P. Albers
1983, Canadian Journal of Earth Sciences (20) 1019-1029
The western margin of the conterminous United States, covering roughly 300 000 mi2 (777 000 km2), is an agglomeration of tectonostratigraphic terranes accreted to the North American craton mainly during Mesozoic time. The terranes represent a number of fundamental crustal types: oceanic crust, island-arc crust, mélange, various combinations of the preceding three, batholithic, miogeoclinal, and...

Conjunctive use of groundwater and surface water for irrigated agriculture: Risk aversion
John D. Bredehoeft, Richard A. Young
1983, Water Resources Research (19) 1111-1121
In examining the South Platte system in Colorado where surface water and groundwater are used conjunctively for irrigation, we find the actual installed well capacity is approximately sufficient to irrigate the entire area. This would appear to be an overinvestment in well capacity. In this paper we examine to what...
A quantitative comparison of Soil Development in four climatic regimes
J.W. Harden, E. M. Taylor
1983, Quaternary Research (20) 342-359
A new quantitative Soil Development Index based on field data has been applied to chronosequences formed under different climatic regimes. The four soil chronosequences, developed primarily on sandy deposits, have some numeric age control and are located in xeric-inland (Merced, Calif.), xeric-coastal (Ventura, Calif.), aridic (Las Cruces, N. Mex.), and...
