Land use data were successfully interpreted...
From ecological test site to geographic information system: lessons for the 1980's
Robert H. Alexander
1981, Pecora VII Symposium 359-365
Geographic information systems were common elements in two kinds of interdisciplinary regional demonstration projects in the 1970's. Ecological test sits attempted to provide for more efficient remote-sensing data delivery for regional environmental management. Regional environmental systems analysis attempted to formally describe and model the interacting regional social and...
Compressing interpreted satellite imagery for geographic information systems applications over extensive regions
Stephan W. Miller
1981, Pecora VII Symposium 341-358
Image processing systems (IPS) and techniques effectively transform satellite imagery into data for input into a spatial database. Geographic information systems (GIS), consisting of graphic input and spatial database management subsystems, are capable of processing digital map and map overlay data to build and manipulate a spatial database. These systems...
Bobwhite population responses to exploitation: two problems
David R. Anderson, Kenneth P. Burnham
1981, Journal of Wildlife Management (45) 1052-1054
Recently, Roseberry (1979) attempted to (1) clarify the theoretical basis for harvesting bobwhite (Colinus virginianus), (2) assess the impact of varying intensities of harvest on standing densities and long-term yields, and (3) define a harvest strategy appropriate for the bobwhite resource in Illinois. That paper, based on 24 years...
The freshwater‐inflow‐to‐estuaries issue
Norman Gustaf Benson
1981, Fisheries (6) 8-10
Over 55% of the United States commercial fish and shellfish catch is dependent upon estuaries for spawning and nursery functions, but estuaries cannot function ecologically without an adequate supply, seasonal inflow, and quality of freshwater from inland rivers. Such inland river development projects as constructing reservoirs, leveeing rivers, dredging navigation...

Seawater consumption and water flux in the common dolphin Delphinus delphis
Clifford A. Hui
1981, Ecological and Evolutionary Physiology (54) 430-440
Two captive female common dolphins (59 kg and 55 kg) were given intravenous injections of tritiated water (HTO) and sodium-22 (Na-22) after the first day of a 5-day fast. Blood samples were collected each of the next 4 days. Total body water was 37% of total body weight, and the mean rate of <span...
Synchrotron radiation and its application to digital subtraction angiography
E. Rubenstein, E.B. Hughes, L.E. Campbell, R. Hofstadter, Randolph L. Kirk, T.J. Krolicki, J.P. Stone, S. Wilson, H.D. Zeman, W.R. Brody
1981, Conference Paper, Proceedings Volume 0314, Digital Radiography
The intense synchrotron radiation produced at electron storage rings provides a new source of X-rays highly suited to iodine K-edge digital subtraction angiography. The high intensity and small angular divergence permit the radiation to be monochromatized by Bragg diffraction and made available in beams of small vertical size, of arbitrary...
Economics and petroleum resource appraisal: The case of the Permian basin:
Emil D. Attanasi, T.M. Garland, J.H. Wood, William D. Dietzman, J.N. Hicks
1981, Journal of Petroleum Technology (33) 603-616
Estimates of oil and gas resources typically are presented in terms of proved and undiscovered resources. This paper presents a methodology for incorporating economic considerations into resource appraisals for petroleum basins. A cost algorithm is used to calculate estimates of the costs of finding and developing undiscovered oil and gas...
Organic geochemistry of the 9.6 km Bertha Rogers No. 1. well, Oklahoma
Leigh C. Price, Jerry L. Clayton, L.L. Rumen
1981, Organic Geochemistry (3) 59-77
Organic geochemical analyses of fine-grained rocks from the 9.590 km Bertha Rogers No. 1 well have been carried out: total organic carbon, Soxhlet extraction and silica gel chromatography, C15+ saturated and aromatic hydrocarbon gas chromatography and mass spectrometry, pyrolysis, kerogen analysis, X-ray diffraction and visual kerogen analysis.Rocks ranged in age from...

Uranium series dating of human skeletal remains from the Del Mar and Sunnyvale sites, California
J. L. Bischoff, R.J. Rosenbauer
1981, Science (213) 1003-1005
Uranium series analyses of human bone samples from the Del Mar and Sunnyvale sites indicate ages of 11,000 and 8,300 years, respectively. The dates are supported by internal concordancy between thorium-230 and protactinium-231 decay systems. These ages are significantly younger than the estimates of 48,000 and 70,000...

Crustal processes of the Mid-Ocean Ridge
Richard D. Ballard, H. Craig, J. Edmond, M. Einaudi, R. Holcomb, H.D. Holland, C.A. Hopson, B.P. Luyendyk, K. Macdonald, J. Morton, J. Orcutt, N. Sleep
1981, Science (213) 31-40
Independent geological and geophysical investigations of the Mid-Ocean Ridge system have begun to focus on the nature of the magma chamber system underlying its central axis. Thermal models predict the existence of a steady-state chamber beneath a thin crustal lid ranging in thickness from 2 to 13...
State of stress and intraplate earthquakes in the United States
Mark D. Zoback, Mary Lou Zoback
1981, Science (213) 96-104
Recently compiled data on the state of stress have been used to define stress provinces in the conterminous United States in which the orientation and relative magnitude of the horizontal principal stresses are fairly uniform. The observed patterns of stress constrain mechanisms for generating intraplate lithospheric stresses....
Processes controlling the characteristics of the surficial sand sheet, U.S. Atlantic outer continental shelf
Harley J. Knebel
1981, Marine Geology (42) 349-368
A review of recent data on the velocity of bottom currents, the frequency of bottom-sediment movement, the kinds and amounts of suspended sediments in near-bottom waters, and the acoustic and sedimentary features of subbottom strata indicates that the characteristics of the ubiquitous sand sheet on the Atlantic outer continental shelf...
Decline and present status of breeding Peregrine Falcons in Oregon
Charles J. Henny, M.W. Nelson
1981, Murrelet (62) 43-53
Unprecedented declines of the Peregrine Falcon (Falco peregrinus) throughout much of the Northern Hemisphere became apparent during the Madison Peregrine Falcon Conference in 1965 (Hickey 1969). Data from Britain were the most detailed; broken or missing eggs were much more common in 1949-56 than they had been in earlier years...

David J. Parsons, Thomas J. Stohlgren, Paul A. Fodor
1981, Environmental Management (5) 335-340
Increasing levels of visitor use and consequent resource damage have necessitated that backcountry use restrictions be established in the Mineral King area of Sequoia National Park, California. In this paper we review the steps taken in developing a trailhead quota system. The availability of acceptable campsites, based on a detailed...
