Absolute calibration of Landsat instruments using the moon.
H. H. Kieffer, R.L. Wildey
1985, Photogrammetric Engineering and Remote Sensing (51) 1391-1393
A lunar observation by Landsat could provide improved radiometric and geometric calibration of both the Thematic Mapper and the Multispectral Scanner in terms of absolute radiometry, determination of the modulation transfer function, and sensitivity to scattered light. A pitch of the spacecraft would be required. -Authors...
Lacustrine-humate model for primary uranium ore deposits, Grants uranium region, New Mexico
C. E. Turner-Peterson
1985, American Association of Petroleum Geologists Bulletin (69) 1990-2020
Two generations of uranium ore, primary and redistributed, occur in fluvial sandstones of the Upper Jurassic Morrison Formation in the San Juan basin; the two stages of ore formation can be related to the hydrologic history of the basin. Primary ore formed soon after Morrison deposition, in the Late Jurassic...
Drainage development of the Green River Basin in southwestern Wyoming and its bearing on fish biogeography, neotectonics, and paleoclimates.
W. R. Hansen
1985, Mountain Geologist (22) 192-204
The Upper Green River flows southward out of the Green River Basin through a series of deep canyons across the Uinta Mountains in a course that post-dates the deposition of the Bishop Conglomerate (Oligocene). After the Eocene lakes disappeared, drainage was generally eastward across the present Continental Divide, until the...
Geohydrology of the aquifer in the Santa Fe Group, northern West Mesa of the Mesilla Basin near Las Cruces, New Mexico
R. G. Myers, B. R. Orr
1985, Water-Resources Investigations Report 84-4190
Because of the heterogeneity of the Santa Fe Group, New Mexico, the hydrologic characteristics of the aquifer vary substantially from place to place. Hydraulic conductivities of 12 and 30 feet per day were estimated from aquifer tests for two wells in the eastern one-half of the study area. Well yields...
Atlantic Flyway review: Region V: Laurel, Prince Georges County, MD (390-0765)
Chandler S. Robbins
1985, North American Bird Bander (10) 56-56
My being away nearly all of September and on half the October weekends cut deeply into this season's banding. Totals for permanent residents and winter residents were close to normal, but numbers of the transient species are not at all comparable with other years. The only species that seemed more...

Altered energy metabolism in an irradiated population of lizards at the Nevada Test Site
K.A. Nagy, P.A. Medica
1985, Radiation Research (103) 98-104
Field metabolic rates (via doubly labeled water), body compartmentalization of energy stores, and energy assimilation efficiencies were measured to assess all avenues of energy utilization in Uta stansburiana living in a low-level γ-irradiated plot in Rock Valley, Nevada. Comparison of energy budgets for radiation-sterilized females with those of nonirradiated control...
Maneuverability of the Humboldt penguin (Spheniscus humboldti) during swimming
Clifford A. Hui
1985, Canadian Journal of Zoology (63) 2165-2167
Analyses of high-speed film of captive Humboldt penguins (Spheniscus humboldti) show that there is no correlation between the radii of submerged turns and swimming speed. The sharpest turns had a mean turn radius (n = 5) of 0.14 m (0.24 body lengths), were powered by beating wings, and used multiple steering structures (beak,...
Classification of wetlands and deepwater habitats of the United States
L.M. Cowardin, V. Carter, F.C. Golet, E.T. LaRoe
1985, FWS/OBS 79/31
This classification, to be used in a new inventory of wetlands and deepwater habitats of the United States, is intended to describe ecological taxa, arrange them in a system useful to resource managers, furnish units for mapping, and provide uniformity of concepts and terms. Wetlands are defined by plants (hydrophytes),...
Tolerance of West Indian manatees to capture and handling
T. J. O'Shea, G. B. Rathbun, E.D. Asper, S.W. Searles
1985, Biological Conservation (33) 335-349
Ninety-two West Indian manatees (Trichechus manatus) have been captured in the southeastern United States from October 1975 through November 1983 with no evidence of an unusual susceptibility to capture myopathy. Of these, 53 were radio-tracked or observed in the field following capture with no evidence of delayed capture stress. Blood samples obtained...
Active tectonic and magmatic processes beneath Long Valley Caldera, eastern California: An overview
D.P. Hill, R. A. Bailey, A.S. Ryall
1985, Journal of Geophysical Research Solid Earth (90) 11111-11120
Geological, chronological, and structural studies of the Long Valley-Mono/Inyo Craters area document a long history of related volcanic eruptions and earthquakes controlled by regional extensional tectonics of the Basin and Range province. This activity has persisted for hundreds of thousands of years and is likely to continue. The Long Valley...
PROGRESS REPORT ON GEOLOGIC STUDIES OF THE RANGER OREBODIES, NORTHERN TERRITORY, AUSTRALIA.
J. Thomas Nash, David Frishman
Sibbald T.I.I.Petruk William, editor(s)
1985, Conference Paper, CIM Special Volume
The Ranger No. 1 and No. 3 orebodies contain about 124,000 tonnes U//3O//8 in highly chloritized metasediments of the lower Proterozoic Cahill Formation within about 500 m of the projected sub-Kombolgie Formation unconformity. In both orebodies, oxidized and reduced uranium minerals occur chiefly in quartzose schists that have highly variable...
Role of small oil and gas fields in the United States
Richard F. Meyer, Mary L. Fleming
1985, American Association of Petroleum Geologists Bulletin (69) 1950-1962
With the maturation of oil and gas production operations in a province or country, fields found by new-field wildcats diminish in size. The actual economic size cutoff is a function of such factors as depth, water depth offshore, and accessibility to transportation infrastructure. Because of the constraint of resource availability,...
Tidal variation of seismic travel times in a Massachusetts granite quarry
Hsi-Ping Liu, Eugene D. Sembera, Robert E. Westerlund, Jon B. Fletcher, Paul Reasenberg, Duncan C. Agnew
1985, Geophysical Research Letters (12) 243-246
Conflicting results on tidal variation of seismic travel times exist in the literature. With improved methods, we have conducted a seismic survey at a Massachusetts granite quarry. The survey was conducted in the intervals (230d 23h, 231d11h) and (231d22h, 233d10h), 1983 (U.T.) along a 148 m...
Maximum likelihood estimation for periodic autoregressive moving average models
A. V. Vecchia
1985, Technometrics (27) 375-384
A useful class of models for seasonal time series that cannot be filtered or standardized to achieve second-order stationarity is that of periodic autoregressive moving average (PARMA) models, which are extensions of ARMA models that allow periodic (seasonal) parameters. An approximation to the exact likelihood for Gaussian PARMA processes is...
Separation of solute and particulate vectors of heavy metal uptake in controlled suspension-feeding experiments with Macoma balthica
Ronald W. Harvey, Samuel N. Luoma
1985, Hydrobiologia (121) 97-102
Radioisotope labelling experiments with the estuarine clam, Macoma balthica, are described, in which a filter chamber device was used to separate solute metal uptake from uptake, of metals associated with suspended bacteria. Solute uptake contributed a majority of the 14-day total body burdens of 65Zn and 109Cd, whereas 57Co uptake...
The effect of glaciers on streamflow variations
Andrew G. Fountain, Wendell V. Tangborn
1985, Water Resources Research (21) 579-586
The effect of temperate glaciers on runoff variations is examined for the North Cascade Mountains of Washington State. The principal influences of glaciers on streamflow are often unexpected contributions to streamflow volume, a delay of the maximum seasonal flow, and a decrease in annual and monthly variation of runoff. The...

Ages of tuff beds at East African early hominid sites and sediments in the Gulf of Aden
A.M. Sarna-Wojcicki, C.E. Meyer, P.H. Roth, F. H. Brown
1985, Nature (313) 306-308
The early hominids of East Africa were dated by determining the ages of tuff beds at the sites. Despite much research using palaeomagnetic and K/Ar-dating techniques, some of those ages are still controversial 1,2. To obtain independent age estimates for these tephra layers, we have examined cores from DSDP Sites...
Spatial analysis of extension fracture systems: A process modeling approach
C.C. Ferguson
1985, Journal of the International Association for Mathematical Geology (17) 403-425
Little consensus exists on how best to analyze natural fracture spacings and their sequences. Field measurements and analyses published in geotechnical literature imply fracture processes radically different from those assumed by theoretical structural geologists. The approach adopted in this paper recognizes that disruption of rock layers by layer-parallel extension results...
