Deuterium content of snow as an index to winter climate in the Sierra Nevada area
I. Friedman, G.I. Smith
1972, Science (176) 790-793
The winter of 1968-69 produced two to three times the amount of precipitation in the Sierra Nevada area, California and Nevada, as the winter of 1969-70. The deuterium content in snow cores collected at the end of each winter at the same sites, which represents the total snowfall of each...
Preliminary mariner 9 report on the geology of Mars
John F. McCauley, M. H. Carr, J.A. Cutts, W.K. Hartmann, Harold Masursky, D.J. Milton, R.P. Sharp, Don E. Wilhelm
1972, Icarus (17) 289-327
Mariner 9 pictures indicate that the surface of Mars has been shaped by impact, volcanic, tectonic, erosional and depositional activity. The moonlike cratered terrain, identified as the dominant surface unit from the Mariner 6 and 7 flyby data, has proven to be less typical of Mars than previously believed, although...
Red fox spatial characteristics in relation to waterfowl predation
A.B. Sargeant
1972, Journal of Wildlife Management (36) 225-236
Radio-equipped red foxes (Vulpes vulpes) on the Cedar Creek area in Minnesota were spatially distributed, with individual families occupying well defined, nonoverlapping, contiguous territories. Territory boundaries often conformed to natural physical boundaries and appeared to be maintained through some nonaggressive behavior mechanism. Individual foxes traveled extensively throughout the family territory...
Techniques for establishing local breeding populations of wood ducks
Harold A. Doty, A.D. Kruse
1972, Journal of Wildlife Management (36) 428-435
A study was conducted on the Arrowwood National Wildlife Refuge in east-central North Dakota to further evaluate a technique for establishing nesting wood ducks (Aix sponsa) by releasing propagated birds and installing nest houses. No wood duck nesting had been recorded previously in the area. During May-July 1968, 253 ducklings,...
Some physiologic blood values of wild diving ducks
R. M. Kocan
1972, Journal of Wildlife Diseases (8) 115-118
Blood samples were obtained from 54 canvasbacks (Aythya valisineria), 30 lesser scaup (A. affinis), 3 ring-necks (A. collaris), and 3 buffleheads (Bucephala albeola), which were wintering on Chesapeake Bay. These blood samples were used for: red blood cell counts (cans. 2.56 × 106/mm3;...
Immunologic status of mourning doves following an epizootic of trichomoniasis
R. M. Kocan, S.R. Amend
1972, Journal of Wildlife Diseases (8) 176-180
An epizootic of trichomoniasis in mourning doves at the Carolina Sandhills National Wildlife Refuge began in 1969 and continued into 1970. The disease was seen in 16% of the adults and 2% of the immatures in 1970, but only one immature bird out of 37 surveyed (3%) carried Trichomonas gallinae. Challenge...
Magnetic noise preceding the August 1971 summit eruption of Kilauea Volcano
G.V. Keller, D. B. Jackson, A. Rapolla
1972, Science (175) 1457-1458
During the course of an electromagnetic survey about Kilauea Volcano in Hawaii, an unusual amount of low-frequency noise was observed at one recording location. Several weeks later an eruption occurred very close to this site. The high noise level appeared to be associated in some way with the impending eruption....
Nimbus IV view of the major structural features of Alaska
E. H. Lathram
1972, Science (175) 1423-1427
Notwithstanding the relatively low degree of ground resolution, many of the major structural features of Alaska can be identified on the Nimbus IV IDCS image, exposed at an altitude of 600 nautical miles (1100 km). In addition, linears of regional extent that may be structurally controlled can be seen, many...
Geology of the massive sulfide deposits at Jerome, Arizona; A reinterpretation
C.A. Anderson, J. Thomas Nash
1972, Economic Geology (67) 845-863
The massive sulfide deposits at Jerome, consisting largely of pyrite, chalcopyrite, and sphalerite, are concordant stratabound lenses in massive quartz-bearing crystal tuffs of Precambrian age and overlying bedded tuffaceous rocks. The crystal tuffs were eraplaced as submarine pyroclastic flows. The evidence permits the interpretation that the massive sulfide lenses are...
An approach to the design of statewide or regional ground water information systems
Thomas C. Winter
1972, Water Resources Research (8) 222-230
The design of water information or basic data systems must be flexible enough to provide information and data for a broad range of interests from national to local. The system must satisfy the need for information for accounting, surveillance, and areal synthesis purposes. The network is designed by identifying specific...
Suspended matter in surface waters of the northern Gulf of Mexico
Frank T. Manheim, J.C. Hathaway, Elazar Uchupi
1972, Limnology and Oceanography (17) 17-27
Analyses of about 200 surface water samples collected during late fall 1966 show that concentrations of suspended matter greater than 1 mg/liter were restricted to within a few kilometers off Florida, but extended more than 100 km off Louisiana and Texas. Suspensates from areas farther than 100 km from shore...
Mariner 9 television reconnaissance of Mars and its satellites: Preliminary results
H. Masursky, R. M. Batson, J.F. McCauley, L.A. Soderblom, R.L. Wildey, M. H. Carr, D.J. Milton, D.E. Wilhelms, B.A. Smith, T.B. Kirby, J.C. Robinson, C.B. Leovy, G.A. Briggs, T. C. Duxbury, C.H. Acton Jr., B. C. Murray, J.A. Cutts, R.P. Sharp, S. Smith, R.B. Leighton, C. Sagan, J. Veverka, M. Noland, J. Lederberg, E. Levinthal, James B. Pollack, J.T. Moore Jr., W.K. Hartmann, E.N. Shipley, G. De Vaucouleurs, M. E. Davies
1972, Science (175) 294-305
At orbit insertion on 14 November 1971 the Martian surface was largely obscured by a dust haze with an extinction optical depth that...
Borehole activation analysis by delayed and capture gamma rays using a 252Cf neutron source
R.M. Moxham, F. E. Senftle, G. R. Boynton
1972, Economic Geology (67) 579-591
Theoretical analysis and experimental comparison of the radiative capture and delayed gamma-ray activation techniques indicate the latter to be more efficient for the detection of copper, whereas the radiative capture method is preferable for nickel. A conservative lower detection limit for both copper and nickel is '-0.5%. Borehole spectra by...
Annual water-resources review, White Sands Missile Range: 1971
R. R. Cruz
1972, Report
This report presents water-resource information that was collected at White Sands Missile Range during 1971 and early 1972 by personnel of the U.S. Geological Survey, Water Resources Division. Data on ground-water pumpage and resulting water-level fluctuation, chemical quality, percipitation, and surface-water runoff are summarized in the report. The data were...
Distribution and isotopic composition of uranium in lower Nueces River, Nueces Bay and Corpus Christi Bay, Texas
Charles W. Holmes, Elizabeth Ann Slade
1972, Gulf Coast Association of Geological Societies Transactions (22) 315-322
The uranium concentration and isotopic composition of water and suspended sediment from the Nueces River, Nueces Bay and Corpus Christi Bay were determined by alpha-spectroscopy. The average dissolved uranium concentration and radioactivity ratio (U234/U238) of Nueces River water were determined to be 2.44 µg/1 and 1.15 respectively. Water from a...
