Acoustic-reflection profiles, Bay of Campeche: International Decade of Ocean Exploration, U.S. Geological Survey, Leg 1, 1971 cruise, UNITEDGEO I
George William Moore
1972, Report
IntroductionAs part of a cooperative marine research program designated the International Decade of Ocean Exploration (IDOE), the United States Geological Survey is participating in an investigation of the geologic framework and resource potential of continental margins and small ocean basins in the Gulf of Mexico, Caribbean Sea, and west African...
Avian cholera in cedar waxwings in Ohio
L. N. Locke, R.C. Banks
1972, Journal of Wildlife Diseases (8) 106-106
Avian cholera (Pasteurella multocida infection) was responsible for a localized die-off of cedar waxwings (Bombycilla cedrorum) at Steubenville, Ohio in late June, 1968....
A repellent for protecting corn seed from blackbirds and crows
A.R. Stickley Jr., J.L. Guarineo
1972, Journal of Wildlife Management (36) 150-152
Methiocarb [4-(methylthio)-3,-5-xylyl N-methylcarbamate] was tested as a seed treatment for repelling blackbirds and crows (Corvus sp.) from sprouting corn in South Carolina. The test was conducted on eight fields within a 0.25-square-mile area. Marked repellency occurred; sprout damage averaged 44 percent in the control fields and 0.3 percent in the...
Biscalitheca suzanneana, N. Sp., from the uppermost Pennsylvanian of Texas
S.H. Mamay
1972, Review of Palaeobotany and Palynology (14) 141-147
Biscalitheca suzanneana, n. sp., is described from specimens found in an uppermost Pennsylvanian deposit in north-central Texas. The genus was identified primarily on the basis of impressions of the unique sporangial annuli. The occurrence establishes for Biscalitheca a stratigraphic range equivalent to nearly the entire...
Site distribution of iron in staurolite
Eric Dowty
1972, Earth and Planetary Science Letters (15) 72-74
The Mössbauer spectrum of staurolite does not necessarily indicate that ferrous iron is distributed over both the tetrahedral Fe site and one or more of the octahedral sites, as previously thought. Two doublets are present in the spectrum, but their quadrupole spliting...
New data on selected Ivory Coast tektites
F. Cuttitta, M. K. Carron, C. S. Annell
1972, Geochimica et Cosmochimica Acta (36) 1297-1309
Fourteen Ivory Coast tektites exhibit a range of bulk indices of refraction of 1.5156 to 1.5217 ± 0.0004 and of bulk specific gravities of 2.428 to 2.502 ±0.005. Seven of these Ivory Coast (IVC) tektites were analyzed for major and minor element content. Compared to tektites from other strewn fields,...
Microcoulometric measurement of water in minerals
M. Cremer, H.N. Elsheimer, E.E. Escher
1972, Analytica Chimica Acta (60) 183-192
A DuPont Moisture Analyzer is used in a microcoulometric method for determining water in minerals. Certain modifications, which include the heating of the sample outside the instrument, protect the system from acid gases and insure the conversion of all hydrogen to water vapor. Moisture analyzer...
Oil development and conservation in Arctic America
J. C. Reed
1972, Biological Conservation (4) 369-371
As in his earlier article to which reference is made, the author stresses the need for more background information and a much greater research effort before problems of environmental protection from oil developments in northern Alaska can be effectively tackled. Meanwhile, there...
Geological framework of the south polar region of Mars
B. C. Murray, L.A. Soderblom, J.A. Cutts, R.P. Sharp, D.J. Milton, R.B. Leighton
1972, Icarus (17) 328-345
The first 4 months of Mariner 9 photography of the south polar region are discussed. Three major geological units have been recognized, separated by erosional unconformities. From oldest to youngest they are: cratered terrain, pitted plains, and laminated terrain. The latter unit is unique in occurrence to the polar region,...
Imogolite and allophane formed in saprolite of basalt on Maui, Hawaii
K. Wada, T. Henmi, N. Yoshinaga, S. H. Patterson
1972, Clays and Clay Minerals (20) 375-380
Inorganic gel and allophane collected from basaltic saprolite on Maul, Hawaii, and studied by Patterson in I964 were reexamined. The main constituent of the gel is imogolite, and gibbsite and allophane are the minor constituents. Electron and X-ray diffraction patterns, DTA curve, and an infrared spectrum of the gel are...
Imaging experiment: The Viking Mars orbiter
M. H. Carr, W.A. Baum, G.A. Briggs, H. Masursky, D.W. Wise, D. R. Montgomery
1972, Icarus (16) 17-33
The general objectives of the Imaging Experiment on the Viking Orbiter are to aid the selection of Viking Lander sites, to map and monitor the chosen sites during lander operations, to aid in the selection of future landing sites, and to extend our...
The martian atmosphere: Mariner 9 television experiment progress report
C.B. Leovy, G.A. Briggs, A.T. Young, B.A. Smith, James B. Pollack, E.N. Shipley, R.L. Wildey
1972, Icarus (17) 373-393
Atmospheric phenomena appearing in the Mariner 9 television pictures are discussed in detail. The surface of the planet was heavily obscured by a global dust storm during the first month in orbit. Brightness data during this period can be fitted by a semi-infinite...
Radiative-neutron-capture gamma-ray analysis by a linear combination technique
A.B. Tanner, R.C. Bhargava, F. E. Senftle, J.M. Brinkerhoff
1972, Nuclear Instruments and Methods (102) 61-72
The linear combination technique, when applied to a gamma-ray spectrum, gives a single number indicative of the extent to which the spectral lines of a sought element are present in a complex spectrum. Spectra are taken of the sought element and of various...
Fluorination of 1,2,3-, 1,2,4-, and 1,3,5-trihalobenzenes with potassium fluoride in dimethyl sulfone
R.H. Shiley, D. R. Dickerson, G. C. Finger
1972, Journal of Fluorine Chemistry (2) 19-26
Three trifluorobenzenes were prepared by reaction of the corresponding trichlorobenzenes with potassium fluoride or pottassium fluoride-cesium fluoride mixtures in dimethyl sulfone. Molar yields were 12.8% for 1,2,3-, 8.3% for 1,2,4-, and 56.2% for 1,3,5-. Improved yields of the 1,2,3- (23.9%) and the 1,2,4-...
