The Television Experiment objectives are to provide imaging data which will complement previously gathered data and extend our knowledge of Mars. The two types of investigations will be fixed-feature (for mapping) and variable-feature (for surface and atmospheric changes). Two cameras with a factor-of-ten difference in resolution will be used on...
Foraminiferal zonation and carbonate facies of Carboniferous (Mississippian and Pennsylvanian) Lisburne group, central and eastern Brooks range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro
1970, American Association of Petroleum Geologists Bulletin (54) 687-698
The Lisburne Group carbonate rocks of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of late Tournaisian (Osage) to early Moscovian (Atoka) age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as well as with...

Z. E. Peterman, C. E. Hedge, H. A. Tourtelot
1970, Geochimica et Cosmochimica Acta (34) 105-120
Isotopic analyses of strontium in primary fossil carbonate reveal significant variations in Sr87Sr86">Sr87Sr86 of sea water during the Phanerozoic. The strontium isotopic composition may have been uniform from the Ordovician through the Mississippian, with an average Sr87Sr86">Sr87Sr86 of 0.7078. A subsequent decrease...
Strontium isotopes in some Cenozoic lavas from Oregon and Washington
C. E. Hedge, R.A. Hildreth, W.T. Henderson
1970, Earth and Planetary Science Letters (8) 434-438
The87Sr/86Sr ratios have been determined in 22 volcanic rocks from Oregon and Washington. The emphasis of the study was on andesites and dacites, but several basalts were included. Most of the samples have a very limited range in strontium isotopic composition...
Effects of oil development in Arctic America
J. C. Reed
1970, Biological Conservation (2) 273-277
Large and important discoveries of petroleum were made in northern Alaska in 1968. The reserves were estimated then to be perhaps as much as ten thousand million barrels. Subsequent exploration has shown the resources to be much greater than was estimated earlier. Many...
Isotopic investigations of xenoliths and host basalts from the Honolulu volcanic series
J. R. O’Neil, C. E. Hedge, E.D. Jackson
1970, Earth and Planetary Science Letters (8) 253-257
Oxygen, carbon and strontium isotope ratios point to a ground-water origin for the carbonates found in Hawaiian Volcanic Series rocks. Strontium isotope ratios in the xenoliths and host basalts indicate a genetic relationship between them....

G. G. Schaber, R. E. Eggleton, T.W. Thompson
1970, Nature (226) 1236-1239
DELAY-DOPPLER radar maps of the Moon obtained with the 430 MHz (70 cm wavelength) radar of the Arecibo Ionospheric Observatory in Puerto Rico (Thompson, unpublished) are at present being studied to correlate geological information with the radar reflexion characteristics of the lunar surface. Preliminary evaluation of...
Neutron radiative capture methods for surface elemental analysis
J.I. Trombka, F. Senftle, R. Schmadebeck
1970, Nuclear Instruments and Methods (87) 37-43
Both an accelerator and a 252Cf neutron source have been used to induce characteristic gamma radiation from extended soil samples. To demonstrate the method, measurements of the neutron-induced radiative capture and activation gamma rays have been made with both Ge(Li) and NaI(Tl) detectors, Because...
Jurassic (callovian) paleotemperatures from Scotland
F.C. Tan, J.D. Hudson, M.L. Keith
1970, Earth and Planetary Science Letters (9) 421-426
Isotopic paleotemperature analyses of belemnites and ammonites from the Belemnite Sands and Oxford Clay of Staffin Bay, Isle of Skye, are presented. Ammonites are depleted in18O compared with co-existing belemnites, which give mean temperatures of around 22°C, consistent with the Skye belemnite...
GLC determination of quinaldine residue in fish
J. L. Allen, J.B. Sills
1970, Journal of the Association of Official Analytical Chemists (53) 20-23
A procedure for the determination of quinaldine residue in various fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether, the extracts are concentrated by partitioning through 0.1N sulfuric acid, and the residues are measured by alkali flame ionization gas chromatography. Muscle tissues containing from 0.01 to 10.0 ppm quinaldine...
UV identification and quantitative measurement of quinaldine residues in fish
J. L. Allen, J.B. Sills
1970, Journal of the Association of Official Analytical Chemists (53) 1170-1171
A method for the confirmatory analysis of quinaldine residue in fish is described. The method utilizes the same extraction and cleanup procedure as the GLC method reported previously. The lower limit of sensitivity for quinaldine residue in fish muscle is 0.01 ppm. Identification is accomplished by comparing the UV spectra...
Salmonid viruses: Double infection of RTG-2 cells with Egtved and infectious pancreatic necrosis viruses
K. Wolf, P. E. Vestergard Jorgensen
1970, Archiv Fur Die Gesamte Virusforschung (29) 337-342
Egtved and infectious pancreatic necrosis (IPN) viruses were applied at high multiplicity alone and in combination to RTG-2 cells in liquid medium. Procedures were used which selectively suppressed one or the other virus, and the yields were determined after 64 hours at 15°C. The viruses showed an increase of 280...
Analytical sensitivities and energies of thermal-neutron-capture gamma rays

1970, Nuclear Instruments and Methods (80) 149-171
A table of the analytical sensitivities of the principal lines in the thermal-neutron-capture gamma ray spectrum has been compiled for most of the elements. In addition a second table of the full-energy, single-escape, and double-escape peaks has been compiled according to energy for...

Young-of-the-year ciscoes (Coregonus artedii) acclimated to 2, 5, 10, 20 and 25 C and tested for tolerance to high and low temperatures provide the first detailed description of the thermal tolerance of coregonids in North America. The upper ultimate lethal temperature of the young ciscoes was 26 C (6 C...

Walleye fishery of Lake Erie in 1943-62 with emphasis on contributions of the 1942-61 year-classes
John W. Parsons
1970, Journal of the Fisheries Research Board of Canada (27) 1475-1489
The commercial fishery for walleyes (Stizostedion vitreum vitreum) in Lake Erie virtually collapsed in the late 1950's. The extreme decline in production was attributed primarily to a succession of weak year-classes, caused by habitat deterioration (increased water temperatures, enrichment, and pollution) in western Lake Erie. Unusually high fishing intensity and...

Lithium metaborate flux in silicate analysis
C.O. Ingamells
1970, Analytica Chimica Acta (52) 323-334
Lithium metaborate is an effective flux for silicates and other rock-forming minerals. The glass resulting from fusion is mechanically strong, reasonably nonhygroscopic, and is readily soluble in dilute acids. These characteristics lead to its use in X-ray spectrography and in methods which require whole-rock solutions,...
Use of microearthquakes in the study of the mechanics of earthquake generation along the San Andreas fault in central California
J. P. Eaton, W.H.K. Lee, L. C. Pakiser
1970, Tectonophysics (9) 259-282
A small, dense network of independently recording portable seismograph stations was used to delineate the slip surface associated with the 1966 Parkfield-Cholame earthquake by precise three dimensional mapping of the hypocenters of its aftershocks. The aftershocks were concentrated in a very narrow vertical zone beneath or immediately adjacent to the...

The diffusion of ions in unconsolidated sediments
F.T. Manheim
1970, Earth and Planetary Science Letters (9) 307-309
Diffusion in unconsolidated sediments generally proceeds at rates ranging from half to one twentieth of those applying to diffusion of ions and molecules in free solution. Diffusion rates are predictable with respect to porosity and path tortuosity in host sediments, and can be conveniently measured by determinations of electrical resistivity...
