  • Marine seismic studies near Newport, Oregon

    Creator:
    Erickson, Barrett H.
    Abstract:
    In July 1964 three seismic refraction profiles were recorded over Stonewall Bank (44°32'N, 124°24'W) to determine gross sub-bottom geological structure to depths of thousands of feet. In August 1964 a continuous seismic reflection profiler was used to document shallow geological structure within the rocks forming the Bank. Stonewall Bank is...

  • Marine geophysical studies offshore: Newport, Oregon

    Creator:
    Whitcomb, James Hall
    Abstract:
    A marine geophysical study using shallow seismic reflection, gravity and magnetic methods of investigation was done for an offshore area near Newport, Oregon. The area is bounded by the latitudes 44°1O' to 44°50' N. and longitudes 124°07' to 124°30' W. The interpretation of observational data showed that the geology of...

  • Attenuation of compressional waves in the earth's mantle

    Creator:
    Sarmah, Suryya Kanta
    Abstract:
    Fourier transformed amplitudes of the compressional waves recorded between 9° and 91° (about 1000 to 10,000 km) epicentral distance from Gnome, Shoal, Haymaker,and Bilby underground nuclear explosions have been compared with Fourier transformed amplitudes of P waves measured at distances between 9.0 and 1 3. 0 km from the explosions....

  • Transmission and attenuation of the primary seismic wave, [delta]=100 to 600 KM

    Creator:
    Long, L. T. (Leland Timothy)
    Abstract:
    The character of the primary seismic wave in the range of distances between 100 and 600 km is affected by such factors as the nature of the source, exponential attenuation, crustal structure, type of wave propagation, recording site geology and instrument response. The first arrivals from the GNOME and SHOAL...

  • Primary seismic wave (P) at 250-350 km compared to measured wave to 0.3 km from GNOME nuclear explosion

    Creator:
    Laun, Philip Royal
    Abstract:
    The first cycle of seismic waves recorded at distances of 45, 300 and 355 km. from the GNOME nuclear explosion was used to determine whether the near source wave characteristics at 0.3 km. could be determined from distance measurements. Both head wave and body wave propagation were considered. First the...

  • Gravity interpretation using the Fourier integral

    Creator:
    Odegard, Mark Erie
    Abstract:
    The gravitational anomalies of simple bodies (sphere, cylinder, and fault) were used to develop methods for analyzing gravity data in the frequency domain. The Fourier transforms of the functional representations of the theoretical gravitational anomalies of these bodies were obtained. Mathematical formulations were made between the transform versus frequency relationships...

  • Angle of emergence of seismic P waves and its variation with frequency

    Creator:
    Souders, Robert Hunter
    Abstract:
    The vertical and radial components of a seismic P wave can be decomposed by a Fourier transform into two sets of nonterminating sinusoidal waves with one set for each component. The tangent of the vertical transform divided by the radial transform gives by definition he apparent angle of emergence for...

    Creator:
    Hutt, Jeremy Reinboth
    Abstract:
    From measurements of thermal and electrical conductivities of 64 ocean sediment samples obtained from piston cores taken off the Oregon Coast, and from 37 water-saturated sandstone samples analyzed by Zierfuss and Van der Vliet (1956), as well as 51 thermal conductivities and water contents of ocean sediments analyzed by Ratcliffe...

  • Primary seismic waves near explosions

    Creator:
    Trembly, Lynn Dale
    Abstract:
    This thesis is concerned with near source primary seismic waves generated by, the Gnome, Hardhat, Shoal and Haymaker underground nuclear explosions. Records of ground motion between 0.3 and 20.0 kilometers from the sources were analyzed in terms of displacement amplitude and energy variations with distance. The observed data have been...
