  • 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...

  • 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...

  • 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...

  • 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...

  • Relationships between thermal and electrical conductivities of ocean sediments and consolidated rocks

    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...

  • 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...

  • 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...

  • Fungal Secondary Metabolism of Basidiobolus meristosporus: a Novel Natural Product Reservoir

    Creator:
    Trautman, Ian A.
    Abstract:
    Secondary metabolites (SMs) play an integral role in the life history of most fungal species. Fungal metabolomic studies provide insights into how fungi perform certain ecological functions, how they compete and interact with other organisms, and the breadth of fungal chemodiversity. Fungal SMs have also been utilized for a variety...

  • Genome Organization in the Ectomycorrhizal Truffle Rhizopogon vesiculosus

    Creator:
    Lu, Dabao Sun
    Abstract:
    Rhizopogon vesiculosus is a common ectomycorrhizal (EM) symbiont of Pseudotusga menziesii (Douglas-fir) in the coast range of the Pacific Northwest. The species has been studied for its systematics, genet size, population structure, and competitive ability in several field and experimental studies. This thesis seeks to provide a more thorough characterization...

  • Nonlinear dynamic response of bottom-land deep ocean pipelines

    Creator:
    Zimmerman, Michael E.
    Abstract:
    A finite element formulation is developed for the prediction of the large displacement response of pipelines which are placed upon irregularly contoured marine sediments and are subsequently subjected to episodic hydrodynamic loads. The equations of motion during each episode of extreme wave activity are obtained from a variational form of...
