  • Consolidation characteristics of calcareous deep sea-floor sediments from the Panama Basin

    Creator:
    Kao, Yeoung Ting
    Abstract:
    Calcareous sediments containing a large percentage of foraminiferal microskeletal tests were taken from sites in the Panama Basin and subjected to an investigation to determine the consolidation characteristics of this type of soil. The consolidation-stress curves and the time rate of consolidation curves in particular were investigated in this study....

  • Effects of pressure and deposit thickness on the stabilization rate of benthic marine sludge deposits

    Creator:
    Muellenhoff, W. P.
    Abstract:
    The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....

  • Identification of structural parameters and hydrodynamic effects for forced and free vibration

    Creator:
    Kruchoski, Brian L. (Brian Louis)
    Abstract:
    Statistically-based estimation techniques are presented in this study. These techniques incorporate structural test data to improve finite element models used for dynamic analysis. Methods are developed to identify optimum values of the parameters of finite element models describing structures. The parameters which may be identified are : element area, mass...

  • The geochemical partitioning and bioavailability of trace metals in marine sediments

    Creator:
    Oakley, Stewart M.
    Abstract:
    Trace metals in the aquatic environment are generally concentrated on the surface of solid geochemical phases which eventually become incorporated into estuarine and marine sediments. The mechanism of trace metal concentration is believed to be adsorption with various geochemical phases such as hydrous metal oxides, clays, and organic matter. Metals...

  • The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

    Creator:
    Martin, Duane Collins
    Abstract:
    A study of the effect of mixing on the oxygen uptake rate of estuarine bottom deposits is presented. The method of study involved the mixing of samples of bottom deposits with the overlying water to result in concentrations of suspended matter in the same order as observed in the estuary....

  • Use of benthic sediments as indicators of marina flushing

    Creator:
    Noble, Scott Morgan
    Abstract:
    This report presents the findings of a sediment analysis program formulated to determine the flushing potential of various shaped small boat marina basins. Chemical tests regarding volatile solids, Kjeldahl nitrogen, grease and oil, and sulfides were performed with the results compared to established sediment quality criteria. These results were used...

  • Applications of Marine Radar Wave Observation Systems

    Creator:
    Meskill, Shay J.
    Abstract:
    This project utilized both shore-based and shipboard commercial marine radar technology to collect wave statistics. In the first application a shore-based system was installed at Yaquina Bay in Newport, Oregon in order to collect real-time wave information. This information was collected under the auspices of the Northwest Association of Networked...

  • The Application of Machine Learning Techniques on Marine Science Models

    Creator:
    Ellenson, Ashley
    Abstract:
    A variety of stakeholders require information about marine systems. In the open ocean, pilots of marine vessels require knowledge about environmental conditions for safe passage and route planning. On the coastline, communities rely on information about nearshore dynamics to increase safety from coastal hazards such as nearshore pollutants, coastal erosion,...

  • Depth estimation and frontal imaging via X-band marine radar

    Creator:
    Honegger, David Andrew
    Abstract:
    This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...
