  • The leading edge of a tropical instability wave : interpretation as a gravity current

    Creator:
    McHugh, Elizabeth Helen
    Abstract:
    A sharp temperature front, oriented along the south-west corner of the leading edge of a Tropical Instability Wave (TIW) warm trough, was encountered at 0°N, 140°W on November 2, 2008 and detected by a 0.45°C increase in SST that occurred over 7 s. The distinct SST signal was observed at...

  • Nonlinear internal waves on the continental shelf

    Creator:
    Shroyer, Emily L.
    Abstract:
    The properties and evolution of nonlinear internal waves (NLIWs) depend upon the background conditions within which waves form, propagate, and dissipate. As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged...

  • Xpod and GusT Processing Manual

    Creator:
    Warner, Sally J.
    Abstract:
    This manual gives step-by-step instructions for processing raw data measured by chipod and GusT turbulence sensors. These instruments are designed and manufactured by the Ocean Mixing Group in Oregon State University's College of Earth, Ocean, and Atmospheric Sciences.

  • Evolution of Turbulence, Heat Content, and Freshwater Lenses in the Diurnal Warm Layer

    Creator:
    Moulin, Aurélie J.
    Abstract:
    Thorough understanding of the mechanisms controlling the temperature structure in the surface mixed layer of the ocean and, in particular, accurate values of sea surface temperature are critical for properly parameterizing air-sea heat exchange and quantifying the amount of heat redistributed below the surface. It is however difficult to obtain...

  • A Permanent-Magnet Linear Generator Wave Energy Converter for Low Power Ocean Sensors

    Creator:
    Miles, Lillian F.
    Abstract:
    Renewable energy sources are becoming increasingly important due to their low environmental impact and limitless nature. This thesis explores the design of a 250 mW permanent magnet linear generator wave energy converter to power ocean sensors. While many wave energy converters exist, this is a unique application because the wave...

  • How we live with words

    Creator:
    Rhoten, Karalee N.
    Abstract:
    The words we use to define our lives are often determined by the way we render any given moment. Every instance of writing is a moment of remembering, and a non-fiction essay gives the author free rein to unravel an instance, paint a portrait of what time has already come...

  • Dynamics of the Columbia River tidal plume

    Creator:
    Kilcher, Levi F.
    Abstract:
    This dissertation investigates the dynamics of the tidally modulated outflow from the Columbia River mouth using high resolution measurements of velocity, density and turbulent microstructure. At high tide, flow through the river mouth reverses from flood (onshore) to ebb (offshore). During ebb, buoyant fluid issues from the river mouth and...

  • Shear and convective turbulence in a model of thermohaline intrusions

    Creator:
    Mueller, Rachael
    Abstract:
    Thermohaline interleaving is an important mechanism for laterally fluxing salt, heat, and nutrients between oceanic water masses. Interleaving is driven by a release of potential energy resulting from the vastly differing diffusivities of heat and salt in seawater. The flows are composed of stacked intrusions that flux more buoyant and...

  • Internal hydraulic flows on the continental shelf: High drag states over a small bank

    Creator:
    Nash, Jonathan D. and Moum, James N.
    Abstract:
    Observations of currents, hydrography, and turbulence provide unambiguous evidence for hydraulic control of flow over an isolated three-dimensional topographic feature on Oregon’s continental shelf. The flow becomes critical at the crest of the bank, forming a strong supercritical downslope flow in the lower layer. Farther downstream, internal hydraulic jumps form...

  • Microstructure estimates of turbulent salinity flux and the dissipation spectrum of salinity

    Creator:
    Nash, Jonathan D. and Moum, James N.
    Abstract:
    Direct determination of the irreversible turbulent flux of salinity in the ocean has not been possible because of the complexity of measuring salinity on the smallest scales over which it mixes. Presented is an analysis of turbulent salinity microstructure from measurements using a combined fast-conductivity/temperature probe on a slowly falling...
