  • Kinematics and Dynamics of a Model Eastern-boundary Poleward Undercurrent

    Creator:
    Duran, Rodrigo
    Abstract:
    A carefully calibrated primitive-equation model from 41°N to 48°N is used to study the poleward undercurrent off the US west coast. Chapter 2 describes poleward flow over the slope from Eulerian and Lagrangian perspectives. The model is robust, in the sense of several characteristics being qualitatively consistent with observational and...

  • The effect of river discharge and wind forcing on the Oregon coastal ocean during fall and winter

    Creator:
    Mazzini, Piero Luigi Fernandes
    Abstract:
    Freshwater provided from river discharge influences the dynamics and circulation of most continental shelves around the world. It has profound effects on the transport and fate of materials and substances originated from rivers and estuaries, as well as on the ocean biogeochemistry and marine ecosystems. The effect of buoyancy forcing...

  • The Ocean Circulation and Carbon Cycle during the Last Glacial Maximum

    Creator:
    Muglia, Juan
    Abstract:
    During the Last Glacial Maximum (LGM, ∼ 21 ky before present) the atmospheric CO2 concentration was about 100 ppm lower than its pre-industrial (PI)value. The missing carbon from the atmosphere must have been stored in thedeep ocean during this period, but the mechanisms driving such re-distribution ofthe carbon cycle are...

  • Coastal ocean variability inferred from high resolution models : two case studies

    Creator:
    Mauch, Matthew L.
    Abstract:
    In this thesis, high resolution ocean models are used to evaluate and forecast coastal ocean variability in two different applications. In the first study, the 2-km resolution ocean circulation model for the Eastern Bering Sea is utilized to understand whether slope-interior exchange along the path of the Aleutian North Slope...

  • Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

    Creator:
    Mayorga Adame, Claudia Gabriela
    Abstract:
    A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

  • Intra-seasonal sea level variability along the west coast of India

    Creator:
    Dhage, Laxmikant
    Abstract:
    The importance of local versus distant forcing is studied for the wind driven intra- seasonal (30-120 day) sea level anomaly (SLA) variations along the west coast of India. Three locations on the continental slope are chosen to represent the west coast. Two more locations, one east of Sri-Lanka and another...

  • 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...

  • Turbulence in sheared, salt-fingering favorable environment

    Creator:
    Kimura, Satoshi
    Abstract:
    Instability and turbulence in sheared, salt-fingering favorable stratification are studied using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable stratification is gravitationally stable, because the unstable vertical gradient of salinity is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering instability can occur at the interface of these different water-masses....
