  • Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

    Creator:
    O'Neill, Larry W.
    Abstract:
    Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

  • Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

    Creator:
    Thum, Nicolai
    Abstract:
    This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

  • A satellite-derived climatology of global ocean winds

    Creator:
    Risien, Craig Miller
    Abstract:
    A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...

  • Studies on the spatial variability of phytoplankton physiology and biomass in the Oregon upwelling system

    Creator:
    Sanders, Rachel B.
    Abstract:
    The Oregon upwelling system is a region of high biomass and primary productivity as well as strong mesoscale variability. In order to examine the interaction of physical forcing and ecosystem dynamics, four 3-week sampling cruises were conducted in the Oregon upwelling system as part of the Northeast Pacific Global Ocean...

  • An X-radiographic study of the October 2000 Po River flood deposit, Italy

    Creator:
    Hunt, Louise
    Abstract:
    During October 2000 the Po River, Italy's largest river, experienced a historically significant flood, producing a deposit on the adjacent prodelta. In December 2000 an event-response study of the deposit was conducted, and during the ensuing 16 months three additional sampling cruises were conducted to study the subsequent evolution of...

  • Numerical and assimilative studies of the equatorial Pacific cold tongue

    Creator:
    Perez, Renellys Christine
    Abstract:
    Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during August 1999 to July 2004. The numerical model was first applied to test two hypotheses (asymmetric background currents and...

  • The cross-equatorial structure of tropical instability waves in sea surface height

    Creator:
    Lyman, John M.
    Abstract:
    A linearized model with two vertical modes has been developed to understand observed characteristics of monthly variability in the Equatorial Pacific from TOPEX/POSEIDON measurements of Sea Surface Height (SSH). The 2-mode model is obtained from an equatorial beta plane model that has been linearized about a geostrophically balanced mean flow...

  • The South Atlantic Ocean response to local and remote forcings

    Creator:
    Fetter Filho, Antonio F. H.
    Abstract:
    The local and remote sources of variability of the South Atlantic Ocean are investigated using a set of numerical experiments and satellite data. A global, eddy-permitting, numerical simulation is analyzed to investigate the dynamical links between the Antarctic Circumpolar Current (ACC) and the Malvinas Current (MC). The model results indicate...

  • SeaSoar observations during the Coastal Ocean Advances in Shelf Transport (COAST) mesoscale survey II : R/V Wecoma cruise from 6 to 26 August 2001

    Creator:
    O'Malley, Robert T., Barth, John A., and Erofeev, Anatoli Y.
    Abstract:
    As part of the Coastal Ocean Processes (CoOP) project Coastal Ocean Advances in Shelf Transport (COAST), this was the second of two cruises in 2001 to study cross-shelf transport processes in a wind-driven coastal ocean. The project includes field experiments off the Oregon coast and coordinated ocean circulation/ecosystem and atmospheric...
