  • A mesoscale study of coastal currents and upwelling off Peru

    Creator:
    Enfield, David B.
    Abstract:
    Moored instrument records, drogue displacements, and hydrographic observations are used in describing the coastal currents and upwelling off Peru. The data were obtained over the continental shelf near 15°S. during a two week study in late March and early April of 1969. First order statistics and graphical representations of current...

  • Vertical current measurement in the Oregon coastal upwelling region

    Creator:
    Deckard, Dennis E.
    Abstract:
    Direct measurements of vertical water motions were made in the Oregon coastal region during the 1972 summer upwelling season. The instruments used were the Webb-Voorhis vertical current meters which are freely drifting neutrally buoyant floats capable of sensing vertical motion. It was found that in the region studied, water tended...

  • The response of Oregon shelf waters to wind fluctuations : differences and the transition between winter and summer

    Creator:
    Sobey, Edwin J. C., 1948-
    Abstract:
    The physical characteristics of continental shelf waters off Oregon during late winter and spring of 1975 are described and compared with observations taken previously during summer. The currents in winter are barotropic in the monthly means while in summer the currents are baroclinic. Alongshore current fluctuations on the time scale...

  • Equatorward jets and poleward undercurrents along the eastern boundary of the mid-latitude north Pacific

    Creator:
    Pierce, Stephen D.
    Abstract:
    We sharpen our view of an eastern boundary current region during the upwelling season through the analysis of several data sets. We focus on the mesoscale flow field off of northern California, observed during the Coastal Transition Zone (CTZ) experiment of 1988. First, we estimate tidal currents in the region...

  • A description of hydrography, winds, and currents during the upwelling season near Newport, Oregon

    Creator:
    Pillsbury, R. Dale
    Abstract:
    Several series of measurements of the hydrography, currents, and winds during the past ten years are used as a basis for an overview of the physical oceanography and meteorology during the upwelling season near Newport, Oregon. Data are described using elementary statistics, progressive vector diagrams, coordinate system independent spectra, and...

  • Low frequency variations in the sea level and currents over the Oregon continental shelf

    Creator:
    Cutchin, David L.
    Abstract:
    Sea level and current observations made over the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cpd. In a narrow band around 0.22 cpd the current-sea level relationship is consistent with the predicted values for the first mode of Robinson's continental shelf waves....
