  • Computer analysis of the surface current field off Oregon based on drift bottle data

    Creator:
    Lung, Hu Ernest
    Abstract:
    The fall-winter surface current field off Oregon was determined by analysis of ten years of drift bottle data. Computer programs were developed for generating bottle tracks on a numerical grid, for interpolating bottle velocity components to fill void grid points and for smoothing irregularities in the velocity fields. Charts are...

  • Plankton and nutrient ecology of the Columbia River estuary

    Creator:
    Haertel, Lois Steben
    Abstract:
    Monthly samples of nutrients, phytoplankton and zooplankton were taken in the Columbia River estuary over a period of 16 months in order to determine distribution with season and salinity, and interrelationships between plankton and nutrients. Nitrate and phosphate levels in the river water entering the estuary are high in the...

  • Magnetic and gravity interpretation of Yaloc-69 data from the Cocos plate area

    Creator:
    Lu, Richard Shih-Ming
    Abstract:
    Magnetic, gravity and bathymetry data were collected on an extended cruise of the R/V Yaquina in 1969. The last set of data was obtained from those track lines leaving the Panama Basin. The area covered is mainly the Cocos plate (Molnar and Sykes, 1969). The data is analyzed and compared...

  • Marine geology of the continental margin off southern Oregon

    Creator:
    Spigai, Joseph John
    Abstract:
    The continental margin off southern Oregon, which includes the shelf and slope from Cape Blanco to the Oregon-California border, exhibits a distinctive marginal-plateau structural pattern which divides the margin into the continental shelf, the upper continental slope and its associated benches, and the lower continental slope. Lutum transport and deposition...

  • Distribution of Euphausiacea and Copepoda off Oregon in relation to oceanographic conditions

    Creator:
    Hebard, James Frank
    Abstract:
    Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...

  • Precise north-south oceanographic transect in the Pacific Ocean

    Creator:
    Cabrera-Muro, Homero
    Abstract:
    The Geochemical Ocean Sections Study (GEOSECS) program has carried out an intensive study of physical and chemical parameters in the Pacific and Atlantic Ocean. As a result, an enormous collection of high quality data has been amassed for these two oceans. To analyze the Pacific data, fourteen stations extending from...

  • Application of transport-reaction modeling to constrain biogeochemical processes in marine sediments

    Creator:
    Hong, Wei-Li
    Abstract:
    Quantifying the mass transport through marine sediments, and the geochemical response to such flow with numerical models has become a common and powerful approach for geochemical data interpretation. In this dissertation, I developed and applied transport-reaction models to unravel complex and interdependent reactions involving carbon, sulfur and silica transformations in...

  • Diffuse deformation patterns along the North American plate boundary zone, offshore western United States

    Creator:
    Chaytor, Jason D.
    Abstract:
    Plate boundaries are commonly regions of complex, diffuse deformation with the motion across the boundary accommodated by numerous structural systems, rather than being narrow, discrete zones of deformation. One such boundary occurs where the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates along the west...

  • Mathematical approaches to the physics of mesoscale oceanography

    Creator:
    Early, Jeffrey J.
    Abstract:
    The long-term evolution of Gaussian eddies is studied in an equivalent barotropic model using both linear and nonlinear quasi-geostrophic theory in an attempt to understand westward propagating satellite altimetry tracked mesoscale eddies. By examining both individual eddies and a large basin seeded with eddies, it is shown that long term...

  • The effect of the land breeze on the mesoscale wind field off the Oregon coast

    Creator:
    Poole, Stephen Lynn
    Abstract:
    Two land breeze events occurred off the Oregon coast on the nights of April 19th and 20th, 1973. An array of four moored toroid buoys and one land station recorded the effect of the land breeze event on the surface mesoscale wind and temperature fields. The land breezes may have...
