  • Dispersion of the Columbia River plume based on radioactivity measurements

    Creator:
    Frederick, Lawrence Churchill
    Abstract:
    An investigation has been made of several physical parameters of the effluent plume of the Columbia River as it enters the Pacific Ocean. Radioactive material in trace amounts enters the Columbia River from the Hanford nuclear reactors at Richland, Washington. One of these nuclides, chromium -51, has been used to...

  • Radioecology of ⁶⁵Zn in an arm of the Columbia River Estuary

    Creator:
    Renfro, William Charles
    Abstract:
    Levels of ⁶⁵Zn in water, sediments, plants, and animals in Alder Slough, a small ecosystem in the Columbia River Estuary, were determined periodically during a one year period. Concentrations of total Zn in organisms were also measured to permit computation of specific activities (μCi⁶⁵Zn/g total Zn). Temporal fluctuations in the...

  • The Columbia River as a source of marine light scattering particles

    Creator:
    Pak, Hasong
    Abstract:
    The Columbia River plume region was investigated during the period of 20 June to 3 July, 1968 by light scattering measurements and standard hydrographic station observations. The Columbia River plume was traced by the light scattering particles of the plume water. The light scattering particles are estimated to be contained...

  • Physical parameters as tracers of Columbia River water

    Creator:
    Evans, Richard H.
    Abstract:
    Hydrographic and bathythermograph data taken off the Oregon coast during a two week period in August of 1969 were analyzed to determine if heat content and mixed layer depth may be used as indicators of Columbia River plume water. Heat content was found to be a poor indicator of plume...
