  • Factors that influence sulfide production in an estuarine environment

    Creator:
    Peterson, Paul Edward
    Abstract:
    Core samples from five sites in the Yaquina and Coos Estuary were assayed for vertical distribution of total sulfides, percent volatile solids, redox potential, particle size, total aerobic and sulfate reducing bacteria. Higher total sulfide levels were found at sites having more than four percent volatile solids, redox potential below...

  • Some aspects of the sulfur cycle in tidal flat areas, and their impact on estuarine water quality

    Creator:
    Ramm, Alan Edmund
    Abstract:
    A conceptual model of the tidal flat system, emphasizing the sulfur cycle was presented. Measurements were made of the vertical distribution within tidal flat deposits of total aerobic and sulfate reducing bacteria, total sulfides, redox potential, volatile solids, and particle size. Variations in dissolved oxygen and free sulfides in the...
