  • The influence of early diagenesis on trace element and molybdenum isotope geochemistry

    Creator:
    Poulson, Rebecca L.
    Abstract:
    This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter...

  • Glacial to holocene watermass and continental weathering reconstructions from the Southeast Pacific

    Creator:
    Muratli, Jesse M.
    Abstract:
    Sediments of the central Chile margin record changes in ocean circulation and continental erosion associated with large–scale climate change. Here Antarctic– influenced Southern Ocean currents flow equatorward, forming a link between the high– and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important conduit that ventilates South...

  • Influence of a Sedimentary Source of Nd on Deep Ocean εNd Distributions

    Creator:
    Abbott, April N.
    Abstract:
    Ocean circulation is an important component in Earth's climate system. Predicting future climate and circulation changes requires an improved understanding of the past relationship between climate and ocean currents. The neodymium isotope composition (εNd) of water masses is frequently used as a quasi-conservative tracer to reconstruct ocean circulation. The current...
