  • Biotic alteration of oceanic basalt glass

    Creator:
    Drinnan, Megan R.
    Abstract:
    The subsurface microbial biosphere in the igneous oceanic crust has implications for global geochemical cycling, early life on Earth, and the search for life on Mars. Microscopic evidence of a subsurface microbial ecosystem includes biotic alteration textures associated with basaltic glass. The exact conditions in the basaltic layer that make...

  • 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...

  • Automated web-based analysis and visualization of spatiotemporal data

    Creator:
    Keon, Dylan B.
    Abstract:
    Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...
