  • Patterns in coastal marsh vegetation of the Juneau area, Alaska

    Creator:
    Stone, Catherine S.
    Abstract:
    A vegetation study was made of four coastal marshes near Juneau, Alaska. Results confirmed earlier studies' findings in southeast Alaska that communities or assemblages of species can be identified but from marsh to marsh these assemblages appear to have no consistent relationship to each other or to environmental "factors" such...

  • Salt marsh reestablishment following dike breaching in the Salmon River estuary, Oregon

    Creator:
    Mitchell, Diane Lynne
    Abstract:
    A 22 ha, 1S yeas old, diked permanent pasture in the Salmon River estuary in Lincoln County, Oregon, was chosen for a study to determine the potential for natural salt marsh restoration with dike breaching. Two undiked fragments of relatively undisturbed salt marsh, one at each end of the study...

  • Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

    Creator:
    Buffington, Kevin J.
    Abstract:
    Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

  • Development of predictive mapping techniques for soil survey and salinity mapping

    Creator:
    Elnaggar, Abdelhamid A.
    Abstract:
    Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...
