  • Predicting the longshore-variable coastal response to hurricanes

    Creator:
    Stockdon, Hilary F.
    Abstract:
    The longshore variability of the coastal response to hurricanes may be examined within the framework of a storm-impact scaling model that compares spatially-variable beach morphology and fluid forcing. The relative elevations of dune height and storm-induced water levels are used to define three impact regimes (swash, collision, and overwash), within...

  • Paleo-oceanography of the subtropical southeastern Pacific during late Quaternary : a study of radiolaria, opal and quartz contents of deep-sea sediments

    Creator:
    Molina-Cruz, Adolfo
    Abstract:
    Micropaleontological data have been analyzed through mathematical and statistical procedures, in order to: (1) establish the distribution pattern of radiolarian assemblages in the surface sediments, (2) establish the relationship of these assemblages with oceanographic variables, (3) determine the faunal composition down-core with respect to the faunal surface pattern, and (4)...

  • The sediment response of a dissipative beach to variations in wave climate

    Creator:
    Haxel, Joseph H.
    Abstract:
    Using wave and wind data from nearby buoys and gauges, real time kinematic global positioning system (RTK-GPS) and light detection and ranging (lidar) topographic survey data, and a robust video record, we have quantified the Large Scale Coastal Behavior (LSCB) of a dissipative end member beach in the Pacific Northwest....

  • Sedimentation within the Cocos Gap, Panama Basin

    Creator:
    Dowding, Lynn Gretton
    Abstract:
    The Cocos Gap is a deeper portion, or saddle, of the Cocos Ridge and forms part of the western boundary of the Panama Basing It is probably typical of saddles within most submarine ridges, In order to determine the mechanisms controlling sediment dispersal, the nature and sources of the sediments...

  • Biogenic silica sedimentation in the central equatorial Pacific during the Cenozoic

    Creator:
    Leinen, Margaret, 1946-
    Abstract:
    A new technique for determining the amount of opal in deep-sea sediments of any age is described. Using a normative calculation, a portion of the analytical silica concentration of sediments is subtracted as non-biogenic in proportion to the concentration of aluminum in the sample. The ratio of SiO₂:Al₂O₃ used to...

  • Remote measurements of waves and currents over complex bathymetry

    Creator:
    Chickadel, Carmine C. (Carmine Christopher)
    Abstract:
    Waves are the primary input of energy in the nearshore region, and together with the currents forced through the transfer of momentum that occurs during the wave breaking process they are the principal mechanism for sediment transport in the nearshore. The basic physics of waves and currents are thought to...

  • Development of 2D models to estimate nearshore bathymetry and sediment transport

    Creator:
    Splinter, Kristen D.
    Abstract:
    We examine the interactions and feedbacks between bathymetry, waves, currents, and sediment transport. The first two pro jects focus on the use of remote sensing techniques to expand our knowledge of the nearshore. Due to the plethora of snap-shot data that is available from satellites and their distribution via Google...

  • Beach foreshore response to long-period waves in the swash-zone

    Creator:
    Howd, Peter A.
    Abstract:
    A field experiment designed to test the hypothesis that infragravity and lower frequency waves influence the patterns of erosion and deposition on the beach foreshore has been carried out. The data show coherent fluctuations in the foreshore sediment level which can be related to low frequency wave motions. The fluctuations...

  • Statistical distribution of swash maxima on natural beaches

    Creator:
    Holland, K. Todd
    Abstract:
    Beach response to overwash processes is a topic of significant importance. Two particular aspects of this topic were chosen for detailed analysis: the distribution of maximum wave runup elevations and the cross-beach celerity gradient of overwash bores on natural beaches. Data were collected using both traditional nearshore instrumentation and recently...
