    Description:
      Abstract:
        These data tables are a result of a seabed ripple morphology
        and surficial sediment size field study in 2004 and
        are an integral part of the report whose aim
        is to present methods employed to extract data and
        the resulting measured ripple characteristics
        (i.e., ripple height, wavelength, and orientation) and
        seabed grain sizes near Fort Walton Beach, Florida.
      Purpose:
        Sediment transport in the coastal region is a complex process
        involving interactions between flow dynamics, sediments, and
        bedforms.  Sediment type and bed geometry directly influence
        entrainment of sediments into suspension, and at sites where
        ripples occur (sand formations on the order of several cm high
        and less than two meter long wavelengths), the understanding
        of ripple dynamics is an essential component in improving
        sediment transport models.  To gain a better understanding
        and ability to predict sediment transport, a field study
        was undertaken to investigate morphology, orientation, and
        dynamics of ripples on the seafloor.

  Data_Quality_Information:
    Logical_Consistency_Report: Ripple wavelength and height measurements are direct interpretations from sonar data corrected for tilt and rotation where necessary.  Ripple heights are estimates based on best fit sinusoids to measured profile data.  Grain sizes represent direct point measurements of surficial sediments.
    Completeness_Report: All avaialble data were analyzed; in cases where multiple data were available for a given site and parameter, optimal results based on statistcal analyses are reported.
