<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.
</abstract>
<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.

<logic>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.</logic>
<complete>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.</complete>
