Turbulence in the Shallow Nearshore Environment During SANDYDUCK '97
Abstract
An array of five acoustic Doppler velocimeters (ADV), which produce high quality measurements of the three-dimensional velocity vector in a sample volume with a scale of one centimeter, was deployed from late August through late November of 1997, at a water depth of approximately 4.5 m off Duck, North Carolina. The sensors were deployed near the sea floor but above the centimeters-thick wave boundary layer, and the sampling scheme was designed to resolve turbulence statistics averaged over tens of minutes, much longer than typical wave periods but shorter than time scales associated with variability of energetic wind-driven and wave-driven along shore flows. The purpose of this report is to document the instrumentation and deployment of the ADV array, to present an overview of the data, to describe the data processing and preliminary analysis, and to document the formats of the data archives.
