    "description": "<p>Particle Tracking Velocimetry was used to study turbulence beneath short<br />\nwind-induced water-waves at the circular wind-wave facility of the Institute<br />\nfor Environmental Physics. Recording image sequences at up to 200 Hz allow<br />\nan extensive study of the flow field. An automatic tracking algorithm<br />\nwas developed for the evaluation of the trajectories. Monte Carlo simulations<br />\nshow that Lagrangian flow field measurements offer an ideal approach<br />\nto the study of drift profiles (mass transport) in the turbulent wave region.<br />\nAlso bulk velocity and surface velocities can be calculated. A measure for<br />\nthe turbulence was gained by the calculation of the friction velocity profile<br />\nby correlating horizontal and vertical velocity components (eddy correlation<br />\ntechnique).</p>",
