    <subfield code="a">&lt;p&gt;Particle Tracking Velocimetry was used to study turbulence beneath short&lt;br /&gt;
wind-induced water-waves at the circular wind-wave facility of the Institute&lt;br /&gt;
for Environmental Physics. Recording image sequences at up to 200 Hz allow&lt;br /&gt;
an extensive study of the flow field. An automatic tracking algorithm&lt;br /&gt;
was developed for the evaluation of the trajectories. Monte Carlo simulations&lt;br /&gt;
show that Lagrangian flow field measurements offer an ideal approach&lt;br /&gt;
to the study of drift profiles (mass transport) in the turbulent wave region.&lt;br /&gt;
Also bulk velocity and surface velocities can be calculated. A measure for&lt;br /&gt;
the turbulence was gained by the calculation of the friction velocity profile&lt;br /&gt;
by correlating horizontal and vertical velocity components (eddy correlation&lt;br /&gt;
