  We present laboratory experiments of surface wave turbulence excited by
paddles in the deep water regime. The free surface is seeded with buoyant
particles that are advected and dispersed by the flow. Positions and velocities
of the floaters are measured using particle tracking velocimetry. We study the
statistics of velocity and acceleration of the particles, mean vertical
displacements, single-particle horizontal dispersion, and the phenomenon of
preferential concentration. Using a simple model together with the experimental
data, we show that the time evolution of the particles has three characteristic
processes that dominate the dynamics at different times: drag by surface waves
at early times, trapping by horizontal eddies at intermediate times, and
advection by a large-scale mean circulation at late times.
