  We look for classical traces of the Unruh effect in gravity waves. For this
purpose, we start considering a white noise state of gravity waves on the
surface of a water basin and calculate the two- and four-point functions of the
Fourier transform of the surface-height field with respect to accelerated
observers. The influence of the basin boundaries and possible deviations from
Gaussianity in the white noise state are considered in order to approximate
conditions attainable in the laboratory. Eventually, we make the basin
infinitely large in order to make contact between our classical results and
quantum ones derived in free space. We hope that our results help to strengthen
the bridge between the Unruh effect and this classical analog.
