  It is noted that the results of recent experiments on the enhancement of
turbulent kinetic energy (TKE) dissipation below surface waves can be stated as
follows. TKE dissipation is enhanced by a factor $15 H_{ws}/z$ at depths $0.5
H_{ws} < z < 20 H_{ws}$ with respect to the wall-layer result $\epsilon =
u_{*w}^3/\kappa z$, where $u_{*w}$ is the friction velocity in water and
$H_{ws}$ is the significant wind-sea wave height. For open ocean conditions,
this reduces in most cases to an enhancement factor $10^6 u_{*w}^2/gz \approx
U_{10}^2/gz$.
