  Surface waves on both superfluid 3He and 4He were examined with the premise,
that these inviscid media would represent ideal realizations for this fluid
dynamics problem. The work on 3He is one of the first of its kind, but on 4He
it was possible to produce much more complete set of data for meaningful
comparison with theoretical models. Most measurements were performed at the
zero temperature limit, meaning T < 100 mK for 4He and T ~ 100 {\mu}K for 3He.
Dozens of surface wave resonances, including up to 11 overtones, were observed
and monitored as the liquid depth in the cell was varied. Despite of the wealth
of data, perfect agreement with the constructed theoretical models could not be
achieved.
