  The last decade has seen a significant increase in the number of studies
devoted to wave turbulence. Many deal with water waves, as modeling of ocean
waves has historically motivated the development of weak turbulence theory,
which adresses the dynamics of a random ensemble of weakly nonlinear waves in
interaction. Recent advances in experiments have shown that this theoretical
picture is too idealized to capture experimental observations. While gravity
dominates much of the oceanic spectrum, waves observed in the laboratory are in
fact gravity-capillary waves, due to the restricted size of wave basins. This
richer physics induces many interleaved physical effects far beyond the
theoretical framework, notably in the vicinity of the gravity-capillary
crossover. These include dissipation, finite-system size effects, and finite
nonlinearity effects. Simultaneous space-and-time resolved techniques, now
available, open the way for a much more advanced analysis of these effects.
