[Abstract]

Rogue waves are extreme wave events that are known to occur in offshore as well as as in coastal areas. One possible explanation for their formation in deep-water is the modulation instability. This latter instability can be described through exact deterministic breather models that have been shown to be very useful in controlling extreme waves in laboratory environments and thus, becoming very relevant for ocean engineering applications. Experiments on hydrodynamic breathers and other fundamental nonlinear localisations on the water surface will be presented. A particular emphasis will be given to nonlinear wave dynamics in the transition from deep- to shallow-water regime. Moreover, recent results on the evaluation of ocean current data sets, provided by NASA, will be shown.
