Highly nonlinear wave phenomena are ubiquitous in the ocean, but the understanding of their generation and evolution is far from complete. In this talk, described are two examples of such phenomena: giant internal solitary waves in the interior of the ocean and rogue waves on the ocean surface. After describing their unique physical characteristics along with field observations, our recent attempts to develop new mathematical models for the time evolution of these highly nonlinear waves will be introduced. Validation of the models and their numerical solutions with laboratory experiments will be also presented and some of remaining challenges will be discussed.
