There are many types of ocean wave: presumably you mean those in deep water driven by wind on the sea surface. Although those waves move constantly forward, the water itself moves up, round, down and back in an orbital motion that gets smaller the deeper you go. More precisely, the diameter and velocity of the orbit both fall off exponentially with depth. As a rule of thumb, the depth of the wave is about the same as the distance between peaks.
