Hello, I made this realistic animated ocean in blender cycles with combination of many tutorials I've seen to have the best result and here it is... I hope you enjoy this scene. You can add whatever you want and use it for your films. And tell me what you think about it. I've add a sky, a focus empty and I removed the sun to have a best render, now it's so much better ! april 2016. V2 Thanks!
