"Rogue waves that rise as high as 10-story buildings and can sink large ships are far more common than previously thought, imagery from European Space Agency (ESA) satellites has shown."

This is a little disconcerting. I've spent many a day on the ocean and have never seen a wave like this (even in hurricane sorties, thank goodness). If you read the press release from the ESA you can learn a little more about this. Susanne Lehner from the University of Miami is working this so we'll look out for more from her.
