Giant rogue waves that rise from the deep can do massive damage to ships and oil platforms. Not only are they often twice as tall as surrounding waves, but they seem to strike without warning. What if these sea monsters drop some hints before they appear? To find out how random rogue waves actually are, Gunter Steinmeyer and his colleagues at the Max Born Institute in Berlin, Germany, examined wave heights measured over time at the Draupner oil platform off the coast of Norway, where a rogue wave struck in 1995. They sliced the data into segments of varying length, looking for those with nearly identical features. Then they randomly shuffled the data and again looked for such repeated events.
