 Yeah, these are waves that are at least twice the size of other waves in the area, but they can be much, much larger, like dozens of feet high, swallow up your boat larger. And they're very unpredictable. So this can really be a threat to ships or exposed structures like lighthouses. In work this week, researchers have developed a computer system that used machine learning plus tons of measurements from ocean buoys to try and predict when these waves are going to come up.
