“Rogue waves are generated by wind, so they are just a rare occurrence of wind generated waves. Although both are known for being large waves, the way they come about is completely different. One common misconception Gemmrich wanted to emphasize is rogue waves are not to be mistaken for tsunamis. If it is high enough that it can cause some damage to the vessel, the operator has no time to change course or react to it.” Gemmrich added. “They are unexpected, so the vessel operator has little warning. Such waves can pose a significant threat to marine operations as well as the public due to their immense power and lack of predictability, Beatty stressed. One thing is known for sure: Rogue waves are not afraid to rock the boat. That is the big science question,” Gemmrich noted. “Most observations are at a single buoy, a single location, and so the wave passes through, and we know at this moment it was this high, but we don’t know how long. The problem lies in how to continuously track rogue waves once identified by a sensor. The company produced a video simulation of the buoy around the time the rogue wave came through, showing the swell in comparison to the smaller surrounding waves. “We’re a real-time intelligence company, and we provide real-time updates on what is going on along the coastline, including wind, waves, and other data,” Beatty explained. The rogue wave in the study was measured via a MarineLabs buoy approximately 4.3 miles (7 kilometers) off of the coast of Ucluelet, British Columbia. Recording these “killer waves” is no easy feat The record-breaking rogue wave recorded in November 2020 measured at almost 58 feet (17.6 meters) in comparison to surrounding waves of around 20 feet (6 meters), blowing the original proportions out of the water. The first rogue wave recorded, known as “The Draupner Wave,” was measured in 1995 off the coast of Norway at 84 feet (25.6 meters) with surrounding waves of approximately 40 feet (12 meters), making the original rogue wave about twice the size of those around it. Thus, while a wave achieving a four-story height equivalent is impressive, its magnitude being three times that of its surrounding waves is what landed it in the record books. Overall size doesn’t matter, but the comparison in size to other waves does. In simplified terms, “A rogue wave is actually just a wave that is large compared to the surrounding wave field,” Gemmrich clarified. “Rogues, called ‘extreme storm waves’ by scientists, are those waves which are greater than twice the size of surrounding waves, are very unpredictable, and often come unexpectedly from directions other than prevailing wind and waves,” the National Oceanic and Atmospheric Administration (NOAA) explained. In the past few decades, what was once known as marine folklore has now been accepted as real by scientists. “They look like a large four-story lump sticking out of the water with a large peak and big troughs before it,” Scott Beatty, CEO of MarineLabs, the company operating the buoy which measured the wave, told CNN.
