Massive waves up to 100 feet in height -- once thought to be extremely rare -- actually roam the oceans quite frequently and could threaten to overturn ships and oil rigs, a European Commission study has found.
The study, announced last week and conducted on radar images gathered by two European Space Agency satellites during a three-week period in 2001, revealed that no fewer than 10 of the so-called rogue waves rose from various oceans around the world in that time. Not too long ago, scientists had believed that such waves formed just once every 10,000 years, according to the space agency.
The findings could lead to the prevention of many wave-related accidents in the future, said Wolfgang Rosenthal, lead researcher for
MaxWave, the European Commission-funded group responsible for the study.
Preventing wave-related accidents is both a financial and safety concern for the maritime industry. Most large ships and oil rigs are designed to withstand waves up to 50 feet. However, in 1995, an instrument onboard the Draupner oil rig in the North Sea recorded an 85-foot wave.
In 2001, two cruise ships in the South Atlantic -- the Bremen and the Caledonian Star -- reported that their bridge windows were smashed by 100-foot rogue waves.
MaxWave researchers suspect that rogue waves also played a role in the sinking of some of the 200 large supertankers and container ships that have gone down in bad weather over the past two decades.
Unfortunately for those in harm's way, there is still much more research to be done before a solution can be proposed. For instance, no one yet seems to know how the waves are formed in the first place.
"We don't know what's going on out there," said Paul Liu, an oceanographer and rogue-wave researcher with the National Oceanic and Atmospheric Administration. "There are some theories, but I don't think those theories can ever translate into the real ocean environment."
Indeed, while rogue waves have been found where currents meet, they have also appeared far away, leading researchers to believe that wind and other weather-related phenomena may also contribute to the waves' size.
A new project, dubbed
WaveAtlas, is now attempting to shed light on the mystery by creating a catalog of waves and related accidents that can be examined for correlations. The project group is expected to publish its findings in early 2005.
"I think there are a lot of rogue waves out there," he said. "It's like if a tree falls in the forest and no one is around to hear it. What happens if a wave appears in the ocean and no one can record it?"
If a wave appears in the ocean and no surfer is there to ride it......or
If a wave actually managed to appear at San Onofre, and no one was sober enough to ride it, did it really exist?
