...among other bloody military engagements - was just a blur on a map that seemed impossibly exotic and faraway. "Strange to think that I've become the World War II guy," Hanks laughs. "All my friends had dads who were on the U.S.S. Nimitz or U.S.S. Enterprise or U.S.S. Coral Sea. They lived in naval housing, and everybody who was like a primary caregiver to me talked about the war. But when it came to understanding the history, I nodded...
Until recently, however, marine scientists dismissed the idea of rogue waves as little more than a sailors' fantasy, with reason - there was little evidence to back it up. But in 1995, an oil rig in the North Sea recorded an 84-ft.-high (25.6 m) wave that appeared out of nowhere, and in 2000, a British oceanographic vessel recorded a 95-ft.-high (29 m) wave off the coast of Scotland. In 2004, scientists from the European Space Agency (ESA), as part of the MaxWave project, used satellite data to show that freak waves higher than 10 stories were rare...
Scientists still don't know exactly how rogue waves occur, nor do they know how to predict them. Open ocean waves, possibly including rogue waves, form when wind produces distortion over the surface of the sea - the stronger the wind, the higher the wave, which is why hurricanes can create such destructive walls of water. Tsunamis, on the other hand, like the one produced by the 8.8-magnitude earthquake in coastal Chile on Feb. 27, don't create rogue waves; tsunamis barely make a ripple on the open ocean and gather in size only when they reach shallow land near...
...that rogue waves might be a lot more common than scientists had believed and could explain why so many large ships - as many as two a week - sink even in the absence of bad weather. One day we might even be able to predict when these earthquakes of the sea occur - sparing future cruisegoers the trauma suffered by those on the Louis Majesty...
...side of the border, China frequently gets the blame for water shortages downstream. Indeed, Vietnam's neighbor has been on an aggressive campaign to damn the Mekong River, which begins on the Tibetan plateau and travels through five other countries before it empties into the South China Sea. According to the Mekong River Commission, a regional advisory agency, China has built or is planning to build eight dams along the Mekong. But while dams raise huge concerns about interfering with sediment flow and fish migration, they can also have a positive impact, says Jeremy Bird, the commission's chief executive...
