Apparently, there’s a big-budget remake of the 70’s disaster movie The Poseidon Adventure being made, and the first trailer just hit the ‘net.
As I was watching the trailer, a shot of the huge wave bearing down on the ocean liner made me wonder about just how likely such an event really was. To my (admittedly limited) knowledge, waves such as that are generally associated with tsunamis, where waves that might be unnoticeable on the ocean grow to incredible height as they progress into shallower water near shore. Large waves away from shore are generally associated with storms or hurricanes. So, to see a wave large enough to capsize a modern ocean liner in the open sea on an otherwise clear night seemed to be straining, if not outright breaking credibility.
In my head, then, I decided that part of the remake should be the question of where such a wave would come from and what could generate it. In my version of the movie, the survivors of the capsized cruise ship would make it to the surface, find a life raft or some other craft, and make it in to shore…only to discover that the wave had been generated by a huge meteor or asteroid crashing into the ocean not far from their ship, and by the time they’d escaped the ship and made it to land, huge tsunamis had wiped out entire coastlines across the world, practically destroying the world as they’d known it. Kind of a modern-day Planet of the Apes ending, only without the sci-fi time travel element.
What really surprised me when starting to write this post, then, was noting these two passages on the IMDB’s trivia page for The Poseidon Adventure:
Paul Gallico was inspired to write his novel by a voyage he made on the Queen Mary. When he was having breakfast in the dining room, the liner was hit by a large wave, sending people and furniture crashing to the other side of the vessel. He was further inspired by a true incident which occurred aboard the Queen Mary during World War II. Packed with American troops bound for Europe, the ship was struck by a gargantuan freak wave in the North Atlantic. It was calculated that if the ship had rolled another five inches, she would have capsized like the Poseidon.
Such mid-ocean “rogue waves” were previously thought to occur only once every ten thousand years. A 2004 study of satellite radar images showed they can happen as often as hundreds of times every decade.
Whoa. Such waves are real? Apparently so!
Rogue waves are freakishly large waves, much bigger than the surrounding swell. They seem to rear up out of nowhere, sometimes out of a fairly calm sea, and disappear just as quickly. Mariners have recounted tales of such waves for centuries, but until recently oceanographers discounted them, along with sightings of sea monsters and mermaids. Naval architects, however, have analyzed the wrecks of ships sunk in recent decades, and have found that a large proportion of them have damage consistent with an encounter with a rogue wave, which can reach heights of a hundred feet. Even supertankers have been sunk by these monster waves. Now the evidence is too great to ignore, and physicists are trying to understand how rogue waves are generated. The issue is important not only for our understanding of the ocean, but also because rogue waves seem to be responsible for the loss of many lives at sea.
Hot damn that’s cool. Freaky and scary, but really cool. Guess I should be giving the scriptwriters a tad more credit than I had been!
