Experts say France, Britain, Japan and perhaps the Soviet Union could also reach the sub. "Down to 20,000 ft., nothing's sacred anymore," says Frank Busby, an expert in deep-sea operations. "You can't put these ((vessels)) down there and call them a memorial anymore because we can reach anything." But reaching the site may be the easy part. At those depths, pressures are 4 tons p.s.i., and deep-sea submersibles are unsuited for raising large objects. Even if the sub's hull is crushed and the missiles are lying in the open on the ocean floor...
Between the two sections of the ship, the Woods Hole scientists found a large debris field littered with artifacts: a copper kettle polished by sand particles in the deep-sea currents; three of the ship's safes; a porcelain doll's head; a patent-leather shoe. Most of the ship's woodwork had been devoured by marine creatures. Amid the debris were at least four of the Titanic's huge boilers; an unbroken porcelain coffee cup rested on one of them. Says Ballard: "It must have fluttered down like a leaf and settled on the boiler, which had come crashing...
...well as a new pressure hull that enables it to operate as far down as 13,120 ft.). The stellar performance of the tiny sub during the second Titanic mission was only the latest in a long list of accomplishments. Among the more remarkable of Alvin's 1,716 deep-sea missions: locating and helping to recover (from a depth of 2,850 ft.) an H- bomb that fell into the Mediterranean after a B-52 bomber and a KC-135 tanker collided over Spain in 1966; discovering peculiar new life-forms, including tube worms 10 ft. long, while probing...
...seek the ill-fated ocean liner. From the moment the ship plunged to the bottom, people have dreamed of salvaging the vast riches said to be on board, but the great depths and stormy waters of the North Atlantic were thought to be insurmountable obstacles. Even the advent of deep-sea sonar equipment did not initially hold forth much promise for narrowing the search. Although the Titanic is believed to have ^ gone under at 41 degrees 46 min. north and 50 degrees 14 min. west, nobody has ever been sure of the exact coordinates; an error of only minutes...
...sturdy submersible that photographed the Titanic has a legendary forebear: it was named for the ship sailed by the Greek hero Jason as he searched for the Golden Fleece. And roam the Argo does, skimming just above the ocean floor like a giant sled. Designed to map deep-sea hills and gulleys, the craft can descend to depths of 20,000 ft. and remain underwater indefinitely. Essentially, it is a 16-ft.-long cage fashioned to protect a clutch of strobe lights, side-scanning sonar devices and an array of cameras from marine flotsam. The entire contraption is tied umbilically...
