...Titanic was damaged in these encounters. But in the process, the submersible collected the only artifact so far brought up from the great liner: a smudge of paint scraped from the smokestack. Ballard also disclosed that after "mowing the lawn" with highly advanced technological gear (sweeping his sonar back and forth and checking its soundings with a magnetometer), the expedition had actually located the Titanic with a "25-year-old echo sounder. It could have been done in a fishing boat...
...sailing on the U.S. Navy research vessel Knorr joined forces with a contingent of French scientists aboard the Suroit, operated by the Paris-based Research Institute for Exploitation of the Sea (IFREMER). The two ships bristled with several million dollars' worth of sophisticated equipment. It included a high-resolution sonar device that can trace precisely the contours of the ocean floor, and a compact submersible vessel towed like a sled on a cable, which relayed photographs and videotape confirming the Titanic find. For some of the investigators, the biggest thrill was that their experimental equipment worked. "This allows...
...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 in either direction translates...
...Titanic: Noah's Ark, Bigfoot and the Loch Ness monster. Between 1980 and 1983 he lavished $2 million on three elaborate Titanic expeditions, masterminded by Columbia University Marine Geologist William Ryan and Fred Spiess of the Scripps Oceanographic Institute in La Jolla, Calif. Using prototypes of the Knorr- Suroit sonar technology and submersible cameras, Ryan and Spiess mapped large swatches of ocean floor and took intriguing images of something that Grimm, at least, is convinced resembled the propeller of a ship. Computer enhancement of the pictures, he insists, seemed to show the faintest outlines of bolts. "Only a few ships...
...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 to the mother ship by a thick steel cable. When sonar patterns signal an interesting feature, the video cameras can be commanded to zoom in on the object. The images they pick up are relayed...
