Glancing at his watch, the leader signaled to the others, and the trio, using their flippers to rise, promptly began their ascent by following a cable that led up to the Virazon. Reaching a white marker cylinder at the 20-ft. depth, they stopped, treading water for three minutes, before rising again to a second marker, at the 10-ft. level. There they waited for eleven minutes, passing the time by penciling messages to each other on a roughened Plexiglas tablet. The scheduled pauses were decompression stops that allowed the excess dissolved nitrogen to leave their bodies gradually...
...National Geographic, the venerable publication of the National Geographic Society, which has since financed many undersea missions by Cousteau and others. In 1959 Cousteau invented the first small submersible, a battery-powered diving saucer propelled by jets of water that could safely carry a two-person crew to a depth...
...Navy had launched the first, and still most famous, of the new submersibles, Alvin. Operated by Woods Hole, the 23-ft.-long craft could carry three people to a depth of 6,000 ft., pick up objects with an arm and claw, and roam the sea floor at a speed of one knot (Alvin has since been lengthened to 25 ft. and given a second arm-claw, as 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...
...years, Alvin has been joined in the seas by dozens of other manned submersibles, most of them American or French. The deepest operational diver of them all is the U.S. Navy's 31 1/2-ft., 58,000-lb., three-man Sea Cliff, which can safely carry its crew to a depth of 20,000 ft. Its manipulator arms can operate a variety of underwater tools, including a drill, a cable cutter, scissors, and plier-like jaws that can grasp sunken torpedoes, as well as attach cable slings to raise heavier objects such as downed aircraft...
Even some of Reagan's supporters feel he made a basic political misjudgment by jumping into the debate over sanctions with nothing new to offer at a time when something more was needed. He seemed also to misread the depth of sentiment on the issue. While just about everyone is repelled by the oppression in South Africa and thinks something should be done about it, there is no clear consensus on what. Reagan, by heightening the visibility of the subject without offering a solution, succeeded only in exposing his own policies to closer inspection and greater criticism...
