Long, a geochemist at Michigan State University, is one of a team of scientists who spent eight days last month exploring Lake Superior in the submersible Johnson-Sea-Link II. Their voyage was the first leg of a four-week, $550,000 expedition sponsored by the National Oceanic and Atmospheric Administration that will continue until Aug. 20. Until now researchers have seldom viewed Superior at depths below 200 ft., generally the limit to which scuba divers descend. But using the Sea-Link, they have been able to plunge right to the bottom. The deepest point...
...scientists and two crew members from the parent research vessel Seward Johnson took turns making the twice-daily three-hour dives in the Sea-Link. Originally built for ocean submersion, the craft had to be packed with a special foam embedded with air-filled glass bubbles to provide the greater buoyancy needed in less dense fresh water. The Sea-Link looks more like an underwater helicopter than a submarine. It has a bubble-like cockpit that seats the pilot and a scientist, and its nine reversible thrusters allow it to move in any direction or hover in place. Cameras...
...underwater exploration was at first plagued with problems, including poor visibility and bursting collection sacks. But after the first two days exploration and sampling went more smoothly. Exulted Long: "We've got rock formations that will knock your socks off !" The investigations planned for the Sea-Link will ultimately involve 27 scientists. Some will survey the spawning habits and conditions of lake trout. Others plan explorations to the wrecks of five ships thought to have sunk between 1880 and 1918 for relics of shipboard life. Because of low water temperatures and the relative lack of oxidation, "the Great Lakes provide...
Scientists hope that findings from the Sea-Link will point to solutions for some of the Great Lakes' continuing problems. With the expedition only a third over, researchers were already counting it a success. Richard Cooper, a marine biologist at the University of Connecticut and the scientific director of the project, declares that before the last dive, "we expect Mother Superior to yield up more of her secrets. We're finding things that will rewrite the book on ecology in the Great Lakes." --By Anastasia Toufexis. Reported by J. Madeleine Nash/Marquette
Within 24 hours of setting out, the travelers were seized by contras. They spent 29 hours in custody before being released unharmed. Every stage of the Witnesses' saga received carefully managed press coverage. Even their capture was recorded, over an open radio link, by a television crew standing by in the Witness for Peace headquarters in Managua...
