...bass tournament on Alabama's Lake Guntersville earlier this month seemed more like the Indy 500. Some 320 anglers set out in their boats at 5 a.m., battling the morning chill and 3-ft. waves in pursuit of fish and fortunes. The competitors were equipped with the latest in sonar and trolling motors, the better to pursue their wily prey. When the anglers returned to shore, crowds gasped in excitement as judges weighed the catch and flashed the results on a digital screen. The winner, Robert Byrd of Zwolle, La., brought in 60.7 lbs. of bass in just three days...
...Navy has its way, the Trident nuclear-submarine base at Bangor, Wash., will soon be guarded by an uncanny underwater-surveillance system. Vastly more powerful than the Navy's most sophisticated sonar, it can identify real threats to the base, distinguishing them from the normal cacophony of noise in the cold, murky waters of Puget Sound. Developed at a cost of nearly $30 million, it can spot and tag intruding divers, making it possible for them to be intercepted, and can outmaneuver any underwater machine. Yet just about the only maintenance required is 20 lbs. of fish...
...concealed objects by sound waves, electronic signals or other means -- has dramatically changed the study of the oceans. Scientists are now able to see things that they could only grope at before. This is made possible not only by a satellite's panoramic perspective but also by new sonar techniques that peer through waters that are miles deep. Oceanographers who once devoted years to analyzing information from infrequent research trips are deluged with data that are yielding the secrets of earth's last frontier...
...civilian counter-espionage agency. But the most sensitive target was Montreal-based Paramax Electronics, a subsidiary of the U.S. defense contractor Unisys and the prime subcontractor on a frigate- building project for the Canadian navy. In that role, Paramax has access to highly classified American technology involving radar and sonar capabilities and computers that control shipboard weapons systems...
...Seawolf's high-tensile steel hull will withstand pressures of 100,000 lbs. per sq. in., permitting the sub to dive to depths between layers of water at different temperatures where it can hide from enemy sonar. When it comes time to surface, not even the polar ice cap will be able to keep the Seawolf down. The low, streamlined sail -- conning tower to landlubbers -- will be hardened to absorb the shock of breaking through the ice. Retractable bow planes will permit the Seawolf to navigate under the Arctic, the huge (5.4 million sq. mi.) new battleground of underwater...
