...Smithsonian Institution's Museum of Natural History in Washington and John H. Prescott of Boston's New England Aquarium, the worms had apparently been taken in along with meals of fish or squid. Once entrenched, they may have interfered with the whales' highly sensitive, sonar-like echo-location system, which enables them to spot schools offish and other objects. The whales' hearing is an essential part of the system, and if it is badly impaired, the scientists say, the whales can neither locate any prey nor avoid hazardous shoals or beaches...
...team of oceanographers has located the Monitor in a storm-swept spot 15 miles southeast of Cape Hatteras, at a murky depth of 220 ft. Using sonar equipment to locate the site and an underwater television camera to photograph the ship's remains, the team has pieced together portions of video tape to confirm that the Monitor's broken hull lies upside down in the water, partly buried under 3½ ft. of sediment. But the ruins of the ship are so fragile that attempts to lift them from the ocean depths would probably cause the 112 year...
...Politician Ishihara Shintaro has set out to track down, photograph and perhaps even trap the legendary beast. The Japanese are not stinting in their efforts. The vanguard of the $500,000 expedition has already arrived on the scene; soon the hunters will begin using such formidable weaponry as a sonar-equipped minisubmarine and tranquilizing guns...
...trees, animals and sunrises. "There is nothing that lives or grows," says Submarine Medical Officer William Tansey. "It is all flashing lights, air conditioning and bells. You lose your grasp on the real world." One result aboard submarines on long missions is that sailors vie for space in the sonar room to hear the mating calls of whales or swimming noises of shrimp...
...from San Diego, Calif.-the men had been under water 26 hours. The bell also snagged in debris. One of the divers then tried to swim to the sub, but he could not make headway against the 2½-knot current. Hindered by debris and problems with its sonar gear, a little submersible called a Cubmarine had no better luck. Just as the situation seemed hopeless, the research ship A.B. Wood arrived, equipped with a remote-controlled underwater television camera. Using the camera to guide a grappling hook, the Wood managed to snare Sea-Link; a single tug freed...
