...undersea salvager, recovery was a different matter. Herndon's vessel went down 100 miles off the Carolina coast, somewhere in sea at least a mile and a half deep. When Tommy Thompson, by the early 1980s a marine engineer at the elite Battelle Memorial Institute in Columbus, Ohio, became interested in undersea mining and salvage, technology for very deep recovery had not progressed much beyond the diving bell. This gadget, first developed in the 17th century, could go deep but do almost no real work...
...they travel 100 ft. or more beneath the surface they're hard to detect directly. So scientists use satellites to pick up the subtle undulations in sea level produced as the ripples pass by. That's how NASA oceanographer Anthony Busalacchi could see early last spring that swarms of undersea waves had started to head out across the Pacific toward the coast of Peru; he followed them as they slammed into the continental shelf, then split, heading sharply south toward Chile and north toward Alaska...
Klimley also discovered what may be the reason the hammerheads school year after year at an undersea mountain known as Espiritu Santo, 15 miles east of the Baja Peninsula. The metal-rich seamount, he found, has a particularly strong magnetic field. So do bands of ancient congealed lava that radiate from the seamount like spokes from a wheel. The hammerheads, he believes, can detect this magnetism and use it for navigation. The seamount is essentially a depot: the hammerheads gather there before going out to their feeding grounds...
...faint electricity generated by another fish's movement, gill action or even heartbeat. Indeed, Holland's team in Hawaii routinely tricks baby hammerheads at Coconut Island into striking at electrodes dangling in the water. Adult sharks, apparently drawn by the same process, have been known to bite through undersea cables. Holland is planning to investigate what sorts of electric signal might repel rather than attract sharks--protecting not just hardware but people as well...
PARIS: Died: Jacques Cousteau, who brought the fantastic, muticolored undersea world of ice formations, shipwrecks and just plain mackerel to America's television masses, after more than 60 years of underwater exploration. "Jacques-Yves Cousteau has rejoined the World of Silence," the Cousteau Foundation succinctly announced, leaving unstated the cause of the 87-year-old oceanographer's death. As a child, Cousteau was notable for his passion for breaking high school windows. As an adult, after completing France's prestigious Naval Academy, he poured that energy into inventing the aqualung, building the first manned undersea colonies, and floating for more...
