- <p> Think of them as a matched pair of undersea loudspeakers, one
- sunk off the coast of California near Big Sur, the other near
- the Hawaiian island of Kauai. A blast from one of these big
- woofers would be loud enough to be heard in the water for thousands
- of miles and loud enough to damage or destroy the hearing of
- any animal that swam too close.
- </p>
- <p> That's a problem for some marine biologists and a lot of whale
- lovers. Both groups came to Washington last week to speak out
- against an experiment involving the boom boxes. The $35 million
- project, set up by San Diego's Scripps Institution of Oceanography,
- is designed to find out whether the much feared global warming
- is actually occurring. At regular intervals over a period of
- years, scientists will fire acoustic "shots" across the water
- and measure the time it takes them to span great stretches of
- the Pacific. Since sound moves faster in warm water than in
- cold, researchers will get an indirect indication of ocean temperature.
- The experiment will begin next month if the government grants
- an exemption to a law protecting marine mammals from harassment.
- </p>
- <p> The dispute pits environmentalists against one another: those
- who worry more about global warming vs. those who fret more
- about animal welfare. Lindy Weilgart, a Cornell University expert
- on whale acoustics, pointed out at hearings before the National
- Marine Fisheries Service that whales and other marine mammals
- rely on exquisitely sensitive hearing for hunting, navigating
- and socializing. Noise pollution from the experiment, she fears,
- could disrupt the mating and migration patterns of hundreds
- of thousands of animals. As Weilgart put it, "A deaf whale is
- a dead whale."
- </p>
- <p> Proponents argued that few creatures would swim close enough
- to be deafened by the speakers, which will be anchored 3,000
- ft. deep. Moreover, supporters said, the noise would be no louder
- than other sounds filling the sea, from the thunder of cracking
- polar ice to the roar of supertankers.
- </p>
- <p> By week's end many marine biologists had been persuaded that
- the project was acceptable, and government approval seemed likely.
- The Scripps Institution, for its part, has set aside $2.9 million
- to study the experiment's effects on marine mammals and promises
- to pull the plug on the loudspeakers the minute the neighbors
- complain.
