American scientists said Wednesday that they had found a tantalizing new energy source in vast stores of methane locked beneath the ocean floor. They report in Nature that they found a reservoir of methane in the form of a solid gas hydrate equivalent to about 15 billion tons of carbon at Blake Ridge in the Western Atlantic. Underneath that, to their surprise, they found as much or more methane in the form of gas bubbles amid the sediment.

An underwater robot wiggles its tiny, boxlike body 60 feet underwater to peer over volcanic terrain, while another focuses in on feeding sharks and a third quietly eyes the coral and waits to zoom in on the ocean creatures' next stir. Starting Monday and continuing for two weeks, half a million children in 20 locations across North America will sit transfixed before three huge TVs, watching live transmissions of the robots' underwater exploration.

Powerful volcanic eruptions over the last century have slowed the rise in sea level by releasing fine particles that deflect sunlight, cooling the oceans and thus reducing their volume, according to a study published Thursday in the journal Nature. But the effect is only temporary. Using computer models and satellite data, researchers found that the 1991 eruption of Mt. Pinatubo in the Philippines dropped sea levels by about 5 millimeters, or a fifth of an inch, within a year.

An underwater acoustic signal was heard across the globe this week, marking a milestone in an experiment that researchers hope will make it easier to detect warming of the world's oceans from the greenhouse effect. Sounding like an underwater foghorn, five transmitters suspended 600 feet below a U.S. Navy ship in the southern Indian Ocean began booming every three hours, for one hour at a time, last Saturday.

His rough-cut hair and beard shine silver like sunlight off water. His eyes are dappled with hues of the reef. He wears a dive-suit sewn in shades of ocean blue. His name seems derived from the sea, too: Cousteau. When he splashes off the stern of a dive boat, Jean-Michel Cousteau folds at the waist. His arms draw to his side. His swim fins flex and bite into the water. He is fluid, streamlined, serene. A cascade of chrome bubbles rise from the scuba regulator in his mouth.

Scientists seeking to transmit loud sounds through the Pacific Ocean to measure global warming defended their experiment Wednesday, insisting that the noise would not deafen whales and pledging to halt the project if it appeared to be causing harm. "We are not out to harm a single whale with these underwater sounds," said David Hyde, director of the research project at Scripps Institution of Oceanography in San Diego. "We will cease sound transmissions to avoid harm to marine mammals."

For more than three hours last week, delegates to the world body responsible for the global ban on killing whales for profit discussed more efficient and painless ways to do just that. Norway recommended its new harpoon-borne, high-explosive grenade fired deep into the whale's brain, noting in a scientific report that 63% of the 625 whales it killed that way last year died instantly. Japan said a .

A national panel of scientists has recommended immediate and substantial reductions in ocean fishing to rebuild marine ecosystems throughout the world that are so severely depleted they are in danger of collapsing. The total volume of fish being caught has reached or exceeded the maximum amount that can be sustained by the world's oceans, the scientists reported. About 84 million metric tons of fish and other seafood are caught each year in marine waters worldwide, worth about $3.

President Clinton will unveil a plan today intended to permanently protect coral reefs in the northwest Hawaiian Islands and set a course that would ban fishing, offshore drilling and other activities from sensitive ocean waters, a White House official said Thursday. Clinton will order the Commerce and Interior departments to designate "marine protected areas," marked by diverse marine ecosystems.

"It's tougher than weather, clear as crystal, flexible as paper and can even transform baby breaths or speeding stardust into tiny electrical signals that you can keep an eye on." That's what engineer Victor Chatigny of Penwalt Corp. in Valley Forge, Pa., might say if he made a television ad for a seemingly does-it-all plastic that his company sells as Kynar Piezo Film.
