...when French Undersea Explorer Jacques Cousteau explored the Sargasso Sea, he could see underwater for about 300 ft. Today, he reports, the visibility has shrunk to barely 100 ft. When he first started diving in the Mediterranean 25 years ago, it was filled with life. Today? "You can hardly see a fish 3 in. long." What has happened is that pollution has caught up with the seas' and oceans' ability to cleanse themselves. Cousteau estimates that the vitality of the seas, in terms of fish and plant life, has declined some 30% to 50% in the past...
...seabed out to a limit of twelve miles or until the water depth reaches 650 feet, whichever point is farthest offshore. Beyond the limit of seabed rights and up to the edge of the continental shelf, the local government would act as a trustee, licensing and taxing such undersea operations as mining and drilling; a certain share of the proceeds, perhaps 50%, would be distributed to underdeveloped countries. An international tribunal would also consider applications for special fishing rights...
Whatever tack the U.S. decides upon, SALT does not have forever to show results. U.S. experts point out that 18 to 24 months from now the Administration will be under pressure to decide whether or not to go ahead with the undersea long-range missile systems (ULMS) and the B-1 supersonic bomber. Unless a SALT agreement is reached, still another lap in the arms race is almost sure to begin...
...classical geophysical theories. Although it was once thought that the ocean floor has remained stationary and relatively unchanged for billions of years, scientists are now certain that it is continually spreading and being renewed with fresh material welling up from a 47,000-mile-long chain of volcanically active undersea ridges. As this new rock from deep within the earth's mantle moves slowly away from the mid-ocean ridges, it carries the continents along, thereby providing the mechanism for continental drift (TIME, Jan. 5, 1970). Millions of years after leaving the ridges, the material reaches the extremely deep...
...scientists finally agree, for example, that the continents-which look as if they once fitted together like a giant jigsaw puzzle-indeed broke off from one or two immense land masses along volcanically active cracks in the earth's crust known as mid-ocean ridges. Part of this undersea mountain chain, which girdles the earth like stitching on a baseball, has now been identified as the prime suspect in still another major geological mystery: the raw and atypical terrain of the American West...
