...Cyana explored one of the earth's last great frontiers: the rugged, seismically active rift valley that cleaves the floor of the Atlantic almost all the way from the Arctic Ocean to Antarctica. Last week, as the scientists who took part in FAMOUS (for French-American Mid-Ocean Undersea Study) returned home from their expedition to the bottom of the sea, they reported that their little craft had discovered important new clues to the secrets of continental drift...
Although the scientists were somewhat disappointed by their failure to see an actual undersea eruption of lava, the expedition was not without its excitement-or perils. Frequent landslides along the walls of the valley were a constant threat to the three ships; if their shells had been ruptured by tumbling rock, the crushing pressure of the water (two tons a square inch) would have meant quick death for the crews. All three submersibles were also bothered by minor mechanical difficulties; Alvin's final two dives had to be scrubbed because of an electrical problem. Even so, the performance...
...State Department came up with a compromise in 1970. Then Under Secretary of State Elliot Richardson proposed that all coastal nations be allowed to extend control of offshore waters to a depth of 650 ft. Seaward from that point, they might develop undersea oil or ore reserves, but only as "trustees" for a so-called seabed authority representing the international community, which would reap up to 50% of the profits from deep-sea exploitation...
That leaves the really troublesome issue: undersea resources. In the case of oil and natural gas, the problem would be settled relatively simply by the 200-mile economic zone. Virtually all of the accessible oil and gas reserves lie within this zone, leaving coastal states in control of their own offshore deposits. But how to deal with deep-sea minerals...
...recently had all but wiped out Peru's valuable anchovy harvest, is apparently linked to the great north equatorial countercurrent that sweeps from the Philippines to Central America. British and American scientists have been taking part in a similar study in the Atlantic, concentrating on the mysteries of undersea eddies, or storms. Meanwhile, oceanographers aboard the U.S. deep-drilling ship Glomar Challenger, which has been poking into the sea bottom for the past five years, have come up with hard evidence for a revolutionary new theory called "global tetonics." It holds that theory the continents are drifting ever...
