...revived its once-faltering reputation, and many future plans revolve around seeding everything from tornadoes to typhoons. The Soviets are testing sound as a possible way to disperse fog, have even suggested damming the Bering Strait to make the Arctic warmer. Several countries have suggested melting part of the icecap by coating it with heat-absorbing carbon. U.S. scientists are considering the possibility of generating dust clouds in space to form sunshades, or creating broad bands of ice-crystal cirrus clouds that would allow the ground beneath to cool...
...scalped himself and suffered cerebral concussion and a fractured spine. Because his legs were paralyzed, McMullen was placed in traction, and word was flashed to Washington that an immediate operation was necessary to save his life. There are no surgeons among the reduced 215-man winter staff on the icecap, and the Navy ordered a U.S. surgical team to risk the dangerous flight...
Floating Shelf. Unlike the northern polar region, which is ocean covered with ice, the area around the South Pole is a large land mass above which a thick icecap can form. During relatively nonglaciated periods such as the present, Dr. Wilson calculates, ice builds up on Antarctica, and the southern icecap reaches higher and higher. The top of the ice remains very cold, but the bot om is warmed slightly by heat escaping from the interior of the earth. Finally, the combined effect of pressure from the thickening cap and geothermal warming below melts the ice at the bottom. This...
Nibbling Ocean. This is what happened about a million years ago at the beginning of the Pleistocene, and the earth might have remained forever in perpetual deep freeze if not for a hid den weakness of the Antarctic icecap. As the ice spread out over the southern ocean, colder ice came in contact once more with the rock below it, freezing the slippery water layer between ice and rock (see diagram). This was the turning point. Held fast to the rock, the ice stopped moving. The ice shelf was nibbled away by the ocean, and the earth could capture more...
Antarctica's vast (5,300,000 sq. mi.) expanse, comprising 93% of the world's ice, offers an unsurpassed observatory for study of the oceans, which would rise 200 ft. if, as some predict, the icecap should melt in some far distant age. Scientists have already learned a great deal about its climate and its far-reaching effect on the world's weather. Oceanographers are studying Antarctica's seas, which are among the world's most fertile areas...
