A Antarctica has actually become a kind of space station―a unique observa?tion post for detecting important changes in the world's environment. Remote from major sources of pollution and the complex geological and ecological sys?tems that prevail elsewhere,Antarctica makes possible scientific measure?ments that are often sharper and easier to interpret than those made in other parts of the world.
Growing numbers of scientists therefore see Antarctica as a distant-early-warning sensor,where potentially dangerous global trends may be spotted before they show up to the north. One promising field of investigation is glaciology. Scholars from theUnited States,Switzerland,andFranceare pursuing seven separate but related projects that reflect their concern for the health of the West Antarctic Ice Sheet—a concern they believe the world at large should share.
The Transantarctic Mountains,some of them more than 14,000 feet high,divide the continent into two very different regions. The part of the con?tinent to the "east" of the mountains is a high plateau covered by an ice sheet nearly two miles thick. "West" of the mountain,the half of the continent south of theAmericasis also covered by an ice sheet? but there the ice rests on rock that is mostly well below sea level. If the West Antarctic Ice Sheet disap peared,the western part of the continent would be reduced to a sparse (稀疏的) group of island.
While ice and snow are obviously central to many environmental experi?ments,others focus on the mysterious dry valleys of Antarctica,valleys that contain little ice or snow even in the depths of winter. Slashed (挥砍) through the mountains of southern Victoria Land,these valleys once held enormous glaciers that descended 9,000 feet from the polar plateau to the Ross Sea. Now the glaciers are gone,perhaps a casualty of the global warming trend during the 10,000 years since the ice age. Even the snow that falls in the dry valleys is blown out by vicious winds that roar down from the polar plateau to the sea. Left bare are spectacular gorges,rippled (起伏的) fields of sand dunes,groups of boulders (卵石) sculptured into fantastic shapes by 100-mile-an-hour winds.
Despite the unearthly aspect of the dry valleys,some scientists believe they may carry a message of hope of the green parts of the earth. Some scien?tists believe that in some cases the dry valleys may soak up pollutants faster than pollutants enter them.
