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 the United States，Switzerland，and France are 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 Mountain，Some of them more than 14，000 feet high，divide the continent into two very different regions.The part of the continent 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 the Americas is 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 disappeared，the western part of the continent would be reduced to a sparse cluster of island.
