America,between them is Drake Passage(德雷克海峡德雷克海峡).The Antarctic continent and other continents are not only far apart,but also surrounded by a number of kilometers of ice shelves(冰架冰架),In winter the area is up to 19 million square kilometers;even in the Antarctic summer,it also has 2.6 million square kilometers;the waters around the Antarctic continent are also covered by thousands of huge floating icebergs(冰山冰山),causing great difficulties and dangers for maritime navigation.11DiscoveryThe old ice core which was found by Japanese Antarctic observation team on January 26,2006 at the South Pole station near the base,which is under 9994 feet in the Antarctic ice,ice core contains many air bubbles(气泡),these bubbles are most likely to stay millions of years ago.It will not only help us to understand the Earths past environment but also can be used to predict future climate through careful research.It has been estimated that this may b
