Portfolio 4-Ice Sheet


the Eastcoast of the Greenland



An ice sheet is identigied as a plenty of glacier ice which covers surroundings Antarctica and the Greenland have the only current ice sheets.The surface of the ice sheet is cold, but the base is warmer, so melting at the bottom occurs to help the ice sheet’s flowing. Because of rapid devevlopment of the continental glaciaiton in the Greenland, the fossils of plants are protected well.The Greenland ice sheet covers 80% of the surface of the Greenland, which is the second largest ice body in the World, Most of the ice occurs in the central area of Greenland. the mountains occur around which prevents the sheet go across its boundaries in case of the disapperance of ice sheet.The population in the Greenland congregate along the Western coast, which has no ice exist. The culture of Greenland is much similar with Inuit tradition because majority of people are the generation of Inuit. People still remain some traditional activities, suchias go ice-fishing and celebrate annual dog-sled races.Nevertheless, even though fishing has been gradually replaced by the use of modern technology today, the fishing industrial is dominant in the Greenland as well as the mineral exploration. Recently, Tourism is gradually developed and seen as a potential industrial. However, it is still limited by the short acceptable season and high cost.The lossing mass of the ice sheet in the Greenland becomes seirous, which can directly reflects the level of global warming.The scientific expedition stations have already established to help to observe and measure the sea level rise.
