Transcript

  • 1. Antarctica Ms. Patten 2014
  • 2. What is Antarctica like?  The prefix ant- means opposite or opposing  Most southerly continent  Fifth largest continent  Driest, highest, coldest and windiest continent  Antarctica holds 90 percent of all the world's ice and 70 percent of all the world's fresh water.
  • 3. What is Antarctica like?  Antarctica is a large land mass buried under a vast ice cap (98%)  very different from the Arctic which is a frozen ocean surrounded by land  the North Pole is located on shifting sea-ice  In the winter, the temperature at the South Pole averages about -60 degrees C (-76 degrees F).  The farther from the coast one goes the higher and colder it becomes.
  • 4. What is Antarctica like?  The average thickness of the ice sheet is 7,200 feet  If the ice cap were to melt, the average sea level would rise 230 feet, easily inundating most coastal cities: New York, London, and Hong Kong  The weight of the ice is so enormous that the continent buried beneath it would rise to an average altitude of 3,280 feet if the ice sheet were removed
  • 5. Animal life?  Penguins, whales, seals, krill (Norwegian word for whale food) and fish but no land mammals and no native peoples  Polar bears, Eskimos and Santa are found in the Arctic, not the Antarctic
  • 6. Do people live on Antarctica?  There are no permanent residents of Antarctica  Roughly 4,000 scientists and personnel during the summer season; 1000 in the winter  The population at the South Pole peaks when the summer sun is high, reaching 125.  The number of people at the South Pole during the winter of 1993 was only 28.
  • 7. Who owns Antarctica?  No one country actually owns Antarctica although several states have claimed territory  Antarctic Treaty signed by 12 countries in 1959 dictates the use of the continent
  • 8. Australia  The Australian Antarctic Division maintains four permanent research stations; Mawson, Davis and Casey on the Antarctic mainland, and Macquarie Island in the subantarctic.  All four stations are occupied year-round by scientists and support staff.
