  2. Warm-Up: What do you know about Antarctica?

  3. Geography

  4. Climate • Coldest and windiest continent • Lowest recorded temperature -89.2C or -128.6F (1983) • Wind speed of 320 km/h (200 mph) • Calm periods last a few hours • “katabatic winds” winds that flow downwards from the interior toward the coast driven largely by gravity

  5. Climate • Three climate regions • 1. Interior extremely cold with little snowfall • 2. Coastal Areas milder temperatures and much higher precipitation rates • 3. Antarctic Peninsula warmer and wetter climate, above-freezing temps in summer

  6. Antarctic Landscape • More than 98% covered with ice • 70% world’s fresh water • Two main areas 1. East Antarctica 2. West Antarctica- extended of Andes Mountains • Transantarctic Mountains- mostly covered under ice • Rigid, glaciers and ice sheets • Classified as a desert- snow piles up, Sahara desert gets more rain

  7. Plants and Animals • Mosses and algae • Whales • Seals- Leopard Seals • Penguin • Fish/Krill

  8. Who lives there? • No native population or permanent residents • Whalers and sealers first people to set eyes on Antarctica • Research bases

  9. Antarctic Treaty • 1961 Antarctic Treaty claiming territory from many nations, peaceful scientific investigation • Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, Russia, United Kingdom, United States • First arms control agreement during Cold War • Headquarters in Argentina since 2004
