  3. Nations that claim Antarctica

  4. Antarctica Treaty • The Antarctic treaty is a agreement that countries sign to approve that they will keep Antarctica safe and healthy. The agreement was open for nations to sign in 1959,but fully enforced in 1961. So far 12 nations have signed the agreement and also 47 countries have signed the agreement as well.

  5. Sir Douglas Mawson • Sir Douglas Mawson was born on 5th of May 1882 and past away in 14 October 1958 he died at the age of 76. He was born in England in Shipley Yorkshire and moved to Australia with his family at the age of 2. In his early life he was a Geologist, Antarctic Explorer, and an Academic. Douglas Mawson said no to a invitation to go to Antarctica with Robert Falcon Scott but Mawson was still determined to go so he set out by himself to lead his own expedition. Douglas wanted to go to the South Magnetic Pole so he set out on a sailing boat(SY Aurora) commanded by Captain John King Davis and departed out from Hobart on the 2 December 1911. Douglas landed at Cape Denison on Commonwealth Bay on 8th of January and built a main base. Mawson's explorers built a rocky hut and stuck through nearly every blizzard. From 1911 to 1914 he commanded the Australian Antarctic expedition. He studied the Antarctic Cape Adare, He also spent two whole winters in Adelie Land, and discovered King George V Land, Whilst his team also discovered Queen Mary Land. On his harsh trip two of his crew man died ( Xavier Mertz and Lieutenant Belgrave Ninnis) and he could not save them, Douglas could barely save himself. http://en.wikipedia.org/wiki/Douglas_Mawson http://www.factmonster.com/ce6/people/A0832303.html

  6. Animal Report: Blue Whale • Info: Blue whales are the biggest mammal on Earth maybe even bigger than some dinosaurs, it belongs to the family of Rorquals and also Baleen Whales. They are endangered and nearly hunted to extinction in 1960s due to whaling. It’s estimated that there are about 6000 Blue Whales left. • Description: The Blue Whale has a Grayish-Blue appearance with gray spots across it enormous body. It has a small dorsal fin low on it’s back. The average length of a Blue Whale is about 75-80 feet (22-24 Metres) but the female which is the biggest of their kind can grow 80 feet and can weigh 100 TONNES! • Location: Blue Whales can be found all over the world. They migrate to warmer waters in winter, in tropical and subtropical waters. They go to colder waters in spring and summer. They travel in very small groups (also known as ‘’pods’’) usually travelling alone. Blue Whales can move very fast sometimes they can reach speeds up to 30kph. • Diet: Blue Whales eat by filtering their food from the water and sieve through their baleen. They have large grooves to allow their belly to expand to take large amounts of food then it’s pushed through baleen leaving the food behind to eat. Their main food source is Plankton and Krill( Krill is similar to prawns.) Blue Whales can eat over 4 tonnes of these animals per day during summer season.

  7. Animal Report: Blue Whale • Breeding: The female Blue Whales give birth once every two to three year period after their year long gestation. The Calf is looked after for 6 to 8 months then it will stay with it’s mother for a year. The whales will reach sexual maturity at the age of 10. Calf's usually live for about 35-40 years but some whales have reached the age of 80. • Communication and Info: Blue Whales were once called ‘’Sulfur bottoms’’ by the whalers of the earlier centuries because of the micro-organisms and also algae that grow on it’s belly showing a yellowish appearance. The Whales communicate by clicking, moaning and buzzing. Because of this they maybe classified the loudest animal on the planet. The noise is that high pitched that it can reach 150 decibels which can be from hundreds miles under water. http://www.australianfauna.com/bluewhale.php

  8. Did You Know? • The nearest countries to Antarctica are South America, Africa and Australia. • The sun never rises, so it’s dark all the time. The only light comes from the stars and moon. • The temperature is very cold as 70c below freezing. • Antarctica seaweed have adapted to life in cold waters where the surface temperature is 0c(32F) • Because of whaling scientists think that there are about 6000 Blue Whales left. • The wind speed in Antarctica can reach 180km an hour.

  9. The Sun In Antarctica • When it’s January and March there is heaps of daylight—twenty-four hours a day! In September, the Sun rises, and then it doesn’t come and set again until March • http://www.amnh.org/education/resources/rfl/web/antarctica/s_cycles.html.
