What was Douglas Mawsons first job?
In 1905 he was made a lecturer in petrology and mineralogy at the University of Adelaide. Mawson’s first experience in the Antarctic came as a member of Shackleton’s Nimrod Expedition (1907–1909), alongside his mentor Edgeworth David.
Who went with Douglas Mawson to Antarctica?
The 32-year-old Mawson left with two younger companions – Xavier Mertz, a Swiss mountaineer and ski champion, and Lieutenant Belgrave Ninnis, a 23-year-old British army officer. With 12 dogs and two sledges, the party headed to the far east of Cape Denison.
What is Douglas Mawson famous for?
Sir Douglas Mawson is one of Australia’s best known Antarctic explorers. His personal Antarctic achievements include discovering the location of the south magnetic pole as part of Shackleton’s Nimrod Expedition, and organizing and leading the first true scientific expedition to Antarctica.
What would Antarctica be like without ice?
The weather will be fairly harsh even without the ice (six month “seasons” of summer sun and winter darkness), and Antarctica gets little precipitation, so will be quite dry and arid.
Was Antarctica a jungle?
Sediment analysis from a layer deep within the Earth revealed that the dirt had first formed on land, not the ocean. A new paper reveals that the frozen continent of Antarctica was once a temperate rainforest.
What does Antarctica really look like?
It is a very rough circular shape with the long arm of the Antarctic Peninsula stretching towards South America. There are two large indentations, the Ross and Weddell seas and their ice shelves. In the winter Antarctica doubles in size due to the sea ice that forms around the coasts.
How long would it take for Antarctica to melt?
If the ice sheet were to melt completely–a process that could take as little as 500 years according to some models–global sea levels could rise by as much as 20 feet, inundating islands and coastal areas worldwide.
What cities will be underwater in 2050?
The Bahamas. Many small island nations will be catastrophically affected by sea-level rises in the future, including The Bahamas, which was devastated by Hurricane Dorian in 2019. Most of Grand Bahama, including Nassau (pictured), Abaco and Spanish Wells are projected to be underwater by 2050 because of climate change.
What happens if Antarctica melts?
If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. Ice actually flows down valleys like rivers of water .
How much will the sea level rise by 2050?
In 2019, a study projected that in low emission scenario, sea level will rise 30 centimeters by 2050 and 69 centimetres by 2100, relative to the level in 2000. In high emission scenario, it will be 34 cm by 2050 and 111 cm by 2100.
Which cities will be underwater by 2100?
Most neighborhoods in Charleston, South Carolina, could be underwater by 2100. Charleston is even more vulnerable to flooding than Atlantic City, with around 64,000 of its residents at risk of coastal flooding in the next 100 years.
Which UK cities will be underwater by 2050?
Huge areas of Cardiff and Swansea in Wales would be left under water, along with almost all of the flat, low-lying land between King’s Lynn and Peterborough on the east coast of England. London, parts of the Kent coast, and the Humber and Thames estuaries are also at risk.
