What Mawson achieved?
Antarctic achievements Along with his mentor Professor T.W. Edgeworth David, Mawson completed the longest Antarctic man-hauling sledge journey of 122 days. Coping with hunger, hidden crevasses, frostbite and exhaustion, they received a hero’s welcome on their return.
How did Mawson survive?
The accident left Mawson and Mertz with 10 days’ food supply for a journey back to base that would take at least a month. As they retreated, Mawson severely rationed the remaining food. They also started to kill the dogs- eating the “best” bits themselves and feeding the rest to the remaining dogs.

The Longest Non-Polar Glaciers In The World
|Rank||Glacier||Length (in km)|
How tall is the average glacier?
Glaciers cover about 10% of Earth’s land surface. Continental glaciers cover nearly 13 million km2 (5 million sq mi) or about 98% of Antarctica’s 13.2 million km2 (5.1 million sq mi), with an average thickness of 2,100 m (7,000 ft).
Why is glacier water so blue?
A large piece of compressed ice, or a glacier, similarly appears blue. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end of the visible spectrum.
Is it safe to eat glacier ice?
Answer 3: If you eat snow or ice that has enough microorganisms to give it a color (e.g. pink), then it will give you diarrhea. Otherwise, snow and ice are generally safe to eat.
Why should you not drink glacier water?
Think that ice-blue water pouring out of a beautiful mountain glacier is safe to drink untreated? Think again. The research suggests fecal bacteria can survive inside glaciers for much longer than previously thought, flowing downhill with the ice, and potentially infecting water sources tens of miles away.
What is the black stuff in glaciers?
The dark dust, which is spread over glaciers in Greenland and other icy areas of the world by wind and rain, is composed of mineral dust from warmer regions of the world, rock particles from volcanic eruptions, and soot from fires, the emissions of our cars and coal-fired power plants.
