Australian Antarctic bases Davis and Mawson beset by ice

The first map from the AAD gives an idea how far the Aurora Australis had to stand off Davis to fly helicopters – and we are only at the autumn equinox. Note too the current search area for debris ex MH370 is on that map.

  2. The Mercator projection distorts latitude, not longitude. As the helicopter is flying almost north south, a Mercator projection accurately shows the distance.” – precisely my point Phillip. The relative distances between Mawson, Davis and Casey do not scale to the distance to ship.
