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.

    The first map from the AAD gives an idea how far the Aurora Australis had to stand off Davis to fly helicopters” – Mercatorised maps are good for many things – but for inter-comparison of distances they’re lousy – especially towards the poles – where they are mostly useless for that task.

  • The Mercator projection distorts latitude, not longitude. As the helicopter is flying almost north south, a Mercator projection accurately shows the distance.

    Using this Latitude/Longitude Distance Calculator from NOAA – I make the distance 156 Nautical Miles or 288 KM.

    Aurora Australis slowed down somewhat and crunching through ice ~66South – trying to get “40-50nm miles from Mawson station”
