Giant icebergs collide off Antarctica

Australia's ABC TV announced today that a gigantic iceberg measuring 78 km long by 39 km wide and 400 meters thick has broken from the tongue of the Mertz Glacier in Antarctica. The calving was due to another berg of similar size colliding with it.

The report stated that this event was not related to global warming but that there could be long term effects from these two giant bodies of ice if they remain where they are. They may have an effect on ocean currents and temperature.

ABC News on-line states: “With an area of more than 2,500 square kilometres, the iceberg is bigger than the Australian Capital Territory [or Luxemburg], and holds enough fresh water to supply all of the earth's human needs for a year.”
That is one big berg!

Having commenced Antarctic studies at the University of Tasmania only this week, I find this event intriguing and the sheer dimensions of this berg mind boggling.
