The Arctic survey's ice penetrating radar

A global team of scientists and Arctic explorers hopes to accurately predict the lifespan of the Polar ice cap

ClimateChangeCorp interviewed Pen Hadow, leader of the Arctic Survey, about both the science and the politics behind the expedition.

Background: In Spring 2009, three Arctic explorers will attempt to accurately measure the thickness of the polar ice cap for the first time in history. Scientists intend to use the data to predict, more precisely than ever, when the Polar ice cap will disappear.

The explorers will drag an ice penetrating radar behind them on a 2,000 km trek from Alaska to the North Pole, measuring the thickness of the ice beneath as they travel.

Until now, scientists have only been able to use estimations from submarines and satellites in Arctic models. The predicted date of meltdown currently ranges from five to 100 years from now.

Participants in the Arctic Survey include: NASA, the European Space Agency, the US Navy, the University of Cambridge and the UK Met Office.

The results of the survey and predictions of the meltdown date will be presented to politicians at the UNFCCC Cop 15 international climate change meeting in Copenhagen at the end of 2009.
