Profile - Pen Hadow

Mary Ann Sieghart profiles the Polar explorer Pen Hadow, who is leading the Catlin Arctic Survey to determine the likely meltdown date of the ice cap. The British trailblazer and his team will drag a mobile radar unit more than 1000 kilometres as they trek to the North Pole. Hadow, a self-confessed 'tortured soul', has been criticised by some in the past for his so-called reckless behaviour. But his current trip, he insists, is not about exploration, but about gathering scientific data that could be crucial to our understanding of climate change. Mary Ann hears from friends and family of this enigmatic explorer.
