The North Pole to Greenland: A Scientific Transect
In April 2012 a team of four set out south from the North Pole, their destination: Greenland, over 700 km away; their aim: the intimate collection of never-before obtained data from beneath the ice; data that could verify the role that a changing Arctic may play in the greater Atlantic circulation,...

In April 2012 a team of four set out south from the North Pole, their destination: Greenland, over 700 km away; their aim: the intimate collection of never-before obtained data from beneath the ice; data that could verify the role that a changing Arctic may play in the greater Atlantic circulation, with implications for the climate of Europe and beyond.
