Sailing the North Pole: This is a documentary about the expedition of Sebastien Roubinet et Rodolphe André who have decided to cross the Arctic Ocean from Alaska to the Norwegian islands of Spitsbergen, via the geographic North Pole! For this, Sébastien Roubinet has invented a strange little boat "TiBabouche" capable of sailing on sea and on ice. This boat is a prototype brimming with technology and science, made-up by Hervé Le Goff, a CNRS engineer. It will allow Hervé to calibrate the satellite “Cryosat”, the first one capable of measuring the thickness of ice.
