Tour of Norwegian Arctic science ship Lance

The Arctic is entering what is being described as "a new era" as temperatures rise and the ice covering the ocean becomes thinner, according to scientists taking part in an expedition run by the Norwegian Polar Institute.

Since the start of the year, the research vessel Lance has been drifting in the ice-pack to give scientists the chance to investigate how this region is changing.

The BBC's science editor David Shukman took a look around the ship's bridge, sleeping quarters and laboratories for a taste of life on board.
