Swedish House

This video continues the historical theme of this year's Christmas edition. We follow an intrepid group of Norwegian scientists and historians as they travel to the frozen tundra of Svalbard, an island in the Arctic Ocean. There they investigate the death of a group of seal hunters who were stranded on the island in 1872 – the official cause of death was scurvy, but Ulf Aasebø and his team reach a different conclusion.
