Adam is 78 degrees north in the remote Arctic Svalbard archipelago at the world's most northern fine dining restaurant, Huset. Adam meets Jason Roberts, an Australian who has lived in Svalbard for 20 years, before entering 1930's Moelven wooden barracks adorned with mining and hunting memorabilia. Here Adam makes the famous Norwegian salmon gravadlax before completing his trip at the Global Seed Vault. With its aim to protect the world's food resources, the vault keeps a back-up copy of the world's agricultural seeds so they may remain safe from man-made or natural disasters.
