In Iceland we track Icelandic ponies half-wild half tame as they race in a herd across icy landscapes. In this land of ice and fire there’s a spectacle aplenty with gushing geysers and volcanic fury all washed by the brilliant colours of the world’s untamed light show the Aurora Borealis.

In Greenland, we track hardy fishing boats as they battle through thick ice sheets. Our cameras explore grinding glaciers and formidable icebergs.
