Several definitions of the Arctic as a region exist and are all used extensively. Definitions of the geographic boundaries of the Arctic vary, including such definitions as the area with a July isotherm below 10º C, vegetation distribution (tundra) or political boundaries, such as the definition by CAFF (CAFF, 2001). Nowhere else on Earth do we find such vast areas of relatively undisturbed marine and coastal ecosystems.
