Aerial view of the rarely-visited, volcanic Balleny Islands, taken during the second leg of the Antarctic Circumnavigation Expedition (ACE). Their location straddling the Antarctic Circle gave scientists the perfect opportunity to drill the first ice core from Young Island to better understand changes in circumpolar westerly winds.
