text: # 30th meridian west
  
  The meridian 30° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Greenland, the Atlantic Ocean, the Southern Ocean, and Antarctica to the South Pole.
  
  The 30th meridian west forms a great circle with the 150th meridian east, and it is the reference meridian for the time zone UTC-2.
  
  Between the 45th and 61st parallels north, the meridian forms the boundary between the Gander and Shanwick Oceanic air traffic control areas, and for this reason is also known as the "Molson-Guinness Line".
