2  Description
  The Amundsen‑Scott South Pole Station (South Pole Station) is located on the polar plateau near the geographic South Pole, at 90° S. An area of approximately 26 400 km2 encompassing the station and long‑term research and monitoring sites is designated as an ASMA to manage human activities for the protection of scientific, environmental, and historical values.
  The boundary of the ASMA comprises all structures and areas of current and planned research at South Pole Station and a buffer area for the Clean Air Sector (CAS). The boundary of the ASMA is a circle around South Pole Station with a radius of 20 km, and a wedge extending 150 km from the Atmospheric Research Observatory (ARO) building (approximately 0.5 km from the 2005 Geographic South Pole), bounded by 110° and 340° (grid) from the ARO building. The point of origin of the ASMA and sectors (other than the CAS) was designated as the circular aluminium tower staircase on the elevated station, as this is a readily recognizable feature on the maps and on the ground, and the elevated station is expected to be present in the ASMA longer than any other structure or landmark.
  Due to the movement of the ice sheet in the area, the geographic location of the ASMA will move approximately 10 m per year; the area is centred on the elevated South Pole Station, and all sectors are relative to this location.
