Kunlun Station

Kunlun Station. It is a Chinese summer-only research facility located at the highest point on the Antarctic ice sheet. Established by the Polar Research Institute of China during the 25th Chinese Antarctic Expedition, the station enables unique astronomical, atmospheric, and glaciological observations. Its position at the summit of the East Antarctic Ice Sheet makes it one of the most remote and extreme scientific outposts on Earth.

Overview

Commissioned in early 2009, the station represents a major achievement for the Chinese Antarctic Expedition program under the broader framework of the Antarctic Treaty System. The facility is named after the Kunlun Mountains, a significant mountain range in Chinese mythology and geography. Operations are managed by the Chinese Arctic and Antarctic Administration, with support from agencies like the China Meteorological Administration. Its establishment solidified China's presence in the continent's interior, joining other inland stations such as Amundsen–Scott South Pole Station and Vostok Station.

Location and construction

The station is situated at Dome Argus (Dome A), the summit of the Antarctic Plateau, which is considered the coldest and driest region on the planet. This site was identified as optimal for astronomy following surveys by international projects like the International Polar Year. Construction was a formidable logistical challenge, requiring traverses from the coastal Zhongshan Station across the treacherous Transantarctic Mountains. The main building, assembled from prefabricated modules, is designed to withstand temperatures below -80°C and the fierce katabatic winds of the Polar plateau.

Scientific research

The primary focus is on frontier astronomy, taking advantage of the exceptionally clear, dry, and stable atmosphere. Projects include the Chinese Small Telescope Array and the Antarctic Survey Telescope, which contribute to studies of exoplanets and variable stars. The site is also pivotal for deep ice core drilling, aiming to retrieve climate records over a million years old, rivaling work at Dome C and the European Project for Ice Coring in Antarctica. Additional research encompasses studies of the Earth's magnetosphere, cosmic rays, and atmospheric physics in collaboration with institutions like the University of New South Wales.

Operations and logistics

All personnel and supplies are transported during the brief summer season via overland traverse from Zhongshan Station on the coast, a journey supported by heavy Caterpillar Inc. tractors and air support from Basler BT-67 aircraft. The station operates completely unmanned during the harsh winter, with automated instruments transmitting data via the Iridium satellite constellation. Power is provided by specialized generators, and all operations adhere to strict environmental protocols enforced by the Committee for Environmental Protection.

Significance and future plans

The station has established China as a leading nation in Antarctic interior research, enhancing its role within the Scientific Committee on Antarctic Research. Its astronomical site testing has proven the location to be superior to even the Dome Fuji station. Future plans, under programs like the Polar Silk Road, may involve the construction of a permanent, year-round facility to support a proposed large optical-infrared telescope. This would significantly advance global efforts in fields like cosmology and solar system observation, cementing the station's status as a cornerstone of extreme-environment science.
