Photo: Ko van HuistedenThe Chokurdakh scientific tundra station is situated in the Kytalyk wildlife reserve, located on the left bank of the Elon (Berelekh) River in North-Eastern Yakutia, Republic of Sakha in Yakutia in the Russian Federation. The field site is approximately 25 kilometer north of the Chokurdakh settlement and around 480 kilometer north of the Arctic Circle.

The research area consists of three different morphological units: the river floodplain, the river terrace with tundra vegetation and the high plateaus (1030 metres) underlain by continuous permafrost, with permafrost thickness over 300 metres.

The Kytalyk is a preservation area of white crane (sterkh, Grus leucogeranus) and most common human activities include fishing and reindeer breeding. An average temperature of the warmest month, which is July, in the area is 9.5 degrees Celsius and that of the coldest month, which is January, is -34.6 degrees Celsius.

Within PAGE21, following research will be conducted in Kytalyk:

  • CO2, CH4 fluxes using eddy covariance with two eddy covariance towers
  • N2O using flux chambers
  • Ecosystem exchange of latent heat, water vapor
  • Soil temperature and soil heat balance
  • Hydrology: precipitation, snow cover, water table and runoff
  • Detailed flux measurements on thaw ponds
  • Monitoring of active layer thickness
  • Monitoring of permafrost thaw activity along a thaw lake bank
