HISTORY AND FACILITIES
The station was established in 2001 by the Siberian Branch of the Russian Academy of Sciences and the Vrije University of Amsterdam (Netherlands) with financial support from the government of Netherlands and with permission and help of the Ministry for Nature Protection of the Republic of Sakha (Yakutia). For accommodation, there is one 4×8 m large living house with four beds and firewood and kerosene heating. Additional tent accommodation for 4-6 peoples is possible during summer time. Kitchen is available. In addition, a big house for 10-12 peoples and a sauna can be rented from the Kytalyk Wildlife Reserve. There are two 5 m high observational towers for meteorological and flux measurements. Basic instruments are available at the station. Electrical power supply is provided by solar power and wind generator (12 V DC) and portable electrical generators (220 V Arctic Council, a high level forum of Arctic nations (Canada, Finland, Denmark/Greenland, Iceland, Norway, Russia, Sweden and the United States).

GENERAL RESEARCH AND DATABASES
The interdisciplinary research at the Chokurdakh Scientific Tundra station mainly focus on studies of the environmental conditions and the role of permafrost ecosystems in According to the United Nations Framework Convention on Climate Change, climate change is change in the climate of the whole Earth or a region of the Earth that is believed... More. This includes the interaction between the atmosphere, the biosphere, the hydrosphere, and the cryolithosphere with respect to biodiversity and global environmental change. Short-term monitoring data exists for different aspects of human activity. Data is available at the web-sites of PIN-MATRA and TCOS-Siberia projects.
The Chokurdakh Scientific Station is situated in the Kytalyk Wildlife Reserve of the World Wide Fund for Nature, which is dedicated to the preservation of the white crane (Grus leucogeranus). Human activity is restricted to fishing and reindeer herding.
The Chokurdakh Scientific Tundra Station can be reached from Chokurdakh settlement which is 3.5 hours by airplane from Yakutsk. From June to September, the transport to the station is possible by boat (2 hours from Chokurdakh along Berelekh River). In winter-time (November-April), transport takes place by snowmobile/sledge (2 hours from Chokurdakh).
