Spasskaya Pad (Yakutsk)
Primary CryoNet Station Information

Spasskaya Pad (Yakutsk) Observatory is located on the left side of the central part of the Lena river in Eastern Siberia at an elevation of 220 m a.s.l. approximately 20 km north of the city of Yakutsk. The site, located in a region of continuous permafrost is referred to as the Spasskaya Pad experimental forest of the Institute of Biological Problems in the Cryolithozone, Siberian Brunch of Russian Academy of Sciences (SB RAS). There are two observational towers (32 m in larch forest and 24 m in pine forest) with a wide range of micrometeorological devices and eddy-covariance systems. Three 20 m high crown-access towers with full access to any tree level in larch forest are available for botanical, morphological, and ecophysiological studies.

The Spasskaya Pad Scientific Forest Station was founded in 1952 by the Krasnoyarsk Forest Institute (SB RAS). In 1992, the station was transferred to IBPC SB RAS. It consists of several new or recently renovated buildings. The station is fully equipped with year-round accommodation facilities, heating, electricity, portable electrical generators, radiotelephone, computer, printer, scanner, etc. A laboratory is available, equipped with some basic tool-boxes and instruments, drying ovens, refrigerators, scales, etc. The station can accommodate up to 30 persons during the summer.

Inter-disciplinary research is conducted at the station with focus on understanding fundamental characteristics, processes, and their spatio-temporal variations of the atmosphere, the biosphere, the hydrosphere, and the cryolithosphere in boreal forest with underlying continuous permafrost. Ecosystem dynamics and biodiversity are also studied to assess the impact of global environmental change. Research also includes short term monitoring of different aspects of human activity.
