We organized first international symposium on mountain and arid land permafrost in 2001 (see report on FG25). 22 – 26 August, 2011 we had organized the second international symposium on mountain and arid land permafrost in Ulaanbaatar, MONGOLIA. 25 scientists from Norway, Japan, Romania, USA, China, Russia and Mongolia have participated at the Second international symposium on mountain and arid land permafrost. 14 oral presentations and 7 poster presentations including 4 welcome speeches were presented during the 2 days in the conference hall of the Mongolian Academy of Sciences. A roundtable discussion summarized the symposium, and resulted in three recommendations approved during the closing session (see the symposium report).

 

 


Attendees of the second international symposium on mountain and arid land permafrost in Ulaanbaatar, Mongolia, 22 – 26 August, 2011.

Especially, the Mongolian permafrost and ecological network was recognized as critical for understanding the dynamics of permafrost on a changing planet. At present there are 86 CALM and GTN-P boreholes in Mongolia. All the boreholes have been instrumented to prevent from air temperature convection in them and to protect them against damage by passing people. Some of boreholes have temperature measurements in 1968 – 1987 by Sharkhuu. Initial results of the long-term permafrost monitoring show that the average increase in ALT is 0.5-2.0 cm/year and in MAGT is 0.01-0.03 oC/year  under the influence of recent climate warming in Mongolia. Nowadays borehole drillings and field measurements were sponsored by Geography Institute of MAS, Ministry of Nature, Environment and Tourism of Mongolia, Hokkaido University and JAMSTEC, Japan.

Next year (2012) we are planning to drill additional boreholes in Mongolia by supports of Ministry of Nature, Environment and Tourism of Mongolia. As Mongolia lies on southern edge of Siberian permafrost region there are possibility relict permafrost in Mongolia. Therefore we are expecting to drill at relict permafrost within 2012 drilling operation.

According to geographical location Mongolia has a specific weather condition with a cold long winter and less snow cover. This specific weather leads to form the pereletok in some cold year and there is deep seasonal frozen ground until to 5-6 m in some areas with coarse materials. Using this weather specific of Mongolia our senior scientist Dr Lonjid had constructed ice storages in some regions of Mongolia in 1960s – 1980s and in 2010 – 2011 new reconstructed ice storages have been constructed in some towns of Mongolia. Oldest ice storage, constructed in 1968, has a good condition until today.
