| Research Abstract |
In the period of IGY, Russian Academy has made glaciological researches extensively in Suntar-Khayata Range in Eastern Siberia, where about 180 glaciers were numbered. After the IGY, no observation was done in this area except aerial-photo or satellite observation. After 50 years, we made glaciological and meteorological observations as an activity of IPY.
In 2004-2005, meteorological observation was done around Glacier No. 31 in Suntar-Khayata Range (the same place as the station before 50 years,) and at Oimiyakon area. The minimum temperature in a year was -59C at Oimiyakon (about 680m a. s.l.), while it was -45C at Glacier No. 31 (about 2050m a. s.l.), which suggests there was strong temperature-inversion in this area.
In 2006-2007, meteorological observation was done between Magadan and Oimiyakon. The minimum temperature in 2007 was below -50C in inner region, -59.7C at Oimiyakon, while it was higher at coastal region, -23.2C at Magadan.
Glaciers retreated 50-150m in length in the Northern massif from Little Ice Age to 1970's, and 100-200m in the Southern massif. This difference would derive from the difference of climate change between Sea of Okhotsk area and Arctic area.
