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.

IGY时期，俄罗斯科学院在东西伯利亚的Suntar-Khayata山脉进行了广泛的冰川学研究，那里大约有180条冰川被编号。 IGY之后，除了航空照片或卫星观测外，没有对该地区进行任何观测。 50年后，我们将冰川和气象观测作为IPY的一项活动。2004-2005年，在Suntar-Khayata Range 31号冰川周围（与50年前的站点相同的地方）和Oimiyakon地区进行了气象观测。奥米亚康年最低气温为-59℃（海拔约680米），而31号冰川（海拔约2050米）年最低气温为-45℃，表明该地区存在强烈的逆温现象。 2006-2007年，在马加丹和奥米亚康之间进行了气象观测。 2007年内陆地区最低气温低于-50℃，奥米亚康为-59.7℃，沿海地区较高，马加丹为-23.2℃。小冰期至1970年代，北部地块冰川退缩50-150m，南部地块冰川退缩100-200m。这种差异源于鄂霍次克海地区与北极地区气候变化的差异。
