This data set contains soil temperature data from three deep boreholes in the Ob River valley in Russia. Boreholes were drilled in 1967 (VK-1615), 1977 (ZS-124), and 1980 (ZS-124a) in discontinuous permafrost of approximately 70 m depth. Borehole VK-1615 was sampled to a depth of 100 m between 1971 and 2002, ZS-124 was sampled monthly to a depth of 13 m between 1978 and 1980, and ZS-124a was sampled monthly to a depth of 33.7 m between 1980 and 2002.
