Ground Temperatures from Deep Boreholes in the Ob River Valley, Russia (VK-1615 and ZS-124/124a), Version 1

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.

Detailed Data Description

This data set includes soil temperature data from 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 to a depth of 13 m between 1978 and 1980, and ZS-124a was sampled to a depth of 33.7 m between 1980 and 2002..

Both boreholes are in a high glacial-marine plain, dominated by tundra, with loam, loamy sand, and gravel soil.

Peat: 0 - 0.9 m
Loam and loamy sand: 0.9 - 31.2 m 
Gravel and sand: 11.5 - 13.3 m

The boreholes are 20 km from the nearest road, 100 m from a small river, and 9 m above the river.The nearest climate station (40 km) is located at Vorkuta (67° 20' N, 64° 01' E).

The VK-1615 borehole had low to medium ice content, and the ZS-124/124a boreholes had low to high ice content. Borehole VK-1615 is at 154.7 m elevation, and boreholes ZS-124/124a are at 205.4 m elevation.

The mean, as of 2002, annual ground temperature at a depth of zero annual amplitude was -0.34°C (VK-1615 at 15 m depth) and -1.35°C (ZS 124/124a at 11 m depth).

Format

Data files are formatted as tab-delimited ASCII text, with one file per year per borehole. Each yearly file provides soil temperature data for up to five days per month at various depth intervals. Missing data are recorded as -999. Quality files are ASCII text and provide QC notes for years/files as recorded.
