Abstract Detection of changes in the hydrological cycles of permafrost regions is a critical issue in hydrology. Better understanding of groundwater dynamics in permafrost regions is needed to assess the vulnerability of the cryolithic water environment to changing climate.

In order to determine the residence time of permafrost groundwater in eastern Siberia, transient tracers including tritium ( 3 H), chlorofluorocarbons (CFCs), and sulfur hexafluoride (SF 6 ) were used to analyze a mixture of supra-permafrost and intra-permafrost groundwater in the middle of the Lena River basin.

Comparisons of apparent groundwater ages estimated from different tracers imply that 3 H and CFC-12 are the most applicable to groundwater vulnerability assessments in this region. Because the apparent age is a mixture of those from supra-permafrost and intra-permafrost groundwater, further analysis would be required to assess the contribution ratio of the two types of groundwater.

Figure 1. Map showing locations of springs on the Bestyakh terrace, middle of the Lena River basin, eastern Siberia. Abstract Detection of changes in the hydrological cycles of permafrost regions is a critical issue in hydrology. Better understanding of groundwater dynamics in permafrost regions is needed to assess the vulnerability of the cryolithic water environment to changing climate. However, little is known about the age of groundwater in the Siberian Arctic region. In order to determine the residence time of permafrost groundwater in eastern Siberia, transient tracers including tritium ( 3 H), chlorofluorocarbons (CFCs), and sulfur hexafluoride (SF 6 ) were used to analyze a mixture of supra-permafrost and intra-permafrost groundwater in the middle of the Lena River basin.
