Time Series of Seasonally Frozen Ground Depth in the Russian Arctic, 1930-1990

Project:

ARCSS

Summary

This data set consists of seasonally frozen ground depth measurements based on soil temperatures in the Russian Arctic. Seasonal freezing and thawing processes in cold regions play a major role in ecosystem diversity, productivity, and the Arctic hydrological system. Long-term changes in seasonal freeze and thaw depths are also important indicators of climate change. Investigators collected data from 211 ground-based stations. The record extends from 1930 to 1990 and includes seasonal freeze depths derived from soil temperature data that are averaged yearly. Data are in tab-delimited ASCII text format.
