Time Series of Seasonally Frozen Ground Depth in the Russian
Arctic, 1930-1990 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 and are available via FTP. The following example
shows how to cite the use of this data set in a publication. For
