Estimates of water flux and storage in organic-covered, permafrost terrains require an understanding of the factors controlling soil thaw. Field studies conducted in southern Yukon Territory, Canada, showed that ground freezing and thawing commenced at temperatures between -0.14 and -0.24 degree C. A temperature drop below -0.6 degree C had little effect on unfrozen moisture content. Unfrozen moisture storage shifted abruptly between a winter period value of ca. 50 mm and a summer period value of ca. 100 mm, although soil temperatures remained close to the freezing point for extended periods. The organic soil transmitted water laterally early in the thaw period while the water table still remained in the organic...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
