Between 1962 and 1970, about 135,000 hours of continuous records of near-surface ground temperature, surface ground temperature, and near-ground air temperatures were collected by thermal recording stations located at Nussbaum Riegel in Taylor Valley and near McMurdo Sound. The closing of these unmanned stations marked the end of the patterned-ground projects field study. Preliminary analysis of selected records indicates a large number of freeze-thaw cycles per year, in the surface soil. The effects of cloud, shadows, and snowcover on the soil temperature are remarkably evident.
