Abstract
Observations over a 5-year period at a site at Ottawa showed that the ground temperature had significant Fourier components with period 1/2 and 2 years. The average annual ground temperature and amplitudes of the Fourier components of period 1 year and 1/2 year underwent non-periodic fluctuation decreased with depth, and its maximum occured later in time. There was evidence of a gradual increase in average annual ground temperature amounting to about 0.2 C degree over the 5-year period at the 610-cm depth. The significance of such small temperature changes in areas where the ground temperature is close to 0 C degree is pointed out.
