temperatures in a standard shelter were obtained 
by the authors in 1974. Gravel temperatures 
within a centimeter of the bare surface were 
recorded between 19 July and 3 September 
1974 on pad F. During this period the mean air 
temperature was 7.0°C, and the mean surface 
temperature of gravel was 9.2° C. Regression of 
daily average surface and air temperatures yield- 
ed the equation Y = 3.60 + 0.785X where Y is 
the average daily surface temperature and X is 
the average daily air temperature. The correla- 
tion coefficient (r) for this relationship is 0.90. 
Based on this analysis, an air-gravel surface 
temperature relationship is defined. The regres- 
sion equation can be applied to Prudhoe summer 
air temperature data as input to thawing and 
freezing computations and modeling. 
Conclusions 
It is apparent that the area adjacent to the 
road net at Prudhoe can be characterized as an

inland coastal climate and is significantly differ- 
ent than the immediate coastal climate as char- 
acterized by Barrow, Barter Island, and the 
summer temperature record at Point McIntyre. 
The shift to a true continental temperature 
regime occurs only a few kilometers inland of 
the coastline during the summer, although the 
winter ice cover off the coast reduces tempera- 
ture differences during the freezing season and 
provides a near-continental temperature pattern 
even to the coastal stations.
