Figure 34. Location map for Prudhoe Bay region, showing road network and sample sites A through E. 



contains observations by the scientists who visited the region. In addition, the Tundra Biome Pro- 

 gram Review Committee visited the region. Its comments on the Prudhoe Bay operations and poten- 

 tial for future research are contained in the report which was distributed in September 1970. 



Climate 



Recent climatic data from Prudhoe Bay are now available in conjunction with Federal Aviation 

 Agency observations. The nearest permanent long-term climatological station is at Barter Island. 

 For this report, a simple comparison of Prudhoe Bay and Barrow air temperatures for the 1970 growing 

 season will suffice (Table XXXI). 



Temperatures at Barrow and Prudhoe rose above freezing on 27 May. The May temperatures at 

 both locations were quite similar. By June the trend for warmer than Barrow temperatures at Prudhoe 

 was obvious: the maximum air temperature at Prudhoe for that month was 18.3"C and that at Barrow 

 was 12.8°C. July was the warmest month at both locations, with Prudhoe temperatures 2°C or more 

 warmer than those at Barrow. Maximum summer temperatures were 21.1°C at Prudhoe and I7.8°C at 

 Barrow. August was decidedly warmer at Prudhoe than at Barrow. This, plus the fact that Barrow
