remained relatively constant over the spring, summer, 

 and fall seasons for both the NAP and SAP study areas 

 in 1986 which led Brueggeman et al. 1 to conclude that 

 there was no indication that sea otters were redis- 

 tributed from the northern to the southern Peninsula 

 during the winter months. Instead, Brueggeman et al. 1 



attributed the differences in the survey results between 

 1982-83 and 1986 to the viewing conditions and wind 

 speed in which Cimberg et al. 2 conducted their March 

 and October surveys. Although both the 1976 and 1983 

 estimates were adjusted for sea otters missed by ob- 

 servers, the 1986 estimates were not. Evans et al. 4
