bearing Lines/', and better correlation exists from one bearinp 

 Line to the next. The 2 1/2 month intrusion which showed up on 

 the Casco Bay 120 bearing Line from July to mid-September was 

 caused by a large meander and warm core eddy formation which was 

 also associated with a large increase in the area of Slope Water. 

 Although the Casco Bay 140 Line does not show strong evidence of 

 this/ the other two lines show definite shoreward displacements. 



The Casco Bay 120 bearing Line shows the greatest fluctuation of 

 the three/ with the Casco Bay 140 line showing large fluctuations 

 only in the first three months of the year/ and the Casco Pay 160 

 line showing only minor fluctuations during the whole year.
