During 1970/ the maximum observed bottom temperatures in the warm 

 Slope water zone ranged from slightly >12.0C to nearly 15. OC. 

 This range is similar to that observed in 1974/ but cooler than 

 in 19/5/ when unusually warv, as well as moderately colder/ 

 temperatures occurrea. The observed inter- section of the slope 

 front with the bottom was generally at depths shallower than 

 IJC m/ except in April when the depth was nearly 120 m/ during 

 the time when the Shelf 4ater was at its annual minimum 

 temperature in depths >7C m as described -above.
