station data. 



Groundfish surveys were conducted princi- 

 pally during the fall months in an effort to esti- 

 mate the strength of new year classes of had- 

 dock, but some surveys were made at other 

 seasons of the year. There was considerable 

 yearly variation between cruise dates during any 



one season. In order to eliminate the effects of 

 short-term shifts in distribution, only cruises 

 spanning approximately similar time periods 

 were used in comparing yearly distribution pat- 

 terns. The dates and trawl station locations of 

 the cruises considered in this paper are shown 

 in Figures 3 and 4.
