INTRODUCTION 



Changes in physical and chemical properties of the ocean 

 (currents/' tempe ratu r er nutrients/' etc.) and the associated 

 modulation of bioloc^ical processes directly or indirectly affect 

 not only long-term yields and annual abundances of fish stocks/ 

 but also their distribution and availability. Fishery Oceano- 

 graphy/ r^s a subproqram of i^iARMAP^ includes the analysis of 

 physical/ chemical/ and biological oceanographic data collected 

 during ^'ARMAP and other NMF? surveys and from oceanog raphi c and 

 me t eorol cgi c aL operational and research activities of other 

 a'lencies. Fishery Oceanography providea much of the information 

 incorporated into Ocean Variability in the UiS. Fishery CoDser-
