tions, and thus approximate what occurs in nature. 

 The geostrophic current information, while some of 

 the best available, nonetheless constrained the 

 spatiotemporal resolution of this model, and incor- 

 porating Ekman transport required several assump- 

 tions. Further, there can be considerable interannual 

 variability in the modeled region (Mooers and Robin- 

 son 1984; Simpson et al. 1984), and presumably the 

 model is of "average" conditions and cannot be 



representative of any specific year; I felt that in- 

 cluding such variability (assuming adequate data 

 were available) would complicate the results without 

 significantly contributing to biological insight. An
