Uda— What can you say of the influence or stratification by frontal trans- 

 port or movement of cold water invading as in the case where 

 Oyashio and Kuroshio come together? 



TuLLY— This is a technique for marking or examining the structure. 

 Using the technique emphasizes the limits of such invasion.

 all over the world.
