FIGURE 20. The 363,000 square miles of the Hawaiian areo have 

 been shrunk to the size of a large pool toble in a three-dimensional 

 scale model at the Laboratory in Honolulu. By injecting dye into the 

 woter, scientists can study the development of eddies in the lee of 

 the islonds. Here is on ortist's rendering of one such experiment. 



showing the effects of a flow of water from the northwest (typical 

 summer conditions). As the current moves Ground the islands, large 

 persistent eddies ore formed in their wake. The experiments shown 

 here represent obout a month of steady northeostcrly flow.
