SYMPOSIUM ON GENERAL CIRCULATION IN THE PACIFIC 



Convener: Dr. Koji Hidaka, Geophysical Institute, Tokyo University, 



Tokyo, Japan. 

 Secretary: Mr. Alfonso R. Sebastian, Bureau of Fisheries, Manila. 



PROCEEDINGS 



Session started at 9:00 A.M. Dr. Hidaka remarked that although 

 the symposium would be about the general circulation of the Pacific, 

 some papers to be presented would touch on other aspects of physical 

 oceanography. He suggested a limited speaking time of 10 to 15 min- 

 utes for every one who would present a paper. He made an exception 

 in the case of Dr. Pettersson who had requested for longer time. 



Papers read and discussions that followed were: 



1. "Theoretical Studies on the General Circulation of the Pacific 

 Ocean" by Dr. Koji Hidaka, Tokyo University, Tokyo; Department of 

 Oceanography, Texas A. & M. College, College Station, Texas. Read 

 by Dr. Hidaka. With slides. 



Discussion 

 TuLLY— In your calculations do you come to a level of no motion? 

 Hidaka— Yes, at 10 D^. 

 Spilhaus— Do your calculations show the Equatorial Counter Current 



underneath the Equatorial Current? 

 Hidaka— We have not yet reached that in our studies. 

 Hidaka (in answer to question by Uda)— This theory assumes that the 



mixing coefficient is constant. 



2. "A Contribution to the Theory of Upwelling and Coastal Cur- 

 rents" by Dr. Koji Hidaka. Read by the author. With slides. 



Discussion 

 TuLLV— Is this theory for infinite depth? 

 Hidaka— Yes. For finite depth it becomes more complicated. 

 Spilhaus— Do your computations hold approximately, as long as the 



depth is 2D? 

 Hidaka— Yes. 



Schmidt— For what latitude were these computations made? 

 Hidaka— Latitude 30°.
