514 EIGHTH PACIFIC SCIENCE CONGRESS 



Discussion 

 Barnes— Any evidence of any pattern of circulation below the sill? 

 Emery— None within individual basins. Most upwellings occur on the 



basin along the continental slope. 

 Barnes -Any tilt along the slope? 



Emery— No. Only indications of seiches within the basin. 

 Xmery (in answer to question by Uda)— In one of the deep basins there 



was a distinct rise of actual temperature with depth. 

 Dietz— Any indications of the effect of sediments on the slope? 

 Emery— Yes. But we have no information on channels running down 



the slope. 



13. "An Oceanographic Model of Puget Sound" by Chfford A. 

 JBarnes, John H. Lincoln, and Maurice Rattray, Jr., University of Wash- 

 ington, Seattle, Washington, U.S.A. Read by Dr. Barnes. With slides. 



Discussion 



TuLLY— Is it advisable to make a model on a bigger scale? 



Barnes— Yes, possibly on a space about four times as big. 



TuLLY— We have a corresponding model about 200 miles from that of 

 Dr. Barnes. With larger scale we get natural turbulence on rather 

 lower levels of flow, and a little more room to work in, as on sa- 

 linity gradients. One other trick would be the use of color photo- 

 graphy (with dyes). 



14. "Daily Seawater Observations on the Pacific Coast of Canada" 

 by H. J. Hollister, Pacific Oceanographic Group, Nanaimo, B.C., Ca- 

 nada. Read by J. P. Tully. 



Discussion 



Revelle— Is there really an association between daily sea water condi- 

 tions and the fisheries? 



Tully— Yes, as in the case of the tuna fisheries. 



Tully (answer to question by Dr. Bruun)— In the studies of correla- 

 tion with fisheries, there are actually more in Washington and Ca- 

 lifornia than in our own country. These studies were, in fact, 

 recommended by Dr. Helland Hansen in 1943. 



15. "A Study of Local Variability in Marine Sediments" by Richard 

 G. Bader, Department of Oceanography, University of Washington, 

 Seattle, Washington, U.S.A. 



16. "Secular Variation of the Annual Mean Sea Level along the 

 Japanese Coasts" by Masamori Miyazaki, Kobe Marine Observatory, 

 Japan. Read by title only. 



Session adjourned at 4:36 P.M.
