VII. Discussion of the methods and results, and additional tests of 



the theory. 



The assumptions (page 257) on which the computation of the sur- 

 face temperatures were based are not in accord with the actual con- 

 ditions, first, because the direction of the coast is not north and south 

 except at station (4), second, because the flow is not normal to the 

 coast as assumed, but, as will be shown, is directed toward the south 

 west at angles varying from (0) to (90) with the coast. To justify 

 the method used in computing the temperatures, and to explain various 

 peculiarities of temperature distribution, a more detailed consideration 

 of the distribution and magnitude of the currents deduced from Ekman's 

 theory will be required. But the necessary mathematics for such a 

 quantitative study can be avoided and a qualitative explanation of 

 some of the results can be worked out by assuming an ideal set of 

 conditions and then estimating the change in the result due to such 

 a modification of these assumed conditions as will secure an agreement 

 with the actual circumstances observed at the different regions. 



If a steady wind uniform in direction and velocity blows parallel 

 to a long straight coast, and the depth of the water is constant and 



*) The sign ( ) means that the component (V w ) is directed to the north, in 

 all other cases it is directed to the south.
