. ‘By this process it will be possible for us to derive the sea surface profiles 
produced by both offshore and longshore wind stresses. Actual sea level 
consists of the sum of these two. Tables v and VI give the results for both 
of these stress components ee tively. These are also illustrated by 
Figures 4 and 5. | 
Looking at Tables III and IV and the two diagrams (Figures 4 and 5) we 
at once notice that there is practically no change in sea level outside the .

the sea level rises nearly linearly age wé are removed away from the coast 
until we arrive at the end of the wind zone. This tendency is common to the 
cases h/D, = 1/16, 1/8, 1/4 but some irregularities occur when rd, =1/2. 
Tt win be hard to know if those irregularities really exist or if they are 
actually due to some incompleteness of the procedure of numerical integration. 
Perhaps the latter explanation holds batters In any event, the general 
tendency is that the sea surface outside the wind zone suffers no appreciable 
-lewel change. Now since the sea is supposed to extend infinitely, the change 
of the sea level in a finite area will not affect the level in an infinitely
