Pacific Ocean Circulation — Hid AKA 
203 
z/D z = 1, z/D z = 1.5, z/D z — 2, and z/D z = 3. The most important of them is, of 
course, the surface circulation, and Figure 3a shows its pattern. The gross features of the 
current distribution on the surface thus do not seem to differ much from those given by 
Munk (1950) and by the author (1951) for the distribution of mass transport streamlines.
