Figure 11.2 Mass transport in the eastern Pacific calculated from Sverdrupís theory using observed winds with 11.9 and 11.11 (solid lines) and pressure calculated from hydrographic data from ships with 11.4 (dots). Transport is in tons per second through a section one meter wide extending from the sea surface to a depth of one kilometer. Note the difference in scale between My and Mx. From Reid (1948).
