Figure 9. Sea-surface dynamic topography (dynamic meters) relative to 1000 decibars, 30 May-1 June 1968. Ar- 

 rows denote sea-surface dynamic heights at intervals of 0.02 dynamic meters. Staffs of arrows are drawn 

 perpendicular to imaginary line segments connecting adjacent stations; heads of arrows indicate direction 

 of geostrophic current. Nomograph for obtaining geostrophic speed when entering with distance between 

 0.02 dynamic-meter contours assumes latitude of 45°.
