ABSTRACT 



A monthly mean sea current was calculated for the west coast of the United 

 States and the Hawaiian Islands area on a spatial grid of 1° by 1°. These mean 

 geostrophic velocities were computer generated from dynamic height data 

 obtained from the National Oceanographic Data Center. A method employing 

 two-dimensional spline fits of spatially and temporally random hydrographic 

 data was developed to determine the monthly averaged geostrophic currents.
