Estimates of equatorial upwelling between 140 deg and 110 deg W during 1984

The equation of continuity is used to estimate profiles of vertical velocity between 25 and 120 m from moored current measurements in arrays nested within the triangle with vertices located at 1 deg 30 arcmins S, 140 deg W and along the equator at 140 deg and 110 deg W during December 1983 through March 1984 and May-September 1984. All directions of the 4- to 5-month mean values were upward. The ensemble averaged mean vertical velocity was 0.000022 m/s. Upwelling speeds decreased eastward.
