A synoptic snapshot in this study is made for the East Cape Eddy (ECE) based on the World Ocean Circulation Experiment (WOCE) P14C Hydrographic Section and Shipboard ADCP velocity vector data collected in September 1992. The ECE is an anticyclonic eddy, barotropically structured and centered at 33.64“S and 176.2TE, with warm and salinous- cored subsurface water. The radius of the eddy is of the order O (110 km) and the maximum circumferential velocity is O (40cms-1); as a result, the relative vorticity is estimated to be O (7x 10-6s-1). Due to the existence of the ECE, the mixed layer north of New Zealand becomes deeper, reaching a depth of 300 m in the austral winter. The ECE plays an important role in the formation and distribution of the Subtropical Mode Water (STMW) over a considerable area in the South Pacific.
