摘要	Herein, the spatial characteristics of the Equatorial Undercurrent (EUC) in the region between Mindanao and New Guinea and the origins of the EUC and the North Equatorial Countercurrent (NECC) were investigated using a combination of high-resolution Argo hydrographic data and numerical modeling. The Mindanao Current (MC) results in the formation of a strong EUC-depth eastward current that splits into two branches near the Halmahera Eddy west of 132 degrees E, with one branch directly flowing eastward without experiencing the Halmahera Eddy rotation effect, and the other branch flowing southwestward and then turning northeastward. The EUC and NECC were difficult to distinguish between 132 degrees E and 136 degrees E, since the former combined with the latter to form a continuous equator-tilted current. At similar to 137 degrees E, the EUC axis started turning toward the equator, and an isolated EUC core was observed at 143 degrees E and similar to 200-m depth. The Pacific EUC was shown to originate at similar to 130 degrees E, where it featured an isolated current core with a maximum velocity of 5-10cm/s at similar to 1 degrees N and 200- to 400-m depth. The EUC and NECC in the western tropical Pacific were found to have the same water sources, namely, the MC and the New Guinea Coastal Undercurrent, with the shallow parts (centered at similar to 100-m depth) of MC and New Guinea Coastal Undercurrent finally reaching the NECC and their deeper parts (centered at similar to 200-m depth) finally reaching the EUC.
