This project constitutes the lead and coordination effort for a study involving four US institutions, and institutions from Australia and France. A joint field program will be carried out to study the water mass distributions, current structures and transport of the low-latitude western boundary currents in the western Equatorial Pacific. Focus will be on the confluence of northern and southern hemisphere waters, which arrive at the entrance to the Indonesian Seas via the South Equatorial Current, the New Guinea Coastal Undercurrent, and the Mindanao Current. Water mass tracers and direct current measurements will be employed. Lukas and Firing will carry out hydrographic, moored current meter, and shipboard Acoustic Doppler Current Profiler (ADCP) measurements, while coordinating the work of Fine (Miami) and Gammon (UW), who propose, via subcontracts, to carry out tracer studies (freons and tritium/helium). The hydrography will be done by the Scripps data acquisition facility, under a separate award. Richardson (WHOI) will deploy an array of surface drifters, to directly observe surface flows in the region. This experiment is a major process study contributing to the objectives of the US TOGA (Tropical Ocean and Global Atmosphere) Program.

该项目是一项研究的牵头和协调工作，涉及四个美国机构，以及来自澳大利亚和法国的机构。联合开展实地考察项目，研究赤道西太平洋低纬度西边界流的水团分布、流结构和输运。重点将放在北半球和南半球水域的汇合处，这些水域通过南赤道流、新几内亚沿海暗流和棉兰老流到达印度尼西亚海的入口。将采用水团示踪剂和直流电测量。Lukas和Firing将进行水文测量、系泊海流计和船载声学多普勒海流仪（ADCP）测量，同时协调Fine （Miami）和Gammon （UW）的工作，后者通过分包合同提议进行示踪剂研究（氟利昂和氚/氦）。水文测量将由Scripps数据采集设施完成，并获得单独的合同。Richardson （WHOI）将部署一系列地面漂移仪，直接观测该地区的地面流动。这个实验是一个主要的过程研究，有助于实现美国TOGA（热带海洋和全球大气）计划的目标。
