The Arlindo Project was conceived to investigate the oceanography of the Indonesian seas in a joint oceanographic research endeavor of Indonesia and the United States. Inter-ocean transport within the Indonesian Seas plays a key role in the global thermohaline circulation, and is relevant to ENSO as it allows seepage of the western Pacifics warm pool water into the Indian Ocean, adjusting the volume of the warm pool. Mixing processes within the seas influence the circulation pattern. Arlindos goal is to resolve the circulation and water mass stratification within the Indonesian Seas in order to formulate a thorough description of the source, spreading patterns, inter-ocean transport and dominant mixing processes within the Indonesian Seas. The program is organized in 3 Phases I Arlindo Mixing, II Arlindo Circulation, and III Arlindo Monitoring. Phase I was carried out in 1993 and 1994, consisting of an extensive array of CTD, tracer and productivity stations within the interior seas of Indonesia. During Phase II moorings were deployed in key throughflow passages to measure currents, internal waves, mean water column temperature and sea funded principally by NSE, with a significant contribution from ONR under this award.
