Coral terraces at Huon peninsula, Papua New Guinea, are well-known key areas for the study of late Quaternary sea level fluctuations and tectonic movement. Our new international research group, composed of 14 members from five countries who have different specialties, has succeeded in establishing new sea level curves, tectonic process for uplift, and erosional process for terrace denudation, based on data newly obtained by field work in 1992 and 1993. These results have contributed considerably to the understanding of Quaternary history and environmental changes. This paper describes the purpose, study method, organization, new results and presentation of the results for fundamental information on the planning of future, successful international and interdisciplinary joint research.
