From June 1982 to June 1983, the Board on Science and Technology for International Development sponsored a United States-Indonesia Marine Science Exchange Program which provided support for visits by seven U.S. marine scientists to Indonesia. These scientists presented lectures on topics of interest to Indonesians, gained a better insight into the scientific phenomena of Indonesian waters, and discussed projects that could aid the development of marine science in Indonesia. This report summarizes the lectures presented by the visiting scientists. The first part describes the importance of marine science to Indonesia and the second provides recommendations for technical assistance, collaborative research, and training programs to assist the development of marine science in that country. Appended are an introduction to marine environments in Indonesia and the trip reports of exchange program participants. (Author abstract, modified).
