B2: How does the Agulhas Current interact with the anticyclonic gyre east of Madagascar?B3: Where and how are water masses (mode waters) formed in the Indian Ocean?B4: What is the origin of the water transported by the Leuwin Current off westernAustralia? (See e.g., GODFREY and RIDGWAY, 1985.)B5: The circulation in the Subantarctic region is only known qualitatively. The heatexchange between the Indian Ocean and the Circumpolar Current system has apparently neverbeen assessed by physical methods.B6: Figure 4 illustrates the existing uncertainties in our knowledge about deep meridionalcurrents in the Indian Ocean.REGIONAL AND INTERNATIONAL STUDIESAll the research problems listed above do affect also various current or planned internationalprograms such as the Tropical Ocean and Global Atmosphere (TOGA) project, the World OceanCirculation Experiment (WOCE) and the International GeospherelBiosphere Program (IGBP). Assuch they are of some concern to all the participating countries and to the global scientific community.Regional studies within the framework of these international programs should provide scientists fromthe Indian Ocean littoral states with opportunities for cooperation and international support.REFERENCESDE RUIJTER, W.P.M. and BOUDRA, D.
