Abstract: | The net influx of the circumpolar water on the western (approximately along 10°E) and eastern (approximately 115°E) boundaries
of the Indian Ocean, adopting the method of Montgomery and Stroup is computed on bivariate distribution of potential thermosteric
anomaly and salinity to identify the characteristics of the flux. The zonal flux at both the boundaries indicates an alternate
strong easterly and westerly flow between 36°S and 45°S, south of which the flow is mainly easterly but weak up to 56°S. At
the western boundary the easterly flow is 146 Sv and westerly is 98.07 Sv, while at the eastern boundary (115°E) the corresponding
fluxes are 123.46 Sv and 27.20 Sv respectively, indicating a net outflux of 48.33 Sv. This water should have been accounted
by the melting of ice and influx of the Equatorial Pacific Ocean Water. |
