Incursion of the Pacific Ocean Water into the Indian Ocean
G S Sharma A D Gouveia Shubha Satyendranath
Using the data collected during the International Indian Ocean Expedition, maps showing the distribution of depth, acceleration potential, salinity and oxyty were prepared for the northeast monsoon for the four potential thermosteric anomaly surfaces: 160, 120, 80 and 60 cl/t. Zonal components of current aong 84°E were computed from the geopotential dynamic heights. From such an analysis, it became clear that low-salinity water from the Pacific intrudes into the western Indian Ocean through the Banda and Timor seas in the upper layers above 100 cl/t surface, while the North Indian Ocean Water penetrates towards the Eastern Archipelago below 100 cl/t surface. The South Equatorial Countercurrent and the Tropical Countercurrent are well depicted on the vertical section of zonal components as well as on the distribution of acceleration potential.

The West India Coastal Current (WICC) flows southward (northward) during summer (winter). We examine the nature of circulation in the region of WICC during an inter-monsoon period using hydrographic data collected during March 6–21, 1994, and archived 1994 daily altimeter data. The hydrographic data did not show any organized northward or southward Cow, implying that the amplitudes of the Rossby and Kelvin waves that make the WICC were negligible. Instead, cyclonic and anticyclonic eddies, well recorded in altimeter data, dominated the circulation. Because eddies occur throughout the year, our analysis highlights the need to study their role in WICC all through the year.
