Description
Summary:The data from the Southern Ocean observations of World Ocean Circulation Experiment (WOCE) are used for analysis and illustration of the features and spatial distributions of Circumpolar Deep Water (CDW) in the southern Indian Ocean. It is learnt from the comparison among the vertical distributions of temperature/salinity/oxygen along the 30°E, 90°E and 145°E sections respectively that some different features of CDW and the fronts can be found at those longitudes, and those differences can be attributed to the zonal transoceanic flow and the merizonal movement in the Circumpolar Deep Water. In fact, the zonal transoceanic flow is the main dynamic factor for the water exchange between the Pacific Ocean and the Indian Ocean or between the Atlantic Ocean and the Indian Ocean, and for the effects on the spatial distributions of the physical properties in CDW.
