Abstract

Hydrographic data collected aboard R. V. Anton Bruun along 65°E between 18°N and 42°S from 17 May to 4 July 1964 are used to investigate water characteristics and currentstructure in the upper 500 m in the Indian Ocean. The water characteristics indicate theoccurrence of three main water masses, viz., warm, saltier, low-oxyty and nutrient-rich Arabian Sea Surface Water, relatively fresh and high-oxyty Equatorial Indian Ocean Water, and more saline, high-oxyty and nutrient-poor Tropical Water of the South Indian Ocean.The recently discovered South Equatorial Countercurrent and Subtropical Countercurrent (renamed Tropical Countercurrent, at the suggestion of Dr. R. B. MONTGOMERY) are observedin the current structure at 13°S and 22°-26°S respectively, and these could also be identifiedon the vertical sections of temperature, thermosteric anomaly and salinity. Contrary to theexisting concept, the North Equatorial Current continues to be present even after the onsetof the southwest monsoon. The Equatorial Undercurrent could not be traced in the IndianOcean during this period.
