The results of observations over two meridional sections in the equatorial zone of the Indian Ocean in February 2017 during cruise 42 of the R/V “Akademik Boris Petrov” are analyzed. It is shown that at 65° E, the Tareev equatorial undercurrent is observed with a core at a depth of 50 m slightly to the south of the equator. At 68° E, the current is deepened and disintegrates into separate jets covering a distance of more than 700 km.



The R/V “Akademik Boris Petrov” expedition was supported by the Federal Agency for Scientific Organizations of Russia and with the assistance of the Agency staff. The analysis was supported by the Russian Science Foundation, grant 14-50-00095. We thank all the participants of this expedition, including the scientific team and crew of the ship, who facilitated the scientific observations.
