Abstract	The Vessel-Mounted Acoustic Doppler Current Profiler (VM-ADCP) measured currents in the upper 200 m along the cruise track covering the southeastern Arabian Sea and the Eastern Equatorial Indian Ocean during northern winter monsoon (10-31 December) of 2000 are presented. In the study area, the westward flowing North Equatorial Current is identified at 4 degrees N southeast of Sri Lanka and its northwestward flow into the southeastern Arabian Sea over a wider zonal belt 4 degrees N-7 degrees N west of 80 degrees E. It attains higher speed (more than 50 cm/s) outside the Gulf of Mannar augmented by the strong northeasterly winds blowing over the Gulf. With the eastward flow north of 7 degrees N towards the Gulf, a clockwise eddy (early stage of the Lakshadweep High) is formed off south-southwest coast of India due to local wind forcing. A strong (more than 50 cm/s) eastward flowing North Equatorial Counter Current (NECC) is developed in the zonal belt 0-3 degrees N due to prevalence of the equatorial west wind forcing through December and retroflection of NEC. The transport of the NECC in the upper 100 m varies from 4x10@u6@@ m@u3@@ /s at 83 degrees E to 7x10@u6@@ m@u3@@ /s at 93 degrees E. The data details the structure of the South Equatorial Counter Current south of the equator from 83 degrees E to 93 degrees E.
