The observations on the equator reveal the existence of two mean westward cores of the Equatorial Intermediate Current below the Equatorial Undercurrent. In contrast to the 2002 moored observations at the same position the intraseasonal variability during the mooring period is dominated by zonal instead of meridional velocity fluctuations. specialized 33 7 NIL_9-NIL_12 2006 0094-8276 https://www.documentation.ird.fr/hor/PAR00000909 10.1029/2005GL025498 0094-8276 https://www.documentation.ird.fr/hor/PAR00000909 IRD - Base Horizon / Pleins textes 2006-08-10 2017-08-23 PAR00000909 fre
