In 1963, the source of the Equatorial Undercurrent appeared to be near 38°W. This undercurrent was an equatorial extension of a narrow saline current setting east-southeast at the surface near 2 °N 42 °W. Near 380°W, a retroverse branch of the Guiana Current also joined the Equatorial Undercurrent. Surface flow was easterly along all of the east-southeast current and the undercurrent observed. The subsurface-velocity maximum of the undercurrent was higher at 35°W than at 38°W.
