| Subsurface float measurements at 800 m depth carried out from 1994 to 2003 in the Brazil Basin are used to characterise the equatorward Intermediate Western Boundary Current (IWBC) and its connections to the ocean interior. Transversally, the boundary flow is less than 100 km wide, and most intense at 10-20 km from the 800 m isobath. Its average velocities range from similar to 0.1 ms(-1) to 0.3 ms(-1) depending on latitude, with individual daily values as high as 0.7 ms(-1). The flow meridional extent exhibits 3 contrasted domains: (i) from 27 degrees S to the Vitoria-Trindade Ridge at 20 degrees 30'S, the boundary flow intensifies northward along a relatively smooth topography. A counter current adjacent to it on its seaward side feeds it with... |
