  abstract = {{H}istorical ship drifts and geostrophic surface currents obtained from hydrographic data are compared in the {T}ropical {A}tlantic ocean. {T}he major components of the current system ({N}orth {E}quatorial {C}urrent, {N}orth {E}quatorial {C}ountercurrent, {S}outh {E}quatorial {C}urrent) are clearly depicted by the two data sets. {T}he main difference between the two fields is the weakness of the geostrophic currents except in the near-{E}quatorial band, where on the contrary, they are much larger than the ship drifts. {T}he amplitudes of the annual signals differ, but the phases are in rather good agreement. {T}he uncertainty concerning the ship drift data, and the limitation of the geostrophic assumption, can explain a part of the differences encountered in this study.
