  abstract = {{A}rgo float data in the tropical {P}acific {O}cean during {J}anuary 2003 {A}ugust 2011 are analyzed to obtain {L}agrangian subsurface velocities at their parking depths. {M}aps of mean zonal velocities at 1000 and 1500 m are presented. {A}t both depths, a series of alternating westward and eastward zonal jets with a meridional scale of 1.5 degrees is seen at the basin scale from 10 degrees {S} to 10 degrees {N}. {T}hese alternating jets, with mean speeds about 5 cm s(-1), are clearly present in the western and central parts of the basin but weaken and disappear approaching the eastern coast. {T}hey are stronger in the {S}outhern {H}emisphere. {A}long the equator at both 1000 and 1500 m, a westward jet is seen. {T}he jets closer to the equator are remarkably zonally coherent across the basin, but the jets farther poleward appear broken in several segments. {I}n the western half of the basin, the 1000-m zonal jets appear to slant slightly poleward from east to west. {A}t the western boundary in the south (east of {S}olomon {I}slands and {P}apua {N}ew {G}uinea), the alternating jets appear to connect in narrow boundary currents. {S}easonal zonal velocity anomalies at 1000 and 1500 m are observed to propagate westward across the basin; they are consistent with annual vertically propagating {R}ossby waves superimposed on the mean zonal jets. {T}heir meridional structure suggests that more than one meridional mode is present.},
