  abstract = {{D}ynamic height was calculated from {XBT}s collected along several shipping routes in the western {I}ndian {O}cean. {I}n the northern hemisphere, low dynamic heights prevail during the {NE} monsoon and high dynamic heights during the {SW} monsoon inducing an alternating {S}omali {C}urrent. {I}n the southern hemisphere, at 7°-8° {S} a trough of low dynamic height occurs during the whole year. {EOF} analysis is used to document the variation of these features. {T}he geostrophic transports calculated for the {XBT} routes show spatially coherent patterns with strong seasonal variations. {I}n the {A}rabian {S}ea, an anticlockwise gyre develops during the {NE} monsoon alternating with a clockwise gyre during the {SW} monsoon. {B}etween 5°{N} and 5°{S}, the transport variations show eastward flow twice each year during the monsoon transitions, except on the western most route where the annual variations of the gyre in the {A}rabian {S}ea extend to the equator. {T}he mean transport of the {S}outh {E}quatorial {C}urrent increases regularly with longitude from east to west in all months. {I}t has small annual variations, and the phase of the annual maximum progresses consistently westward.
