  abstract = {{E}xpendable bathythermograph ({XBT}) data and the climatological temperature/salinity relationship were used to calculate the mean annual cycle of dynamic height and geostrophic transport of major currents relative to 400 db along five shipping tracks covering a large part of the tropical {P}acific {O}cean. {T}he data were selected in bands centered on the most frequently repeated {XBT} tracklines for the period 1967-1988. {L}ong-term bimonthly mean temperature was calculated in 1° latitude bins along the tracks. {T}he transport function (vertically integrated dynamic height) was then calculated using the mean temperature/salinity relationship. {T}he mean annual cycle of transport of the {N}orth {E}quatorial {C}urrent ({NEC}), the {N}orth {E}quatorial {C}ountercurrent ({NECC}) and the {S}outh {E}quatorial {C}urrent ({SEC}) (south of 2.5°{S}) were determined between the ridges and troughs of the transport function. {T}he stochastic errors in bimonthly mean transports were 1-2 {S}verdrups on the most sampled tracks. {M}ean transports of the {NEC} and {NECC} increase regularly with longitude from east to west. {T}he {NECC} has a large annual cycle with a transport-maximum during northern fall and winter. {S}easonal variations of the {NEC} are small. {S}easonal variations of the {SEC} are slightly larger, and they have considerably different phase from track to track. {T}he variation of thermal structure associated with the currents is described. {T}he results of this study are compared in detail to the results of earlier studies of the transports. {T}he differences between the studies are larger than the expected stochastic errors in the mean transports due to differences in the definition of boundaries of the currents and to differences in the procedure for calculating the mean annual variation. {T}he results of all the studies are summarised to facilitate future comparisons to ocean general circulation models and other applications.
