Na. Bray et al., CHARACTERISTICS OF THE INDO-PACIFIC THROUGHFLOW IN THE EASTERN INDIAN-OCEAN, Geophysical research letters, 24(21), 1997, pp. 2569-2572
Five hydrographic sections across the Indonesian throughflow from the
World Ocean Circulation Experiment (WOCE) and the Java Australia Dynam
ic Experiment (JADE) are used to examine seasonal water mass and densi
ty distributions, including semiannual variation of the South Java Cur
rent. Altimetric sea surface height variations match dynamic height al
ong each WOCE cruise track remarkably well. They also reveal energetic
eddies and meanders of the current system south of Java with intrasea
sonal (60-day) changes in surface dynamic height comparable in magnitu
de to seasonal and interannual variations. Through the formation of di
screte eddies and meanders of the large-scale zonal flows, intraseason
al fluctuations account for much of the variation in water mass struct
ure between cruises.
