The first oceanographic section was made along 133°E from 20°N to 10°N from June 13-18th, and the second one from 09°N, 138°E to 00°, 149°E from June 25-28th. The warm surface water having a value of above 29°C was presented over the whole sea surface. The thermocline with the maximum vertical gradient having a value of 0.17°C/m was the shallowest near 09°N. The low salinity lower than 34.50% was presented in the surface mixed layer between 16°N and 02°N. The conspicuous transitions were formed on each side of the north and south of the low salinity water. The North Equatorial Current was recognized on the north side of 08°N ; the South Equatorial Current near the Equator ; and the North Equatorial Countercurrent in the region between 08°N and 01°N. Several step-like features and inversion layers were presented in the thermocline at the Equator. The lateral advection of water masses in the surface layer was well developed near the Equator.}, pages = {97--109}, title = {Oceanic Conditions in the Western Tropical Pacific in the Summer of 1988}, volume = {37}, year = {} }
