A cold water of 10°C climbs up to ca 250m depth at ca 5°N. Temperature of the core of salinity maximum of higher than 35% extending to the north from the southern latitudes in a layer around 150m depth is ca 23°C. Low salinity is found around 5°N. Oxygen content in a layer above 100m is ca 4cc/l and below the layer the vertical gradient is strong to the north of 3°N. The South Equatorial Current is found in a region to the south of 2°N and below the Current an eastward flow exists. It is difficult to distinguish the Equatorial Undercurrent from the Equatorial Countercurrent flowing eastwards in a region to the north of the South Equatorial Current. The amount of the eastward volume transport above a depth of 400m, based on direct measurement, is ca 93 million m^3/sec and that of westward is ca 25 million m^3/sec.}, pages = {82--86}, title = {Report of the Kagoshima-maru IGY Cruise, 1958}, volume = {8}, year = {} }
