Generally speaking, variations of temperature and salinity in this section according to years are rather less remarkable, especially in summer quite few differences are found, with a few exceptions. However, eastward volume transport of the Kuroshio across this section in summer, referred to 1200 d. b. surface, shows large differences according to years with a maximum value of ca 39×10^6 m^3/sec in 1967 and a minimum value of ca 26×10^6 m^3/sec in 1968, while it is nearly same value of ca 30×10^6 m^3/sec in spring every year. The core of the Kuroshio seems to be situated almost always at the middle point between the border of the East China Shelf and the Ryukyu Submarine Ridge, though the width and the thickness of the current are both variable considerably from time to time. Another eastward current exists to the far south from the Kuroshio around 20°N-24°N latitude, which may be the Subtropical Countercurrent or may be not. Volume transport of this eastward current varies very much according to seasons or years, with a maximum value of ca 30×10^6 m^3/sec and a minimum value of ca 8×10^6 m^3/sec, which may suggest remarkable fluctuations of the current direction, because these values do not contain total transport but only eastward component.}, pages = {31--54}, title = {Oceanic Conditions near the Ryukyu islands III : Oceanic Conditions along 125°E in Spring and Summer of Successive Four Years, 1965-68}, volume = {20}, year = {} }
