INTERANNUAL VARIABILITY OF THE OYASHIO CURRENT

I. A Zhigalov, E. V. Samko, and Yu. V. Novikov

The results of Russian—Japanese oceanological surveys carried out in the northwestern Pacific in August 1989—1999 are discussed. The calculations of geostrophic velocities in the section crossing the Oyashio in the area southeast of Iturup Island are analyzed. Data on spatial-temporal variability of structure and volume transport of the Oyashio are presented, and a conclusion is made about considerable interannual fluctuations of the volume transport. A maximum of intensity of the Oyashio Current was in 1995 and 1996.
