The north-south section of the atmospheric concentration of ^<85>(Kr) over the Pacific is first reported. The most striking feature of the section is a large concentration difference at the geographical position of the intertropical convergence. The ^<85>(Kr) concentration in the air over the North Pacific ranged from 22 to 23pCi m^<-3> and in the South Pacific 16pCi m^<-3>. The concentration differences between two hemispheres is about 6pCi m^<-3>. Five year records from land stations in Japan indicate that the annual increase is about 1pCi m^<-3>y^<-1>. It seems that the amount of the southward transport of ^<85>(Kr) from the northern hemisphere is nearly equilibrated with that of radioactive disintegration and/or dissolution of ^<85>(Kr) into the ocean in the southern hemisphere.
