To examine the relationship between carbon and nitrogen stable isotope (SI) ratios (δ13C and δ15N) of zooplankton, we analyzed samples collected bimonthly from March to October 2009, from the euphotic layers of the Oyashio current along the A-line in the western North Pacific. Isotopic ratios of hig...
