We present the water column profiles (surface to 2000 m depth) for dissolved inorganic radiocarbon ( 14 C DIC ) from 2 stations in the Kuroshio region including the Kuroshio large meander (LM) of 2004–2005. Surprisingly, the Δ 14 C DIC value varied up to 125‰ in the intermediate layer, especially near 600 m depth. In addition, the Δ 14 C DIC value was approximately − 150‰ at 200 m depth at the northern station of Kuroshio in August 2005. This value is ∼100‰ less than other Δ 14 C DIC values for the same depth. In comparison, the Δ 14 C DIC water column profiles for the southern station of Kuroshio and GEOSECS station 224 decrease down to 600 m depth and were similar below 600 m depth. Our results suggest that strong upwelling associated with the Kuroshio LM has a powerful influence on the Δ 14 C DIC water column profiles in the study region
