Description
Seawater were collected at six points, 0deg to 48degN around 165degE. Dissolved inorganic carbonates was reduced into graphite. The ratio C-11/C-12 was measured by the accelerator mass analyzer. 14C concentration was calculated from δ13C value calculated from the 13C/12C ratio. 14C resulting from the nuclear weapon test was calculated by comparing estimated 14C and real 14C concentration. It was compared with that in 1970s. 14Cbomb has dissolved into North Pacific Intermediate Water in Arctic latitude, which has moved to Mid-latitude. (A. Yamamoto)
