Vertical distributions of Iodine-129 and iodide in the Chukchi Sea and Bering Sea

Miwa, Kazuji ; Obata, Hajime*; Suzuki, Takashi

This study investigated the vertical distribution of Iodine-129 ( $^{129}$ I) which is mainly produced by European nuclear reprocessing plants in the Chukchi Sea and Bering Sea. $^{129}$ I was found to be distributed almost uniformly in fallout level, and an increasing in $^{129}$ I concentration levels caused by high $^{129}$ I water inflow from the Atlantic Ocean was not observed. Additionally, we revealed the vertical distribution of iodide, one chemical form of iodine, from the Bering Shelf area to the Chukchi Sea for the first time. The increasing tendency of iodide near sea bottom was observed.
