Atmospheric deposition of trace metals to the western North Pacific Ocean observed at coastal station in Japan

Okubo, Ayako; Takeda, Shigenobu*; Obata, Hajime*

To understand the atmospheric input of trace metals to surface seawaters, the total deposition samples were collected simultaneously from three coastal station in Japan. The observed flux was within the lower limit of the previous estimation based on a model. Except for Sc and Fe, all the elements showed a increasing tendency toward dissolution with decreasing the pH. We calculated the Sc-normalized enrichment factors. The increasing tendency toward dissolution with decreasing the pH was higher for Al than that of Fe.
