Abstract

The aim is to quantify 9 trace metals (Al, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb) in seawater samples. Seawater samples were collected in R/V Hakuho Maru cruise KH-14-6 in Subtropical North Pacific Ocean (At 165°E and around the Mariana Trench), and cruise KH-17-3 (Subarctic North Pacific Ocean). Dissolved (dM) and total dissolvable (tdM) trace metals concentrations were quantified. Labile particulate (lpM) concentrations were calculated from the difference of tdM and dM. The vertical distribution of dM and lpM will be presented in the conference.
