Abstract Nickel (Ni), copper (Cu), zinc (Zn), and cadmium (Cd) are trace metals classified as nutrient-type elements in the oceans. This study reports full-depth distribution of dissolved (d) Ni, Cu, Zn, Cd during 2017 GEOTRACES Japan KH-17-3 cruise, aiming to augment knowledge chemical oceanography highlight east–west differences subarctic Pacific Ocean. The linear relationship dCd PO 4 reflects a concurrent influence ocean circulation biogeochemical cycling. For other metals, dM/PO ratios reflect preferential uptake by phytoplankton, fluvial inputs, reversible scavenging, release from bottom. suggest supplies Ni Cu marginal seas North American continent. East–west gradient dZn/PO ratio shows severer depletion dZn surface water eastern Pacific, which is consistent with previous research. We calculate enrichment factor ( EF ) that dM/dAl normalised M/Al crust for dNi, dCu, dZn, dCd. values substantially high central part Subarctic Gyre, implying presence anthropogenic atmospheric input via westerly wind.
