Relative zinc concentrations in the upper 1,000 m of the northeastern tropical Pacific Ocean were measured by p H‐controlled differential anodic stripping voltammetry (DASV) aboard ship. The waters above 125 m are significantly lower in zinc content than those between 125 and 1,000 m. A substantial fraction of the measured zinc appears to be adsorbed on particulate matter >0.45 µ . The adsorption can be reversed by lowering the p H to 5.6 with CO 2 gas.
