Abstract
A study of tin concentrations in the North Atlantic Ocean has revealed concentrations much lower than previously reported. Concentrations of dissolved tin in surface water are in the range of non-detectable (< 1.5 pM) to 16 pM. Almost all depth profiles have maxima in tin concentrations from 50 to 200 m depth. These maxima can be as high as 16 pM. In most depth profiles, dissolved tin is at or below detection limits at depths exceeding 1000 m.
