  • The distribution of dissolved inorganic iodine in the

    1. Introduction. In oxic oceans, dissolved iodine exists as both iodate and iodide, at a total concentration of about 0.45 μM. A small concentration of dissolved organic iodine has been reported in inshore waters (Truesdale, 1975, Luther et al., 1995, Wong, 1991).Particulate iodine is found at concentrations of up to about 1 nM in near-surface waters (Wong et al., 1976).
