The internal cycling of zinc in the ocean
WebThe internal cycling of zinc (Zn) in the ocean has been a longstanding mystery. Particularly puzzling is the strong correlation between Zn and silicate (SiO44−), but not phosphate (PO43−), even though Zn is involved with cell functions that regulate PO43− uptake and are unrelated to SiO44− uptake.
