Accelerated uptake by phytoplankton of iron bound to humic acids

[摘要] ABSTRACT: Most of the dissolved iron (Fe) in seawater is complexed by organic ligands. One key issue in understanding Fe limitation in the sea is the bioavailability of different forms of Fe to marine phytoplankton. We measured Fe uptake by the coastal diatom
