BIOLIMITATION OF IODINE DISTRIBUTION IN ANTARCTIC OCEAN

Based on the analysis of samples collected during Sixth Chinese Antarctic Exploration,this paper discusses the geochemical distribution of iodine species and chemical forms. Special interest is directed to the relations among the iodine species, and parameters related to organism activity. The concentrations of total inorganic iodine are from 0.267 to 0.443μmol/dm3 (mostly iodate) in the surface seawater. There are closely relations between nutrients and the concentrations of iodine and iodate. The results shows dissolved organic iodine concentration distributes stably horizontally and vertically is about 10% of the total inorganic iodine. The absorption and assimilation rate of phytoplankton for iodine is about 0.17μmol/(m2·d); the associated iodine as suspended organic particulates is about 4.3μmol/m3, in which the iodine instanding crop averages 16%. The deposite rate of the particulate iodine is more than 7.2d/m, within the euphotic zone. A biogeochemical cycle model is proposed.
