| Abstract: | In order to better understand the spatial and temporal distribution of dissolved cadmium in Prydz Bay, east Antarctica, seawaters were sampled by CTD during the CHINARE-25 cruise (Oct. 2008 - Apr. 2009) and the concentrations of cadmium were analyzed by AAS (Atomic Absorption Spectrometry) in the clean laboratory. Together with the data of macronutrients and chl.a from the same cruise, the relationship between cadmium and biological process was studied. The results showed that the concentrations of Cd in the surface water had a good relationship with chl.a and biologicl process was the important factor that influenced the distribution of dissolved Cd in the surface water. Linear relationship was found between dissolved Cd and phosphate in the surface water and the high ratio of Cd/P at the edge of ice shelf was most probably due to ice melting, vertical distribution of Cd was similar to those of macronutdent such as phosphate and was affected by decomposition of organic particals. The temporal change of dissolved Cd in upper layer was slight and tide probably had influence on the change. |
