algal bloom
5.Fluorescence excitation-emission matrix spectroscopy(EEMS) was employed to characterize the dissolved organic matter(DOM) in algal bloom seawater of Jiaozhou Bay in February,2004.The relationships of DOM fluorescence characteristics with phytoplankton multiplication,dissolved organic carbon(DOC),salinity,dissolved oxygen and pH were discussed. In addition,the protein-like and humic-like fluorescence changes fore and aft cross-flow ultrafiltration(CFF) were primarily evaluated.
7.To study the effects of simulated HAB (Harmful algal blooms) on protozoan community structure, shipboard Prorocentrum donghaiense inoculation experiments (at about 106 cells L-1, equivalent to bloom density) were carried out at stations zzf1, zc18a and ra5 in the East China Sea, a frequent HAB occurrence area, on 27th April, 4th May and 8th May 2005, respectively.
