AbstractThis paper conducted fluorescent spectra of dissolved organic matter of Spring China North Yellow Sea by using three-dimensional fluorescence spectroscopy (EEMs) combined with parallel factors analysis (PARAFAC). The results showed that the fluorescent dissolved organic matter (FDOM) in colored dissolved organic matter (CDOM) of North Yellow Sea could be resolved to four components. Two components, cl (260,315/425) and c2 (295,355/490) were identified as humic-like fluorescence components while c3 (275/310) and c4 (230, 290/345) were protein-like components. The different linear correlations showed different degrees of similarities in the source or the chemical constitution, the relationship of the humic-like fluorescence components were most closely, followed by protein-like components. Four fluorescent components and total fluorescence intensity (TFI) in the horizontal and vertical directions had a higher intensity in coastal area than that of the area far away from the coast. Additionally, besides terrestrial input, the seawater mass movement also affects the distribution of CDOM in North Yellow Sea. Cluster analysis not only further illustrated the TFI characteristics of different areas of the North Yellow Sea, but also reflects the overall uniformity of the CDOM. Fluorescence Index (FI), Humification Index (HIX) and Biological Index (BIX) at some extent indicated the source of North Yellow Sea CDOM and the conclusion was that the near shore side gets greater influence from terrigenous sources while the sea side is more impacted by biological activity, which matched with the prior distribution patterns of fluorescence components.
