Abstract

Abstract

In order to issue the biogeochemistry of dissolved organic carbon (DOC) in the western Pacific Ocean, the absorbance and fluorescence spectrums of chromophoric dissolved organic matter (CDOM) were studied in the upper waters from November 2015 to January 2016. Results showed that, the absorbance coefficient a(320) of CDOM ranged at 0.01-1.07 m^-1 with an average of 0.18 m^-1. The higher a(320) were located in the 100-200 m water layers, while the lower values were in the surface water layers, which may due to the photochemical decomposition process. Parallel factor analysis was applied to analyze the three-dimensional fluorescence spectrum of CDOM, including one humic-like component of C2 (252(310) nm/405 nm) and two protein-like components of C1 (224(276 nm)/335 nm) and C3(224(260)nm/300 nm). The humic-like components accounted for 11%-22% in fluorescence intensity, while protein-like components dominated in 78%-89%. Protein-like components, which were composed of tryptophan-like and tyrosine-like compounds, contributed substantially to the fluorescence intensity. The higher CDOM fluorescence was observed in the boundaries between ocean currents and circulation formative regions. And oceanic currents controlled the general CDOM distribution in large scale in study area. In addition, positive relationships were discovered among the relative contents of CDOM, CDOM fluorescence, temperature, salinity, DO and nutrients in the upper water layers of the western Pacific Ocean. It was suggested that the CDOM production were more closely related with primary production in upper water layers.
