外文摘要：The absorption properties of chromophoric dissolved organic matter (CDOM) in the East China Sea (ECS) and the waters off eastern Taiwan (WET) were studied during May 2014. CDOM absorption coefficient (a(280)) and spectral slope (S275-295) revealed considerable spatial variations. In the ECS, the values of a(280) and S275-295 presented a reverse distribution pattern. In the WET, a(280) values were generally low while S275-295 values were generally high. Vertical distributions of a(280) and S275-295 also varied in different regions. Terrestrial input, phytoplankton production, sediment release or photobleaching may be responsible for the dynamics of CDOM. Relationships among CDOM related parameters could partly support this conclusion. a(280) were also used to trace different water masses and the result showed that the influence of Changjiang Diluted Water could reach the outer shelf of the northern ECS, and that the Kuroshio Current had a strong influence on the middle shelf of the southern ECS.
