SGD in Huanghai

In 2016, (Liu et al. , 2017b)used the 228Ra mass balance method to investigate SGD flux on the south coast of the Yellow Sea. As a semi-closed sea area, the SGD input of yellow Sea is (1.3 ± 1.0)*1012 m3/yr, which is 5.9 ± 3.9 times of the total inflow of other rivers. In the southern part of the Yellow Sea, SGD also had a huge impact on the environment. Its DIN, DIP and DSi were (487 ± 384) ×109 mol/yr, (2.8 ± 2.2) ×109 mol/yr and (313 ± 259)×109mol/yr, respectively, which were considered by scholars as important factors for the outbreak of cyanobacteria in the Yellow Sea.
