Abstract In this paper, it is explained that the spectrometric data in situ measured by PIS-Btype spectral radiometer, which is made by Shanghai Institute of Technical Physics. Chinese Academy of Sciences, and surface water samples taked with water bucket are used during the test of the water under spectral survey in important East Sea area. After the sediment samples and spectrometric data are treated, the correlation between the spectral reflectance and suspended sediments is quantitatively established by the least square method. The result expresses that the relationship between the spectral reflectance and surface suspended sediments concentration shows exponential function and 555 nm and 670 nm wavelengths are the best wavebands to remotely measure surface suspended sediments in East Sea.
